The embodiment of the invention relates to the technical field of vehicle control, and discloses a vehicle body posture adjustment control method, which comprises the following steps of: in response to a mode control instruction sent by a target vehicle ECU (Electronic Control Unit), adjusting the motion state of a vehicle based on the mode control instruction; acquiring the transverse acceleration, the longitudinal acceleration and the deflection angular velocity of the target vehicle in the movement process under the corresponding vehicle movement state; determining attitude information of the corresponding target vehicle based on the transverse acceleration, the longitudinal acceleration and the deflection angular velocity, and matching the attitude information with a pre-configured attitude control strategy to determine a vehicle body control instruction; and performing vehicle body attitude control on the target vehicle according to the vehicle body control instruction. According to the vehicle body posture adjustment control method in the embodiment, the vehicle body posture in the off-road mode is monitored so that the implementation motion posture of the vehicle can be estimated, the vehicle body posture is controlled based on the posture estimation result, and the vehicle running stability is guaranteed.

    本发明实施例涉及车辆控制技术领域,公开了一种车身姿态调整控制方法,包括:响应于通过目标车辆ECU发出的模式控制指令,并基于模式控制指令来对车辆运动状态进行调整;在相应的车辆运动状态下获取目标车辆在运动过程中横向加速度、纵向加速度和偏转角速度;基于横向加速度、纵向加速度和偏转角速度来确定相应目标车辆的姿态信息,将姿态信息与预先配置的姿态控制策略进行匹配以确定车身控制指令;根据车身控制指令来对目标车辆进行车身姿态控制。本发明实施例中的车身姿态调整控制方法其通过对处于越野模式下的车身姿态进行监测以实现对车辆的实施运动姿态进行预估,并基于姿态预估结果来实现对车身姿态的控制,保证车辆行驶的稳定性。
