Abstract
A system for determining an angular position of a pair of steerable wheels of a vehicle having a plurality of wheels can include a yaw rate sensor, a pair of wheel speed sensors and a controller. The yaw rate sensor can be configured to output data representative of an angular velocity of the vehicle about a vertical axis of the vehicle. Each of the pair of wheel speed sensors can be configured to output data representative of a rotational velocity of a respective one of the plurality of wheels. The controller can be in electrical communication with each of the pair of wheel speed sensors and the yaw rate sensor. The controller can be configured to determine a first steering angle based on data received from the yaw rate sensor, to determine a second steering angle based on data received from the plurality of wheel speed sensors, and to select one of the first steering angle and the second steering angle for use in manipulating various vehicle parameters, including torque vectoring parameters, among other parameters.
