Abstract

A vehicle includes a vehicle door including a vehicle door handle that moves a door latch assembly between a latched configuration and an unlatched configuration. A door lock apparatus is operatively connected to the door latch assembly. An electric motor moves the door lock apparatus between a locked configuration to disallow operation of the door latch assembly using the vehicle door handle and an unlocked configuration that allows operation of the door latch assembly using the vehicle door handle. A door lock control system includes a door lock control zone that is provided on the vehicle door handle. The door lock control zone includes a touch sensor that provides a control signal to an ECU based on an operator touch. The ECU operates the electric motor based on the control signal.

First claim

What is claimed is:

1. A vehicle comprising:
a vehicle door comprising a vehicle door handle that moves a door latch assembly between a latched configuration and an unlatched configuration;
a door lock apparatus operatively connected to the door latch assembly;
an electric motor that moves the door lock apparatus between a locked configuration to disallow operation of the door latch assembly using the vehicle door handle and an unlocked configuration that allows operation of the door latch assembly using the vehicle door handle; and
a door lock control system comprising a door lock control zone that is provided on the vehicle door handle, the door lock control zone comprising a touch sensor that provides a control signal to an electronic control unit based on an operator touch, the electronic control unit operating the electric motor based on multiple operator contacts with the touch sensor within a predetermined time period to unlock the vehicle door;
wherein the electronic control unit includes logic that controls the electric motor based on the multiple operator contacts with the touch sensor within the predetermined time period, wherein the control signal is provided if the electronic control unit determines each operator contact with the touch sensor occurs for less than the predetermined time period.

2. The vehicle of claim 1 , wherein the door lock control zone is formed using a capacitive touch sensor.

3. The vehicle of claim 1 , wherein the vehicle door handle is an interior vehicle door handle, the door lock control zone provided on an inner facing surface of the interior vehicle door handle.

4. The vehicle of claim 1 , wherein the vehicle door handle is an exterior vehicle door handle, the door lock control zone provided on an exterior facing surface of the exterior door handle.

5. The vehicle of claim 1 further comprising a smart key vehicle entry system comprising a smart key ECU electronic control unit that receives a signal from a key fob and communicates with the ECU that controls the electric motor in response to the signal from the key fob.

6. The vehicle of claim 1 , wherein the door lock control zone is a first door lock control zone and the vehicle door handle is an interior vehicle door handle, the first door lock control zone provided on an inner facing surface of the interior vehicle door handle, the vehicle further comprising a second door lock control zone and an exterior vehicle door handle, the second door lock control zone provided on an exterior facing surface of the exterior vehicle door handle.

7. A method of controlling a door lock apparatus of a vehicle door, the method comprising:
determining that a touch sensor is actuated by an operator touch using an electronic control unit, the touch sensor being located in a door lock control zone that is provided on a vehicle door handle of the vehicle door;
determining that the touch sensor within the door lock control zone is actuated by another operator touch within a predetermined time period using the electronic control unit, the electronic control unit determining each operator touch with the touch sensor occurs for less than the predetermined time period; and
the electronic control unit controlling an electric motor operatively connected to the door lock apparatus based on determining that the touch sensor within the door lock control zone is actuated by the another operator touch within the predetermined time period and determining each operator touch with the touch sensor occurs for less than the predetermined time period to unlock the vehicle door.

8. The method of claim 7 , wherein the vehicle door handle is an interior vehicle door handle, the door lock control zone provided on an inner facing surface of the interior vehicle door handle.

9. The method of claim 7 , wherein the vehicle door handle is an exterior vehicle door handle, the door lock control zone provided on an exterior facing surface of the exterior door handle.

10. The method of claim 7 further comprising determining a presence of a key fob using a smart key electronic control unit, the smart key electronic control unit communicating the presence of the key fob to the electronic control unit that controls the electric motor.

11. The method of claim 7 , wherein the door lock control zone is a first door lock control zone and the vehicle door handle is an interior vehicle door handle, the first door lock control zone provided on an inner facing surface of the interior vehicle door handle, the vehicle further comprising a second door lock control zone and an exterior vehicle door handle, the second door lock control zone provided on an exterior facing surface of the exterior vehicle door handle.

12. A method of controlling a door lock apparatus of a vehicle door, the method comprising:
determining that a touch sensor is actuated by an operator touch using an electronic control unit, the touch sensor being located in a door lock control zone that is provided on a vehicle door handle of the vehicle door;
determining that the touch sensor within the door lock control zone is actuated by another operator touch within a predetermined time period using the electronic control unit;
determining that the touch sensor is actuated by the operator touch using the electronic control unit for less than the predetermined time period corresponding to a first tap;
determining that the touch sensor is actuated by another operator touch for less than the predetermined time period using the electronic control unit corresponding to a second tap; and
the ECU controlling an electric motor operatively connected to the door lock apparatus based on determining that the touch sensor within the door lock control zone is actuated by the operator touch for less than the predetermined time period corresponding to the first tap and the second tap and determining that the first tap and the second tap each occur within the predetermined time period.

13. The method of claim 12 , wherein the vehicle door handle is an interior vehicle door handle, the door lock control zone provided on an inner facing surface of the interior vehicle door handle.

14. The method of claim 12 , wherein the vehicle door handle is an exterior vehicle door handle, the door lock control zone provided on an exterior facing surface of the exterior door handle.

15. The method of claim 12 further comprising determining a presence of a key fob using a smart key electronic control unit, the smart key electronic control unit communicating the presence of the key fob to the electronic control unit that controls the electric motor.

16. The method of claim 12 , wherein the door lock control zone is a first door lock control zone and the vehicle door handle is an interior vehicle door handle, the first door lock control zone provided on an inner facing surface of the interior vehicle door handle, the vehicle further comprising a second door lock control zone and an exterior vehicle door handle, the second door lock control zone provided on an exterior facing surface of the exterior vehicle door handle.

17. The method of claim 12 , wherein the door lock control zone is formed using a capacitive touch sensor.
