The invention provides an automobile starting load detection method, and the method comprises the following steps: in the ignition starting process of an automobile, collecting voltage information ofa vehicle-mounted automatic diagnosis system through a high-frequency analog-to-digital converter; obtaining the minimum voltage in the ignition starting process of the automobile according to the voltage information; acquiring health state information of an automobile storage battery according to the minimum voltage, and outputting the health state information; or acquiring the rising time of theautomobile from the minimum voltage to the working voltage; acquiring health state information of the automobile storage battery according to the rising time, and outputting the health state information. The problems that in the prior art, when the capacity of the automobile storage battery is detected, a one-time data collection mode is adopted, the detection accuracy is poor, and aging of the storage battery cannot be found in time are solved.
本发明提供一种汽车启动负荷的检测方法,包括:在汽车点火启动过程中,通过高频模数转换器采集车载自动诊断系统的电压信息;根据所述电压信息获取汽车点火启动过程中的最小电压;根据所述最小电压获取汽车蓄电池的健康状态信息,并输出所述健康状态信息;或者获取汽车从所述最小电压上升到工作电压的回升时间;根据所述回升时间获取汽车蓄电池的健康状态信息,并输出所述健康状态信息。本发明解决了现有技术在检测汽车蓄电池容量时采用一次过的数据采集方式存在的检测准确度欠佳、无法及时发现蓄电池老化的问题。
