Traction slip control system for a motor vehicle with all-wheel drive

摘要

Traction slip control system for a motor vehicle with all-wheel drive, comprising the following features:– a motor (1), a transmission (3), a front axle differential (9) and a rear axle differential gear (13), a central differential (5), in order to provide a driving force to the front - and rear wheels to be sectioned, wheels (11a, 11b, 11c, 11d), with a respective wheel speed (30a to 30d) for detecting the wheel rotational speed of each of the front - and rear wheels (11a to 11d), a longitudinally acceleration to the receptor (32), a brake-pressure control device (25) for the independent control of a to each wheel brake pressure applied, a motor power control means (26) for controlling the output power of the motor, a higher-level control unit (40) for the brake-pressure control device (25) and the motor power control means (26),– a vehicle speed computer (41), in order to provide a reference vehicle speed (v_r) of the vehicle on the basis of a wheel with the lowest wheel speed (ω) and the longitudinal acceleration (x) to calculate, for which reason the change in the wheel speed (ω) of the selected wheel is correlated with the longitudinal acceleration and change values to the respective preceding vehicle speed are added and the summation with..
