Description

Technical Field

[0001] The present invention belongs to the field of automobile technology, and more specifically, relates to a method and device for contactless control of automobile movement and a vehicle controller. Background Art

[0002] In life, due to irregular parking, other people's cars often block your car, making it impossible to drive out or reverse into the garage. It takes a long time to call the owner to move the car. In addition, the owner is busy at work and has no time to come, so the waiting time is even longer. Once someone else's car blocks the road, you have to wait for the owner to come and move the car. When moving the car, the owner or the person who has the key to the car must be on site to move the car.

[0003] With reference to the patent application with publication number CN107776570B, the method of the patent is to control the vehicle to automatically move forward when parking and search for available parking spaces on both sides of the vehicle during the process. When there are available parking spaces, the basic information of the target parking space is identified. The basic information of the target parking space includes the orientation, type, size, tilt angle of the target parking space, and the lateral distance between the vehicle and the target parking space. The type of the target parking space includes whether the target parking space is a parallel parking space, a vertical parking space, or an inclined parking space. Parking path planning is performed according to the basic information of the identified target parking space. According to the lateral spacing between the vehicle and the target parking space and the constraints, the distance from the parking starting point to the corresponding side of the target parking space and the parking path from the parking starting point to the parking end point are calculated. The method of the patent can realize automatic parking, but it cannot solve the problem that after the car is parked, if the way out is blocked by other vehicles, the owner of the car or the person with the car key must be contacted to be present. Summary of the invention

[0004] In view of the above defects or improvement needs of the prior art, the present invention proposes a method, device and vehicle controller for contactless control of automobile movement, so as to solve the problem that the owner or a person with the car key must be present to move the car.

[0035] like Figure 1 FIG. 1 is a flow chart of a method for contactless control of vehicle movement provided by an embodiment of the present invention. Figure 1 The method shown includes the following steps:

[0036] After receiving the instruction from the vehicle owner through the server to allow the vehicle to accept external control, the vehicle is controlled to enter the external control state, and a prompt instruction is issued to prompt that the vehicle is in the remote control mode;

[0037] The distance between the palm of the operator in front of the vehicle and the vehicle is detected by several distance sensors placed in the front grille of the vehicle;

[0038] The vehicle is controlled according to the distance between the operator's palm and the vehicle detected by each distance sensor.

[0039] Among them, three distance sensors are placed in parallel in the front air intake grille of the vehicle.

[0040] The specific implementation process is as follows Figure 2 As shown, the implementation of this patent is based on the following steps:

[0041] (1) Obtain the authorization of the vehicle owner: The vehicle owner sends an instruction allowing the vehicle to accept external control to the vehicle controller through the server, controlling the vehicle to enter the external control state. All parts of the sensors start to work and emit three "beep" sounds to tell people beside the vehicle that they can start controlling the vehicle;

[0042] (2) Install 3 juxtaposed distance sensors in the front air grille of the vehicle. The distances detected by each distance sensor are set as d1, d2, and d3. A preset distance, such as 40 cm, is set in advance for the three distance sensors;

[0043] (3) The controller places the hand in front of the distance sensor, and the palm moves forward parallel to the vehicle (i.e., away from the vehicle). At this time, the distances detected by the three distance sensors are all increasing, and the vehicle moves forward with the palm, keeping the distance between the distance sensor and the palm at 40 cm. As shown in, Figure 3 shown, Figure 3 the palm is simplified as a rectangle in;

[0044] (4) When the palm approaches the vehicle, the distance decreases, and the vehicle moves backward with the palm;

[0045] (5) When the palm rotates, the distances of the three distance sensors are different. The vehicle controller always keeps the front wheels of the vehicle perpendicular to the palm. As shown in, Figure 4 shown, Figure 4 the palm is simplified as a rectangle in;

[0046] Among them, the distances of the left, middle, and right sensors are d1, d2, and d3.

[0047] When the distances of all three distance sensors are greater than the preset distance (such as 40 cm) and d1 < d2 < d3, turn left;

[0048] When the distances of all three distance sensors are greater than the preset distance (such as 40 cm) and d1 > d2 > d3, turn right.

[0049] (6) When the vehicle is controlled to enter the appropriate position, the palm shakes left and right 3 times in the direction parallel to the distance sensor. The vehicle detects the same data 3 times within 2 seconds, exits the remote control mode, and emits a "beep" sound to prompt the controller;

[0050] (7) The vehicle controller sends an end message to the vehicle owner through the server.

[0051] Through the above technical solutions, the present invention can be implemented in a parking lot with poor environment, and the vehicle owner does not need to arrive at the scene to move the vehicle; moving the vehicle does not require contacting the vehicle and can be controlled outside the vehicle; there is no need to install a high-precision radar, reducing costs, making this technology can be widely promoted.

[0052] It should be pointed out that, according to the needs of implementation, the various steps / components described in this application can be split into more steps / components, and two or more steps / components or partial operations of steps / components can be combined into new steps / components to achieve the purpose of the present invention.

[0053] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
