System for passive entry and passive start for a motor vehicle
First Claim
1. A system for passive entry and/or passive start for a motor vehicle, the system comprising:
- an antenna group;
an electronic control unit designed to be coupled to the motor vehicle, the electronic control unit being configured to control the antenna group to cooperate with a portable recognition device carried by a user to enable the entry and/or start of the motor vehicle;
wherein the antenna group includes at least a first antenna and a second antenna, designed to operate within a frequency range, and according to a communications protocol of the Bluetooth standard, and each having a respective radiation lobe; and
a casing designed to be rigidly coupled to the motor vehicle and configured to house, in an integrated manner, the first and second antennas and the electronic control unit;
wherein the casing is designed to be arranged inside an interior compartment of the motor vehicle, in a front middle position, so that the respective radiation lobes of the first and second antennas are directed towards a first and a second door of the motor vehicle, arranged on opposite sides with respect to a longitudinal symmetry axis of the motor vehicle.
