    [0001] The present invention relates to a device and a method for controlling a power supply of a vehicle differential speed controller and, more particularly, to a device and a method for controlling a power supply of a vehicle differential speed controller and, more particularly, to a device and a method. to maintain the power supply of a vehicle differential speed controller according to a parking brake signal. With reference to FIG. 7, for a vehicle equipped with differentials, such as an off-road vehicle, a front wheel differential 801 and a rear wheel differential 802 are provided and controlled respectively by a front differential speed controller 704. and a rear differential speed controller 705 in an unlocked state or a locked state. When the front wheel differential 801 and the rear wheel differential 802 are in the unlocked state, the wheels on the left and right of the vehicle can rotate at different speeds. On the other hand, when the front wheel differential 801 and the rear wheel differential 802 are in the locked state, the wheels on the left and right of the vehicle can rotate at the same speed or synchronously. When the driver parks the vehicle and pulls on the parking brake lever 703, the transmission shaft connected to the wheels is locked to prevent the drive shaft from rotating. With respect to the control of the front wheel differential 801 and the rear wheel differential 802, the front differential speed controller 704 and the rear differential speed controller 705 acquire an operating power of a vehicle power supply 701 by a power switch 702. If the driver cuts the power switch 702, the front differential speed controller 704 and the rear differential speed controller 705 immediately stop operating and are maintained in their last state. prior to shutting off the power switch 702. Therefore, the front wheel differential 801 and the rear wheel differential 802 can still be maintained in the unlocked state. As a result of the unlocked state of the front wheel differential 801 and the rear wheel differential 802, the wheels on the right and left of the vehicle can still rotate. In the case of certain specific terrains, such as a steep hill, even if the parking brake is pulled and the drive shaft is locked, the vehicle may be at risk of accident due to a vehicle movement from wheels in rotation. The present invention aims to provide a device and method for controlling a power supply of a vehicle differential speed controller ensuring that a vehicle differential remains in a locked state after the vehicle power failure. For this purpose, the device for controlling a power supply of a vehicle differential speed controller comprises an input voltage pin, an output voltage pin, an input voltage regulation circuit, a trigger circuit , a control circuit and a relay.
    [0002] The input voltage pin is adapted to be connected to a vehicle power supply of a vehicle to receive an input voltage. The output voltage pin is connectable to at least one differential speed controller. The input voltage regulating circuit is connected to the input voltage pin for receiving the input voltage and converting the input voltage to an operating voltage. The trip circuit is connected to the input voltage regulating circuit, receives the operating voltage and a parking brake signal generated by activating a parking brake of the vehicle, and outputs a trip signal for a period of time. preset upon receipt of the parking brake signal. The control circuit is connected to the trip circuit for receiving the trip signal and a power switch signal from the vehicle, and outputs a control signal upon receipt of any of the switch signal of the vehicle. power supply and trigger signal. The relay is connected between the input voltage pin and the output voltage pin, is connected to the control circuit to receive the control signal, and is controlled by the control signal to be activated so that the output voltage pin supplies a voltage to the at least one differential speed controller. To achieve the foregoing objective, the method for controlling a power supply of a vehicle differential speed controller comprises the steps of: detecting a switching state of a power switch; when the power switch is off, stopping supplying an output voltage to a differential speed controller; detecting an activation state of a parking brake; after the power switch is turned off, determining whether or not to activate the parking brake to generate a parking brake signal; generating a trigger signal; after detecting the parking brake signal, generating the trip signal for a preset time; and restoring the supply of the output voltage; during the preset time, the restoration of supply of the output voltage to the differential speed controller to resume the operation of the differential speed controller in preset time and change a state of operation of the differential speed controller to a predetermined one. locked state. With the foregoing apparatus and method, when a driver cuts off the vehicle power and activates the parking brake, the parking brake signal activates the trip circuit to generate a trip signal for the active control circuit to operate. the relay in a short period of time depending on the trigger signal. During the activation time of the relay, the device supplies the output voltage to the differential speed controller so that the differential speed controller has sufficient time to switch an operating state of a vehicle differential corresponding to a differential. Locked state, thus preventing the wheels on the left and right sides of the vehicle from rotating asynchronously. The invention therefore relates to a device for controlling a power supply of a vehicle differential speed controller, characterized in that it comprises: an input voltage pin adapted to be connected to a power supply of vehicle for receiving an input voltage; An output voltage pin adapted to be connected to at least one differential speed controller; an input voltage regulator circuit connected to the input voltage pin for receiving the input voltage and converting the input voltage