  • Patent number: 8000872
    Abstract: An anti-skid brake control system and its control method for vehicle has a signal collection unit and an electronic control unit. The electronic control unit includes a data receiving module, a data processing module and a data control module. The data receiving module receives the data collected by the signal collection unit. The data processing module calculates sideslip angles and slip rates for wheels. The data control module sets target slip rates based on the slip rates corresponding to the friction coefficient ? for different sideslip angles. The device emits control commands after comparing the calculated slip rate to the set target slip rate, so that the ABS control is real time.
