A method for controlling a vehicle, the vehicle having a steer by wire and
a brake by wire system is disclosed. The method includes sensing a yaw
rate, a steering wheel rate of rotation, and a throttle position. Further,
the method includes comparing the yaw rate, steering wheel rate of
rotation, and the throttle position to a thresholds. Thereafter, a
determination is made as to whether the yaw rate, the steering wheel rate,
and the throttle position is greater than, or less than the respective
thresholds. An operating mode of the vehicle is changed from a nominal
control mode to a performance control mode when the yaw rate is greater
than a first threshold yaw rate and less than the second threshold yaw
rate, steering wheel rate of rotation is greater than the threshold
steering wheel rate of rotation, and the throttle position is greater than
the threshold throttle position.