to an operating voltage; a trip circuit connected to the input voltage regulating circuit, receiving the operating voltage and a parking brake signal generated by activating a parking brake lever of the vehicle, and outputting a trip signal during a preset time upon receipt of the parking brake signal; a control circuit connected to the trip circuit for receiving the trip signal and a power switch signal from the vehicle, and outputting a control signal upon receipt of any of the power switch signal and the trigger signal; and a relay connected between the input voltage pin and the output voltage pin, connected to the control circuit for receiving the control signal, and controlled by the control signal to be activated so that the input pin output voltage supplies a voltage to the at least one differential speed controller. The trip circuit may include a time adjustment circuit for adjusting the preset time. The tripping circuit may be a monostable tripping circuit delivering the tripping signal having a high level in the preset time. The time adjustment circuit may be an RC circuit formed of a resistor and a capacitor serially connected to each other. When the control circuit receives neither the power switch signal nor the trip signal, the relay may be disabled by the control signal from the control circuit. The output voltage pin can be connected to a front differential speed controller and a rear differential speed controller of the vehicle. The invention also relates to a method for controlling a power supply of a differential speed controller, characterized in that it comprises the following steps: the detection of a switching state of a switch of food ; when the power switch has been turned off, stopping supplying an output voltage to a differential speed controller; detecting an activation state of a parking brake; after switching off the power switch, determining whether the parking brake is activated or not to generate a parking brake signal; generating a trigger signal; after detecting the parking brake signal, generating the trip signal for a preset time; and restoring the supply of the output voltage; during the preset time, the restoration of supply of the output voltage to the differential speed controller to resume the operation of the differential speed controller in the preset time and change a state of operation of the differential speed controller to a predetermined one. locked state. Other objects, advantages and novel features of the invention will become more apparent upon reading the following detailed description, taken in conjunction with the accompanying drawings. In these drawings: FIG. 1 is a block diagram of a device for controlling a power supply of a vehicle differential speed controller according to the present invention, applied to a vehicle control system; Figure 2 is a block circuit diagram of the device for controlling a power supply of a vehicle differential speed controller of Figure 1; Figure 3 is a circuit diagram of a trigger circuit of the device for controlling a power supply of a vehicle differential speed controller of Figure 2; Figure 4 is a circuit diagram of a control circuit of the device for controlling a power supply of a vehicle differential speed controller of Figure 2; Figure 5 comprises multiple waveforms associated with signals from a power switch, an output voltage, a parking brake, and the trigger circuit of Figure 2; Figure 6 is a flowchart of a method for controlling a power supply of a vehicle differential speed controller according to the present invention; and Figure 7 is a block diagram of a conventional control system for a vehicle differential speed controller. Referring to Figure 1, a device 1 for controlling a power supply of a differential speed controller according to the present invention is connected to a vehicle power supply 101, a power switch 102, a power lever parking brake 103 and at least one differential speed controller. In the present embodiment, the at least one differential speed controller comprises a front differential speed controller 104 and a rear differential speed controller 105. Referring to Figure 2, the device 1 for controlling a power supply of a differential speed controller comprises an input voltage regulating circuit 10, a trigger circuit 20, a control circuit 30 and a relay 40. A pin coming out of the device 1 comprises a pin of input voltage 51 and an output voltage pin 52. The input voltage pin 51 is connected to the vehicle power supply 101. The output voltage pin 52 is connected to the front differential speed controller 104 and the rear differential speed controller 105. The vehicle power supply 101 is generally a battery providing a direct current (DC) having a DC input voltage. Wine. The input voltage regulating circuit 10 is connected to the vehicle power supply 101 by the input voltage pin 51 to receive the input voltage Vin and convert the input voltage Vin to a power of operation for a continuous power supply. The trip circuit 20 is connected to the input voltage regulating circuit 10 to receive the DC operating power and is connected to the parking brake lever 103 to acquire a parking brake signal Si. When the brake lever When a parking signal 103 is pulled, a trip signal S2 is generated and outputted from an output terminal to the control circuit 30. Referring to FIG. 3, the trip circuit 20 is a trip circuit. monostable having a time adjustment circuit 22 for configuring a preset time. Upon receipt of the parking brake signal 51, the monostable trip circuit changes an output voltage level, for example by changing an original low level signal to a high level signal during the preset time. The monostable trip circuit may be formed of an integrated circuit (IC) 555 IC. One of the input terminals serves to receive the parking brake signal Si, and two other input terminals are connected to an RC circuit formed of a resistor R1 and a capacitor C1 connected in series. one to another. The RC circuit serves as a time adjustment circuit 22, and the values of the resistor R1 and the capacitor C1 can be adjusted to change the preset time.
