Abstract

A system (SC) is intended to control a maneuver of a vehicle (V) via the establishment of two-way wireless communication between a communication module (MC1) of the vehicle (V) and a remote control unit (BC), following the actuation of the latter. This system (SC) comprises control means (MCT) designed to determine, over a duration corresponding to a chosen main number NP of successive connection events in their respective frequency channels, where NP>2, a first number of failed connection events, and then to compare this first number with a first chosen value and to modify the activated automatic maneuver in a chosen way if the first number is greater than or equal to this first value.

Claims

1. A method for remotely controlling a system for controlling at least one automatic maneuver of a vehicle via the establishment of two-way wireless communication between a remote control unit and a communication module of said vehicle, the method comprising:

following an actuation of said unit, said two-way communication being configured to result in an exchange of information, for the purposes of said activated automatic maneuver, between said unit and said communication module, in the course of connection events having a chosen duration, which are repeated periodically in frequency channels differing from one connection event (ECi) to another according to a predetermined hopping protocol, and which may be either successful or failed;

a step (i) in which a first number of failed connection events is determined over a duration corresponding to a chosen main number (NP) of successive connection events in their respective frequency channels, where NP>

2;

a step (ii) in which said first number is compared with a first chosen value; and

a step (iii) in which said activated automatic maneuver is modified in a chosen way if said first number is greater than or equal to said first value.

2. The method as claimed in claim 1, wherein, in said step (i), a second number of consecutive failed connection events is determined over said duration corresponding to the chosen main number of successive connection events in their respective frequency channels, wherein, in said step (ii), said second number is compared with a second chosen value, smaller than or equal to said first value, and wherein, in said step (iii), said activated automatic maneuver is modified in a chosen way if said second number is greater than or equal to said second value.

3. The method as claimed in claim 1, wherein, in said step (iii), said activated automatic maneuver is stopped if said first number is greater than or equal to said first value, or if said second number is greater than or equal to said second value.

4. The method as claimed in claim 1, wherein each connection event has a fixed duration in the range from about 5 ms to about 50 ms.

5. The method as claimed in claim 4, wherein said duration is equal to 20 ms.

6. The method as claimed in claim 1, wherein said main number is greater than or equal to 5.

7. The method as claimed in claim 6, wherein said first value is greater than or equal to 4.

8. The method as claimed in claim 7, wherein said second value is greater than or equal to 3.

9. The method as claimed in claim 1, wherein said two-way communication between said unit and said communication module of the vehicle is of a type chosen from a group comprising at least Bluetooth®

, ANT+ and Zigbee.

10. The method as claimed in claim 9, wherein said two-way communication between said unit and said communication module of the vehicle is of the Bluetooth Smart®

type.

11. The method as claimed in claim 1, wherein said automatic maneuver is chosen from a group comprising at least a maneuver for automatic parking in a parking place, a maneuver for automatic departure from a parking place, a maneuver for opening a side door of said vehicle, a maneuver for closing a side door of said vehicle, a maneuver for opening a tailgate or hatch of said vehicle, and a maneuver for closing a tailgate or hatch of said vehicle.

12. The method as claimed in claim 1, wherein the actuation of said unit is continuous.

13. A control system for controlling at least one automatic maneuver of a vehicle via establishment of two-way wireless communication between a communication module of said vehicle and a remote control unit,

wherein following the actuation of the latter, said two-way communication being configured to result in an exchange of information, for the purposes of said activated automatic maneuver, between said communication module and said unit, in the course of connection events having a chosen duration, which are repeated periodically in frequency channels differing from one connection event to another according to a predetermined hopping protocol, and which may be either successful or failed,

the control system comprising:

control means designed to determine, over a duration corresponding to a chosen main number (NP) of successive connection events in their respective frequency channels, where NP>

2, a first number of failed connection events, then to compare said first number with a first chosen value, and to modify said activated automatic maneuver in a chosen way if said first number is greater than or equal to said first value.

14. The system as claimed in claims 13, wherein said two-way communication is of a type chosen from a group consisting of:

at least Bluetooth®

, ANT+ and Zigbee.

15. The system as claimed in claim 14, wherein said two-way communication between said unit and said communication module of the vehicle is of the Bluetooth Smart®

type.

16. A remote control unit capable of remotely controlling a control system for controlling at least one automatic maneuver of a vehicle via establishment of two-way wireless communication between the unit and a communication module of said vehicle, following the actuation of the unit, said two-way communication being intended to result in an exchange of information, for the purposes of said activated automatic maneuver, between the unit and said communication module, in the course of connection events having a chosen duration, which are repeated periodically in frequency channels differing from one connection event to another according to a predetermined hopping protocol, and which may be either successful or failed, the remote control unit comprising:

control means designed to determine, over a duration corresponding to a chosen main number (NP) of successive connection events in their respective frequency channels, where NP>

2, a first number of failed connection events, then to compare said first number with a first chosen value, and to modify said activated automatic maneuver in a chosen way if said first number is greater than or equal to said first value.
