The invention discloses a vehicle control method. The method is applied to the field of Internet of Vehicles and comprises the steps of obtaining a current working condition of a vehicle; acquiring a first parameter of a power battery of the vehicle in response to the current working condition of the vehicle as a dormant working condition; determining whether the power battery is abnormal or not based on the first parameter; obtaining a first communication signal of the vehicle and a second parameter of the power battery in a first preset time period in response to the abnormality of the power battery or the current working condition of the vehicle is not the dormancy working condition, and judging the power battery based on the first communication signal and the second parameter to obtain a first judgment result, the second parameters at least comprise the voltage, the temperature and the insulation resistance value of the power battery, the gas pressure in the battery pack, the gas concentration in the battery pack and the expansion torque of the single battery; and controlling the vehicle based on the first judgment result and the current working condition. According to the invention, the technical problem of low control accuracy of thermal runaway of the vehicle power battery in the prior art is solved.
本发明公开了一种车辆控制方法。该方法应用于车联网领域,包括:获取车辆的当前工况;响应于车辆的当前工况为休眠工况,获取车辆的动力电池的第一参数;基于第一参数,确定动力电池是否发生异常;响应于动力电池发生异常,或车辆的当前工况不为休眠工况,获取车辆的第一通讯信号以及第一预设时间段内动力电池的第二参数,并基于第一通讯信号和第二参数对动力电池进行判断,得到第一判断结果,第二参数至少包括:动力电池的电压、温度、绝缘阻值、电池包内气体压力、电池包内气体浓度,以及电池单体膨胀力矩;基于第一判断结果和当前工况,对车辆进行控制。本发明解决了相关技术中对车辆动力电池的热失控的控制准确率低的技术问题。
