Remote control system with time limited operability
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.

BACKGROUND OF THE INVENTION1. 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.
SUMMARY OF THE INVENTIONThe present invention provides systems for remotely controlling components of automotive vehicles during selected time periods.
According to one aspect of the present invention, a security system for a vehicle is provided. The security system includes a transmitter and a programming tool. The transmitter has an interrupt programmable in a first mode to permit the transmitter to communicate with a receiver of the vehicle and in a second mode to inhibit the transmitter from communicating with the receiver. The programming tool is separate from the transmitter and is configured to generate a programming signal for the interrupt. The programming signal has information setting an authorized time period in which the interrupt is programmed in the first mode to permit the transmitter to communicate with the receiver during the authorized time period and information setting an unauthorized time period in which the interrupt is programmed in the second mode to inhibit the transmitter from communicating with the receiver during the unauthorized time period.
The unauthorized time period may correspond to a time period in which the vehicle is not intended to be operated whereas the authorized time period may correspond to a time period in which the vehicle is intended to be operated. The transmitter may be operable to communicate with a single receiver or a set of receivers disposed on different vehicles while the interrupt is programmed in the first mode.

The time period may correspond to a time of day when the transmitter is to be inhibited from transmitting the command signal. The security system may further include a programmable encoder for programming the command signal. The command signal may be a radio frequency (RF) command signal. The transmitter may be adjustable to select a transmission range, such as approximately four to six feet, for the command signal. The programming device may include a computer.
According to another aspect of the present invention, a remote control system is provided. The remote control system includes a programming device and a transmitter.

BRIEF DESCRIPTION OF THE DRAWINGS
Dealership 12 includes a number of vehicles 22 spaced apart from one another in a typical parking lot spacing of four to six feet. Vehicle 22 is provided with the receiver 18 and at least one remotely controlled component 20. Remotely controlled component 20 may be a security system, door lock, lighting system, air conditioning system, vehicle seats, heating system, engine starter, or the like. At least one of the components 20 is responsive to RF signal 16.
Encoder 26 programs RF oscillator 24 according to instructions contained in a programming signal 28. Programming source 30, which is typically a computer, provides and transmits programming signal 28. Programming source 30 is shown in the embodiment of
In response to programming signal 28, encoder 26 may be adjusted so that either the common signal 16a or customer signal 16b is transmitted by oscillator 24. Common signal 16a is a short range signal that serves as a master key for all vehicles on the dealership lot that are equipped with the system. Customer signal 16b is programmed when vehicle 22 is sold. When customer signal 16b is enabled, transmitter 14 is disabled from transmitting common signal 16a. This mutually exclusive arrangement prevents transmitters programmed with a customer signal 16b from operating remotely controlled components on unsold vehicles 22 at dealership 12, and also prevents transmitters programmed with a common signal 16a from operating remotely controlled components on vehicles 22 after the sale.
Control switch 32, when actuated, causes oscillator 24 to transmit RF signal 16. Control switch 32 is typically actuated by depressing a button on the face of a key fob type remote transmitter 14. Control switch 32 may be programmed to prohibit signal transmission when the programmable interrupt 34 is activated. Typically, programmable interrupt 34 prohibits oscillator 24 from transmitting during programmable periods. Typically, such periods are those times during the day when dealership 12 is closed or at other times when the dealership's employees are not supposed to be able to access vehicles 22. Timer 36 is provided for monitoring the time of day. Programmable interrupt 34 is programmed in response to programming signal 28. Oscillator 24, encoder 26, programming source 30, control switch 32, and programmable interrupt 34, are all powered by battery 38.

Upon receiving one of the signals 16a or 16b, the system functions to control at least one component 20.
