    DK 2006 00104 U4
    The invention relates to a retrofitted cruise control for controlling engines, and in particular to a vehicle pilot with a cruise control module for the control of a user and a control element for producing control signals. The accelerator, such as a gas pedal, is operated mechanically by the driver and is equipped with an electronic signal output. An engine control system or the like uses the signals from the signal output to perform electronic control of the engine's power regulation in the same way as throttle control of the engine to, for example, supply fuel to the combustion chamber of an internal combustion engine.
    Vehicle retrofits are partly known as a mechanical connection between the accelerator pedal and the power control equipment (eg throttle arm, throttle). These cruise control units consist essentially of a speed control module, an input unit for setting or loading a desired speed and a drive for controlling the accelerator pedal, in particular in the form of a servo motor and associated connections. The speed control module controls the speed according to the driver's entries through mechanical positioning of the accelerator pedal by means of the drive device. It should be emphasized that the position of the accelerator pedal is regulated through the mechanical connection to the power control equipment to regulate the power output of the engine.
    Rear-mounted cruise control is also known for vehicles that have an electric acceleration control. The electric acceleration control consists of a motor control system and a throttle arm or accelerator pedal which do not have direct mechanical connection to each other. An acceleration sensor is set on the accelerator to detect the position of the accelerator and sends an electrical signal to the engine control. Then the motor control regulates the speed by means of the motor's power control equipment corresponding to the signal from the acceleration sensor. These types of systems are referred to as "drive-by-wire". The present invention relates to such a drive-by-wire system. A retrofit cruise control of this type can be purchased in general trade. It also includes a speed control module, an input device for setting the desired travel speed and a drive for adjusting the accelerator pedal, in particular in the form of a servo motor and the necessary mechanical coupling. The speed control module controls the speed based on the driver's inputs and the mechanical positioning of the accelerator pedal with the aid of the input device. The position of the accelerator pedal is sensed and transmitted electrically to the power control equipment to control the power from the engine.
    In any of the previous solutions, when the pilot is engaged, the accelerator pedal is physically moved by a power drive, such as a servo motor, to ensure that the required acceleration of the driver will be achieved, without the driver touching the accelerator pedal. These mechanical solutions are large and, due to the space conditions of some vehicles, will be very difficult to install. In addition, from a conceptual point of view, the required servo motor and mechanical connections to the accelerator pedal in "drive-by-wire" vehicles should not be used in these vehicles, and in addition, these mechanical connections for the power drive will cause some reduction in reaction time.
    The closest known technique is in the following documentation describing a retrofitted cruise control system which operates on the drive-by-wire principle and does not have a throttle pedal drive device: 1) newspaper article "Parts Maker cruising along as speed Controls get tougher ”from“ The Age ”, dated June 2, 2003; 2) Autron Electronics press release" Black Box assures safety ", dated July 2001; 3) Product Release Notice "Vito and Sprinter CDI cruise control", dated January 14, 2002; 4) Internet message at www.autron.com.au regarding the differences between cruise control systems of the type "electronic connection" and "pedal pull" (undated).
    The creation
    The primary purpose of the production is to provide an improved retrofit navigable pilot to overcome the disadvantages of the current retrofit cruise control. The generation of claim 1 provides an improved cruise control structure to solve the aforementioned problems.
    With the current generation - hereinafter referred to as retrofitted cruise control - a middle module emits the cruise control's electronic control signal to affect e.g. throttle on the engine that should! is controlled so that the intermediate module is positioned between a mechanically actuated throttle with an electronic output signal and an electronic motor control, and the intermediate module is arranged so that its output signal is of such shape as to make it out of the control signal from the cruise control or from the accelerator or from a combination of both, In one embodiment (not shown in the drawing), the speed control module and the intermediate module can be combined in a common housing.
    With the generation, a constant driving speed is achieved with a fully electronic, fast-reacting and reliable retrofitted solution, without having to intervene in the dedicated motor control of the vehicle or engine (electronic control unit or motor control). The retrofitting solution needs fewer components and is also easier to install than current solutions because no major mechanical in- 3 DK 2006 00104 U4 staliation is required. The space requirement is smaller and the installation site can be chosen relatively freely. Also, the installation time is quite short. There is no mechanical wear.
