Abstract

The invention relates to an automatic parking function real vehicle test system and test method. The automatic parking function real vehicle test system comprises a vehicle subsystem, an unmanned aerial vehicle subsystem and a data processing and display subsystem. The vehicle subsystem is used for acquiring and transmitting the vehicle attitude, parking place position and obstacle position data calculated by an automatic parking controller. The unmanned aerial vehicle subsystem carrying the image sensor is used for acquiring the real vehicle attitude, parking place position and obstacle position data. The data processing and display subsystem is used for displaying the real data of the vehicle, the parking place and the obstacle and the calculation data of the automatic parking controllerin real time and can process the data and give quantitative indictors. The automatic parking function real vehicle test system and test method are convenient to move and suitable for multiple conditions, the real vehicle and the real sensor are applied to perform functional verification, the automatic parking effect can be visually displayed and the automatic parking performance can be objectively evaluated by the data processing and analysis result.

Description

technical field [0001] The invention relates to the technical field of automobile automatic driving, in particular to the construction of a real vehicle test system for automatic parking functions and the design of a test method. Background technique [0002] In recent years, with the rapid development of artificial intelligence technology and sensor technology, intelligent driving hardware and algorithms have become research hotspots. More and more vehicle manufacturers, component manufacturers, and even Internet companies have invested relatively large manpower and material resources in intelligent driving. in the field. Automatic parking is a technology that is easy to commercialize in intelligent driving. Many manufacturers have launched automatic parking systems, but the market response is mediocre. Many customers complain that the automatic parking system is not practical, and the limitation of the test method restricts the automatic parking technology. One of the key...

Problems solved by technology

The software simulation test method of automatic parking is to build a virtual simulation environment by modeling the kinematics characteristics of the vehicle itself and the sensor characteristics installed on the body, and test the function of the automatic parking system in the virtual simulation environment, but the real vehicle motion The characteristics and sensor observation characteristics cannot be accurately modeled, so this method can only test and verify the correctness of the functional logic

The hardware-in-the-loop test method of automatic parking, by installing real sensors on the bench and using the moving bench to simulate the movement of the vehicle, tests and verifies the automatic parking system, but this method has two main shortcomings, the first , the bench can only be placed in a fixed experimental location, and it is not easy to move casually, which limits the test conditions. Second, the motion characteristics of the mobile bench are also quite different from those of real vehicles on the road, so it cannot be accurately evaluated Performance of automated parking systems

The vehicle-in-the-loop test method of automatic parking, by constructing a virtual test environment, generates sensor data according to the virtual environment, and sends the data to the real vehicle, and the vehicle completes the automatic parking function according to the virtual data. Although this method solves the problem of software simulation In the test method, the real vehicle model is not easy to establish, but there will be some errors in the modeling of the sensor model and the test environment, and the performance of the automatic parking system cannot be accurately evaluated.

For automatic parking system testing, the best solution is to use real sensors and real vehicles to test in a real multi-working environment, but there is currently no mobile test data acquisition and analysis system or device
