Embodiment 1

[0060] This embodiment discloses a method for remote assessment of the health status of a new energy vehicle, including:

[0061] S100. The vehicle-mounted terminal obtains the fault code data and vehicle condition data of the new energy vehicle, and uploads them to the cloud platform through the T-box.

[0062] Specifically, the new energy vehicle fault code data and vehicle condition data are obtained through the on-board computer and on-board diagnostic system.

[0063] S200. The cloud platform obtains the maintenance record data of new energy vehicles, and fuses them with vehicle fault code features and vehicle condition data features to generate fault health features, vehicle condition health features, and maintenance health features.

[0064] Specifically, the fault code characteristics of new energy vehicles include: first failure time interval, first failure mileage, average failure time interval, average failure mileage interval, cumulative number of failure occurrenc...

Embodiment 2

[0099] This embodiment discloses a remote evaluation system for the health status of new energy vehicles, including: a data acquisition module 1, a data cleaning module 2, a weight calculation module 3, and a health score calculation module 4; wherein:

[0100] Data acquisition module 1, acquires new energy vehicle fault code data, vehicle condition data, and vehicle maintenance record data, and fuses the data to generate fault health features, vehicle condition health features, and maintenance health features; specifically, new energy vehicles The fault code data and vehicle condition data are transmitted to the data acquisition module 1 through the on-board computer and the on-board diagnostic system.

[0101] Data cleaning module 2, for different feature types, adopts different rules to clean vehicle feature data; specifically for different feature data, adopts different cleaning rules, it is understandable that some feature data are time-dependent with vehicle health Relev...

Abstract

A new energy vehicle health condition remote evaluation method comprises the steps that a vehicle-mounted terminal obtains fault code data and vehicle condition data of a new energy vehicle and uploads the data to a cloud platform through a T-box; the cloud platform acquires maintenance record data of the new energy vehicle and fuses the maintenance record data with the vehicle fault code featuresand the vehicle condition data features to generate fault health features, vehicle condition health features and maintenance health features; data cleaning is performed on the fault health features,the vehicle condition health features and the maintenance health features; weight calculation is carried out on the features after data cleaning; and a health comprehensive score of the new energy vehicle is calculated according to the fault health features, the vehicle condition health features and the maintenance health after weight calculation. According to the method, the vehicle health condition can be remotely evaluated based on the vehicle big data and displayed to a driver in a numerical value scoring mode, multi-dimensional features are constructed through the algorithm, the vehicle health condition can be accurately evaluated, the weight is determined based on statistical distribution of the health features, and the importance of the features can be objectively and accurately recognized.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, in particular to a method and system for remote evaluation of the health status of new energy vehicles. Background technique [0002] Among the existing on-board equipment, the vehicle fault diagnosis system is already a relatively mature technology. Through the vehicle information acquisition module connected with the vehicle's internal electronic control unit, the detailed parameters of the vehicle's various control systems can be accurately obtained. On the vehicle end, the driver can see the vehicle's tire pressure, SOC, temperature, and fault code index data, but these data are used in isolation. The vehicle big data collected by Tbox has not yet been fully utilized for comprehensive evaluation , the vehicle's health status lacks the means to quantitatively distinguish it. [0003] Moreover, only when the vehicle has a problem or failure, the vehicle will provide users with limi...
