Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] The embodiment of the present invention provides a T-BOX test system, which is a T-BOX test system emphasizing on the realization of integration, systematization and automation. Among them, refer to figure 1 , the HIL system can simulate the working conditions of T-BOX in the actual vehicle under laboratory conditions, including the simulation of the vehicle's working conditions (vehicle speed, engine torque, driver's operation, etc.), external communic...

Abstract

The invention provides a T-BOX test system and method. A channel simulator simulates a signal transmission environment when a T-BOX carries out data transmission; a signaling tester simulates a communication link used when the T-BOX carries out data transmission; a navigation signal simulation system simulates a navigation signal output by a navigation device; and a real-time system carries out information interaction of hard wire signals and/or bus signals with the T-BOX, wherein the parts above can form a closed-loop simulation test environment with a service background of the T-BOX to testthe T-BOX. According to the provided T-BOX test system, the channel simulator and the signaling tester provide a signal transmission process close to reality for the T-BOX; the navigation signal simulation system provides the navigation information close to reality for the T-BOX; the real-time system provides an interaction environment close to real vehicles for the T-BOX; and the test system cantest function and performance of the T-BOX through the simulated real vehicle test environment.

Description

technical field [0001] The invention relates to the field of simulation testing, and more specifically, relates to a T-BOX testing system and method. Background technique [0002] The trend of automobile intelligence and IoT continues to deepen, and more and more automobile technologies are combined with mobile Internet, Internet of Things and wireless communication technologies to provide users with a richer driving experience. [0003] The telematics controller Telematics BOX (T-BOX for short) is responsible for the V2N (Vehicle ToNetwork) of the Internet of Vehicles. Before the T-BOX product goes on the market, T-BOX needs to be tested. However, the current test plan for T-BOX products is limited to the individual testing of a certain component of T-BOX when the product is offline or the design function of the T-BOX product during product development, and does not test the T-BOX product in a simulated real vehicle test environment. -Box test.
