Embodiment 1

[0096] like figure 1 As shown, this embodiment provides a parallel parking space preemptive automatic parking, including:

[0097] Step 1. Receive a parking instruction and control the vehicle to move forward at a preset speed.

[0098] The preset vehicle speed is lower than 20km / h.

[0099] Step 2. Identify suitable empty parking spaces.

[0100] like figure 2 As shown, the four vertical corner points of the current undetermined parking space are the proximal left corner point Q1, the far left corner point Q2, the far right corner point Q3, and the proximal right corner point Q4; point e is the vehicle in the parking space in front of the current undetermined parking space point f is the left corner point of the front of the vehicle in the parking space behind the current undetermined parking space; Q1Q2 is the left boundary line of the parking space, Q3Q4 is the right boundary line of the parking space, Q2Q3 is the front boundary line of the parking space, and Q1Q4 is th...

Embodiment 2

[0196] like Figure 8 As shown, this embodiment provides a parallel parking space preemptive automatic parking device, including:

[0197] A processing module, and a side camera, a side long-range radar, a front short-range radar array, a rear short-range radar array, and a human-computer interaction module connected with the processing module;

[0198] The side camera is used to collect environmental images around the vehicle body;

[0199] The lateral long-distance radar is used to detect the depth of the parking space;

[0200] The front short-range radar array and the rear short-range radar array are used to collect obstacle distance information;

[0201] The processing module is used to process camera and radar data, identify parking spaces, identify obstacles, plan parking routes, and perform parking control;

[0202] The human-computer interaction module is used for inputting automatic parking instructions.

[0203] like Figure 9 As shown, the processing module in...

Abstract

The invention provides a pre-occupation type automatic parking method and device of a parallel parking space. The method comprises the steps: 1, receiving a parking instruction, and controlling a vehicle to move forwards at a preset speed; step 2, identifying an appropriate empty parking space; 3, after the proper empty parking space is detected, controlling the vehicle to continue to advance to the preset position; step 4, pre-occupying a parking space, wherein the pre-occupying of the parking space is planning and executing left steering advancing; and step 5, backing up and entering the parking space, including planning and executing backing up and entering the space. The success rate of automatic parking is improved.

Description

technical field [0001] The invention relates to the technical field of automatic parking, in particular to a parallel parking space preemptive automatic parking method and device. Background technique [0002] With the development of automatic parking sensor technology and the improvement of automatic parking software algorithms, automatic parking technology has become more and more mature. In the existing automatic parking technology, when the vehicle detects the garage, it needs to completely drive away from the detected parking space until it is parallel to the next parking space, and then perform automatic parking. After the car leaves the detected parking space, it may be seized by the following vehicle, resulting in the target parking route being blocked by the following vehicle, and automatic parking cannot be performed. [0003] Therefore, the prior art needs to be further improved. Contents of the invention [0004] The present invention provides a parallel park...
