Wheel slip control system

摘要

A wheel slip control system has a vehicle speed detector for detecting a running speed of a vehicle; a driving wheel rotating condition detector for detecting an actual driving wheel rotating speed of the vehicle and the acceleration thereof; an advance driving wheel speed computer for calculating an advance driving wheel speed using as parameters the above actual driving wheel rotating speed and acceleration thereof; a second throttle valve provided in an intake passage in a position upstream or downstream of the position where a first throttle valve interlocked with a vehicle accelerator pedal is located; a driver for opening and closing the second throttle valve; and an opening/closing controller for determining a target throttle position on the basis of the detected vehicle running speed and the advance driving wheel speed and controlling the driver so that an actual throttle position of the second throttle valve approaches the above target throttle position. According to above-mentioned characteristics, it is possible to attain superior acceleration and controllability, and the air fuel ratio and fuel consumption are held in a good condition.
