Abstract

A switch system for an automotive vehicle enables the driver to properly operate various devices mounted on the vehicle without reducing or limiting the driver'"'"'s field of view to any practical extent. In one form, the switch system includes a plurality of switches for operating various devices mounted on the vehicle; a switch selection detector for detecting which one of the switches is selected by a driver; a display for displaying the result of a driver'"'"'s switch selection detected by the switch selection detector as well as the operating conditions of the devices as a result of the driver'"'"'s switch selection; and a reflector in the form of a half mirror provided at a location above a dash board for reflecting the contents of the display so that the driver can watch the displayed contents of the display as reflected on the reflector. In another form, the reflector is omitted and the display is provided at a location above a dash board and below the driver'"'"'s sight line through a front windshield so as not to reduce the driver'"'"'s forward viewing field through the windshield so that the driver can watch the displayed contents of the display while watching the road ahead.

Claims

1. A switch system for an automotive vehicle comprising:

a plurality of switches disposed in a predetermined spatial orientation for operating various devices mounted on the vehicle;

a switch selection detector for detecting which one of said switches is selected by a driver;

display means for displaying the result of a driver'"'"'s switch selection detected by said switch selection detector as well as the operating conditions of the devices as a result of the driver'"'"'s switch selection; and

a reflector, provided at a location above a dash board, for reflecting the contents of said display means, said reflector providing the displayed contents of said display means to the driver along a display viewing sight line, which is oriented substantially in a same direction as, but below, a driver forward sight line,

wherein the reflected contents representative of the results of the driver'"'"'s manipulations of said switches are provided at locations corresponding to the spatial orientation of said switches.

2. A switch system according to claim 1, wherein said reflector comprises a half mirror positioned below said forward sight line.

3. A switch system according to claim 1, wherein said reflector comprises a front windshield having a lower portion. said lower portion reflecting the contents of the display means along said display viewing sight line.

4. A switch system according to claim 1, wherein said switches and said switch selection detector are mounted on a steering wheel in a facing relation to the driver.

5. A switch system according to claim 1, wherein said switches and said switch selection detector are mounted on said devices.

6. A switch system according to claim 1, wherein each of said switches includes an infrared LED and phototransistor pair, which are disposed on opposite sides of a corresponding switch, each of said infrared LEDs emitting a ray, that is detected by a corresponding phototransistor, said LED and phototransistor pairs detecting an interruption in a corresponding emitted ray when a user selects a corresponding switch.

7. A switch system for an automotive vehicle comprising:

a plurality of switches disposed in a predetermined spatial orientation for operating various devices mounted on the vehicle;

a switch selection detector for detecting which one of said switches is selected by a driver; and

display means for displaying the result of a driver'"'"'s switch selected detected by said switch selection detector as well as the operating conditions of the devices as a result of the driver'"'"'s switch selection, said display means being provided at a location above a dash board and below the driver'"'"'s sight line through a front windshield so as not to reduce the driver'"'"'s field of forward view through the windshield so that the driver can watch the displayed contents of said display means while watching the road ahead;

wherein contents of the display representative of the results of the driver'"'"'s manipulations of said switches are provided at locations corresponding to the spatial orientation of said switches.

8. A switch system according to claim 7, wherein said switches and said switch selection detector are mounted on a steering wheel in a facing relation to the driver.

9. A switch system according to claim 7, wherein said switches and said switch selection detector are mounted on said devices.

10. A switch system according to claim 7, wherein each of said switches includes an infrared LED and phototransistor pair, which are disposed on opposite sides of a corresponding switch, each of said infrared LEDs emitting a ray, that is detected by a corresponding phototransistor, said LED an phototransistor pairs detecting and interruption in a corresponding emitted ray when a user selects a corresponding switch.
