Problems solved by technology

[0002] In recent years, the traditional keyless access control system has been unable to meet the needs of consumers
Keyless entry systems with keyless entry (PKE: Passive Keyless Entry) and keyless start (PKS: Passive Keyless Start) functions have become mainstream, and the realization of these functions requires the cooperation of antennas on the body side, door handles, and trunks. The cooperation of the electronic lock switch button also requires human operation cooperation (for example, pressing the door handle or the button of the back box when opening the door) to realize, and the intelligent experience is poor

Abstract

The invention discloses a position identification device and method of a vehicle remote-control key and a vehicle. The device comprises first to Nth vehicle mounted antennae and a vehicle body control module, wherein N is a positive integer greater than 2, and the vehicle body control module is used for controlling the first to Nth vehicle mounted antennae to transmit first to Nth detection signal at preset intervals, sequentially receive the first to Nth response signal fed back by the vehicle remote-control key and respectively obtain the first to Nth distance information between the first to Nth vehicle mounted antennae and the vehicle remote-control key and obtaining the position of the vehicle remote-control key according to the first to Nth distance information. The position identification device of the vehicle remote-control key greatly improves the intelligentized experience of the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a position recognition device and method for a remote control key of a vehicle and a vehicle. Background technique [0002] In recent years, the traditional keyless access control system has been unable to meet the needs of consumers. Keyless entry systems with keyless entry (PKE: Passive Keyless Entry) and keyless start (PKS: Passive Keyless Start) functions have become mainstream, and the realization of these functions requires the cooperation of antennas on the body side, door handles, and trunks. The cooperation of the switch button of the electronic lock also needs human operation cooperation (such as pressing the door handle or the button of the back box when opening the door) to realize it, and the intelligent experience is poor. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain...
