Electric Power Steering

Electric Power Steering

Electric Power Steering (EPS) is a full electric system, which reduces the amount of steering effort by directly applying the output from an electric motor to the steering system. It can solve the problems associated with hydraulic power steering [4].

Working of EPS

The electronic control unit (ECU) of EPS analyzes the assisting power required based on the steering wheel torque applied by the driver along with the wheel position and speed of traction. The EPS motor reduces the steering torque required from the driver by rotating a steering gear.

As advancement in electronic steering, efforts are made to eliminate the mechanical linkage and convert to pure electronically controlled steering, which is called steer-by-wire. This works by transmitting digital signals to remote electric motors which in turn steer the vehicle.
