The invention provides a leakage diagnosis method and device, a vehicle, a storage medium and a computer program product. The leakage diagnosis method comprises the following steps: in response to a current flameout event of the vehicle, starting a leakage diagnosis module of the vehicle; under the condition that an electromagnetic valve of the leakage diagnosis module is located at the diagnosis position, diagnosis current of the leakage diagnosis module is obtained, and the current estimated leakage aperture of the vehicle is determined based on the diagnosis current; and under the condition that the current estimated leakage hole diameter exceeds a first hole diameter threshold value, it is determined that leakage exists in the fuel system of the vehicle at present. According to the leakage diagnosis method, the estimated leakage aperture of the vehicle is determined through the diagnosis current of the leakage diagnosis module, and the fuel leakage condition of the vehicle fuel system can be effectively judged.

    本公开提供了一种泄漏诊断方法及装置、车辆、存储介质、计算机程序产品。所述泄漏诊断方法包括:响应于所述车辆当前的熄火事件,启动所述车辆的泄漏诊断模块;在所述泄漏诊断模块的电磁阀处于诊断位置的情况下,获取所述泄漏诊断模块的诊断电流,并基于所述诊断电流确定所述车辆当前的预估泄漏孔径;在当前的所述预估泄漏孔径超过第一孔径阈值的情况下,确定当前所述车辆的燃油系统存在泄漏。本公开提出的泄漏诊断方法通过泄漏诊断模块的诊断电流确定车辆的预估泄漏孔径,能够有效判别车辆燃油系统的燃油泄漏情况。
