What is the correct interpretation of PS in cars?

[DiMaci]

PS is illuminated when starting the vehicle and turns off while driving. It is the indicator light for the power steering system. If it remains lit during driving, it indicates a fault in your vehicle's power steering system. The electric power steering system is a type of power steering system that relies on an electric motor to provide auxiliary torque. Compared to traditional hydraulic power steering systems, the electric power steering system is more convenient. Depending on the installation position of the motor, it can be further classified into column-assist type, pinion-assist type, and rack-assist type. If the mechanical part of the power steering system is damaged, it needs to be repaired at a professional 4S shop. If the electronic part is damaged, the fault code should be read first, and then the cause of the fault can be identified based on the fault code. Generally, electronic faults are mostly related to the steering angle sensor. Its advantages include significantly reducing the vehicle's fuel consumption, enhancing the driver's sense of control, improving steering followability, optimizing steering return characteristics, and increasing the vehicle's stability.
