Electronic control system using single receiver for different control modes
First Claim
1. An electronic control system comprising:
- a communication device carried by a user for transmitting a wireless signal;
a receiver for receiving the wireless signal from the communication device;
a transmitter for transmitting a wireless signal to the communication device;
a wireless control means for using the receiver to receive an operating signal transmitted from the communication device as the wireless signal to operate a specific device, the operating signal being generated by a manual operation of the communication device;
a smart control means for driving the transmitter to transmit a transmitter signal and using the receiver to receive a response signal from the communication device transmitted as the wireless signal in return to the transmitter signal, and automatically controlling the specific device in response to the response signal from the communication device; and
an arbitration means for granting a receiver usage privilege to one of the wireless control means and the smart control means, wherein the arbitration means supplies power to the receiver to operate the receiver if a receiver usage privilege acquisition instruction is output from either one of the wireless control means and the smart control means, assigns a receiver usage privilege to the wireless control means to enable the wireless control means to receive data if the receiver received the wireless signal, and assigns the receiver usage privilege to the smart control means if the receiver did not receive the wireless signal and the smart control means has output the usage privilege acquisition instruction.

Abstract
In a remote vehicle door control, a single receiver is used for both a wireless control whereby a door lock actuator is controlled according to an operating command transmitted by a wireless signal in conjunction with user operation of a communication device carried by a user, and a smart control whereby the door lock actuator is controlled automatically after completing a two-way communication process with the communication device. An arbitration means is provided to determine to which one of the wireless control and the smart control the receiver is assigned. If the receiver receives a wireless signal from the communication device, use of the receiver is assigned to the wireless control.

wherein the arbitration means stops power supply to the receiver and stops receiver operation, if a receiver usage privilege cancellation instruction is output from one of the wireless control means and the smart control means to which the receiver usage privilege has been assigned. -
3. An electronic control system as in claim 1,
wherein the smart control means executes a verification process to check if the communication device is an authorized communication device, and enables an automatic control of the specific device if the communication device is verified as an authorized device. -
4. An electronic control system as in claim 1, further comprising:
a usage privilege change means for checking if the receiver receives the operating signal from the communication device when the receiver use privilege has been assigned to the smart control means by the arbitration means, and instructing the smart control means to output the usage privilege cancellation instruction and instructing the arbitration means to assign the receiver usage privilege to the wireless control means if the receiver receives the operating signal.
-
5. An electronic control system as in claim 1,
wherein the arbitration means does not stop power supply to the receiver and assigns the receiver usage privilege to the smart control means if the smart control means is outputting the usage privilege acquisition instruction when the wireless control means completes a data receiving process and outputs the usage privilege cancellation instruction. -
6. An electronic control system as in claim 1,
wherein the specific device is a vehicle door lock actuator.

7. An electronic control system comprising:
-
a communication device capable of being carried by a user for transmitting a wireless signal including an operating signal capable of being generated by manual operation of the communication device, and a response signal;
a single receiver configured to receive the wireless signal from the communication device;
a transmitter configured to transmit a transmitter signal to the communication device;
a wireless control configured to receive the operating signal, the operating signal configured cause the wireless control to operate a specific device;
a smart control configured to;
cause the transmitter to transmit the transmitter signal, receive a response signal from the communication device in response to the transmitter signal, output a usage privilege acquisition instruction, and automatically control the specific device in response to receiving the response signal; and
an arbitrator configured to;
grant the single receiver a usage privilege to the wireless control means and enable the wireless control to receive data associated with operating the specific device if the operating signal was received by the single receiver, and grant the single receiver the usage privilege to the smart control to enable the transmitter to transmit the transmitter signal for a communication with the communication device to obtain a verification using the response signal if the operating signal was not received by the single receiver and if the smart control means has output the usage privilege acquisition instruction. - View Dependent Claims (8)
the communication device includes an actuator configured to generate the operating signal in response to operation of the actuator, and the communication device is configured to generate the response signal in response to the transmission signal from the transmitter when the actuator is not operated.
