Abstract

Abstract An automatic vehicle starter in which a temperature sensor may sense a temperature of the engine. The vehicle starter may then remotely crank a starter motor of the vehicle. The duration of time that the starter motor is cranked will be based on the sensed temperature. In this way, a vehicle can be cranked for an appropriate amount of time without requiring any tachometer sensing operation. Also, to insure that the vehicle has been properly started, after a signal to remotely start the vehicle is transmitted, a first battery voltage is measured. Then, the ignition to the vehicle is turned on so that all turned on accessories will have power supplied thereto. A battery voltage is then again measured, this battery voltage representing the battery voltage with a load applied thereto from the turned on accessories having power supplied thereto. The vehicle is then automatically started. The battery voltage is then continuously measured and, if it determined that the battery voltage falls below a predetermined value, it will indicate that the vehicle has stalled. The vehicle can then automatically be restarted to insure proper starting or can be turned off.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 136 words
A method for starting a vehicle, comprising the steps of: generating a signal to a vehicle starter to crank a starter motor of the vehicle; determining an approximate temperature of an engine of the vehicle; measuring a first battery voltage; turning on power to an ignition and accessories in the vehicle so that all turned on accessories have power supplied thereto; measuring a second battery voltage which represents the battery voltage with a load applied thereto from the turned on accessories having power supplied thereto; starting the vehicle by cranking a starter motor in the vehicle, wherein a duration of time that the vehicle starter motor is cranked is based on the determined temperature; measuring the battery voltage continuously; and determining if the battery voltage falls below a predetermined battery voltage value indicating a stall condition.
Claim 2
Independent Claim 136 words
A method for starting a vehicle, comprising the steps of: generating a signal to a vehicle starter to crank a starter motor of the vehicle; determining an approximate temperature of an engine of the vehicle; measuring a first battery voltage; turning on power to an ignition and accessories in the vehicle so that all turned on accessories have power supplied thereto; measuring a second battery voltage which represents the battery voltage with a load applied thereto from the turned on accessories having power supplied thereto; starting the vehicle by cranking a starter motor in the vehicle, wherein a duration of time that the vehicle starter motor is cranked is based on the determined temperature; measuring the battery voltage continuously; and determining if the battery voltage falls below a predetermined battery voltage value indicating a stall condition.
Claim 3
Dependent Claim 31 words
The method for starting a vehicle according to claim 1, wherein the signal to the vehicle starter to crank the starter motor of the vehicle is generated by a remote transmitter.
Claim 4
Dependent Claim 38 words
The method for starting a vehicle according to claim 1, further comprising the step of automatically restarting the vehicle if it is determined that the battery voltage falls below the predetermined battery voltage value indicating a stall condition.
Claim 5
Dependent Claim 45 words
The method for starting a vehicle according to claim 1, further comprising the step of turning off power to the ignition and accessories of the vehicle if it is determined that the battery voltage falls below the predetermined battery voltage value indicating a stall condition.
Claim 6
Dependent Claim 31 words
The method for starting a vehicle according to claim 1, wherein the predetermined battery voltage value is equal to the measured second battery voltage plus an incremental voltage of 0.3 volts.
Claim 7
Dependent Claim 35 words
The method for starting a vehicle according to claim 1, wherein a look-up table storing cranking times for various temperatures is accessed to determine the duration of time that the vehicle starter motor is cranked.
Claim 8
Dependent Claim 32 words
The method for starting a vehicle according to claim 6, wherein the stored cranking times for various temperatures in the look-up table is adjusted based on an actual detected manual cranking time.
Claim 9
Dependent Claim 37 words
The method for remotely starting a vehicle according to claim 1, wherein the duration of time that the vehicle starter motor is cranked is further based on an elapse of time since the vehicle was last run.
Claim 10
Independent Claim 97 words
A method for starting a vehicle, comprising the steps of: generating a signal to a vehicle starter to crank a starter motor of the vehicle; measuring a first battery voltage; turning on power to an ignition and accessories in the vehicle, so that all turned on accessories have power supplied thereto; measuring a second battery voltage which will represent the battery voltage with a load applied thereto from the turned on accessories having power supplied thereto; starting the vehicle; measuring the battery voltage continuously; and determining if the battery voltage falls below a predetermined battery voltage value.
Claim 11
Independent Claim 97 words
A method for starting a vehicle, comprising the steps of: generating a signal to a vehicle starter to crank a starter motor of the vehicle; measuring a first battery voltage; turning on power to an ignition and accessories in the vehicle, so that all turned on accessories have power supplied thereto; measuring a second battery voltage which will represent the battery voltage with a load applied thereto from the turned on accessories having power supplied thereto; starting the vehicle; measuring the battery voltage continuously; and determining if the battery voltage falls below a predetermined battery voltage value.
