Remote vehicle starting system
First Claim
1. A system for remotely operating one or more selected components of a vehicle, said one or more components including at least the vehicle'"'"'s engine, said system comprising:
- a portable transmitter, including;
a) means for generating a binary sequence including an address component uniquely identifying a vehicle to which said binary sequence is directed, a function component indicative of a desired operational state of each said selected component of the vehicle and a validation function component, said validation function component being constituted by said function component in a coded state;
b) means for transmitting said binary sequence as a radio frequency signal;
a controller for mounting in the vehicle, said controller including;
c) means for receiving said radio frequency signal and for deriving from said radio frequency signal said address component, said function component and said validation function component;
d) means for storing a vehicle identification code uniquely identifying the vehicle in which said controller is to be mounted;
e) means for comparing said vehicle identification code with said address component;
f) means for decoding said validation function component for generating a decoded validation function component;
g) means for comparing said function component and said decoded validation function component; and
h) means for generating a signal for interfacing with the vehicle to bring said one or more selected components of the vehicle into the desired operational state when at least the following conditions are met;
i) said address component matches said vehicle identification code; and
ii) said decoded validation function component matches said function component.

Abstract
A system for remotely starting a motor of a vehicle and also capable of operating various vehicle accessories such as alarm system, door locks, door windows, trunk latch, etc. The system comprises a portable hand-held transmitter generating a command in the form of a binary coded sequence and a controller mounted in the vehicle for operating the vehicle'"'"'s motor and accessories in dependence thereon. The system is characterized by a novel encoding scheme of the digitized sequence that prevents command misinterpretation by the controller, thereby avoiding an unintended avocation of the vehicle'"'"'s motor or another accessory.

9. An electronic remotely controlled vehicle security system, comprising:
-
a portable transmitter for generating a predetermined RF command signal; vehicle antitheft means for mounting in a vehicle, said vehicle antitheft means being capable of selectively assuming either one of an active operational state and a passive operational state, said vehicle antitheft means including; a) means for receiving said predetermined RF command signal; b) detecting means for sensing attempted intrusions in the vehicle, c) means for generating an alarm signal responsive to indication of a detected intrusion by said detecting means when said vehicle antitheft means is in an armed mode, said vehicle antitheft means being capable of assuming a disarmed mode in which said vehicle antitheft means is disabled, in said active operational state said vehicle antitheft means being responsive to said predetermined RF command signal for switching from one of said armed and disarmed modes to another of said armed and disarmed modes, in said passive operational state said vehicle antitheft means being responsive to an operation of at least one component of the vehicle for switching from one of said armed and disarmed modes to another of said armed and disarmed modes after a predetermined time interval has elapsed from said operation, said vehicle antitheft means when in said active operational state being responsive to an operation of at least one component of the vehicle for switching from said active operational state to said passive operational state. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An electronic remote starting system for use with a vehicle comprising:
-
a) an internal combustion motor; b) an electric starter motor to start-up the internal combustion motor; c) a solenoid device for establishing a driving relationship between the electric starter motor and the internal combustion motor, thereby allowing the electric starter motor to crank the internal combustion motor; d) a conductor establishing an electrical path for supplying electrical energy to the solenoid device; e) a key operated ignition switch in said electrical path; f) a safety-switch in said electrical path between the ignition switch and the solenoid device, the safety switch being responsive to a position of a shift lever of a transmission of the vehicle, when the shift lever is in a position such that the transmission establishes a driving relationship between the motor of the vehicle and a wheel thereof, the safety switch being in an opened condition to prevent actuation of the solenoid device, said electronic remote starting system comprising; i) a portable transmitter for generating a predetermined RF signal conveying a command to start a motor of the vehicle; ii) a controller for mounting on the vehicle, said controller including; a receiver for sensing said predetermined RF signal; an electrical conductor for connection to said electrical path between said ignition switch and said safety switch, said controller means for enabling energization of said solenoid device for cranking the internal combustion motor in response to reception of said predetermined RF signal by said receiver; said controller including means for sensing an electrical condition of the safety switch through an electrical pathway including said electrical conductor to preclude energization of the solenoid device when the safety switch is in the opened condition. - View Dependent Claims (17)
