Abstract

A vehicle user interface apparatus for a vehicle including a light emitting unit configured to emit light; a touch sensor configured to sense a touch; a processor configured to control the light emitting unit to emit the light in response to an event, activate the touch sensor when the light is emitted, and provide a signal to control a vehicle device corresponding to a touch input received through the activated touch sensor; and a cover covering the light emitting unit, the touch sensor, and the processor, the cover configured to transmit the light into a passenger compartment with a specific shape when the light is emitted.

First claim

What is claimed is:

1. A vehicle user interface apparatus for a vehicle, comprising:
a light emitting unit configured to emit light;
a touch sensor configured to sense a touch;
a processor configured to:
control the light emitting unit to emit the light in response to an event,
activate the touch sensor when the light is emitted, and
provide a signal to control a vehicle device corresponding to a touch input received through the activated touch sensor; and
a cover covering the light emitting unit, the touch sensor, and the processor, the cover configured to transmit the light into a passenger compartment with a specific shape when the light is emitted,
wherein the cover includes:
a pattern member having a pattern corresponding to the specific shape, the pattern member configured to transmit the light through the pattern;
a film member having a prescribed light transmissivity to output the light, transmitted through the pattern, to an outside, wherein the touch sensor is positioned to correspond to a location of the pattern; and
a surface formed of the same material as a material forming a vehicle interior part and provided on the film member, wherein a region of the surface corresponding to the location of the pattern is thinner than a region of the surface not corresponding to the location of the pattern,
wherein, when a predetermined time passes after light is generated, the processor is configured to control the light emitting unit not to output the light and deactivate the touch sensor,
wherein the light emitting unit is located near a driver seat in the passenger compartment,
wherein the shape is an ignition button shape,
wherein the processor is further configured to provide a signal to control any one function among a plurality of control functions of an ignition device in response to the touch input,
wherein the processor is further configured to control the light emitting unit based on vehicle information, and
wherein the processor is further configured to:
receive vehicle speed information included in the vehicle information,
control the light emitting unit not to emit light when a vehicle speed value is not zero, and
control the light emitting unit to emit light when an emergency situation occurs when the vehicle speed value is not zero.

2. The vehicle user interface apparatus according to claim 1 , wherein the surface includes a synthetic resin material, a fabric material, a leather material, a wood material, or a metal material.

3. The vehicle user interface apparatus according to claim 1 , further comprising:
a transparent flexible printed circuit board on which the touch sensor and the processor are disposed.

4. The vehicle user interface apparatus according to claim 1 , further comprising:
a light guide film configured to transmit the light emitted by the light emitting unit to the cover,
wherein the light guide film includes:
a first light guide film;
a second light guide film interposed between the first light guide film and the cover;
a third light guide film provided on the first light guide film, and
wherein an etching portion is provided on the first light guide film or the second light guide film and the etching portion is formed to correspond to the shape.

5. The vehicle user interface apparatus according to claim 4 , wherein the etching portion is provided on a surface of the first light guide film, which comes into contact with the third light guide film, or the etching portion is provided on a surface of the second light guide film, which comes into contact with the first light guide film,
wherein light is introduced into the first light guide film and the second light guide film along different paths, and
wherein the light guide film uniformly transmits the light emitted by the light emitting unit to the cover.

6. The vehicle user interface apparatus according to claim 4 , further comprising at least one of:
an optical clear film to guide the light emitted by the light emitting unit to the light guide film;
a color film to change a wavelength of the light emitted by the light emitting unit; and
a plastic member to support reflection of the light emitted by the light emitting unit.

7. The vehicle user interface apparatus according to claim 6 , wherein the plastic member comprises an injection molded plastic member including the light emitting unit, the touch sensor, and the processor disposed on the cover.

8. The vehicle user interface apparatus according to claim 1 , wherein the processor is further configured to:
control the light emitting unit to emit light in response to a first touch when the first touch is sensed by the touch sensor, and
provide the signal to control the vehicle device in response to a second touch when the second touch is sensed by the touch sensor.

9. The vehicle user interface apparatus according to claim 1 , further comprising:
a circuit board on which the light emitting unit is mounted using an optical soldering technique.

10. The vehicle user interface apparatus according to claim 1 , wherein the plurality of control functions includes:
a first function of starting the vehicle;
a second function of turning on an electronic device provided in the vehicle; and
a third function of turning off the vehicle.

11. The vehicle user interface apparatus according to claim 1 , further comprising:
a haptic output unit configured to output a vibration pattern corresponding to one of the plurality of control functions based on control of the processor.

12. The vehicle user interface apparatus according to claim 1 ,
wherein the vehicle information includes at least one of vehicle location information, the vehicle speed information, gear lever position information, door opening/closing information, safety belt status information, brake pedal position information, Idle Stop and Go function on/off information, passenger information, driver's biometric information, seat position information, and audio volume control information.

13. The vehicle user interface apparatus according to claim 12 , wherein the processor is further configured to:
receive the door opening/closing information, and
control the light emitting unit to emit light upon receiving information related to opening of a driver's seat door.

14. The vehicle user interface apparatus according to claim 12 , wherein the processor is further configured to:
receive the safety belt status information, and
control the light emitting unit to emit light upon receiving information related to a fastened status of a safety belt of a driver seat or emit light upon receiving information related to a fastened status of safety belts of all seats on which passengers are located.

15. The vehicle user interface apparatus according to claim 12 , wherein the processor is further configured to:
