The invention relates to the technical field of new energy automobiles, in particular to a vehicle torque arbitration and response coordination control method and device, a vehicle and a medium, and the method comprises the steps that at least one electric braking torque request is obtained; based on the priority of the at least one electric braking torque request, the electric braking torque request with the highest priority in the at least one electric braking torque request serves as a target electric braking torque request of the vehicle; and the current delay duration is obtained, and the target electric braking torque request is delayed according to the current delay duration, so that the wheel end of the vehicle executes electric braking and hydraulic braking at the same time. Therefore, the problems that in the braking process of the vehicle, time difference exists between the electric braking torque and the hydraulic braking torque under special conditions, torque execution is not coordinated, and the most pause of the vehicle is likely to occur are solved, electro-hydraulic braking response consistency is guaranteed, the whole vehicle is comfortable and safe to use, and the service life of the vehicle is prolonged. And the conditions of'pause 'and the like caused by response time difference under special conditions are effectively avoided.
本申请涉及新能源汽车技术领域,特别涉及一种车辆扭矩仲裁和响应协调控制方法、装置、车辆及介质,其中,方法包括:获取至少一个电制动扭矩请求;基于至少一个电制动扭矩请求的优先级,将至少一个电制动扭矩请求中优先级最高的电制动扭矩请求作为车辆的目标电制动扭矩请求;获取当前延时时长,并根据当前延时时长延迟目标电制动扭矩请求,使得车辆的车轮端同时执行电制动和液压制动。由此,解决了车辆在制动过程中电制动扭矩和液压制动扭矩在特殊情况下存在时间差,导致扭矩执行不协调,容易出现车辆最“顿挫”的问题,保证电液制动响应的一致性,使整车使用的舒适和安全,有效避免在特殊情况下由于响应时间差引起的“顿挫”等情况。
