Stability is an important factor in vehicle safety. Yaw rate error can be used to improve stability. Yaw rate is measured through a yaw rate sensor. Desired yaw rate can be determined from vehicle conditions and driver input. The yaw rate error is calculated by subtracting the measured yaw rate from the desired yaw rate. Based on this calculation, yaw torque target signals can be calculated to apply torque to the wheels through the application of one or more electric drivelines. The application of torque can provide side-to-side and front-to-rear torque biasing to improve stability. Furthermore, the application of torque at specific times can improve braking and launch capabilities.
