START SYSTEM FOR A MOTOR VEHICLE
First Claim
1. A start system for a motor vehicle, comprising;
- a vehicle bus system disposed in the motor vehicle;
a powertrain control module connected to the vehicle bus system, the powertrain control module including;
an engaged state electrically enabling the powertrain control module to provide tractive power to a vehicle drive wheel; and
a disengaged state electrically inhibiting the powertrain control module from providing tractive power to the vehicle drive wheel or an other vehicle drive wheel;
an electronic pattern-entry user interface; and
an authentication system in communication with the vehicle bus system and with the electronic pattern-entry user interface, the authentication system being responsive to an entered pattern entered on the electronic pattern-entry user interface while the powertrain control module is in a current instance of the disengaged state;
wherein the powertrain control module enters the engaged state only in response to an authenticated engagement command communicated from the authentication system to the powertrain control module in response to authenticating the entered pattern.

Abstract
A start system includes a vehicle bus system disposed in a motor vehicle. A powertrain control module is connected to the vehicle bus system. The powertrain control module includes an engaged state electrically enabling the powertrain control module to provide tractive power to a vehicle drive wheel, and a disengaged state electrically inhibiting the powertrain control module from providing tractive power to the vehicle drive wheel or another vehicle drive wheel. An authentication system is in communication with the vehicle bus system and with an electronic pattern-entry user interface. The authentication system is responsive to an entered pattern entered on the interface while the powertrain control module is in a current instance of the disengaged state. The powertrain control module enters the engaged state only in response to an authenticated engagement command communicated from the authentication system to the powertrain control module in response to authenticating the entered pattern.

13. A method for starting a motor vehicle, comprising:
-
recognizing an engine on event of the motor vehicle at a powertrain control module in communication with a vehicle bus system operatively disposed in the motor vehicle; in response to recognizing the engine on event, transmitting an authentication request from a verification module to a device having an electronic pattern-entry user interface; receiving an entered pattern entered on the electronic pattern-entry user interface; recognizing, by an authentication system in communication with the vehicle bus system and with the electronic pattern-entry user interface, that the entered pattern is an authenticated pattern; and in response to the recognizing that the entered pattern is the authenticated pattern, transmitting an authenticated engagement command to the powertrain control module to instruct the powertrain control module to enter into an engaged state, the engaged state electrically enabling the powertrain control module to provide tractive power to a vehicle drive wheel. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
