The invention relates to a wireless control system and method for wireless control of a remote electronic system from a vehicle, and in particular, to a wireless control system and method for recalling status information of a remote electronic system from a vehicle.
In the field of wireless control of remote electronic systems, technological advances have been developed to improve convenience, security, and functionality for the user. One example is a trainable transceiver for use with various remote electronic systems, such as security gates, garage door openers, lights, and security systems. A user trains the trainable transceiver by, for example, transmitting a signal from a remote controller in the vicinity of the trainable transceiver. The trainable transceiver learns the carrier frequency and data code of the signal and stores this code for later retransmission. In this manner, the trainable transceiver can be conveniently mounted within a vehicle interior element (e.g., visor, instrument panel, overhead console, etc.) and can be configured to operate one or more remote electronic systems.
Further advances are needed in the field of wireless control of remote electronic systems, particularly in the case of using automotive electronics to control remote electronic systems. As automotive manufacturers are adding increased electronic systems to the vehicle to improve convenience, comfort, and productivity, simplifying the interface and control of these electronic systems is also becoming increasingly important. In addition, as automotive manufacturers are adding increased electronic systems to the vehicle, providing greater and more refined control over more systems is also becoming increasingly important.
The operator of a trainable transceiver often will activate the trainable transceiver to actuate a remote electronic system as a vehicle is either approaching or leaving the location of the remote electronic system. Often, the operator is not able to immediately ascertain whether the actuation of the device was successful. The actuation can fail based on signal interference, incomplete activation of the trainable transceiver, battery/power failures, etc. Unknown failure of the remote electronic system can cause concern, for example where a garage door fails to close as an operator drives away, leaving the garage open and exposed. Accordingly, an operator is often forced to monitor the remote electronic system to ensure successful operation.

The status data on the wireless status signal may include a “SUCCESS” status indicative that the control signal was properly received and the control function was successfully executed by remote electronic system 18. The wireless status signal may be sent upon completion of the function specified in the wireless control signal. The status data may also be an “ACKNOWLEDGE” status indicative that a proper wireless control signal was received by transceiver circuit 53. According to an alternative embodiment, remote electronic system 18 can send a plurality of “IN PROCESS” status signals until completion of the operation whereupon a “SUCCESS” or “FAILURE” status signal may be sent. According to yet more alternative embodiments, the wireless status signal may include other information relevant to remote electronic system 18 for transmittal to wireless control system 12. Examples can include whether a garage door is open or closed or moving between open and closed position, whether a security system is armed or disarmed, whether a light is on or off, etc.
Wireless control system 12 includes a control circuit 30 configured to control the various portions of system 12, to store data in memory 31, to operate preprogrammed functionality, etc. Control circuit 30 may include various types of control circuitry, digital and/or analog, and may include a microprocessor, microcontroller, application-specific integrated circuit (ASIC), or other circuitry configured to perform various input/output, control, analysis, and other functions to be described herein. Control circuit 30 is coupled to an operator input device 32 which includes one or more push button switches 34 (see
Control circuit 30 is further coupled to a display 36 which includes a light-emitting diode (LED) or organic LED (OLED), such as, display element 38. Display 36 may alternatively include any other display elements as known in the art, for example but not limited to a liquid crystal display (LCD), a vacuum florescent display (VFD), or other display elements. Display element 38 can include a single multi-colored LED (e.g., green, red, and yellow) or multiple LEDs, each representing a different color.
Wireless control system 12 further includes a transceiver circuit 54 including transmit and/or receive circuitry configured to communicate via antenna 56 with remote electronic system 18. Transceiver circuit 54 is configured to transmit wireless control signals having control data which will control remote electronic system 18. Transceiver circuit 54 is further configured to receive wireless status signals including status information from remote electronic system 18. The wireless control system 12 and remote electronic system 18 may communicate using any wireless standard, including but not limited to WiFi, WiMax, Bluetooth™, infrared, radio frequency (RF), etc.
In operation, wireless control system 12 is configured to receive one or more characteristics of an activation signal sent from an original transmitter. An original transmitter is a transmitter, typically a hand-held transmitter, which is sold with remote electronic system 18 or as an after-market item, and which is configured to transmit an activation signal at a predetermined carrier frequency and having control data configured to actuate remote electronic system 18. For example, the original transmitter can be a hand-held garage door opener transmitter configured to transmit a garage door opener signal at a frequency, such as 355 megahertz (MHz), wherein the activation signal has control data, which can be a fixed code or a cryptographically-encoded code. Remote electronic system 18 is configured to open a garage door, for example, in response to receiving the activation signal from the original transmitter.
