The power steering rack is connected to the steering gear and steering wheel, and is responsible for converting the driver's steering instructions into actual steering actions of the wheels. Traditional mechanical steering requires a lot of force, while the power steering makes steering easier.

The work of the electric power steering system begins with the steering force sensor (Torque Sensor). When the driver turns the steering wheel, the sensor monitors the rotational torque on the steering wheel in real time. This information is transmitted to the vehicle's electronic control unit (ECU), and the ECU determines how much steering assistance is needed based on this information.

If your vehicle is equipped with a hydraulic power steering system, the condition of the hydraulic oil is crucial. Over time, the hydraulic oil may become dirty, lose viscosity, or even bubble, resulting in a decrease in the efficiency of the steering system. Therefore, regularly checking the quality of the hydraulic oil is the key to maintaining soft steering.

The reasons for the failure of electric power steering are: 1. Electrical system failure 2. Steering sensor failure 3. Control module (ECU) failure 4. Electric power motor failure 5. Power system problem 6. Mechanical problem 7. Temperature change 8. Moisture intrusion

The manual steering system relies entirely on mechanical transmission, and there is no power steering device in the system. The steering force is directly applied by the driver and transmitted to the wheels, so there is no need for a power steering pump.

In summary, the most efficient steering system should be the electric power steering system (EPS). This is because it performs well in energy efficiency, response speed and driving experience.

Mercedes-Benz offers electric power steering in many of its models. For example, Mercedes-Benz's C-Class, E-Class and S-Class models have all adopted electric power steering technology.

When the electric power steering system fails, the vehicle may experience the following situations: steering becomes difficult, steering response is delayed, the vehicle cannot maintain a straight line, the driver warning system is activated, and emergency control capabilities are reduced.

Around 1975, almost all new cars in the US market were equipped with power steering systems, and in the European and Japanese markets, this technology gradually became a mainstream configuration. It can be said that the late 1970s was an important milestone in the popularization of power steering systems.

Open the owner's manual and find the vehicle specifications or technical parameters section. Generally, the type of power steering system will be listed here. If the manual specifically mentions "hydraulic power steering system" or "electronic power steering system", then you can determine the vehicle's equipment.
