REMOTE STARTING DEVICE FORNMOTOR VEHICLES Filed April V25, 1967 ATTORNEY United States Patent O 3,455,403 REMOTE STARTING DEVICE FOR MOTOR VEHICLES Vernon D. Hawthorne, Raleigh, N.C., assigner of fifty percent to James Finley Boney, Raleigh, N.C. Filed Apr. 25, 1967, Ser. No. 633,480 Int. Cl. B60k 27/02, 33/02; B601' 18/00 U.S. Cl. 180-1 8 Claims ABSTRACT OF THE DISCLOSURE This invention relates to engine starting devices and more particularly to a system for remotely starting of the engine of a vehicle and operation of accessory items.
In the past, various types of remote control starting devices have been developed using such things as photoelectric cells and mechanical contact between a portion of the vehicle to be started and a contact connected to a remote control. All of these systems, however, have been extremely costly in construction and installation as Well as being limited to a single starting location due to the permanently fixed remote control station. The prior art devices further are inadequate in that there is no positive control of accessory equipment such as heaters and air conditioners. There have also been developed many types of automatic starting devices utilizing a clock or similar timer. This has the obvious disadvantage of forcing the operator of the vehicle to determine many hours in advance the exact time he wishes the engine to start with no remote means for changing the time should that originally set become inconvenient or undesirable.
The present invention has been developed after much research and study into the above mentioned problems s and is designed to provide an improved portable remote control system for motor vehicles having a dependable starting means which substantially duplicates manual starting procedures. The device also keeps the operator informed as to whether the engine of the vehicle is operating and incorporates a means for preventing unauthorized movement of the vehicle should the running engine thereof become tempting to indiscreet persons. Since one of the main reasons for remotedly starting vehicle engines is to warm up the engine so that the vehicle will be ready to go almost instantaneously, a means has also been provided for remotedly controlling the climatic conditioning of the interior of the vehicle by allowing control of both the heater and air conditioner units. To further overcome the difficulties presented by the prior art devices. Applicant has developed a system which is simple to operate and install in the vehicle as well as being completely portable thereby eliminating the limiting features of xed remote units. This has a definite advantage of allowing the remote starting device to be used from a motel or hotel room or any other location where the operator may wish to start his vehicle without entering it.
It is, therefore, an object of the present invention to provide an improved, combined remotely controlled engine starting system `and accessory control system which substantially duplicates the manual operation of these units.
Another object of the present invention is to provide, in combination with an improved remote control startice ing system, an indication means for informing the operator of the functioning condition of the engine.
A further object of the present invention is to provide a means for preventing unauthorized movement of a vehicle which is standing unattended with its engine running.
Another object of the present invention is to provide a remote control means for climatically conditioning the interior of a vehicle.
Another object of the present invention is to provide a remote control starting and operating system for a motor vehicle which is completely portable for both the vehicle unit and the remote control unit.
Other objects and advantages of the present invention will become apparent and obvious from a study of the following description and the accompanying drawing which are merely illustrative of the present invention.
In the drawing:
The single figure is a circuit diagram of a preferred embodiment of the remote control system of the present invention.
With further reference to the drawing, FIG. 1 discloses a remote control system for a motor vehicle including an electrical power source such as a battery 10 which is connected through junction 11 to both ignition switch 12 and relay 13.
The ignition switch is so constructed as to energize the primary electrical circuit 14 of the vehicle and the starter motor 15 when operated manually as indicated by the irregular broken lines.
Switch 12 and relay 13 are connected in such a manner that when said switch is in the oif position, the circuit is made through the relay and when said switch is in the on position, the circuit through the relay is broken. When relay 13 is closed, electricity can flow through the relay to shift lever switch 16. This switch is so constructed that the circuit therethrough is made only when the vehicle is in park. Whenever the gear shift lever is moved to any other position, the shift switch is opened thereby interrupting the ow of current therethrough.
A vehicle transceiver 17 such as a combined transmitter and receiver of the type commonly used to control model airplanes, ships, cars and the like is connected to shift switch 16. Connected to transceiver 17, in such a manner that upon the receipt of the proper signal they may be turned on or oit, are throttle actuator 18, air conditioner 19, heater Z0, primary circuit 14 and start r motor 15.
An oil pressure sensing switch is placed in a circuit extending from the vehicle transceiver through such switch and back to the transceiver. This switch is so designed that it will be closed only upon the reaching of a predetermined amount of oil pressure within the engine thereby allowing current to ow therethrough and at pressure below the predetermined amount it will remain open thereby preventing current flow.
As will be noted from the ligure, the circuit through the starter motor 15, throttle actuator 18, airconditioner 19 and heater 20 are all completed through a common ground which is connected to one side of the current source or battery 10. In actual practice of the present invention, all the lead in and outlet connections could be built into a single multipronged plug so that the transceiver 17 may be plugged thereinto. If preferred, a multiwire, pigtail type connection could be connected to the unit. In either case, the transceiver would be readily removable for repairs or transferred to another vehicle which is similarly wired. It is also contemplated that the overall system of the present invention could be either preinstalled at the factory as the car is being built or could be later installed by the owner.
