Method and device for monitoring that a vehicle in standby mode is correctly immobilized for transport, and vehicle equipped with such a device

11:

• A method for monitoring that a vehicle in standby mode is correctly immobilized for transport following installation of the vehicle on a transport carrier, the vehicle including a course control device, wheel speed sensors and a vehicle yaw speed sensor linked to the course control device of the vehicle, a detected information processing unit, of on-board computer type, managing modes of operation of the vehicle, and a vehicle immobilizing device, the method comprising:
• detecting a standby mode of operation of the vehicle when stopped following installation of the vehicle fixed on a transport carrier;
• detecting a zero speed of the vehicle, recorded by the wheel speed sensors of the vehicle following the installation of the vehicle on the transport carrier, over a predefined time period;
• detecting a non-zero yaw speed of the vehicle, recorded by the yaw speed sensor of the vehicle, corresponding to relative movement of the vehicle fixed on its carrier, over a predefined time period;
• detecting a non-zero speed of the vehicle on at least two wheels of the vehicle over a determined time period and over a low displacement amplitude;
• under these conditions, determining a mode for transport and for monitoring correct immobilization for transport of the vehicle, stored by the information processing unit, in which the course control device orders retightening of the vehicle immobilizing device at least once to immobilize the vehicle and disables the control to avoid producing unnecessary tightening forces of the vehicle immobilizing device resulting, or to avoid defects requiring a diagnostic-based technical intervention;
• and
• allowing for an exit from the mode for transport and for monitoring the correct immobilization of the vehicle and the standby mode, corresponding to the vehicle being switched on again.

18:

• A device for monitoring that a vehicle in standby mode is correctly immobilized for transport for implementing the method defined as claimed in claim 11, comprising:
• vehicle wheel speed sensors;
• a vehicle yaw speed sensor;
• a vehicle course control device, or of E.S.C. (vehicle stability control) type;
• an information processing unit of computer type on board the vehicle configured to manage modes of operation of the vehicle;
• a device comprising means for detecting the vehicle in a mode for transport and for monitoring that the vehicle is correctly immobilized for transport, stored by the information processing unit, in which the course control device orders retightening of the vehicle immobilizing device at least once and a limited number of times to immobilize the vehicle and is adapted to disable the control to avoid producing unnecessary vehicle brake tightening forces and causing defects requiring a diagnostic-based technical intervention, and for enabling the vehicle to be switched on again, or to be switched on again when a door is opened or when the vehicle is moved.