    The aforementioned as well as the components described in the claims and embodiments to be used for the production are not subject to special exceptions, restrictions or restrictions in terms of their size, design, material selection and technical principle, and thus the selection criteria known in the field of application will be found. unlimited use.
    Further objects, new features, further details, features and advantages of the invention will become apparent from the subclaims, as well as from the following description and accompanying drawings, which show, by way of example, an embodiment of the invention. The drawing shows:
    FIG. 1 is a block diagram of a cruise control according to the invention, wherein the cruise control is integrated into a "drive-by-wire" system.
    In FIG. 1 shows a "drive-by-wire" system comprising an accelerator, usually in the form of a gas pedal 30, with a signal output 31, a motor control system 50 for a specific motor, and a power control equipment 20. The system can e.g. may be defined together with an internal combustion engine, electric motor, fuel cell engine or other drive motors 21 e.g. for vehicles. Without the cruise control, at signal output 31, depending on the position of driver actuated accelerator 30, an output signal 32 is generated which is passed to motor control system 50. Motor control system 50 converts output signal 32 and controls power control equipment 20 via a preferably electrical connection to reach and maintain it. of the driver desired speed. As a rule, the mechanisms of the signal processing of the engine control system 50 are known only by authorized persons, because each engine control, intended by the automakers for use with specific engine performance systems, is supplied as a so-called "black-box". However, the output signal 32 from signal output 31 is dependent on the position of the accelerator 30 and is well known for the same reason.
    The retrofitted cruise control according to the invention comprises a metal module 40, as well as the known speed control module 10 and a control element 12, which is well known as a loading unit in various variants. By means of this the cruise control can provide a certain speed. The control element 12 is mounted in the vehicle cab in the vicinity of the steering wheel. The control element 12 may also be placed in the gear lever knob to minimize distraction of the driver. This type of control has its own inventive meaning.
    The intermediate module 40 is connected - process oriented - between the accelerator pedal 30 and the engine control system 50, so that the signal output 31 is not directly connected to the motor control 50 but to the intermediate module 40, from which signals are forwarded to the motor control system 50. The speed control module 10 is also connected to the intermediate module 40. Speed control module 10 is also connected (electrically or by radio wave, infrared or otherwise wireless) to the control element (12).
    The connection between the signal output 31 of the accelerator pedal 30 and the motor control 50 is constituted by a connecting cable 60, which (at the factory side) is provided at its two ends with engine or vehicle specific connectors 61, 62, for easy mounting and universal applicability of the cruise control according to The generation is the intermediate electrical connections of the intermediate module 40 made with additional connecting cables 70 A, B with a connection connector 70 which is preferably T-shaped. The coupling connector 70 is provided at its T-shaped ends with connectors 71, 72 specific to the engine or the vehicle, so that the intermediate connections of the connecting cables 70 A, B can be established seamlessly between the accelerator pedal and the engine control system, either (as shown in dashed line) to signal output 31 on throttle 30 or (as shown in full lines) to signal input 51 on motor control 50.1, in the first case, signal output 31 is electrically connected to intermediate module 40 via connection connector 70 ', connection cables 70A 70B1, connector bushing or connector 73, and connector 41. 41 is part of the intermediate module and independent of a specific vehicle, so that the intermediate module 40 can be used universally, and incorporation into a particular vehicle only requires the connecting cables 70A ', 70B' to be connected by the connecting connector 70 'which will be placed between the signal output 31 and the associated socket connector 6V, In the second case, the connector 62, 51 is disconnected and the connection connector 70 is coupled with its plug connectors 71, 72 between connection ports 62, 51. In both cases, the original connection cable 60 remains in its original position in the vehicle. Such T- or Y-shaped connector connectors have independent inventive significance. They may even include electronic components, and in particular such electronic or non-electronic components, which provide adaptation of a universal interface to certain vehicle makes, engine types, engine version or the like and / or to certain electronic signals between the engine control and the accelerator pedal, or which adapts these signals to a universal interface.
