It can be roughly divided into three categories:
(1) One is a mechanical hydraulic power steering system;
(2) One is the electronic hydraulic power steering system;
(3) Another electric power steering system.
Pressure sensor is a device or device that can feel the pressure signal and convert the pressure signal into an available output electrical signal according to a certain law. The pressure sensor usually consists of a pressure sensing element and a signal processing unit.
This system works regardless of whether the car is steering or not, and when the steering speed is low, the hydraulic pump needs to output more power to obtain a larger help. Therefore, to a certain extent, resources are wasted.
