Embodiment Construction

[0024] Below, the present invention will be further described in combination with preferred numerical settings and specific implementation methods; all preferred numerical values ​​are only used as the best implementation mode, and are not used to limit the scope of protection of the claims.

[0025] Firstly, the pre-judgment and monitoring steps are used to preliminarily predict the state of the car. The state of the car includes the start state and the flameout state. Use ADC (Analog to Digital Converter) to monitor the voltage of the car battery, use the vibration sensor to monitor the car vibration to obtain vibration signals, use GPS to monitor the speed of the car, and use OBD (On Board Diagnostic System) to monitor the engine speed. When ODB fails to obtain the engine speed, it will return failure.

[0026] The judgment method for the startup state is as follows: Situation 1. Read the ADC value every 3 seconds and save it as the ADC basic value x. When the ADC basic val...

Abstract

The invention discloses an automobile state judging method. The automobile state judging method comprises a circular pre-judging and monitoring step and a correcting step. Through the circulation monitoring of the skipping judging and supplement testing mechanism, the automobile state which is mistakenly judged / or skipped can be corrected back to the real automobile state at any abnormal situation. In particular, after being electrified for the first time and after abnormal restart, the defects in the prior art are changed. It is guaranteed that whether the stored automobile state is consistent with the real automobile state or not can be corrected in time. The control system can accurately judge the automobile state, and the overall safety can be effectively improved.

Description

technical field [0001] The invention relates to a method for judging the state of a car, in particular to a method for judging the state of a car and self-correcting the judging state. Background technique [0002] With the wide application of OBD (On-Board Diagnostic), the judgment of vehicle state is very critical to the control system of the whole vehicle, and the vehicle state includes starting, flameout, motion and other states. The two states of starting and flameout both have the real state and the detection state recorded by the control system or judged according to other parameters. When the real state is consistent with the detected state, the car is under the correct monitoring control of the control system; when the real state is inconsistent with the detected state, the car is under the wrong control of the control system. When the control system wrongly monitors the state of the car, it may cause serious traffic safety problems. For example, when the control ...
