  • Power hop anticipation and mitigation
    Patent number: 10926771
    Abstract: Longitudinal acceleration, intended travel angle, wheel speed, and requested drive torque signals are measured for a vehicle. The longitudinal acceleration, intended travel angle, wheel speed, and requested drive torque signals are then evaluated. A brake torque is calculated as a function of a propulsive torque, wherein the propulsive torque is produced by a power source for the vehicle. The brake torque is applied when the longitudinal acceleration signal exceeds a longitudinal acceleration threshold, the intended travel angle signal is between intended travel angle limits, the wheel speed signal is less than a minimum speed threshold, the requested drive torque signal exceeds a requested drive torque threshold, and a torque threshold is exceeded.
    Type: Grant

  • Method of traction control for a motor vehicle
    Patent number: 9707967
    Abstract: A method of traction control for a vehicle. Lateral and longitudinal accelerations are measured for a vehicle. A maximum supportable drive torque for a first wheel of the vehicle is calculated as a function of the lateral and longitudinal accelerations. A commanded vectoring brake torque is applied to the first wheel using a brake device. The commanded vectoring brake torque is an amount by which a driveline torque delivered to the first wheel exceeds the maximum supportable drive torque.
