车辆俯仰姿态控制方法、装置、设备、车辆、介质及产品
By acquiring the vehicle's historical speed and acceleration/deceleration parameters, the target control parameters are determined, and the shock absorbers and hydraulic pumps in the active suspension are controlled. This solves the problem of controlling vehicle pitch in the active suspension, improving driving comfort and safety.

AI Technical Summary
Existing technologies lack methods for controlling active suspension to reduce vehicle pitch, which affects driving comfort.
By acquiring the vehicle speed and acceleration judgment parameters within the first preset time period before the current moment, and the deceleration judgment parameters within the second preset time period before the current moment, it is determined whether there is a target condition in the preset vehicle state judgment conditions. Based on the target condition, vehicle data is acquired, and the operation of the front axle dual-valve shock absorber, the rear axle dual-valve shock absorber, the front axle hydraulic pump, and the rear axle hydraulic pump is controlled to control the vehicle pitch attitude.
It achieves effective control of the active suspension, reduces vehicle pitch, and improves driving comfort and safety.
