The invention provides a vehicle U-turn control method and device and a vehicle. The method comprises the steps that firstly, after it is detected that a crawling U-turn function is started, a vehicle acquires the angle of a steering wheel, and whether the vehicle meets a preset crawling U-turn condition or not is determined according to the steering angle of the steering wheel; when the crawling U-turn condition is met, the vehicle obtains transmission gear information and transfer case gear information, the target vehicle speed of the vehicle in the crawling U-turn process is obtained according to the information, and then the brake pressure of inner side front wheels and the brake pressure of inner side rear wheels are calculated and obtained when the vehicle turns around according to the angle of a steering wheel and the wheel base and the wheel track of the vehicle. Finally, the vehicle is controlled to conduct crawling turning according to the target vehicle speed, the brake pressure of the inner side front wheel and the brake pressure of the inner side rear wheel. By means of the scheme, the turning radius of the vehicle can be reduced, automatic speed control in the turning process is achieved, and the turning driving smoothness and controllability are improved.
本申请提供一种车辆调头的控制方法、装置及车辆。该方法包括:首先在检测到蠕行调头功能开启后,车辆采集获取转向盘角度,根据转向盘转角度,确定车辆当前是否满足预设的蠕行调头条件。在满足蠕行调头条件时,车辆获取变速器档位信息和分动器档位信息,并根据该信息获取车辆在蠕行调头过程中的目标车速,然后根据转向盘角度,车辆的轴距以及轮距,计算获取车辆调头时的内侧前轮的制动压力和内侧后轮的制动压力。最后根据目标车速,内侧前轮的制动压力以及内侧后轮的制动压力控制车辆进行蠕行调头。通过本方案可以减少车辆调头转弯半径,实现转弯过程自动控速,提高了调头行驶平顺性和可控性。
