The invention provides a system for detecting the start and the flameout of an automobile, and the system comprises an automobile detection unit, wherein a detection interface of the detection unit is connected with a detection interface of an on-board diagnostics (OBD) II of the automobile or a dynamic induction mechanism; and signals of the detection interface or signals of the dynamic induction mechanism arranged on the automobile are detected by the automobile detection unit, so as to judge whether the automobile is started or not. In the invention, the detection system and method are adopted, so the detection of the start state of the automobile is guaranteed to be more accurate and more timely; and meanwhile, in the invention, the OBD II is adopted to be connected in parallel with a detection plug to be connected with the detection system, so the original line of the automobile is prevented from being reformed and the vehicle safety is fully guaranteed.
Description
technical field [0001] The invention relates to detection technology, and is especially designed for a system and a detection method for automobile startup detection. Background technique [0002] In the prior art, the method of detecting whether the car is started is that the detection system detects the ACC line of the ignition switch. If there is a signal on the ACC line, it proves that the car has started. If there is no signal, it proves that the car has not started. There is no power until the ACC position is reached. If the key is not in this position, there will be no signal output. In reality, it is possible that the key is not in the ignition position and the car is in the starting state. At this time, the traditional detection method cannot detect It is not possible to accurately report the status of the car until the car is started. Contents of the invention [0003] The invention provides a method for accurately detecting the start-up and flameout of a car, a...
