The embodiment of the invention provides an early warning method and device for braking performance. The method comprises the steps that driving data collected during braking in the automatic driving process of a vehicle is obtained; determining a current braking scene, and judging whether the driving data triggers an early warning condition for braking performance or not according to the current braking scene; and under the condition that the vehicle triggers the early warning condition for the braking performance, a first early warning message for the braking performance is generated. According to the embodiment of the invention, the early warning of the brake performance is realized according to the driving data of the vehicle brake, on one hand, the method can adapt to brake modules of different vehicle types, different structures and different materials, on the other hand, the set thickness threshold does not need to be reached, the early warning of the whole process of the brake performance change can be realized, and the sensitivity is high; and different early warning strategies are adopted according to the braking scene, so that the method can be adaptive to conditions beyond conventional braking.
本发明实施例提供了一种制动性能的预警方法和装置,所述方法包括:获取在车辆自动驾驶的过程中进行制动时采集的行驶数据;确定当前制动场景,并根据所述当前制动场景,判断所述行驶数据是否触发针对制动性能的预警条件;在所述车辆触发针对制动性能的预警条件的情况下,生成针对制动性能的第一预警消息。通过本发明实施例,实现根据车辆制动的行驶数据进行制动性能的预警,一方面能够适应不同车型、不同结构、不同材料的刹车模块,另一方面无需达到所设定的厚度阈值,能够对制动性能变化的全过程进行预警,灵敏度较高,而且,通过根据制动场景采用不同的预警策略,能够自适应超出常规制动之外的情况。
