Embodiment Construction

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0042] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the difference between components in a specific posture (as shown in the accompanying drawings). If the relative positional relationship, movement situation, etc. change, the directional indication will change accordingly.

[0043] In addition, the descriptions r...

Abstract

The invention discloses a vehicle error signal control method, comprising: acquiring a vehicle check signal in real time, and judging whether the vehicle check signal is within a preset range; if not,acquiring a recorded error identifier value, adding a first preset value based on the recorded error identifier value to obtain a current error identifier value, and recording the current error identifier value; if yes, acquiring a recorded error identifier value, subtracting the recording by a second preset value to obtain a current error identifier value, and recording the current error identifier value; judging whether the current error identifier value is greater than or equal to a preset upper limit; if yes, determining that the signal is abnormal and a vehicle is in failure state. The vehicle error signal control method has the advantages that false alarm due to vehicle signal fluctuation can be avoided and false alarm rate of a vehicle false alarm signal is decreased. The inventionalso provides a vehicle error signal control system and a storage medium.

Description

Technical field [0001] The present invention relates to the field of vehicle technology, in particular to a control system for vehicle error signals, a control method thereof, and a storage medium. Background technique [0002] With the advent of the information age, the vehicle industry has achieved leapfrog development. However, due to the large number of electrical components inside the vehicle and the high degree of electrification, the signal received by the vehicle is relatively large, causing the vehicle signal to fluctuate easily, causing faults and false alarms, and then affecting the normal driving of the vehicle. [0003] However, in the prior art, when a vehicle fails, it mainly relies on various inspection systems in the vehicle, such as: vehicle control ECU self-inspection verification, hard-wire signal verification received by the vehicle control ECU, and CAN sent by other ECUs After the signal verification and other modules verify the error, the error signal is dir...
