Abstract

A keyless entry system for a vehicle comprises a keyless entry pad having a plurality of keys. Each key has a corresponding symbol, and the symbols collectively form a textual representation of the vehicle and/or a user of the vehicle. A plurality of sensors in register with the keys for detecting the presence of a finger on each of the keys is coupled to an entry door latch for sending an unlock signal to the latch when a keyless entry code is entered a by selecting the keys with the finger in a predetermined sequence. When the latch is unlocked, the latch can be operated to open the entry door, such as with a door handle. The keyless entry system can be integrated with the door handle.

Claims

1. A vehicle door handle assembly mounted to a door and coupled with a latch operable between a locked condition, wherein the door is prevented from opening, and an unlocked condition, wherein the door can be opened, the vehicle door handle assembly comprising:

a handle housing pivotally mounted to the door, and having a latch actuator;

a grip cover for complementary engagement with the handle housing to define with the handle housing a door handle grip, the grip cover incorporating at least one key identified with at least one non-numeric symbol, the at least one key being immovable relative to the grip cover;

a sensor keypad comprising at least one sensor coupled with the latch, the at least one sensor being selectively light-transmissive;

an illumination source assembly including at least one light source, the illumination source assembly being adapted for selective illumination to selectively backlight the at least one sensor and the at least one key; and

an illumination source holder for holding the illumination source assembly to the handle housing;

wherein the sensor keypad is disposed between the illumination source assembly and grip cover so that the at least one sensor is in proximate, operable registry with the at least one key and is activated when an object is in the vicinity of the sensor; and

wherein a selected sequence of the at least one non-numeric symbol can define a lock/unlock code so that selection of the at least one non-numeric symbol in the selected sequence can activate the at least one sensor according to the lock/unlock code to selectively place the latch in the locked condition or the unlocked condition.

2. The vehicle door handle according to claim 1, wherein the grip is a strap grip.

3. The vehicle door handle according to claim 1, wherein the illumination source is coupled to the sensor keypad such that selecting the at least one key illuminates the light source in register with the selected key.

4. The vehicle door handle according to claim 3, wherein the illumination source backlights the at least one key in response to at least one of the following:

a user touching the at least one key, a user touching the vehicle door handle, a user actuating a turn signal, a user activating a fob associated with the vehicle, a fob associated with the vehicle being located within a predetermined distance of the vehicle, and a user opening the door from inside the vehicle.

5. The vehicle door handle according to claim 1, wherein the illumination source comprises light emitting diodes.

6. The vehicle door handle according to claim 1, wherein the sensors comprise field effect sensors.

7. The vehicle door handle according to claim 1, wherein the at least one symbol comprises at least one of a make and a model of the vehicle.

8. The vehicle door handle according to claim 1, wherein the at least one symbol comprises only letters.

9. The vehicle door handle according to claim 1, wherein the at least one symbol comprises a combination of letters and numbers.

10. The vehicle door handle according to claim 1, wherein the at least one symbol comprises a logo associated with the vehicle.

11. The vehicle door handle according to claim 1, wherein the at least one symbol comprises a name of the user.

12. The vehicle door handle according to claim 1, wherein the at least one symbol comprises a name of a favorite sports team of the user.

13. The vehicle door handle according to claim 1, wherein the illumination source is coupled to the sensors such that selecting one of the keys illuminates the light source in register with the selected key.
