The invention relates to the technical field of vehicles, in particular to a vehicle speed limiting method and device, a vehicle and a storage medium. The method comprises the steps that whether a current vehicle meets a preset vehicle speed limiting condition or not is judged, and if the current vehicle meets the preset vehicle speed limiting condition, the vehicle speed is limited; obtaining the current temperature of a storage battery of the current vehicle, the current power supply voltage of the storage battery and the on-state of a plurality of low-voltage loads of the whole vehicle, and matching an optimal discharge curve from a plurality of preset discharge curves according to the current temperature, the current power supply voltage and the on-state of the plurality of low-voltage loads, and calculating the residual discharge time of the storage battery according to the optimal discharge curve, and adjusting the vehicle speed of the current vehicle to a preset minimum safe vehicle speed within the residual discharge time. Therefore, the problem that vehicle power is lost due to the fact that the vehicle speed is not limited or the vehicle speed is limited improperly when the electric quantity of the storage battery cannot be obtained is solved, the electric quantity of the storage battery is prevented from being too low, guarantee is provided for driving safety of a user, and traffic accidents are reduced.
本申请涉及车辆技术领域,特别涉及一种车辆的车速限制方法、装置、车辆及存储介质,其中,方法包括:判断当前车辆是否满足预设的车速限制条件,若当前车辆满足预设的车速限制条件,获取当前车辆的蓄电池的当前温度、蓄电池的当前供电电压和整车的多个低压负载的开启状态,根据当前温度、当前供电电压和多个低压负载的开启状态从预设的多个放电曲线中匹配最优放电曲线,根据最优放电曲线计算蓄电池的剩余放电时间,在剩余放电时间内,将当前车辆的车速调整至预设的最低安全车速。由此,解决了在无法获取蓄电池电量时,因不限制车速或车速限制不当导致车辆动力丢失的问题,避免蓄电池的电量过低,为用户的行车安全提供保证,减少交通事故的发生。
