Abstract
A wheel slip control system includes wheel speed sensors that generate wheel speed signals and a control module that controls torque production of at least one of an engine and an electric motor and that detects a negative wheel slip based on the wheel speed signals. The control module increases torque production of at least one of the engine and the electric motor when the negative wheel slip is detected.
