  • Publication number: 20170072941
    Abstract: A method of determining a regeneration schedule for a vehicle having an internal combustion engine, an electric machine, and a plurality of yaw rate actuators. The method includes determining an allowable yaw rate change based on dynamic conditions of the hybrid vehicle, a combined mitigation potential of the yaw rate actuators, and a regeneration torque command that causes an actual yaw rate change. Determining the regeneration torque command includes comparing the allowable yaw rate change to the combined mitigation potential. If the combined mitigation potential is less than the allowable yaw rate change, the regeneration torque command causes or limits the actual yaw rate change to be lower than the allowable yaw rate change. If the combined mitigation potential is greater than the allowable yaw rate change, the regeneration torque command causes or limits the actual yaw rate change to be substantially equal to the allowable yaw rate change.

  • Patent number: 8718868
    Abstract: In accordance with exemplary embodiments, a system and method are provided for using tire temperature for dynamically adjusting active chassis systems of a vehicle. The method comprises determining a tire temperature value for at least one tire of a vehicle using at least one sensor and adjusting at least one active chassis system of the vehicle responsive to the tire temperature value. The system comprises a chassis having an engine providing power to tires to propel the vehicle. At least one active chassis system is configured to control braking, power applied or control inputs to the tires, and a controller is configured to determine a tire temperature value for adjusting the at least one active chassis systems. The at least one active chassis systems are adjusted responsive to the tire temperature value provided by the controller to control braking, power applied or control inputs to the tires.
