Title: Brake pressure control unit for motor vehicle - couples pressures proportional to braking unit pedal force with ABS for dynamic stable behaviour
Inventor: STEINER MANFRED DIPL ING
IPC: B60T8/175
Filed: 1991-01-29
Abstract: A sensor unit responds to the instantaneous operating condition of the braking unit (13) to produce a characteristic electrical output signal which is a measure for the amount of braking power desired by the driver or vehicle retardation. The output signals are fed to an electronic control unit which processes these and produces signals for a brake pressure adjusting unit by which at least one pressure is coupled at least to the front wheel brakes that is higher than the logical expected value. A control of the braking pressure adjusting unit is then activated, at least in the sense of brake pressure development, if the alteration rate of the variable representing the operating position of the braking unit (13) with braking pressure build-up, exceeds a specified threshold value. The monitored condition variable is the force exerted on the brake pedal (19) or the direct correlated value of the output pressure produced in the braking unit (13) in direct proportion to the pedal force. At least one pressure sensor (78,79) produces characteristic electric output signals for pressure in at least one of the front wheel brakes (14,16) and pref. at least one pressure sensor (81) produces characteristic output signal for at least one of the rear wheel brakes. USE/ADVANTAGE - Multi-circuit braking system for vehicle with ABS and ASR. Method corrected control of automatically controlled braking operation with simple space saving construction.
