The invention discloses a vehicle braking performance early warning method and device, and belongs to the technical field of vehicles. According to one specific embodiment, the method comprises the steps that historical braking data of a current vehicle in a preset time period and the real-time vehicle speed and real-time braking force of the current vehicle are obtained, and a first predicted value of the braking distance corresponding to the current vehicle is calculated according to the historical braking data, the real-time vehicle speed and the real-time braking force; acquiring a real-time braking distance of the current vehicle, and calculating a first difference value between the real-time braking distance and the first predicted value; determining whether the first difference value exceeds a first threshold value; and under the condition that the first difference value exceeds the first threshold value, a braking performance early warning prompt is generated. According to the implementation mode, panic psychology caused by reduction of the braking performance to a user is avoided, and even unnecessary accidents are avoided; and meanwhile, the situation that the vehicle using cost is high due to the fact that a user frequently maintains or replaces a brake component is avoided.
本发明公开了一种车辆制动性能预警方法及装置,属于车辆技术领域。该方法的一具体实施方式包括:获取当前车辆预设时间段的历史制动数据以及所述当前车辆的实时车速和实时制动力,并根据所述历史制动数据、所述实时车速以及所述实时制动力,计算所述当前车辆对应的制动距离的第一预测值;获取所述当前车辆的实时制动距离,并计算所述实时制动距离和所述第一预测值之间的第一差值;确定所述第一差值是否超过第一阈值;在所述第一差值超过所述第一阈值的情况下,生成制动性能预警提示。该实施方式避免了制动性能下降给用户造成恐慌心理,甚至避免了不必要的事故;同时也避免了用户频繁保养或更换制动部件造成用车成本较高的情况。
