METHOD AND SYSTEM FOR VEHICLE ROLLOVER ENGINE PROTECTION, EMERGENCY CALL AND LOCATION SERVICES
First Claim
1. A vehicle rollover engine protection system for a vehicle including an engine, comprising:
- an inertial sensor unit for sensing rollover of the vehicle;
a fuel injection control;
a fuel pump control;
an electronic control unit including a processor and a memory; and
a communication bus for providing communication from the inertial sensor unit to the electronic control unit, and for providing communication between the electronic control unit and each of the fuel injection control and the fuel pump control,wherein, when the electronic control unit receives an inertial sensor unit signal indicating that a vehicle rollover has occurred, the processor of the electronic control unit is configured to;
close fuel injectors to cut-off fuel to the engine of the vehicle with the fuel injection control, andstop operation of a fuel pump of the engine with the fuel pump control.

Abstract
A vehicle rollover engine protection and location system 10 for an off-road vehicle includes an inertial sensor unit 22, a communication bus 18 for providing communication from both the rollover sensor 22 and a global positioning system 40 to an electronic control unit 12. When a vehicle rollover has occurred, a processor 14 of the electronic control unit 12 is configured to stop providing fuel to an engine of the off-road vehicle, stop operation of the fuel pump, determine a location of the off-road vehicle from signals of the global positioning system, perform a rollover emergency call to actively indicate rollover of the off-road vehicle, and transmit a location signal.
