Description

Simple advanced intelligent auxiliary driving system detection system and method

Technical Field

The present disclosure relates generally to the field of advanced driver assistance device detection, and more particularly, to a simple advanced intelligent driver assistance system detection system and method.

Background

The ADAS system is an important component for assisting driving, is the basis of AEBS and LKA, and is also the most basic information source for unmanned driving. The ADAS comprises a plurality of sensors, and in China, the requirements of regulations such as 883 and 1242 are generally higher than those of Europe, so that the method of fusing a camera and a millimeter wave radar is mainly adopted for the sensor of the ADAS. Specifically speaking: the camera identifies lane lines and pedestrians. The 77G millimeter wave radar recognizes strongly reflecting objects of the radar, such as vehicles, bridges, and the like. The two are fused and corrected, so that the recognition efficiency can be improved, the false alarm is reduced, and effective judgment is carried out on pedestrians, old mobility scooter, curves, rotary islands, tunnels and the like.

After the ADAS, the AEBS and the LKA are assembled from the automobile factory, the working state of the equipment is difficult to judge when the automobile is delivered to the hands of a user. Particularly, AEBS and LKA are low-frequency conditions, and usually are triggered twice a year, so that whether the AEBS and the LKA are illegally turned off or fail is determined, and both users and a vehicle manufacturer can not determine the AEBS and the LKA. If the vehicle needs to be checked, the vehicle needs to be driven to a closed test site, the model vehicle and the model person are moved from a far place to a near place, and whether the equipment works normally is confirmed according to the alarm state. The existing testing method has the following defects: a large test field is needed, on one hand, a test vehicle needs to be started to accelerate to reach a penalty speed of 60km/h, and on the other hand, a model vehicle and a model person need a certain moving space, so that the test field can be more than one kilometer; a professional driver is needed, when equipment fails, the equipment is considered to be braked, the tested vehicle is prevented from being loaded with a model vehicle or a model person, and the requirement on the driving skill of the driver is high; the test time is long, and from the installation of a model car and a model person to repeated multiple measurements, one sufficient test can be one day or more; and the collision risk can have serious consequences when the test measuring vehicle collides with the model vehicle and the model person.

In summary, the prior art cannot realize large-scale verification after ADAS loading.

In view of the above, the present invention and embodiments thereof are set forth below.
