A microprocessor based system for remote starting of an automobile engine includes circuitry for automatically actuating an accelerator of the automobile to effect starting of the engine, circuitry for energizing the starter motor for a predetermined number of seconds, repeating energizing of the engine a predetermined number of times if the engine does not start, and providing a predetermined delay between each energizing of the automobile engine. A remote transmitter transmits a start command to a receiver located in the automobile, causing the receiver to cause an algorithm stored in the microprocessor to attempt to start the engine and control certain accessories. A fail-safe accessory control algorithm stored in the microprocessor system effects energizing and de-energizing accessory control motors in accordance with signals from position sensors which detect positions of moveable components of an accessory and effects de-energizing the accessory control motor after a predetermined number of seconds if a position sensor signal does not indicate that the accessory component being moved has actuated a position sensor.

A system for automatically starting an engine of an automobile in response to a start command, said system comprising in combination: (a) command means for entering said start command into said automatic starting system; (b) status means for producing an engine status signal if said engine is runnin

A system for automatically starting an engine of an automobile in response to a start command, said system comprising in combination: (a) command means for entering said start command into said automatic starting system; (b) status means for producing an engine status signal if said engine is running; (c) means responsive to a first control signal for energizing a starter motor of said automobile; (d) first control means responsive to said command means for generating said first control signal, thereby causing said energizing means to energize said starter motor, said first control means including; (i) means coupled to said command means for enabling said first control means to generate said first control signal in response to said start command if said engine status signal is not present; (ii) first timing means for producing a first timing signal a first predetermined time after said first control signal is generated; (iii) means responsive to said first timing signal and said engine status signal for stopping said first control signal, thereby de-energizing said starter motor if said engine is not running after said first predetermined time; (iv) second control means responsive to said first timing signal for enabling said first control means to generate said first control signal a predetermined number of times in response to said start command if said engine status signal is not present after said first predetermined time has elapsed; (v) counting means for counting a number of times said first control signal is generated in order to determine the number of attempts made by said start command, wherein said enabling of said first control means by said second control means is conditioned upon said number of attempts being less than said predetermined number; (e) means for pumping said accelerator in response to a second control signal wherein said first control means further includes means for generating said second control signal to cause said accelerator pumping means to pump said accelerator; wherein said first control means further includes second timing means for producing a second timing signal a second predetermined amount of time after said stopping of said first control signal, said second control means being also responsive to said second timing signal, said second means causing said first control means to generate said first control signal if said engine is not running, said number of times is less than a predetermined number, and said second predetermfined amount of time has elapsed after said stopping of said first control signal; and (f) a remote transmitter located externally of said automobile, a receiver located in said automobile and coupled to said start command entering means, and remote start command entering means connected to said remote transmitter for causing said remote transmitter to transmit said start command to said receiver, said receiver including means for detecting said transmitted start command and entering said transmitted start command to said system; whereby, said first control means attempts to restart said engine a plurality of times in response to said start command if the earlier attempts fail to start said engine in response to said start command.
