Can You Continue Driving When the EPS Light Is On?
1 Answers
EPS light illumination generally indicates a fault in the electric power steering system. If accompanied by abnormalities such as heavy steering, unusual steering noises, steering wheel vibrations, or poor steering wheel return ability, you should not continue driving. If none of the above-mentioned abnormalities occur, you can safely stop the vehicle and restart the engine to attempt a resolution. Below is an introduction to EPS: 1. EPS stands for Electric Power Steering, a power steering system that directly relies on an electric motor to provide assistive torque. Compared to traditional hydraulic power steering (HPS), EPS offers numerous advantages. EPS mainly consists of a torque sensor, vehicle speed sensor, electric motor, reduction mechanism, and electronic control unit (ECU). 2. The working principle of EPS involves the torque sensor being connected to the steering shaft. When the steering shaft rotates, the torque sensor activates, converting the relative angular displacement between the input and output shafts caused by torsion into an electrical signal sent to the ECU. The ECU then determines the motor's rotation direction and assistive current based on signals from the vehicle speed sensor and torque sensor, thereby achieving real-time control of power steering. Consequently, it can easily provide varying levels of motor assistance at different speeds, ensuring light and flexible steering at low speeds and stable, reliable steering at high speeds.