In actual operation of the remote control device of the present invention, remote transceiver 22 (of the same ltype as transceiver 17) is portably placed in a desired location within transmission and receiving range of the vehicle transceiver 17. When the operator decides to start the engine of the vehicle, he can actuate switch 23 of transceiver 22 which sends a signal to transceiver 17 which in turn allows current to ilow from .battery to throttle actuator 18 thereby opening the throttle of the engine (not shown). If a pumping effect is desired similar to pumping the accelerator pedal to prime a cold engine, switch 23 may be moved from on to off position several times. Next, switch 28 of the remote transceiver is used Y to close the circuit in vehicle transceiver 17 to energize the overall primary electrical system 14 including the ignition system (not shown). When this is done, switch v24 of transceiver 22 is actuated so as to transmit a. signal to transceiver 17 which closes the circuit from battery 10 to starter motor 15. As this motor turns, the engine will start thereby building up oil pressure within the crank `case thereof. Since this build-up of oil pressure is relatively rapid, and since in most automotive vehicles the starter motor disengagement is automatic upon the starting of the engine, as soon as oil pressure of a predetermined amount is reached a circuit through oil pressure sensing switch 21 'will be completed from the transceiver 17 through the switch and back thereto which automatically opens the circuits from battery 10 to starter motor and throttle actuator 18. The closing of the circuit through the oil pressure sensing switch also activates the transmitter portion of vehicle transceiver 17 thereby sending a signal to the receiver portion of remote transceiver 22 which in turn lights indicator 25 to show the operator that the engine is running.
Thus it can be seen that the manual starting procedures for the vehicle engine may be duplicated from a remote position including informing of the operator of the remote device that the engine is running.
Either immediately after the starting process or at a later time after the engine has had time to warm up and run smoothly, the heater or air conditioner 19 may be selectively turned on by manipulation of remote transceiver heater switch 26 or air conditioner switch 27. The delayed manipulation of either of these two accessories is usually desirable since in the winter the heater is not usually turned on until the engine has warmed up and the air conditioner would not be turned on in the summer until the engine is running smoothly due to the additional load placed on the engine by the engagement of the refrigeration system compressor.
Since the operation of the heater and air conditioner is directly from the battery 10 by way of transceiver 17, y
the overall automobile primary circuit 14 through which these two units usually operate does not necessarily have to be on. Should some of the other accessories in the vehicle which are connected to the circuit be desired to operate such as the radio, stereo, windshield wipers, etc., switch 23 must be -manipulated to send a signal to transceiver 17 to energize the system.
After the engine of the vehicle has been started and warmed up and the heater or air conditioner, as the case may be, has been operating long enough to climatically control the temperature within the vehicle, the operator may drive the vehicle in the normal manner by inserting a key into ignition switch 12 and turning the same to the on position which will automatically open the circuit through relay 13 thereby rendering transceiver 17 and all systems connected thereto inoperative while at the same time closing the circuit indicated by the irregular broken lines to primary circuit 14 which is in turn connected to the heater 20, air conditioner 19 and the other accessory equipment (not shown) of the vehicle as well as to the engine ignition system. Thus it can be seen that by turning the ignition switch to the on position, immediate shift from the remote control system to the normal manual system of the vehicle is possible. If desired, a reset switch (not shown) may be provided in vehicle transceiver 17 so that once the ignition switch 12 has been manipulated, the vtransceiver cannot be reactivated until reset manually. Likewise, it is obvious that once the ignition switch has been turned to the on position, should the engine for some reason stall or stop, the starter motor 15 may be activated to restart the engine, as shown by the irregular broken lines connecting switch 12 and motor 15, without having to go through the vehicle transceiver 17.
The throttle actuator 18 may be either an electromagnetic type device or any other desired electrical means to accomplish the end result. It should be noted that it is not necessary to in any way connect this -device through thef'primary circuit system since it is only used when thevehicle is on remote control. Likewise, the oil pressure sensing switch is only used during automatic operation although it, of course, could have either an automatic pressure gage or an indicator light connected thereto so that it would serve the dual purpose of circuit control and indicator.
Should the operator of the Vehicle inadvertently forget to insert the ignition key into ignition switch 12 or should some unauthorized person attempt to drive the carv by placing the gear shift lever in the drive position, the circuit between relay 13 and vehicle transceiver 17 would be interrupted thereby automatically cutting olf the vehicle engine by interrupting the ow of current to primary circuit 14 to which the engine ignition system, as hereinabove described, is attached. This feature of the system not only will prevent thefts of the vehicle but should allow the running of the engine unattended without in fracting the laws in certain metropolitan areas which prohibit the leaving of a vehicle unattended while the engine is running since the vehicle would be attended, at least technically, from a remote position.
In place of the oil pressure sensing switch 21 could be substituted either a manifold pressure sensing switch, a temperature sensing switch preferably connected to the cylinder head or cylinder wall, an electrical surge sensing switch connected to the generator or alternator or a RPM sensing switch such as a tachometer since any of these means could serve the purpose of sensing the fact that theengine has started.
'If the vehicle to which the remote system of the present invention is connected does not have an automatic choke device connected to the throttle, a choke could be connected from vehicle transceiver 17 to operate similar to throttle actuator 18. This choke device could also be so connected that it would not automatically cut olf as throttle actuator 18 does upon the starting of the engine, but could be maintained in choke position until cut off or reduced from a switch (not shown) on remote transceiver 22.
It is obvious that the present invention has the advantages of providing a simplified remote operation system for vehicular type machines which is inexpensive to install and operate and which substantially duplicates the manual operation of the various systems from a remote position. The system of the present invention likewise has the advantage of allowing the remote transceiver to be transported to various locations without any specific oprational relationship except to be within the predetermined transmitting and receiving range of the vehicle unit.
The present invention may, of course, be carried out in other specic ways than those herein set forth without departing from the spirit and essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive and all changes coming within the meaning and equivalency range are intended to be embraced herein.
