Problems solved by technology

However, the current parking assistance system lacks the fault monitoring of the radar probe. Once the radar probe fails, it will cause misjudgment by the driver and easily lead to collision accidents.
In addition, the radar probe of the existing parking assistance system is only installed at the rear of the car, and when reversing or moving the car, the car is relatively close to the surrounding obstacles, and the driver's viewing angle is limited, which often leads to the front of the car. Bump into a corner or low obstacle
The existing parking assistance system is only triggered by the reverse gear signal, and the control is not reasonable enough

Abstract

The invention provides a parking assisting system with comprehensive function and a control method thereof. The parking assisting system is used for assisting a driver to park safely. The system comprises a control unit and a gear sensor, a loudspeaker, a display and radar probes which are respectively connected with the control unit. The system is characterized in that a plurality of radar probes are respectively installed on the bumpers in the front and rear parts of a vehicle. In order to control the radar probes installed on the bumpers in the front of the vehicle conveniently, the control unit is further connected with a vehicle speed sensor. In the invention, the radar probes installed on the bumpers in the front of the vehicle are added so as to reduce the visual dead angle of the driver and help the driver park and transfer in narrow space. The parking assisting system further adds a self-examination step to the radar probes so as to avoid the situation that the radar probes break down but the driver does not know, thereby improving the safety of parking. The parking assisting system is triggered by means of a reverse gear signal and a vehicle speed signal, therefore, the control method is more reasonable and effective.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and in particular relates to an automobile parking assistance system and a control method thereof. Background technique [0002] The car's parking assistance system mainly includes a radar control module and a radar probe installed at the rear of the car, which are used to assist the driver in parking, remind the driver of the distance between the car and the obstacles behind, and prevent the car from colliding with obstacles in the blind spot of the driver's observation. Reduce the incidence of accidents and ensure personal safety. However, the current parking assistance system lacks fault monitoring for radar probes. Once the radar probe fails, it will cause misjudgment by the driver and easily lead to collision accidents. In addition, the radar probe of the existing parking assistance system is only installed at the rear of the car, and when reversing or moving the car, the car...
