Embodiment Construction

[0019] In order to fully understand the technical content of the present invention, the technical solutions of the present invention will be further introduced and illustrated below in conjunction with specific examples, but not limited thereto.

[0020] like figure 1 In the specific embodiment shown, a method for detecting vehicle startup in the present invention includes the following steps:

[0021] Step 1: The detection device is awakened during normal sleep, and the AD sampling module starts to detect the sampled voltage value, and judges whether the voltage value is higher than the preset value; if it is not higher than the preset value, enter the next step, if it is higher If it is at the default value, go to step 5;

[0022] Step 2, the AD sampling module starts to detect the sampling voltage value of its cache, and judges whether the sampling voltage value has a voltage fluctuation within a preset time; if there is no voltage fluctuation, enter the next step, if ther...

Abstract

The invention relates to a method and a system for detecting the starting of a vehicle. The method comprises the steps of 1, detecting a voltage value by an AD sampling module and judging whether the detected voltage value is higher than a preset value or not; if yes, conducting the next step; otherwise, conducting the step 5; 2, detecting the voltage value cached by the AD sampling module and judging whether the voltage fluctuates or not; if not, conducting the next step; otherwise, conducting the step 5; 3, starting an electronic gyroscope to detect whether the vehicle has a continuous angle transition vibration wave or not; if no, conducting the next step; otherwise, conducting the step 5; 4, starting a GPS positioning module to detect whether the vehicle has a continuous speed change or not; if yes, conducting the step 5; otherwise, conducting the step 6; 5, starting the vehicle; 6, does not starting the vehicle. According to the technical scheme of the invention, different parameters of the vehicle are respectively detected by the AD sampling module, the electronic gyroscope and the GPS positioning module, and then whether the vehicle is started or not can be judged. The detection sensitivity and the detection accuracy are improved.

Description

technical field [0001] The present invention relates to a detection method, more specifically to a method and system for detecting vehicle startup. Background technique [0002] At present, China has entered the era of automobiles, and the common method for judging whether the vehicle has started is based on the voltage of the vehicle. Generally, the voltage of 13.5V is used as the threshold. If the voltage exceeds 13.5V, it is considered to be started, otherwise it is considered to be off. However, with more and more power modes of cars, the voltage difference caused by the newness and oldness of car batteries and other reasons, some hybrid cars or cars with too long battery life, when the car is started, the voltage cannot always be higher than a Fixed value, which makes this kind of smart terminal unable to accurately perceive whether the vehicle is started. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior ...
