MOTOR-DRIVEN POWER STEERING UNIT

摘要

The invention relates to a motor-driven power steering unit, comprising an electric motor for producing an auxiliary steering force in a steering system that couples a steering handle to the wheels of a vehicle. The power steering unit assists the rotation of the steering wheel by controlling an electric current fed to the electric motor based on steering information. Said unit also comprises a steering angle detection device and an overload protection device to reduce the electric current fed to the electric motor, wherein the overload protection device reduces the electric current fed to the electric motor if the steering angle detected exceeds a predetermined angle.
