The invention discloses a testing method, system and storage medium of an ultrasonic radar vehicle control strategy. The method includes: acquiring detection information of an ultrasonic radar installed on a vehicle to be tested; building a vehicle model and an environment model of the vehicle to be tested, and the vehicle The model is built according to the actual vehicle condition of the vehicle to be tested; based on the vehicle model, the vehicle information when the vehicle to be tested is in the environment model is obtained, and the ECU function of the vehicle to be tested is tested according to the vehicle information and the detection information of the ultrasonic radar to generate a control Decision-making information; send control decision-making information to the vehicle model for execution, so as to analyze the ECU function according to the execution result. This method tests the ultrasonic radar car control strategy based on the built vehicle model, the environment model and the detection information obtained by the real ultrasonic radar, which reduces the research and development cost, shortens the research and development cycle, and reduces the influence of the unpredictable factors of the real vehicle on the car control. And it solves the problem that the noise is difficult to add.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a method for testing an ultrasonic radar vehicle control strategy, a test system for an ultrasonic radar vehicle control strategy, and a computer-readable storage medium. Background technique [0002] At present, the test of the ultrasonic radar vehicle control strategy is to control the vehicle according to the simulated ultrasonic radar detection signal through wire control reformation, so as to realize the test according to the vehicle control results. However, the virtual detection signal obtained by establishing the ultrasonic radar model cannot simulate the real ultrasonic radar noise, and the radar processing algorithm cannot correctly process the real ultrasonic radar information, resulting in a large number of problems in the subsequent switching process of the real ultrasonic radar. In addition, as the executive body, the modified vehicle by wire is expensive in the pr...