    [0003] Referring to Fig. 4, the control circuit 30 includes two input terminals for respectively receiving the trigger signal S2 from the trigger circuit 20 and a power switch signal S3 from the switch d. 102. An output terminal of the control circuit 30 is connected to the relay 40 to provide a control signal for enabling or disabling the relay 40. When none of the power switch signal S3 and the trigger signal S2 is present, the control circuit 30 deactivates the relay 40. When one of the supply switch signal S3 and the trigger signal S2 is present, the control circuit 30 activates the relay 40. The relay 40 is connected in series between the input voltage pin 51 and the output voltage pin 52. When the relay 40 is activated according to the availability of the power switch signal S3 and the signal of declination S2 enablement, the input voltage Vin 20 supplied by the vehicle power supply 101 passes through the relay 40 to provide an output voltage V'i by the output voltage pin 52. Conversely, when the relay 40 is deactivated, the output voltage pin 52 does not deliver current. Referring to FIGS. 1 and 5, when the vehicle is traveling and the power switch 102 is turned on, a high level power switch signal S3 can be received, so that the relay 40 is activated and the output voltage pin 52 can continuously supply the output voltage V'i for the front differential speed controller 104 and the rear differential speed controller 105 to operate normally.
    [0004] H When the vehicle is stopped, the driver turns off the power switch (for example at time t1), and the power switch signal drops from a high level signal to a low level signal. In turn, the control circuit 30 does not send the control signal to the relay 40, and the relay 40 is therefore deactivated. As a result, there is no output voltage V. When the driver further pulls on the parking brake lever 103, the parking brake signal S1 switches from a high level signal to a level signal. low (for example at time t2), the trip circuit 30 immediately switches the trigger signal S2 from a low level signal to a high level signal and keeps the trigger signal S2 high for the preset time of t2 at t3. During the preset time, the control circuit 30 delivers the control signal to the relay 40, so that the relay 40 is activated again during the preset time of t2 to t3, and the output voltage V't is again provided during the pre-established time. Thus, the front differential speed controller 104 and the rear differential speed controller 105 can acquire sufficient power for the preset time of t2 to t3 to control a front wheel differential 201 and a rear wheel differential 202 of the vehicle to that they enter a locked state. Referring to Fig. 6, a method for controlling a supply of a vehicle differential speed controller according to the present invention comprises the following steps. Step S601: Detect a switch state of a power switch. If the power switch has been turned off, stop supplying an output voltage to a front differential speed controller 104 and a rear differential speed controller 105. Step S602: Detect an activation state of a parking brake. After disconnecting the power switch, determine if the parking brake has been activated to generate a parking brake signal. Step S603: Generate a trigger signal.
    [0005] After detecting the parking brake signal, generate the trip signal for a preset time. Step S604: Restore supply of output voltage. During the preset time, restore supply of the output voltage to the front differential speed controller 104 and the rear differential speed controller 105 to resume operation of the front differential speed controller 104 and the differential speed controller. Rearward 105 and 20 change an operating state of each of the front differential speed controller 104 and the rear differential speed controller 105 to a locked state in the preset time. In sum, the device 1 for controlling a supply of a vehicle differential speed controller can supply power to the front differential speed controller 104 and the rear differential speed controller 105 in a short preset time, when the The driver cuts off the vehicle power supply and activates the parking brake, so that the front wheel differential 201 and the rear wheel differential 202 have enough time to enter the locked state, thereby preventing asynchronous rotation. wheels. Although many features and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is for illustrative purposes only. Changes can be made to the details, in particular on the shape, size and arrangement of 10 pieces, without departing from the scope of the invention.
