Development of New Control Methods to Improve Response of Throttle Type Traction Control System 920608

A description is made of new control methods to improve response of wheel slip regulation. These methods enabled a new Traction Control (TRC) system based on throttle control rather than brake pressure to be developed. Major points are as follows:
  1. (1)
    Use of fuel injection cut-off to minimize delay
  2. (2)
    Additional adaptive throttle control logic
By these means, a response nearly equal to that with brake pressure control is achieved at lower cost and with a considerable weight saving. Furthermore, the system, by suppressing noise and vibration, enhances the driver's control ability.
