The invention discloses a control method and device for a vehicle chassis and a vehicle, and relates to the technical field of vehicle chassis control, the vehicle chassis comprises a vehicle frame, a plurality of steering axles and a plurality of driving axles, the steering axles and the driving axles are installed at the bottom of the vehicle frame at intervals in the front-back direction, and all the driving axles and all the steering axles can be independently controlled. The control method of the vehicle chassis comprises the following steps that in the running process of a vehicle, the motor output power of a first drive axle and/or the motor steering angle of a second steering axle are/is obtained; according to the motor output power and/or the motor steering angle, all the drive axles and all the steering axles are controlled to work, the drive axles and the steering axles are controlled to work independently, the drive axles and the steering axles do not affect one another, large part loss and energy waste caused by simultaneous movement of multiple shafts are reduced, and the service life of the drive axles and the steering axles is prolonged. Therefore, the steering precision control is improved and the loss of parts is reduced under different working conditions and road conditions.

    本发明公开了一种车辆底盘的控制方法、控制装置和车辆,涉及车辆底盘控制技术领域,其中,车辆底盘包括车架、以及沿着前后向间隔安装于车架底部的多个转向桥和多个驱动桥,各驱动桥和各转向桥均可独立控制,车辆底盘的控制方法包括以下步骤:在车辆行驶中,获取第一驱动桥的电机输出功率和/或第二转向桥的电机转向角度;根据电机输出功率和/或电机转向角度,控制各驱动桥和各转向桥工作,通过控制多个驱动桥和多个转向桥各自独立工作,多个驱动桥和多个转向桥之间相互不会影响,减少多轴同时运动所造成较大的部件损耗及能源浪费,以适应不同工况和路况下,提升转向精度管控,减少部件损耗。
