Embodiment Construction

[0040] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0041] The embodiment of the present invention aims at the inability to automatically control the on-off of the electronic control unit and the electrical appliances of the whole vehicle during the function test of the existing electric vehicle, as well as the inability to realize the simulation test, and provides an electric vehicle function test system, which improves the test performance. Efficiency, to achieve precise control of signal input and output.

[0042] Such as figure 1 As shown, the electric vehicle function test system of the embodiment of the present invention includes:

[0043] Host computer 1;

[0044] The first controller area network CAN communication module 2 and the hardware-in-the-loop simulation HIL signal output module 3 respec...

Abstract

The invention provides an electric vehicle function test system, which relates to the technical field of electric vehicle production test. The electric vehicle function test system includes a principal computer, a first CAN communication module and an HIL signal output module which are connected with the principal computer, and a BOB controller which is connected with the first CAN communication module and the HIL signal output module. The BOB controller is further connected with an electronic control unit and a vehicle electrical appliance of an electric vehicle under test. The principal computer is used for outputting a gating control signal to the BOB controller through the first CAN communication module and outputting an HIL signal to the BOB controller through the HIL signal output module. The BOB controller is used for controlling the connection or disconnection between the vehicle electrical appliance and the electronic control unit and the connection or disconnection between the vehicle electrical appliance and the HIL signal output module according to the gating control signal. Through the scheme of the invention, the function of electric vehicles can be automatically tested, and the test efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle production test, and in particular relates to an electric vehicle function test system. Background technique [0002] In the test and development process of electric vehicles, the real vehicle function test is a very important task. Regardless of the traditional gasoline vehicle or the pure electric vehicle, the real vehicle function test is applied to the whole vehicle development as a must. [0003] In the prior art, when testing the functions of the real vehicle, the signal on and off between the electronic control unit and the electrical appliances of the whole vehicle is mainly controlled manually, and automatic control cannot be realized, and the moment of connection and disconnection of the two cannot be detected. The output signal of the electronic control unit cannot be simulated and tested. Contents of the invention [0004] The purpose of the embodiments of the present inven...