    With the cruise control in its disengaged status, the intermediate module 40 sends the output signal 32 from the signal output 31 to the engine control 50, thereby maintaining the vehicle's speed control in accordance with the position of the accelerator pedal. If the cruise control function is switched on by the control element 12 and a speed is programmed (selected), then the intermediate module 40 sends a signal to the motor control system 50, which is a control or shift signal 11 coming from the speed control module 10 or is a mixed signal of the output signal. 32 and the shift signal 11, which mix signal is associated with the position of the accelerator pedal. Thereby also mechanical components such as e.g. a servo motor for moving the accelerator pedal 30 is omitted. Furthermore, the intermediate module 40 receives the signals from the signal output 31.
    When the driver depresses the accelerator pedal 30 to increase the speed to more than the set speed of the cruise control, the intermediate module 40 responds, according to one of the embodiments of the generation, and sends a signal to the engine control 50 to increase the speed. The overall process is carried out with the cruise control switched on as long as the increased speed is within certain safety limits for the cruise control's safety function.
    When the driver wants to drive at a speed loaded in the cruise control and therefore does not want to operate the accelerator 30, the intermediate module 40 sends a signal to the motor control 50 on the basis of the shift signal 11. Since the motor control signal is usually not constant due to different power requirements to the motor (e.g., when traveling uphill or downhill at constant speed), the intermediate module 40 must "know" which signal mode to send to the motor control system 50 for e.g. to increase the power for uphill driving. In order to preserve its universal character, the generation has advantageously shown that the intermediate module 40 independently learns what mode is required and sends the necessary signal. In that case, it is possible that the output 32 of the signal output 31 is "known" by the intermediate module 40. Therefore, only a short learning phase is required to learn a rule, and a full spectrum of all possible signal outcomes will be transmitted to the intermediate module 40 when the accelerator pedal pressed down. Thereby different learning modes may be programmed to ensure an effective and safe learning tool. Any specific or new software for self-learning or other features can be added during production or assembly of the intermediate module and / or its cabling or even after assembly.
    6 DK 2006 00104 U4
    In addition to the preceding feature, the intermediate module 40 may be instructed on or accommodate any specific vehicle type (s) information so that the T-shaped connecting cable for a specific vehicle will be "recognizable". This will allow the vehicle type and its control systems to be determined so that all information will be "known" by the intermediate module 40. To enable such recognition, the simplest way would be to have more multi-connector connections than necessary at the intermediate module 40 connector 41 for In doing so, a "cable connection" obtained by connecting cables 70A ', 70B' will be "specific" for a particular type of vehicle or engine, and will be "recognized" by the intermediate module 40. The leg pattern of the connecting connector 73, which is also defined with more multi-pin pins than is necessary in each case, then applies to a specific connecting cable 70A, 70B or 70A ', 70B'. In addition to this, more complex possibilities can be envisaged, in particular sensor-controlled recognition.
    The cruise control according to the invention has other properties than just controlling the speed, eg safety functions for interrupting or disengaging the cruise control, for example when the brake or accelerator pedal is depressed, by interruption action with the control element 12, by excessive engine speed, by deceleration or acceleration of the vehicle. for certain speed limits (eg 75% to 150%) and monitoring and rating of ignition status.
    The control element 12 may also have other useful functions, for example to cooperate with a readable memory 10A, so that stored speeds allowed in different traffic zones (urban driving or highway) or terrain conditions can be evoked by the push of a button (memory function). The overall system effectively prevents speeding limits as long as this feature is turned on.
    Consumers can combine the features to meet their own needs.
    In one embodiment (not shown in the drawing), the speed control module and the intermediate module can be assembled in a common housing.
    Although many features and benefits of the creation are highlighted in the foregoing description, together with details of the structure and function of the creation, the explanation serves as an illustration only. Within the framework of the production, retail changes can be made, especially in matters of form, size and placement of components to the full extent indicated by the broad meaning of the words used in the appended claims.
