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

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 via the vehicle immobilizing device following installation of the vehicle fixed on a transport carrier;
• detecting a speed of the vehicle, recorded by the wheel speed sensors of the vehicle following the installation of the vehicle on the transport carrier;
• detecting a yaw speed of the vehicle, recorded by the yaw speed sensor of the vehicle, corresponding to relative movement of the vehicle fixed on the transport carrier;
• retightening of the vehicle immobilizing device at least once to immobilize the vehicle when the detecting the speed of the vehicle detects a non-zero speed over a predefined time period or the detecting the yaw speed of the vehicle detects a non-zero yaw speed over a predefined time period;
• after the retightening of the vehicle immobilizing device at least once to immobilize the vehicle, preventing further retightening of the vehicle immobilizing device when the detecting the speed of the vehicle detects subsequent non-zero speeds or the detecting the yaw speed of the vehicle detects subsequent non-zero yaw speeds to avoid producing additional tightening forces of the vehicle immobilizing device;
• and
• exiting from the standby mode, corresponding to the vehicle being switched on again.
