- Automotive dealerships generally have a large number of vehicles for sale. Salesmen at dealerships are responsible for demonstrating vehicles to potential customers. For security, the vehicles may be either locked or otherwise protected by an electronic security system. To demonstrate a vehicle to a potential customer, salesmen must be able to unlock the car and, if necessary, disarm the security system. Vehicle security systems are responsive to remote control signals that are generated by key fob transmitters that are matched to specific receivers for each vehicle's security system. Unfortunately, it is necessary for a salesman to have a transmitter for each vehicle to produce an appropriate remote control signal for each car. If customers wish to see several vehicles or become interested in a vehicle as they are touring the dealership lot, the salesman must carry several transmitters or return to the office for each vehicle to be demonstrated.
- Some dealers avoid such problems by disabling or not arming the security systems. By doing so, the security of vehicles on the dealer's lot may be compromised during the time that the dealership is open. It is also necessary to lock and arm each vehicle at closing time to protect vehicles when the dealership is closed, or at other times when dealership employees are not authorized to access or start the vehicles.
- the security system is not armed when customers see a demonstration of a vehicle, they may not realize that the vehicle is equipped with a security system and the salesman may not demonstrate the system's features and ease of operation.

Abstract
A system and method for controlling remotely controlled components of a plurality of vehicles in response to a short range common signal emitted by a transmitter that can operate the components only during specified time periods. A transmitter can be programmed to provide a relatively long range customer signal that can operate the components at any time. The system and method are operative on a mutually exclusive basis wherein the remotely controlled components only respond to the common signal or the customer signal.
Description
- This application is a continuation of U.S. application Ser. No. 11/068,019, filed Feb. 28, 2005; which is a division of U.S. application Ser. No. 09/916,569, filed Jul. 27, 2001, now U.S. Pat. No. 6,870,458; the disclosures of which are hereby incorporated by reference in their entirety.
- 1. Field of the Invention
- The present invention relates to remote systems for automotive dealerships, and particularly to a remote system for selectively arming/disarming vehicles.
- 2. Background Art
- Automotive dealerships generally have a large number of vehicles for sale. Salesmen at dealerships are responsible for demonstrating vehicles to potential customers. For security, the vehicles may be either locked or otherwise protected by an electronic security system. To demonstrate a vehicle to a potential customer, salesmen must be able to unlock the car and, if necessary, disarm the security system. Vehicle security systems are responsive to remote control signals that are generated by key fob transmitters that are matched to specific receivers for each vehicle's security system. Unfortunately, it is necessary for a salesman to have a transmitter for each vehicle to produce an appropriate remote control signal for each car. If customers wish to see several vehicles or become interested in a vehicle as they are touring the dealership lot, the salesman must carry several transmitters or return to the office for each vehicle to be demonstrated.
- Some dealers avoid such problems by disabling or not arming the security systems. By doing so, the security of vehicles on the dealer's lot may be compromised during the time that the dealership is open. It is also necessary to lock and arm each vehicle at closing time to protect vehicles when the dealership is closed, or at other times when dealership employees are not authorized to access or start the vehicles.
- If the security system is not armed when customers see a demonstration of a vehicle, they may not realize that the vehicle is equipped with a security system and the salesman may not demonstrate the system's features and ease of operation. If the security system is not demonstrated, customers will be less likely to purchase the security system with the vehicle.
- Therefore, it would be beneficial to reduce the number of transmitters by having a common transmitter operable for controlling at least one component on any one desired vehicle on the lot. Secondly, it would be beneficial to enhance security by providing a transmitter that has a limited range so that only the vehicle nearest the transmitter is disarmed. Thirdly, it would be beneficial to further enhance security by prohibiting operation of the remotely controlled components during a programmable time period, for example, during the hours when the dealership personnel are not authorized to access the vehicles.
- As such, and in response to the potential benefits noted above, there is a need for selectively controlling vehicle components according to selectable signal transmission range and that is programmable to limit the time period of operation in order to solve the problems identified above and other problems that will be apparent to one of ordinary skill in the art in view of the attached specification and drawings.

Customer signal 16 b is programmed whenvehicle 22 is sold. When customer signal 16 b is enabled,transmitter 14 is disabled from transmitting common signal 16 a. This mutually exclusive arrangement prevents transmitters programmed with a customer signal 16 b from operating remotely controlled components onunsold vehicles 22 atdealership 12, and also prevents transmitters programmed with a common signal 16 a from operating remotely controlled components onvehicles 22 after the sale. -
Control switch 32, when actuated, causesoscillator 24 to transmitRF signal 16.Control switch 32 is typically actuated by depressing a button on the face of a key fob typeremote transmitter 14.Control switch 32 may be programmed to prohibit signal transmission when the programmable interrupt 34 is activated. Typically, programmable interrupt 34 prohibitsoscillator 24 from transmitting during programmable periods. Typically, such periods are those times during the day whendealership 12 is closed or at other times when the dealership's employees are not supposed to be able to accessvehicles 22.Timer 36 is provided for monitoring the time of day. Programmable interrupt 34 is programmed in response toprogramming signal 28.Oscillator 24,encoder 26,programming source 30,control switch 32, and programmable interrupt 34, are all powered bybattery 38. - In the embodiment of the present invention illustrated in

FIG. 5 ,component 20 is a vehicle security system that is controlled byRF signal 16.Vehicle security system 20 usually arms/disarmsvehicle 22. Whenvehicle 22 is armed, the system generally locks the vehicle doors and whenvehicle 22 is disarmed the system generally unlocks the vehicle doors. Additionally,security system 20 may include a kill switch (not shown) to inhibit starting thevehicle 22 unless theappropriate RF signal 16 is received. - In the embodiments of the present invention shown in
FIGS. 6 and 7 ,receiver 18, liketransmitter 14, receives programingsignal 28 bycable 40 or by RF signaling. In response toprogramming signal 28 andtimer 36,receiver 18 may be programmed to prohibit control ofcomponent 20 during times when the dealership employees are not authorized to accessvehicles 22.Programming signal 28 also functions to set the type of signal 16 a or 16 b thatreceiver 18 requires to controlcomponent 20. -
FIG. 8 illustrates a flow diagram of a method for arming/disarmingvehicle 22 according to one embodiment of the present invention when the system is in the dealership and responsive to common signal 16 a. Generally, atstep 110programing source 30 is configured to communicateprogramming signal 28. Atstep 112,transmitter 14 orreceiver 18 are programmed in response to signal 28. Atstep 114, the range in which oscillator 24 transmits signal 16 a may be controlled by a number of methods. Typically, the power level oftransmitter 14 is adjusted by analog or digital controls so thatonly vehicle 22 nearest in proximity totransmitter 18 receives common RF signal 16 a. Atstep 116,oscillator 24 transmits RF signal 16 a tonearest vehicle 22. Atstep 118,vehicle 22 receives signal 16 a so thatsecurity system 20 may arm/disarmvehicle 22 atstep 120 if the dealership is open. When the system is in the customer or customer signal mode 16 b,transmitter 14 orreceiver 18 are again programmed in response to signal 28.Oscillator 24 is set to the maximum allowed RF signal range but the signal transmitted is only effective for the remotely controlledcomponent 20 on the vehicle sold. - While embodiments of the present invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the present invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the present invention.
