  • Setting vehicle center in electronic power steering system
    Patent number: 11661101
    Abstract: The disclosure provides a steering system for a vehicle. The steering system may include a steering rack and an electronic power steering (EPS) system. The EPS system may include an actuator that assists movement of the steering rack, a torque sensor; an angle sensor; and an EPS system controller. The EPS controller may be configured to determine a steering rack center point indicating a center of the steering rack between opposite maximum steering angles. The EPS controller may be configured to determine a vehicle center zero point. The EPS controller may be configured to store the vehicle center zero point in response to determining that the vehicle center zero point is within a threshold of the steering rack center point.
