Braking force control device of vehicle

专利摘要:
A combined vehicle antiskid and load-dependent brake control system in which digital control of the individual wheel brake pressure regulating valves is provided. These regulating valves may be operated individually or on a per axle basis to vary the brake pressure independent of the operator-controlled brake valve device. The load-dependent brake control portion of the system includes electronic control circuitry that is subject to the output signal of sensors, which monitor pressure supplied by the brake valve device, actual brake cylinder pressure and the load supported by the vehicle rear axle, in order to operate the regulating valve of at least one wheel brake cylinder such as to cause the wheel brake pressure to follow a predetermined curve that differs from a normal brake pressure buildup curve.

(54) DEVICE FOR REGULATING VEHICLE FORCE OF VEHICLE
one
The invention relates to automobiles, building-up and can be used in an air brake system as a device that regulates braking forces at different weights and for various vehicles.
Anti-blocking devices are used in braking systems, the task of which is to match the braking force with the coefficient of adhesion between the car's wheels and the road surface.
In general, the brake cylinders of the front and rear wheels of the vehicle are connected to the main control valve via a modulator, which is controlled by signals from the logic unit. The pressure in the brake cylinders changes periodically, and the pressure increases to the point of locking the wheel, i.e. in the case of achieving maximum compliance with the braking torque and the braking force torque on the wheel.
In brake systems, load-dependent regulators are used, which match the braking with various vehicle loads during service.
Mr. braking. One of the requirements for such adjustments is to optimize the specified distribution of braking forces for any vehicle load.
In braking systems, braking regulators are also installed, taking into account the redistribution of axial load during vehicle braking.
ten
It is possible to combine in the brake system with an antilock braking regulator with a mechanical drive.
However, such a system is
15 difficult in constructive execution that reduces reliability in operation ...
To eliminate these drawbacks, the control of the braking force, depending on the axial load and the load of the car, is generally carried out in the same way as the control from wheel locking by means of electronic measuring and logic
25 units associated with a regulating device.