Transceiver 54 is configured to receive one or more characteristics of the activation signal from the original transmitter or from another source, which characteristics can include the frequency, control data, modulation scheme, etc. In this embodiment, transceiver 54 is configured to learn at least one characteristic of the activation signal by receiving the activation signal, determining the frequency of the activation signal, and demodulating the control data from the activation signal. Wireless control system 12 can be a Homelink™ trainable transceiver, manufactured by Johnson Controls Interiors LLC, and may be constructed according to one or more embodiments disclosed in U.S. Pat. Nos. 6,091,343, 5,854,593 or 5,708,415, which are herein incorporated by reference in their entirety. Alternatively, wireless control system 12 can receive one or more characteristics of the activation signal by other methods of learning. For example, the one or more characteristics of the activation signal can be preprogrammed into memory during manufacture of wireless control system 12 or can be input via operator input device 32 (which can include a key pad, buttons, etc.). In this manner, wireless control system 12 need not actually receive the activation signal in order to receive characteristics of the activation signal. Wireless control system 12 can receive the characteristics of the signal by any of these methods and store the characteristics of the activation signal in memory.
Transceiver circuit 54 is configured, under control from control circuit 30, to generate a carrier frequency at any of a number of frequencies in the ultra-high frequency range, preferably between 20 and 470 megahertz (MHz), more specifically between 280 and 430 MHz, wherein the control data modulated on to the carrier frequency signal may be frequency shift key (FSK) or amplitude shift key (ASK) modulated, or may use another modulation technique. The control data on the wireless control signal may be a fixed code or a rolling code or other cryptographically encoded control code suitable for use with remote electronic system 18.

In operation, wireless control system 12 is configured for wireless control of remote electronic system 18. Wireless control system 12 is configured to monitor the status of the control operation and to communicate that status to a user of wireless control system 12. For example, wireless control system 12 can be configured to transmit a wireless control signal from a vehicle to a garage door opener, as will now be described with reference to
According to yet another embodiment, activation can be automated. For example, in a wireless control system 12 including a navigation input device, wireless control system 12 can be configured to transmit the wireless control signal whenever the transmitter is within a predetermined distance to or from the location of the remote electronic system 18. Other examples of automation can include sending the signal based upon timing information, based on time of day information, or any other event-driven or user determined transmittal of the wireless control signal.
At step 64, control circuit 30 can turn on a display, for example turn on display element 38 (e.g., an LED which illuminates RED), that indicates to the user that wireless control system 12 has been activated. Alternative embodiments can include different feedback to the user dependent on the feedback capability associated with wireless control system 12. For example, where wireless control system 12 includes a display capable of displaying alphanumeric characters, the display can include a message such as “SIGNAL SENT,” or an audio system can audibly signal feedback to the user. At step 66, control circuit 30 can transmit a wireless control signal 68 using transceiver circuit 54. The control circuit 30 will then be placed in a “listening” or receiving mode where control circuit 30 is monitoring transceiver 54 to receive an acknowledgement signal from remote electronic system 18. Where an acknowledgment signal is not received within a specified time, such as one second, control circuit 30 can be configured to retransmit the signal without requiring another activation of operator input device 32. Periodically retransmitting wireless control signal 68 will help the system to correct for temporary interference or lack of signal strength in some cases. Control circuit 30 can be configured to retransmit the wireless control signal for a specified number of iterations until receipt by remote electronic system 18 is acknowledged. If the number of iterations exceeds a specified number, the control circuit can communicate a failure to the user of the system by, for example, flashing the red LED.
At step 70, wireless control signal 68 transmitted in step 66 is received by remote electronic system 18 through transceiver circuit 53. Upon receipt, remote electronic system 18 can perform a verification step. Where the signal is valid, remote electronic system 18 can transmit a wireless status signal 74 (e.g., an acknowledgement signal 74) in a step 72 using transceiver circuit 53. In a step 76, wireless control system 12 can receive acknowledgement signal 74. At a step 78, wireless control system 12 can indicate acknowledgement of the wireless control signal to the user of wireless control system 12 by displaying an acknowledgement indicator, such as by turning the red LED yellow and blinking. Upon receiving the acknowledgement signal, wireless control system 12 can be placed in a second listening mode where control circuit 30 is monitoring transceiver 54 to receive a wireless status signal. The second listening mode can include a timing limit where control circuit 30 will indicate an error condition if the wireless status signal is not received within a predetermined time limit. If the wireless status signal is not received within the predetermined time limit, control circuit 30 can use display 36 to indicate a failure condition. According to alternative embodiments, alternative types of feedback can be used to indicate that the wireless control signal was received and acknowledged by remote electronic system 18 or that a failure condition has occurred.
