Problems solved by technology

[0005] If such a system were used in a truck, the antenna would be located near the door handle to well above the truck's wheels, making it impossible to be sure that a CID located in the user's pocket or on the bottom of a bag near the user would be able to pick up the signal sent by the antenna
On the other hand, the range of the signal sent by the antenna cannot be very large to avoid unwanted CID activation and detection, which can happen when the driver is standing in front of the truck and cannot see the cab door at all
[0006] Therefore, until now, passive keyless entry systems have not been used in trucks

The antenna can be installed in a locker (4) below the cabin floor (29) or in a wheel arch (21A) of the truck.

Description

technical field [0001] The invention relates to a truck provided with a passive keyless entry system. Background technique [0002] Keyless systems are known to allow easy access to personal vehicles because the user does not have to use a key to open the door but only a customer identification device or CID, which is typically a In the form of remote controllers or electronic cards or electronic tags. [0003] Active keyless entry systems are systems in which the user activates a remote control, such as by pressing a button, to unlock the doors of the vehicle. A passive keyless entry system is a system in which a user has a customer authentication device that is able to exchange information with an on-board control unit without manual activation by the user. The present invention relates to passive keyless entry systems. [0004] Such a system uses an antenna, usually mounted near the handle of the corresponding door, as mentioned in WO-A-03 / 097971. In this arrangement,...
