AI Technical Summary

Problems solved by technology

[0006] 1. With more and more types of power loss and beyond the conventional cognition, technicians and maintenance personnel often spend a long time learning and dealing with a problem from analysis to processing
[0007] 2. The handling of the power loss problem is from finding the problem to analyzing the problem and then solving the problem. The technicians and maintenance personnel are often in a passive and late-knowing position, and the fault is usually offline after the power loss occurs. Fundamentally, the reason for positioning has brought great troubles, and at the same time increased user complaints, brought great troubles to customers, and had a very bad impact on corporate reputation

Embodiment Construction

[0029] Embodiments of the invention will be described in detail below with reference to the drawings.

[0030] The general idea of ​​the present invention is: use big data to extract background data of networked vehicle models, the data content mainly includes data reflecting the working state of the vehicle such as voltage, power, accumulated discharge, power status, door lock, etc. Algorithms such as abnormal wake-up and accumulated power consumption are used to classify and summarize the data. For vehicles with dormancy or abnormal wake-up problems, use the wake-up source log system to perform positioning judgments. If it is difficult to locate, you need to analyze on-site objects; for vehicles with dark current exceeding the normal value or in low voltage problems, contact terminal colleagues or return visits to users Deal with it; and the above problems are tracked by forming a power deficit problem tracking table.

[0031] Such as figure 1 As shown, the vehicle power l...

Abstract

The invention discloses a vehicle power shortage early warning method, which comprises the following steps: extracting networked vehicle type background data by using big data, classifying and concluding the data, carrying out positioning judgment on a vehicle with a dormancy or abnormal wakeup problem by using a wakeup source log system, and carrying out in-place and in-place analysis on a vehicle which is difficult to position; for a vehicle with dark current exceeding a normal value or in a low-voltage problem, contracting a terminal for colleague or visiting back a user for processing; and enabling all the problems to form an undervoltage problem tracking table for tracking. According to the invention, the big data is utilized to actively find the abnormal power-lack vehicle and analyze the reason, the power-lack complaint rate of the user is effectively reduced, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle electrical systems. Background technique [0002] With the development of automobile electrification and intelligence, automobile functions are more and more complex, and automobile electronic control units and software logic strategies are also increasing. The coupling degree of electronic control units is also getting higher and higher. The probability of electricity also deepens. [0003] Due to the increase of vehicle electrification and the increase of software volume, a small software bug in the vehicle, coupling errors between systems, quality problems of parts, etc., may lead to power loss of the vehicle, which will bring extreme inconvenience to users. A good influence has a very bad influence on the company's reputation. [0004] The traditional power loss processing mode is to locate the cause by confirming the battery voltage of the vehicle, user usage, and on-site use of bus equipme...
