Snowmobile remote ignition system
First Claim
1. A snowmobile having an engine, a drive train driven by the engine, and a remote starting system, the remote starting system comprising:
- a remote starting activation switch that transmits a radio frequency signal to a remote starter module to initiate starting the engine, the remote starter module receiving the radio frequency signal from the remote starting activation switch and, in response to receiving the radio frequency signal, causing a starter motor of the snowmobile to crank and start the engine;
a motion sensor for sensing motion of a component of the drive train; and
wherein the remote starter module interrupts engine operation upon sensing motion of the drive train component, if insertion of a key into an ignition switch of the snowmobile and the key being turned to an on or run position are not detected.

Abstract
Herein is disclosed a snowmobile configured to start in response to a remote-start signal. One embodiment of the invention includes a snowmobile outfitted with a remote starting system. The remote starting system, itself, includes a remote starting activation switch that transmits a radio frequency signal to a remote starter module to initiate starting of an engine within the snowmobile. The remote starter module receives the radio frequency signal from the remote starting activation switch and, in response to receiving the radio frequency signal, initiates closure of a switch interposed between a battery and a starter motor, thereby causing the starter motor to crank and start the engine of the snowmobile. The engine may be shut off by the remote starting system if the engine RPM exceeds a threshold value.

12. A method of controlling on/off operation of a snowmobile from a remote location, the method comprising:
-
transmitting a radio frequency signal to a remote starter module of the snowmobile to initiate starting of the engine; activating a starter motor of the snowmobile with the remote starter module to crank and start the engine; determining if a driver authorization condition is detected;
determining an engine RPM using a frequency of an alternator signal from an alternator of the engine;determining whether the engine RPM exceeds an RPM threshold level; and interrupting engine operation of the snowmobile if the driver authorization condition is not detected and the engine RPM exceeds the RPM threshold level. - View Dependent Claims (13, 14, 15, 16)
