A platform-based vehicle t-box method, system, storage medium and application

Abstract

The invention discloses a platform vehicle-mounted T-BOX method and system, a storage medium and application. Function matching of different vehicle types is achieved through CAN Baud rate self-adaption, offline configuration, gateway allocation and software upgrading. According to the technical scheme, a platform T-BOX is universal for various vehicle types. Product management and control are optimized, and the problem that inventory parts are insufficient or detained is effectively avoided. Hardware is universal. A large amount of repeated hardware development and test cost is saved, and manpower and material resource investment is effectively reduced; the software adaptability is high, a large amount of development workload is reduced, the development period is shortened, and new product development can be rapidly adapted. A TSP platform address can be automatically switched, manual instruction issuing for switching is not needed. A service problem possibly existing in large-batch T-BOX switching of new gateways is avoided and workload of manual operation is reduced.

Description

technical field

[0001] The invention relates to the technical field of automobiles, in particular to a platform-based vehicle T-BOX method, system, storage medium and application. Background technique

[0002] Vehicle-mounted T-BOX is a vehicle-mounted terminal used in the Internet of Vehicles system to communicate with the background system to realize the vehicle information display and remote vehicle control functions of the mobile APP. The car networking system includes the car T-BOX, car networking service platform (TSP) and mobile phone APP.

[0003] At present, due to the different Internet of Vehicles functions and vehicle conditions (such as communication methods, CAN baud rates, etc.) Car condition and feature list, the software needs to be completely redeveloped. In order to distinguish T-BOX of different models, each model needs to develop T-BOX with its own special part drawing number, resulting in duplication of development work and waste of human resources. ...

Examples

Embodiment 1

[0073] In order to achieve the above purpose, this embodiment proposes a platform-based vehicle T-BOX method, which realizes the function matching of different models through CAN baud rate adaptation, offline configuration, gateway allocation and software upgrade. The method of this embodiment is adapted to Strong performance, reducing a lot of development workload, shortening the development cycle, and being able to quickly adapt to new product development.

[0074] Further, see figure 1 : specifically include the following steps:

[0075] S1. T-BOX has common hardware when it leaves the factory, and the factory software is divided into two parts, the public version software for basic functions and the adaptation part software for each model, the public version software includes the 4G module part, the software is larger, and the adaptation part software is smaller; When the T-BOX leaves the factory, burn the same version of the basic public version software, and save the ad...

Embodiment 2

[0117] In addition, to achieve the above purpose, see Figure 5 : The present invention also proposes a platform-based vehicle T-BOX system, including platform-based T-BOX, EOL equipment, public gateway, BCM / PEPS;

[0118] The factory version software is installed on the platform T-BOX, and the platform T-BOX communicates with the EOL equipment through CAN baud rate self-adaptation, and the EOL equipment identifies the vehicle type by writing VIN+configuration word, when identifying Upgrade the T-BOX after the model, and copy the software of each model on the upgraded T-BOX; the public gateway allocates the gateway IP of each model, and the platform T-BOX obtains the IP through the public gateway registration default gateway, and logs in the new IP After obtaining the diagnostic ECU list and self-learning BCM / PEPS through SK / SC, the vehicle can be put into storage.

[0119] It should be noted that the present invention is aimed at adapting systems for different vehicle condit...

Embodiment 3

[0122] In addition, in order to achieve the above object, the present invention provides a storage medium, on which a platformized vehicle-mounted T-BOX program is stored, and when the platformized vehicle-mounted T-BOX program is executed by a processor, the above-mentioned platform is realized Judgment steps of the vehicle-mounted T-BOX method.
