Sensors collect data such as current vehicle speed, turning angle, terrain conditions, crosswind acceleration, and torque applied to the steering wheel. [ 5 ] [ 6 ] [ 7 ] The electric motor is a device powered by electricity that adds torque in the form of mechanical energy to a steering gear(the gear responsible for translating the rotation of ...
