Abstract: A method for transmitting in a passive activation system in a motor vehicle. Between each use-case module and a protocol driver an intermediate management layer is inserted that receives requests from the modules and stores them in a list according to oldness and priority ranking, selects a main request with the highest priority ranking, selects requests compatible with the main request, sends at least one grouped signal corresponding to the main and compatible requests to a portable activation device, receives back from the activation device at least one signal transmitted to the intermediate layer allowing the activation device to be located and then the location thereof to be sent to the case modules that sent the main request or a compatible request, and deletes the main and compatible requests from the list.

Abstract: A computer for activating at least one function of a motor vehicle from a portable authentication device, the vehicle including: a plurality of opening elements, a plurality of communication modules, each communication module being mounted in an opening element of the vehicle, a fixed reference module, the computer being configured to: determine the opening position of the at least one opening element detected in the open state, determine an inner detection zone, located in the passenger compartment of the vehicle, and an outer detection zone of the antenna, located outside the vehicle, from the determined opening position, calculate the position of the device, and activate at least one function of the vehicle when the authentication device is located in the inner detection zone of said opening element.

Abstract: A method for testing at least one transmitting antenna of a vehicle, in particular a motor vehicle, using a test computer and an electronic key.

Abstract: A method for the activation by a user with a portable device of at least one function of a piece of motor vehicle equipment. The vehicle having a plurality of predefined areas (around and/or inside the vehicle) and including a plurality of pieces of equipment, each capable of implementing at least one function, and a management system for controlling the pieces of equipment. The method includes the user performing a predefined movement of the device in at least one predefined vehicle area, the management system determining the movement performed by the user with the device and the area or areas in which the movement is performed, associating the movement performed and the area or areas in which the movement is performed with at least one function of at least one of the vehicle's pieces of equipment, and activation by the management system of the at least one associated function.