After sending the acknowledgement signal in step 72, remote electronic system 18 can perform the function designated by wireless control signal 68 in a step 80. For example, where remote electronic system 18 is a garage door opener, remote electronic system 18 can open or close the garage door in response to receipt of wireless control signal 68. According to alternative embodiments, wireless control signal 68 can include more robust control over remote electronic system 18. Using the garage door opener example, wireless control signal 68 can include an up-only control signal. An up only signal will only activate the garage door opener if the garage door is not already up. If the garage door is up, remote electronic system 18 can be configured to do nothing.
Following completion of the function in step 80, remote electronic system 18 can be configured to transmit a wireless status signal 84 in a step 82. Wireless status signal 84 can be a message indicating that remote electronic system 18 attempted to perform the function. Where the remote electronic system 18 has the capability to verify the success of an operation, remote electronic system 18 can await completion of the operation and then send wireless status signal 84 including information regarding the success or failure of the function or even reasons for failure of the operation. Exemplary information can include garage door closed, garage door open, garage door operation failed, garage door operation failed because of obstruction, etc. In a step 86, wireless control system 12 can receive and interpret wireless status signal 84. The received and interpreted status signal is stored in memory at step 87 for later retrieval by control circuit 30. Where wireless status signal 84 indicates success, wireless control system 12 can display a status indicator which displays a corresponding success status, such as turning the display element LED green for a period to indicate success in a step 88. Following step 88, wireless control system 12 can reset in a step 90.
According to alternative embodiments, feedback to the user of wireless control system 12 can take a variety of different forms including different levels of content. For example, where wireless control system 12 includes an LCD display screen, the display screen can be used to display a message indicative of the status information received from remote electronic system 18. For example, wherein remote electronic system 12 is a garage door opener, the LCD screen can display “Garage Door Close Signal Sent”, “Garage Door Closing”, “Garage Door Closed”, and/or “Garage Door Closing Error” in response to activation of wireless control system 12. According to an alternative embodiment, feedback to the driver of the vehicle can include audible feedback to the user of wireless control system 12. Additionally, status information may be sent via text or multimedia message to a mobile device, such as a cell phone, PDA or smartphone.
In one embodiment of the recall button method, a driver activates (e.g. presses) recall icon (button) 41 at step 92. The control circuit 30 determines whether a predetermined period of time has elapsed at step 94. If the predetermined period of time has elapsed, the recall status information has been cleared from memory and the method ends at step 102. If, on the other hand, the predetermined period has not elapsed, then control circuit 30 retrieves (recalls) the status information from memory 31 at step 96. It is understood that the predetermined period of time may be set as a default or selected by a driver of the vehicle. The recalled status information is displayed, as previously explained, at step 98. In one embodiment of the method, the method ends at step 102. In an alternative embodiment of the method, if the status information indicates that a failure occurred, the wireless control system 12 can reissue another control signal to the remote electronic system 18 at step 100. In this case, since the wireless control system 12 is no longer within range of the remote electronic system 18 using the typical RF signal, the system may utilize another type of wireless signal as readily understood. For example, the wireless control system 12 may provide a control signal to a cell phone connected thereto, which in turn may issue the control signal to remote electronic system 18. The wireless control system 12 may then monitor the status of the reissued control signal in a manner similar to that described above.
Advantageously, providing a wireless status signal to a user allows the user to have security in knowing whether the intended operation was a success. For example, where a driver pushes a button to close a garage door, the driver does not have to wait until the garage door is closed before driving away. The wireless control system 12 will indicate if any problem has occurred. This feature also increases security, as some drivers will drive away without having verified that the garage door has fully closed. Where the operation fails, the garage door will remain open for the duration until the driver returns. This system will alert the drivers that there has been a failure so that they can correct the problem. Moreover, the system allows the driver to recall that status of the selected operation at a later time in the event the driver fails to remember whether a selected operation occurred. For example, selection of the recall button (extra button, longer button hold or two quick presses of a single button) recalls whether the button was selected up to a predetermined period of time from leaving the home.
The foregoing invention has been described in accordance with the relevant legal standards, thus the description is exemplary rather than limiting in nature. Variations and modifications to the disclosed embodiment may become apparent to those skilled in the art and do come within the scope of the invention. Accordingly, the scope of legal protection afforded this invention can only be determined by studying the following claims.
