摘要:
An engine control system comprises a derivative module and a slip remediation module. The derivative module determines a mathematical derivative of a driven wheel speed of a vehicle. The slip remediation module, when the mathematical derivative is more negative than a predetermined deceleration, at least one of disables regenerative braking being performed by one or more electric motors, increases an axle torque request, and unlocks a torque converter.
