Abstract

The invention relates to a method for interactively controlling the automatic parking of a motor vehicle ( 10 ) in a parking space ( 50 ) by means of a mobile terminal ( 30 ), involving the following steps: selection by the user of an automatic parking mode of the motor vehicle, and —automatic parking of the motor vehicle during the course of which the vehicle computer ( 21 ) controls the orientation of the wheels ( 13 ) and the power train ( 14 ) of the motor vehicle. According to the invention, each piece of information emitted by the obstacle detection assistance means ( 25, 26 ) fitted to the motor vehicle is transmitted to the mobile terminal in order to signal the possible presence of an obstacle ( 60 ) to a user located outside of the motor vehicle.

First claim

The invention claimed is:

1. A method for interactive control of the automatic parking of a motor vehicle in a parking space by a mobile terminal that comprises a display screen, said method comprising:
displaying, on the display screen of the mobile terminal, a message that prompts a user to identify the motor vehicle to be parked from among a plurality of vehicles;
selection, by the user, of an automatic parking mode for parking the motor vehicle;
selection, by the user and on the display screen of the mobile terminal, of a type of maneuver for parking the motor vehicle from a group consisting of: parking at an angle, perpendicular forward parking, perpendicular parking in reverse, and parallel parking;
automatic parking of the motor vehicle, in the course of which a computer controls a wheel orientation controller that controls the orientation of the wheels of the motor vehicle and a power train controller that controls a power train of the motor vehicle according to information received from at least one obstacle detection assistant;
transmission by the computer, according to data received from each obstacle detection assistant, a piece of the information to a user interface located in a passenger compartment of the motor vehicle to inform the user of the possible presence of an obstacle; and
transmission of said information, in the course of the automatic parking step, by the computer to the mobile terminal to indicate the possible presence of an obstacle to a user located outside the motor vehicle.

2. The method for interactive control as claimed in claim 1 , wherein said motor vehicle comprises a plurality of obstacle detection assistants each for transmitting different data to the computer, the method further comprising:
preparing by the computer, in the course of the automatic parking step, a plurality of pieces of information according to said data; and
selection, by the user with the assistance of the mobile terminal, from among said prepared information, at least one piece of information to be displayed on said display screen.

3. The method for interactive control as claimed in claim 1 , wherein said information is included in the following list:
an image acquired by a camera provided on the motor vehicle,
a recreated image, prepared according to a plurality of images acquired by a plurality of cameras provided on the motor vehicle,
a pattern illustrating the trajectory of the motor vehicle, to be superimposed on said acquired image or on said recreated image,
a pattern indicating an obstacle, to be superimposed on said acquired image or on said recreated image,
a sound warning indicating an obstacle,
a visual warning indicating an obstacle,
a vibration indicating an obstacle,
a distance before hitting an obstacle, or
an indicator relating to a set of maneuvers that the motor vehicle is able to execute.

4. The method for interactive control as claimed in claim 1 , wherein said motor vehicle comprises at least two cameras, the method further comprising:
placing by the mobile terminal, in the course of said automatic parking step, at the disposal of the user, a selector that enables the user to choose the display on the display screen of the images acquired by either the one or the other of the cameras.

5. The method for interactive control as claimed in claim 1 , wherein the mobile terminal comprises:
an acquirer that acquires at least one control instruction for controlling the motor vehicle issued by the user; and
a transmitter that transmits this control instruction to the motor vehicle's computer,
the method further comprising, in the course of said automatic parking step, controlling, by the computer, the wheel orientation controller and the power train controller according to each control instruction received from the mobile terminal.

6. The method for interactive control as claimed in claim 5 , wherein said control instruction is included in the following list:
an instruction for turning the lighting of the motor vehicle on or off,
the type of maneuver to be executed,
a gear to be engaged,
an instruction to interrupt the parking maneuver,
an instruction to continue the parking maneuver, or
an item of data relating to the user's ability to continue the parking maneuver.

7. The method for interactive control as claimed in claim 1 , wherein, prior to said automatic parking step, a step of networking the mobile terminal with the motor vehicle's computer is provided in the course of which the mobile terminal and the computer exchange at least one item of networking data.

8. The method for interactive control as claimed in claim 7 , wherein said item of networking data is included in the following list:
a communication language for the user,
a piece of information characterizing the motor vehicle,
a piece of information characterizing the mobile terminal,
a piece of information supplying the version of an application stored in the motor vehicle's computer,
a piece of information supplying the version of an application stored in the mobile terminal, or
a priority status of the application stored in the mobile terminal.
