Automatic parking method, electronic equipment and automobile

Abstract

The invention discloses an automatic parking method, electronic equipment and an automobile. The automatic parking method comprises the steps of recognizing a roadside parking space, which satisfies an automobile body specification and is positioned on one side of a curb, on the basis of a first sensor; judging whether there is an obstacle affecting automobile door opening on the curb or not on the basis of a second sensor independent of the first sensor; and if the obstacle exists and the obstacle affects the automobile door opening, planning a trajectory with maximum automobile door openingand no interference of the obstacle as reference and automatically parking an automobile. According to the automatic parking method, the electronic equipment and the automobile, on the basis of multi-sensor data fusion full-automatic parking scheme, a problem that a user cannot open an automobile door after an automatic parking system finishing parking is successfully solved through system intelligent calculating and processing during processing the limited parking space type. According to the automatic parking method, by optimizing a special parking space logic strategy, the scene coverage rate of an automatic parking technology is increased, user complaints can be reduced, and the user experience feeling can be greatly improved.

Description

technical field [0001] The invention relates to the technical field related to automobiles, in particular to an automatic parking method, electronic equipment and automobiles. Background technique [0002] At present, the existing automatic parking technology is basically based on ultrasonic or image-based automatic parking system. Since the camera is seriously affected by the weather such as light, coupled with factors such as cost and technical bottlenecks, there are many solutions based on ultrasonic. However, due to the characteristics of the ultrasonic wave itself, the detection range, blind spots and other defects, for special scenarios, such as approaching the parking space on the roadside (there is a similar stone pier roadblock next to the roadside), the automatic parking system can identify the obstacle vehicle and the roadside, according to the current situation In some strategies, the posture of automatic parking will be based on a certain distance from the roads...

Problems solved by technology

However, due to the characteristics of the ultrasonic wave itself, the detection range, blind spots and other defects, for special scenarios, such as approaching the parking space on the roadside (there is a similar stone pier roadblock next to the roadside), the automatic parking system can identify the obstacle vehicle and the roadside, according to the current situation In some strategies, the posture of automatic parking will be based on a certain distance from the roadside (usually 30cm), but in real scenes such as square roadsides, there will be facilities similar to stone piers. After parking with the automatic parking system alone, there may be The door cannot be opened, reducing user satisfaction

[0003] like figure 2 , the existing automatic parking system based on ultrasonic radar, due to the bottleneck of the detection distance of the ultrasonic probe (at present, the detection distance of the ultrasonic probe is basically ≤ 5m) can identify the obstacle vehicle 23 and the roadside 21, but cannot detect obstacles similar to stone pier 22. When encountering such a parking space scene with a roadside, according to the scene analysis system, the roadside will be given priority as the basis for parking attitude. At present, the parameters of the parking system are basically calibrated based on 30cm (detection error ± 10cm) close to the roadside. After parking image 3 As shown, for the above scenario, there is a risk that the door cannot be opened after parking
