Abstract
During occurrence of slippage at drive wheels, a traction controller calculates a feedforward term of a desired drive engine torque as a sum of an accelerating resistance torque and a running resistance torque determined immediately before the occurrence of slippage. The traction controller calculates a feedback term of the desired drive torque as a function of a slip error from a desired value and determines a target engine torque in response to the feedforward and feedback terms and a speed ratio established in a transmission. The traction controller alters an engine torque modifier in the form of a throttle arranged upstream of an accelerator controlled throttle.
