How to resolve EPS failure?
1 Answers
When the car displays EPS, it indicates an electronic power steering failure issue, and it needs to be repaired at a 4S shop as soon as possible. The classification of automotive electronic power steering systems is as follows: 1. Mechanical hydraulic power assistance: The main components of a mechanical hydraulic power steering system include a hydraulic pump, oil pipes, pressure fluid control valve, V-type drive belt, oil reservoir, etc. This assistance method converts part of the engine's power output into hydraulic pump pressure, applying auxiliary force to the steering system to enable tire steering. 2. Electro-hydraulic power assistance: In this system, the steering oil pump is no longer directly driven by the engine but by an electric motor. Additionally, an electronic control system is installed on top of the previous setup, making the steering assistance force not only related to the steering angle but also to the vehicle speed. The mechanical structure includes added hydraulic reaction devices and fluid distribution valves.
