It is impossible to independently detect and identify the battery system structure, and the signal from the collision sensor basically means that the vehicle must be maintained and repaired. When an operating vehicle scrapes the bottom of the vehicle and continues to operate without effective identification, but its structure is damaged, it will cause the internal battery cells to be squeezed and stressed, the risk of battery system loss of control increases, and timely alarms cannot be issued.

[0027] The present disclosure is further described below in conjunction with the accompanying drawings and embodiments.

[0028] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present disclosure. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present disclosure belongs.

[0029] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0030] Example 1

[0031] In one embodiment of the present disclosure, a vehicle battery system structural safety detection method is provided, comprising:

[0032] Obtain basic vehicle data, set key deviation thresholds, obtain actual vehicle operation data, and transmit the actual operation data to the vehicle VCU for processing. Use the key deviation thresholds to compare with the actual operation data, and transmit the processing structure to the user end. The user end establishes communication with the maintenance client. The maintenance client obtains the vehicle's maintenance inspection data. When no fault is detected, the key deviation threshold of the safety inspection is updated, and it is confirmed whether the safety inspection strategy needs to be upgraded. If no upgrade is required, the vehicle continues to operate.

[0033] Among them, the key data obtained based on the simulated road conditions carried out by the sensors installed on the whole vehicle before the vehicle is first put on the market is used as the basic data of the strategy. The strategy is formulated based on the obtained data and whether there is a fault in the battery system to determine whether a fault occurs.

[0034] Then determine whether an upgrade is needed, including:

[0035] A) For structural safety failures that are not identified on the market side, the sensor detection data is retrieved through the background to formulate and improve strategies and perform upgrades.

[0036] B) Based on the supplementary road condition data from the test department, new fault conditions are identified, and strategies are improved and upgraded.

[0037] If an upgrade is required, the updated critical deviation threshold will be updated to the entire vehicle VCU.

[0038] As an embodiment, the actual operation data includes power battery system data, vehicle vibration frequency and vibration amplitude. The present disclosure adds a power battery system data detection sensor (the quantity can be defined by oneself) to the power battery system or its part in the vehicle, and installs it at a certain position in the power battery system to be detected (generally placed inside the power battery system), which can be defined by oneself. The reference (vehicle) sensor is generally placed at the center of the vehicle chassis close to the interior of the car or at a position that the vehicle manufacturer considers more suitable), so as to monitor the vibration frequency, vibration amplitude and force position of the vehicle power battery system and the whole vehicle, and determine the degree of risk at the position by comparing the data at different positions with the deviation of the reference sensor of the whole vehicle.

[0039] After the power battery system data detection sensor and the reference (vehicle) sensor obtain the vibration frequency, vibration amplitude, force position and other data of the vehicle power battery system and the whole vehicle, they transmit the actual operation data of the vehicle to the whole vehicle VCU for processing through wiring harness or wireless connection and use information interaction strategy, and then transmit it to the background database for storage. Among them, the information interaction strategy refers to the vehicle controller (VCU) obtaining the signal sent by the sensor and guiding the vehicle to issue an alarm according to the established strategy.

[0040] The sensors described above communicate through wiring harnesses or wireless as information transmission media, and transmit the detected data to the corresponding management system, vehicle controller and user terminal (such as mobile phones, electronic watches, etc.). After the vehicle VCU receives the actual vehicle operation data, the vehicle VCU detects the vibration frequency and vibration amplitude of the vehicle during relevant test processes (including but not limited to simulations of various road conditions and extreme road conditions, simulations of fault conditions such as scraping and collisions, etc.), observes the change data and curves of the data, and statistically analyzes the test frequencies and vibration amplitudes of normal and specific fault simulations obtained from various tests, defines the vibration frequency difference boundary and the vibration boundary difference boundary, and thereby specifies the policy threshold of the risk level of the system.

[0041] The vehicle VCU transmits information about the detected risk level to the vehicle end (mobile phone APP, electronic watch, vehicle center console, vehicle big data center, etc.). Users or car companies can consider conducting vehicle inspections during maintenance or immediately go to auto repair centers or other places with inspection capabilities based on the received risk level and risk area, and upload the inspection results to the maintenance client to determine whether the risk fault affects the safe use of the vehicle.

[0042] As an embodiment, the user can cancel the prompt of the corresponding risk level by controlling the vehicle through a mobile phone or central control to avoid being disturbed, but the corresponding detection data will be recorded and transmitted in real time.

[0043] As an embodiment, a vehicle equipped with sensors undergoes a road condition test to obtain a large amount of data. Automobile manufacturers can obtain relevant key data of the sensors (vibration frequency, vibration amplitude and its position) through road condition tests or other relevant equivalent tests to realize analysis of the safety status detection of key components of the whole vehicle. Experts formulate key deviation thresholds of safety detection strategies based on test data and upload them to the whole vehicle VCU (or this component management system), transmit actual operation data to the whole vehicle VCU for processing, compare the key deviation thresholds with the actual operation data, and transmit the processing results to the user end; the user end establishes communication with the maintenance client, and the maintenance client obtains the vehicle's maintenance inspection data. When no fault occurs, the key deviation threshold of safety detection is updated, and it is confirmed whether the safety detection strategy needs to be upgraded. If no upgrade is required, the vehicle continues to run; if an upgrade is required, the updated key deviation threshold is upgraded to the whole vehicle VCU.

[0044] The vehicle controller and its component management system use the data obtained to analyze the safety status of key vehicle components based on the system strategy updated in the vehicle background or the analysis strategy that the vehicle has been equipped with. The data is transmitted to the central control, mobile phone and other terminal display devices, and the big data center of the car company through wiring harnesses or wireless connections. Users can cancel the corresponding risk level prompts for vehicle control through mobile phones or central control to avoid being disturbed. However, the corresponding detection data will be recorded and transmitted in real time.

When no fault occurs, the key deviation threshold of the safety inspection is updated, and it is confirmed whether the safety inspection strategy needs to be upgraded. If no upgrade is required, the vehicle continues to operate;
