Abstract
A lane keep assist system for an automotive vehicle includes an electric power steering assembly that is responsive to an output of the control system, the motor applying a torque to a part of a steering gear to steer the vehicle along a highway. The lane keep assist system assists a driver in keeping the vehicle in a lane of a highway, in which the control circuit comprises A PID Controller which receives at an input a target lane position for the closed-loop control system and provides as an output a control signal for a motor of the electric power steering assembly. The controller is arranged in a closed loop with the motor configured to minimise an error value indicative of the difference between the target lane position and the actual lane position of the vehicle.
