Embodiment Construction

[0013] Referring now to the accompanying drawings, figure 1 A vehicle 10 equipped with a passive entry / passive start (PEPS) system 11 is shown in . The system unlocks the doors after completing the PEPS key 12 detection process. The system receives a wake-up signal when a person in possession of the key 12 touches a keyless entry keypad or other entry trigger device such as a switch on the door handle 14 located on the exterior surface of the driver's side door. In response to the wake-up signal, PEPS system 11 sends a low frequency, wireless interrogation signal from an antenna in door handle 16 to key fob 12, which sends a high frequency wireless response to RF receiver 18 in the vehicle. The master control module 20 receives and processes the data from the receiver 18, and if the detected key 12 is authorized for use with the vehicle 10 (as determined by the data in its response signal) and is located within about 1 meter of the door handle 16, Then the main control modul...

Abstract

A method for controlling mobilizing and immobilizing a vehicle using a valid passive entry-passive start key includes detecting that a vehicle operator exits the vehicle, determining that the key is absent from the vehicle, automatically immobilizing the vehicle by preventing vehicle propulsion; if a power source of the vehicle is immobilized after the operator exits the vehicle, automatically mobilizing the vehicle to allow vehicle propulsion when a key authorized to operate the vehicle is detected in the vehicle after a vehicle door is opened and closed, and automatically placing the vehicle in a low energy consumption operating state, if a reference period expires after the operator exits the vehicle with the power source running.

Description

technical field [0001] The present invention generally relates to controlling mobile and immobile operation of a vehicle when an authorized driver leaves the vehicle while a power source is running or does not re-enter the vehicle within a specified time. Background technique [0002] Passive Entry / Passive Start (PEPS) is a feature that allows a vehicle operator to enter the vehicle without actively using a key or remote transmitter, and it allows the operator to The vehicle engine can be started. PEPS does this through wireless communication between the vehicle and an approved key with which the driver enters and starts the vehicle. [0003] However, drivers may occasionally leave the vehicle with the powertrain or electrical system active, often through inadvertence. Leaving the powertrain enabled could allow the vehicle to be stolen or otherwise operated by an unauthorized driver. This is of particular concern for vehicles that operate without audible or otherwise dete...
