Problems solved by technology

[0003] However, during the use of the vehicle, the vehicle condition gradually changes, and the ignition voltage will also change accordingly. However, the preset voltage threshold value is fixed and cannot reflect the current actual condition of the vehicle, resulting in increasingly inaccurate detection results. precise

Embodiment Construction

[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] see figure 1 , an embodiment of the vehicle start detection device of the present invention is proposed, the device is applied to vehicle equipment, including a historical data recording module, a voltage threshold determination module and a vehicle start detection module, wherein:

[0041] Historical data recording module: used to record the historical data of the ignition voltage when the vehicle starts.

[0042] Specifically, each time the vehicle is started, the historical data recording module acquires the current ignition voltage data and records it. When the vehicle is started multiple times, multiple ignition voltage data are recorded to form historical data of the ignition voltage.

[0043] Preferably, each time the vehicle is started, the historical data recording module acquires the ignition voltage...

Abstract

The invention discloses a vehicle starting detection apparatus and method. The apparatus comprises a historical data recording module, a voltage threshold determination module, and a vehicle starting detection module. The historical data recording module is used for recording historical data of an ignition voltage when a vehicle is started; the voltage threshold determination module is used for determining a voltage threshold value according to the historical data; and the vehicle starting detection module is used for detecting a current ignition voltage of the vehicle and determining whether the vehicle is started based on the ignition voltage and the voltage threshold value. Compared with the prior art with a set fixed voltage threshold value, the voltage threshold value in the apparatus and method changes dynamically with the change of the vehicle operation situation; and the dynamically changing voltage threshold value meets the actual situation of the vehicle well, so that the final detection result is accurate. Moreover, the voltage threshold value is determined comprehensively based on multiple data recorded lately and thus is close to the current actual situation of the vehicle well, thereby improving accuracy of the final detection result.

Description

technical field [0001] The invention relates to the technical field of vehicle equipment, in particular to a vehicle startup detection device and method. Background technique [0002] As an accessory device connected to the car, the on-board device expands the functions of the car and meets the various needs of users. Usually, some in-vehicle devices hope to be able to start automatically when the vehicle is started, so as to provide users with more intelligent and humanized services. At present, the solution for detecting the start of the vehicle generally pre-sets a voltage threshold value. When it is detected that the current ignition voltage is higher than the set voltage threshold value, it is determined that the ignition is successful and the vehicle is started. Otherwise, it is determined that the ignition has failed. Vehicle does not start. [0003] However, during the use of the vehicle, the vehicle condition gradually changes, and the ignition voltage will also c...
