Embodiment Construction

[0040] FIG. 1 shows a motorized passenger vehicle 10 having driver's side doors 11 and 12 , passenger's side doors 13 and 14 , and a rear liftgate 15 . The passive entry system in the vehicle 10 creates user detection zones 16, 17 and 18 using short-range radio frequency (RF) communication signals via separate antennas (not shown) at respective vehicle door locations. Passive entry sensors for initiating door unlocking and / or opening may include a proximity / motion sensor 19 mounted below the liftgate 15 configured to: if the passive entry system detects an An authorized user, the passage of the user's foot is then sensed as an indication to open the liftgate 15 . The passive entry system may be configured as a Passive Entry / Passive Start (PEPS) system as disclosed in US Patent No. 9.580,046 entitled "Entry Assist System for a Motor Vehicle," which is incorporated herein by reference.

Abstract

Voice control is extended outside of an automotive vehicle by an access system associated with a door and window. An accelerometer is mounted on the window to generate a vibration signal. A passive entry system generates an unlock standby signal when an authorized user carrying a wireless fob is detected proximate the door. A voice recognizer in the vehicle is activated by the standby signal to scan the vibration signal for a spoken command for opening the door. A door actuator is activated by the voice recognizer when the command is detected.

Description

technical field [0001] The present invention relates generally to accessing a motor vehicle or vehicle functions using spoken voice commands outside the vehicle, and more particularly to an access system that uses a vehicle window as part of a microphone-like structure for detecting spoken voice commands. Background technique [0002] Passive keyless entry is a technology in which the user of a vehicle is able to unlock the doors without manually inserting a key into the lock. Alternatively, the user carries a wireless transponder or transceiver (ie, a key fob) that carries secure data that is automatically exchanged with the vehicle in order to authenticate the user. Touching the door handle is typically used to initiate an interrogation of the fob in a small area around the door. [0003] Some doors, such as the rear liftgate on a sport utility vehicle or the sliding side doors on a minivan, may include a powered actuator for opening the door. Activation of the power doo...
