The invention relates to the field of vehicle diagnosis systems, in particular to a vehicle data acquisition method and device and a vehicle diagnosis system.The vehicle data acquisition method is characterized in that a wheel brake is mounted on each wheel and used for providing braking force; the braking parameter collecting module is used for collecting braking parameters of a wheel brake during braking, and the braking parameters comprise the vehicle speed, the braking pressure, the opening angle of a brake and the braking distance; the brake disc wear model generation module is used for generating a brake disc wear model based on the brake parameters of the brake disc using different kilometers; the wear evaluation module is used for obtaining the wear degree based on the brake disc wear model and the brake parameters of the current brake disc; and the prompting module is used for prompting a user to replace the corresponding brake disc when the wear degree exceeds a preset value. Therefore, replacement can be conveniently reminded, and driving is safer.

    本发明涉及车辆诊断系统领域,具体涉及一种车辆数据采集方法、装置及车辆诊断系统,车轮制动器安装在每个车轮上,用于提供制动力;制动参数采集模块,用于采集车轮制动器在制动时的制动参数,制动参数包括车速、制动压力、刹车器开度角度和制动距离;刹车盘磨损模型生成模块,用于基于使用不同公里数段的刹车盘的制动参数生成刹车盘磨损模型;磨损评估模块,用于基于刹车盘磨损模型和当前刹车盘的制动参数得到磨损程度;提示模块,用于当磨损程度超过预设值时提醒用户对对应刹车盘进行更换。从而可以方便提醒进行更换,以使得行驶更加安全。
