Problems solved by technology

Such an operation will make the entire test process an open loop, and some normal signals will also be changed, so the signals obtained by the RDF module are unreliable. At this time, the simulation test cannot simulate the state of the intelligent driving system under real faults, so it cannot Effectively verify the implementation of redundant functions

Embodiment 1

[0026] see figure 1 , the present embodiment is a model-in-the-loop testing method for redundant function simulation testing, comprising the following steps:

[0027] S1. Start simulation: With this method, before starting the redundancy function simulation test, it is necessary to draw up a reasonable simulation test overview for the redundant system, and then combine the corresponding bus protocol to build the simulation test step document. The test step document information is mainly divided into test conditions, observation interface, execution operation, input interface, block condition, passing condition, etc.

[0028] S2. Opening the interface of the middle layer: the opening of the interface of the middle layer is carried out in the algorithm model. Specifically, an in-out function model is added to the Changan L3 algorithm module, so as to disconnect the communication link between the signal and the RDF function module. And set a signal fault code to 10000, if the te...

Abstract

The invention relates to a simulation test method and system for intelligent driving redundant function development and a computer readable storage medium, and the method comprises the steps: opening a part of signal interfaces when intelligent driving simulation is carried out in a stage of inputting a main function signal and a CAN bus signal, and disconnecting a part of signals, and fault injection is carried out on the signals, and then the signals are accessed to an original simulation environment. And finally, comparing and verifying the result of the observation interface according to the expected result of the case, thereby testing whether the function logic of the redundant system meets the requirement or not. In this way, the expectation that most signals are not changed but only the signals injected into the faults are changed is achieved, the scene where the real faults occur is effectively simulated, the redundant function closed-loop test based on the model-in-loop is formed, the test credibility is improved, and the test efficiency is improved through an MIL automatic test method.

Description

technical field [0001] The invention is used in the field of intelligent driving vehicle simulation testing, and more specifically is a model-in-the-loop simulation testing method for intelligent driving redundant function development. Background technique [0002] Redundancy was first used as a technical term commonly used by aircraft. It refers to the safety backup of the electronic control system of the aircraft to prevent the sudden failure of one system to affect the normal operation of the aircraft and threaten the lives of passengers. In the same way, the implementation of intelligent driving cars today also requires the blessing of redundant functions. When the automotive intelligent driving system guarantees its own normal operation, its redundant control must be considered to ensure that in the event of a single control system failure, the redundant control system takes effect to ensure the safety of the vehicle and drivers. [0003] From the perspective of intell...
