  Electric Power Steering (EPS) System The Electric Power Steering (EPS) system works by applying torque to steering gear of a car based on a sensor that detects steering angle and torque. The electrical control unit (ECU) monitors the vehicle’s overall speed and sends a voltage signal to the electric motor. As the electric motor delivers torque in response to the steering angle, the system is most effective when a driver is moving at low speeds. It also provides with better control of a vehicle. The most common type of Electric Power Steering (EPS) system uses a three-phase electric motor that runs on DC voltage modulated with pulse width. This motor operates without mechanical brushes and allows for high torque application at low revolutions per minute . EPS also works with a computer to compensate for any irregularities in the steering system. The EPS warning light illuminates when the system is not working properly. The first performance requirement for Electric Power Steer...

  Electric Wheelchair A Electric Wheelchair is an Electric Vehicle that propels the user forward by means of the power of batteries. These vehicles are characterized by a front- or back-wheel drive system. These wheelchairs are usually equipped with a manual tilt and recline system to enable the user to change positions as needed. The first electric wheelchairs that were commercially produced were heavy manual folding-frame wheelchairs powered by lead-acid batteries. These wheelchairs were primitive and had no programmability. The seating systems were typically sling seats and back upholstery. Those designs offered limited postural support and were not designed for use by wheelchair users with limited mobility. The design of an Electric Wheelchair has changed dramatically over the past decade, from simple push-button controls to complex micro processing. A direct drive system delivers power to a single pair of wheels, with additional sets of wheels providing stability. These typ...
