How to adjust the steering force level of Volvo S60?
1 Answers
Volvo S60 steering assistance type: electric power steering. The steering force can be adjusted to three levels (high, medium, low) in the car settings to achieve the desired steering wheel rotation ease. Detailed introduction is as follows:1. Electric Power Steering (EPS) system: A power steering system that directly relies on an electric motor to provide auxiliary torque. Compared with traditional hydraulic power steering systems, EPS consists of a torque sensor, vehicle speed sensor, electric motor, reduction mechanism, and electronic control unit (ECU). 2. EPS can be divided into two types based on power source: hydraulic electronically controlled power steering system and electric electronically controlled power steering system. (1) Hydraulic EPS: An electromagnetic valve, vehicle speed sensor, and electronic control unit are added to the traditional hydraulic power steering system. The ECU controls the electromagnetic valve based on the detected vehicle speed signal, enabling continuous adjustment of the steering power amplification ratio to meet the steering assistance requirements at both high and low speeds. (2) Electric EPS: Uses a DC motor as the power source. When the car turns, the torque sensor detects the steering wheel torque and intended turning direction, and the signal is sent to the ECU via the data bus. The ECU then sends action commands to the motor controller based on the transmitted torque, intended direction, and other data. The motor outputs the corresponding amount of steering torque as needed to provide power steering assistance. If no steering is performed, this system does not operate.
