  • Electric power steering system
    Patent number: 4875540
    Abstract: A system having a motor operatively connected to a steering system for reducing the steering effort. The system is provided with a torsion torque sensor provided for detecting torsion torque generating in the steering system in steering operation. In response to the output signal of the torsion torque sensor, an assist signal is produced. A return torque signal dependent on the lateral acceleration exerted on a motor vehicle is generated. The return torque signal is added to the assist signal, thereby operating the motor to return a steering wheel.
