Abstract: A vehicle control system includes a first error module that determines a first yaw error based on a difference between a yaw rate of the vehicle and a target yaw rate. A second error module determines a second yaw error based on the first yaw error and a target yaw error. A target yaw error module sets the target yaw error based on a skill level of a driver of the vehicle. An adjustment module selectively one of increases and decreases a target adjustment when the second yaw error is greater than a first predetermined threshold. An actuator control module, in response to the increase in the target adjustment, actuates a dynamics actuator of the vehicle.

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.

Abstract: A method of calculating an engine torque request value for a vehicle includes a vehicle controller receiving an regeneration torque request value corresponding to a regeneration torque to be generated by an energy recovery mechanism. The vehicle controller further receives a desired acceleration value, and calculates the engine torque request value based on the regeneration torque request value and the desired acceleration value. The vehicle controller may then operate the engine in accordance with the engine torque request value.

Abstract: A method of controlling a transmission includes initiating a temporary neutral mode of the transmission, in which at least one clutch of the transmission is disengaged to prevent power flow through the transmission, when an upshift paddle selector and a downshift paddle selector are both engaged within a pre-defined engagement time window. At least one of the upshift paddle selector and the downshift paddle selector is held in their respective engaged positions to maintain the temporary neutral mode of the transmission. The temporary neutral mode of the transmission is ended when both of the upshift paddle selector and the downshift paddle selector are disengaged, by re-engaging the at least one transmission clutch that was disengaged to initiate the temporary neutral mode.

Abstract: A method of controlling a vehicle having a first axle driven by an internal combustion engine, and a second axle independently driven by an electric device includes determining if the accelerator pedal is disposed in a depressed position or in a non-depressed position, and determining if a brake pedal is disposed in a depressed position or in a non-depressed position. An axle control strategy for controlling energy regeneration of an energy storage device is selected based on the position of the accelerator pedal being in either the depressed position or the non-depressed position, and the position of the brake pedal being in either the depressed position or the non-depressed position. A control signal is communicated to at least one of the first axle or the second axle to implement the selected axle control strategy.

Abstract: A method of controlling a vehicle includes calculating a desired deceleration limited regeneration torque request based on a requested deceleration input from a driver. If current dynamic operating conditions of the vehicle are in a performance region that permits an increase to the regeneration torque request, the desired deceleration limited regeneration torque request is increased based on a regeneration torque overhead, to define a modified axle regeneration torque request. Modified torque values are output based on the modified axle regeneration torque request. If the torque control values will cause an estimated yaw rate that is less than a target yaw rate, then the modified torque values are applied. Otherwise, the modified torque values are re-defined until the estimated yaw rate is not greater than the target yaw rate, and the re-defined values of the modified torque values are applied.

The vehicle operating conditions depend, at least in part, on operator commands and the current SOC of the energy storage system.

Abstract: A method of controlling a vehicle includes calculating a desired deceleration limited regeneration torque request based on a requested deceleration input from a driver. If current dynamic operating conditions of the vehicle are in a performance region that permits an increase to the regeneration torque request, the desired deceleration limited regeneration torque request is increased based on a regeneration torque overhead, to define a modified axle regeneration torque request. Modified torque values are output based on the modified axle regeneration torque request.

Otherwise, the modified torque values are re-defined until the estimated yaw rate is not greater than the target yaw rate, and the re-defined values of the modified torque values are applied.
