Abstract

The invention discloses a virtual fault injection test method based on power supply control. The idea of ​​the invention is to realize real control and real control through the combination of multiple pre-built simulation models without changing the vehicle network topology and communication physical medium. The virtual control switches in an orderly manner at any time, and under the virtual fault injection, the safety protection strategy of each vehicle system is verified, so that possible design defects can be found in time. When the system runs to any working state, the present invention can flexibly cover all the signals sent by all the controllers of the vehicle and various fault modes of the signals at any time. Fault injection, rather than a specific working state, shows that the present invention greatly improves the coverage of vehicle test verification, and can easily reach the test conditions and enter the test conditions, thereby significantly improving the test efficiency.

Description

technical field [0001] The present invention relates to the technical field of vehicle testing, in particular to a virtual fault injection testing method based on power supply control. Background technique [0002] With the development of automobile intelligence, more and more on-board controllers are applied to the car, and various controllers exchange data through the bus to form a network communication topology. In the development and verification of the on-board controller, each controller is connected to the network according to this topology, and then the joint test and verification are carried out. However, such methods cannot flexibly cover all types of signals and signal faults at any time. Specifically, in the prior art, a virtual simulation controller can be added to the existing bus topology. Under normal circumstances, the real controller is mainly used for network communication interaction. In the above test scenario, when fault injection is performed, it can ...
