The invention is suitable for the technical field of vehicle control, and provides a suspension control method, a suspension control device, a domain controller and a vehicle. The method comprises the steps that under the condition that a pre-collision signal is received and a vehicle body stability system of the vehicle is not started, the pre-collision time of the vehicle is determined; first main power needing to be output by a suspension actuator of each wheel of the vehicle is determined, the first main power is used for adjusting the suspension height of the corresponding wheel to the target height within the pre-collision time, and the target height is larger than the current height of the suspension of the wheel; and target instructions are sent to the suspension actuators, the target instructions comprise the first main power needing to be output by the corresponding suspension actuators, and the target instructions indicate the corresponding suspension actuators to output the first main power within the pre-collision time. According to the invention, the safety of the vehicle in the collision process can be improved.
本申请适用于车辆控制技术领域,提供了一种悬架控制方法、悬架控制装置、域控制器及车辆。该方法包括:在接收到预碰撞信号且车辆未开启车身稳定性系统的情况下,确定所述车辆的预碰撞时间;确定所述车辆的各车轮的悬架执行器需要输出的第一主动力,所述第一主动力用于在所述预碰撞时间内将对应所述车轮的悬架高度调节至目标高度,所述目标高度大于所述车轮的悬架所处的当前高度;向各所述悬架执行器发送目标指令,所述目标指令包括对应所述悬架执行器需要输出的所述第一主动力,所述目标指令指示对应所述悬架执行器在所述预碰撞时间内输出所述第一主动力。通过本申请可提高车辆在碰撞过程中的安全性。
