The invention provides a vehicle body posture control method and system, a medium, a control terminal and a vehicle. The method comprises the following steps that the vehicle speed of the vehicle is obtained, and whether the vehicle is in an acceleration state or a deceleration state or not is judged; when the vehicle is in the acceleration state or the deceleration state, the left front acceleration, the right front acceleration and the rear axle acceleration of the vehicle body in the Z direction are obtained; calculating a vehicle body pitch angle rate gradient based on the left front acceleration, the right front acceleration and the rear axle acceleration; and when the absolute value of the vehicle body pitch angle rate gradient is not smaller than a preset threshold value, a damping continuously-adjustable shock absorber is adjusted based on the vehicle body pitch angle rate gradient and shock absorber electromagnetic valve current matched with the vehicle speed, so that vehicle body posture control is achieved. According to the vehicle body attitude control method and system, the medium, the control terminal and the vehicle, the electromagnetic valve current of the damping continuously-adjustable shock absorber is controlled based on the vehicle body pitch angle rate, and then control over the vehicle body attitude in the vehicle acceleration and deceleration process is achieved.

    本公开提供一种车身姿态控制方法、系统、介质、控制终端及车辆,包括以下步骤:获取车辆的车速并判断车辆是否处于加速状态或减速状态;当所述车辆处于所述加速状态或所述减速状态时,获取车身Z向的左前加速度、右前加速度和后轴加速度;基于所述左前加速度、所述右前加速度和所述后轴加速度计算车身俯仰角速率梯度;当所述车身俯仰角速率梯度的绝对值不小于预设阈值时,基于所述车身俯仰角速率梯度和所述车速匹配的减振器电磁阀电流调节阻尼连续可调减振器,以实现所述车身姿态控制。本公开的车身姿态控制方法、系统、介质、控制终端及车辆基于车身俯仰角速率来控制阻尼连续可调减振器的电磁阀电流,进而实现对车辆加减速过程中车身姿态的控制。
