Abstract

A navigation system (30) for a vehicle, the vehicle including left and right motors (22, 24) for respectively causing rotation of left and right wheels and left and right motor drives(26, 28) for respectively driving the left and right motors, the navigation system including: an electronic gyroscope (36) mountable to the vehicle; and a control unit (32) configured to: receive an output signal from the gyroscope; derive a yaw angular velocity from the gyroscope output signal; derive a vehicle turning direction from the gyroscope output signal for non-zero yaw angular velocities; and cause the motor drives to apply a relative speed difference between the motors according to the yaw angular velocity and vehicle turning direction to thereby compensate for a change in vehicle heading.
