Abstract:
A traction control system for a vehicle comprising:an internal combustion engine connected to a transmission, the engine equipped with a fuel rate controller responsive to a first control signal for applying a variable amount of drive torque to at least one driven wheel through a drive train,a brake system for applying braking torques to said drive wheels in response to a second control signal,an anti-skid control module connected to supply said first signal to said fuel rate controller and further connected to supply said second control signal to said brake system, said antiskid control module being responsive to a third control signal having a value indicating the estimated magnitude of said drive torque,means coupled to said fuel rate controller for generating a first value indicative of the amount of wheel torque generated by said internal combustion engine,means coupled to said engine for generating a second value proportional to the rate of change of the operating speed of said engine and indicative of the amount of wheel torque produced by the inertial movement of said engine;means coupled to said transmission for generating a third value indicating a torque ratio as a function of the speed ratio of the transmission indicative of the amount of wheel torque produced by said transmission; andmeans for combining the first, second, and third values to form said third control signal.
