What does PS mean in a car?
1 Answers
When PS is displayed on a car, it indicates a malfunction in the power steering system. Here is the relevant information: 1. Electric Power Steering System: The electric power steering system is developed on the basis of the traditional mechanical steering system. It uses the power generated by an electric motor to assist the driver in steering operations. 2. Components: The system mainly consists of three major parts: signal sensing devices (including torque sensor, angle sensor, and speed sensor), steering assistance mechanism, and electronic control unit. The motor only operates when assistance is needed. When the driver operates the steering wheel, the torque angle sensor generates corresponding voltage signals based on the input torque and steering angle, while the speed sensor detects the vehicle speed signal. The control unit then issues commands to control the motor operation based on the voltage and speed signals, thereby generating the required steering assistance.
