The new EPS offers a more comfortable and controlled ride by reducing steering effort at low speeds and harnessing its electric motor’s inertia to dampen out most of the bump steer and kickback caused by impacts to the wheel. Electrically driven, the motor is controlled by an ECU that uses input from a vehicle speed sensor and torque sensor to determine the amount of assistance provided by the system. The system works immediately and doesn’t put a power drain on the engine. It operates as soon as the ignition key is turned to the "ON" position.
