Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to automatic testing equipment for a vehicle-mounted navigation controller. Background Art

[0002] With the development and construction of cities, the road environment has become increasingly complex. In-vehicle navigation has become an essential tool for travel and also the focus of information system testing. The in-vehicle navigation controller is the core component of the in-vehicle navigation system, responsible for receiving and processing various navigation information to achieve functions such as vehicle positioning, route planning, and navigation prompts.

[0003] Traditional vehicle navigation controller testing includes hardware testing and data testing. Hardware testing mostly uses manual inspection of the specifications, models and welding positions of internal components, followed by power-on debugging, but lacks interface stability testing. At the same time, most of the data testing is verified through actual vehicle travel, such as testing the positioning accuracy of the navigation controller, the accuracy and update frequency of map data, and path planning algorithm testing. However, this method takes into account factors such as cities, roads, working conditions, and bad weather, and requires a lot of manpower and material resources. The testing process is cumbersome and the operation is extremely inconvenient. At the same time, when facing different vehicle navigation systems, the above work needs to be repeated for testing, which causes huge manpower and material costs and cannot meet usage needs.
