Abstract
An apparatus for determining acceleration of a motor vehicle includes an acceleration sensor for generating a signal representing acceleration of the motor vehicle, wheel speed sensor means for generating wheel speed signals indicating wheel speeds of individual wheels of the motor vehicle, and a first arithmetic unit for determining a mean value of the output signal of the acceleration sensor over a predetermined period in the running state of the motor vehicle in which the motor vehicle is making a substantially straight drive at a substantially constant speed on a substantially level ground surface during the aforementioned predetermined period, to thereby output a signal indicating the mean value, and a second arithmetic unit for determining acceleration of the motor vehicle by subtracting the mean value from the output of the acceleration sensor. An anti-skid control apparatus for a motor vehicle for controlling braking forces applied to individual wheels of the motor vehicle on the basis of differences between a vehicle speed and wheel speeds in order to prevent the wheels from being locked. The vehicle speed is determined by integrating the output of the second arithmetic unit of the acceleration determining apparatus.
