Control device for vehicles
View Patent ↗There is described a remote controller for a vehicle. A storage module stores control data to be transmitted to an in-vehicle Transceiver. A transceiver switch has a transmit mode to transmit a data signal to the in-vehicle transceiver and a receive mode to listen for an acknowledgement signal from the in-vehicle transceiver. A user interface has at least one translucent key switch to contact the transceiver switch and thereby activate transmission of the data signal. A light source is provided beneath the translucent key switch to illuminate the translucent key switch when the acknowledgement signal has been received. Control circuitry is adapted to receive a command from the translucent key switch when it is depressed, retrieve the control data from the storage module, and provide the control data to the transceiver switch for transmission as the data signal, and to cause the light source to illuminate when the acknowledgement signal has been received.
1. A remote controller for a vehicle, the remote controller comprising:
a storage module for storing control data to be transmitted to an in-vehicle transceiver;
a transceiver switch having a transmit mode to transmit a data signal to said in-vehicle transceiver and a receive mode to listen for an acknowledgement signal from said in-vehicle transceiver;
a user interface having at least two translucent key switches to contact said transceiver switch and thereby activate transmission of said data signal;
at least two light sources, each beneath a corresponding one of said at least two translucent key switches to illuminate said corresponding one of said at least two translucent key switches only when said acknowledgement signal has been received and said corresponding one of said at least two translucent key switches has been released, thereby confirming that said acknowledgement signal has been received and which one of said at least two translucent key switches was depressed; and
control circuitry adapted to receive a command from one of said at least two translucent key switches when it is depressed, retrieve said control data from said storage module, and provide said control data to said transceiver switch for transmission of said data signal, and to cause, a corresponding one of said at least two light sources to illuminate only when said acknowledgement signal has been received and said one of said at least two translucent key switches has been released.
2. A remote controller as claimed in claim 1 , wherein said at least two light sources are light emitting diodes (LEDs).
3. A remote controller as claimed in claim 2 , wherein each one of said LEDs flashes a predetermined number of times when said acknowledgement signal is received.
4. A remote controller as claimed in claim 2 , wherein each one of said LEDs only flashes after said corresponding one of said at least two translucent key switches is released.
5. A remote controller as claimed in claim 1 , wherein said user interface comprises a secondary light source that illuminates when said data signal has been transmitted.
6. A remote controller as claimed in claim 1 , wherein said control circuitry causes an audio sound to be emitted from said remote controller when said acknowledgement signal has been received.
7. A remote controller as claimed in claim 1 , wherein said user interface comprises four translucent key switches, each one having a programmed functionality.
8. A remote controller as claimed in claim 1 , wherein said transceiver switch toggles between said transmit mode and said receive mode while one of said at least two key switches is depressed.
9. A method for transmitting a data signal from a handheld transceiver to a vehicle, the method comprising:
providing in said vehicle a remote starter module having an in-vehicle transceiver;
providing said handheld transceiver with a user interface having at least two key switches to activate transmission of said data signal, each one of said at least two key switches having a translucent cover and a light source beneath said translucent cover;
exerting pressure on one of said at least two key switches to cause a transceiver switch in said handheld transceiver to toggle between a transmit mode and a receive mode, wherein said data signal is transmitted from said handheld transceiver to said in-vehicle transceiver while said transceiver switch is in said transmit mode, and said handheld transceiver listens for an acknowledgement signal from said in-vehicle transceiver when said transceiver switch is in said receive mode;
releasing pressure on said one of said at least two key switches, thereby placing said transceiver switch in said receive mode for a predetermined amount of time; and
illuminating said light source located beneath said one of said at least two key switches upon said releasing pressure on said one of said at least two key switches only if said acknowledgement signal has been received, thereby confirming that said acknowledgement signal has been received and which one of said at least two key switches was depressed.
10. A method as claimed in claim 9 , wherein said toggle process is terminated when said handheld transceiver receives said acknowledgement signal from said in-vehicle transceiver.
11. A method as claimed in claim 9 , wherein said predetermined amount of time is two seconds.
12. A method as claimed in claim 9 , wherein said data signal is a door lock signal.
13. A method as claimed in claim 9 , wherein said data signal is an engine start signal.
14. A method as claimed in claim 9 , wherein said handheld transceiver provides an audio signal when said acknowledgement signal is received.
15. A method as claimed in claim 9 , wherein said light source is a light emitting diode.
16. A method as claimed in claim 9 , wherein said light source is programmed to flash a predetermined number of times, said number of times being indicative of a type of signal data.
