Embodiment 1

[0051] An automatic parking device is provided in an embodiment of the present invention, such as figure 1 As shown, the device includes: an environmental information collection module, a collision risk calculation module, a route planning module and a control module.

[0052] The environmental information collection module is used to collect surrounding environmental information as an aid to route planning and a basis for obstacle detection. like figure 2 As shown, the environmental information collection module includes an image collection unit and an ultrasonic detection unit, the image collection unit is used to collect image information, and the ultrasonic detection unit is used to detect the distance between surrounding objects and the vehicle. The image acquisition unit is a camera. During the process of automatic parking, the environment information collection module collects the environment information around the vehicle in real time. The environmental information...

Embodiment 2

[0069] An automatic parking method is provided in an embodiment of the present invention. like Image 6 As shown, the automatic parking method includes:

[0070] S1. Search for vacant parking spaces and plan driving routes, prompting drivers to stop;

[0071] S2. Obtain an automatic parking start signal, and control the vehicle to perform an automatic parking operation;

[0072] S3. Detect whether there is an obstacle on the driving route, and detect whether a collision between the vehicle and the obstacle may occur;

[0073] S4. When obstacles are continuously detected, re-plan the driving route;

[0074] S5. Control the vehicle to perform an automatic parking operation until the vehicle enters the target parking space.

[0075] Further, when there are obstacles on the replanned driving route, the braking and route planning are repeated until the parking operation is completed.

[0076] Further, after the vehicle is parked in the target parking space, it is detected whet...

Embodiment 3

[0083] An embodiment of the present invention provides an emergency braking method in which obstacles exist on the driving route during automatic parking, such as Figure 7 As shown, the method is as follows:

[0084] S01. During the parking process, detect the surrounding environment of the vehicle in real time;

[0085] S02. Locate the detected obstacle and determine the type of obstacle;

[0086] S03. Determine whether the obstacle is located on the driving route, and determine whether there is a risk of collision;

[0087] S04. When there is a risk of collision, brake the vehicle until the vehicle stops.

[0088] Specifically, during the automatic parking operation, the control module comprehensively controls the steering wheel, electronic shifter, accelerator pedal, brake pedal, etc. according to the driving route planned by the route planning module to steer and move the vehicle, and controls the driving of the vehicle. into the parking space. When the vehicle enters...

Abstract

The invention relates to the field of intelligent drive and provides an automatic parking device and method. The automatic parking device comprises an environment information collection module, a route planning module, an impact risk accumulation module and a control module. The control module comprises a steering control unit, a braking unit, an electronic brake control unit and a gear control unit. The automatic parking device can lastinglydetect surroundings when parking begins to be carried out on a scheduled driving route after planning; when obstacles suddenly appear on the driving route, an impact risk can be judged, and emergency braking is carried out on a vehicle when the impact risk is high. Meanwhile, the automatic parking device can re-plan the driving route after the emergency braking and obstacles are avoided. According to the automatic parking device and method, when the obstacles appear on the scheduled driving route and the impact risk is high, the vehicle can be controlled to have the emergency braking, and therefore safety of the vehicle and user experience are improved.

Description

technical field [0001] The invention relates to the field of intelligent driving, in particular to an automatic parking device and method. Background technique [0002] As a means of transportation, vehicles are receiving continuous attention now that road traffic is becoming more and more developed and urban areas are getting larger and larger. Various technologies applied to vehicles are also advancing with the times, and driver assistance control technology is one of them. Driving assistance control technology can assist or replace the driver to control the vehicle in specific scenarios, improving the comfort of the vehicle. [0003] Automatic parking control technology is one of the most commonly used driving assistance control technologies on vehicles at present. It measures the distance and angle between the vehicle and surrounding obstacles through ultrasonic probes spread around the vehicle body, and then calculates the distance and angle of the vehicle through the ...
