What type of power steering does the Lavida use?
2 Answers
All currently available Lavida models are equipped with electric power steering. Below are the relevant details: 1. The full English name for Electric Power Steering is Electronic-Power-Steering, abbreviated as EPS. It utilizes power generated by an electric motor to assist the driver with steering. While the structural components of EPS may vary between different vehicles, they are generally similar. It typically consists of a torque (steering) sensor, electronic control unit (ECU), electric motor, speed reducer, mechanical steering gear, and battery power source. 2. The basic working principle is: The torque sensor is connected to the steering shaft (pinion 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 electrical signals sent to the ECU. The ECU then determines the rotation direction of the motor and the magnitude of assist current based on signals from the vehicle speed sensor and torque sensor, thereby achieving real-time control of power steering.
The Lavida uses electric power steering, and I've been driving this car for several years, particularly fond of its light and effortless feel. When starting, the steering wheel turns lightly, making parking and U-turns in crowded urban areas effortless, as if there's an invisible hand helping you control the direction. The system detects your steering intentions through electronic sensors, with the motor providing assistive power, eliminating the complex structure of traditional hydraulic power steering pumps, which means it's more energy-efficient. I often drive long distances, and on the highway, the steering feels stable and precise when taking curves. Maintenance is also straightforward, mostly involving electrical circuit checks, and issues are rarely reported. However, it's important to note that electric power steering relies on the battery and wiring; if the steering wheel feels stiff after the car has been parked for too long, it might be due to battery aging or sensor issues.
