Control system, control method, and control program for vehicle engine
First Claim
1. An engine control system comprising:
- a vehicle inclination angle detector arranged to detect an inclination of a vehicle relative to a horizontal plane;
a cumulative-duration-of-inclination detector arranged to detect a cumulative duration for which the inclination angle detected by the vehicle inclination angle detector is greater than a predetermined angle;
a rider'"'"'s operation detector arranged to detect whether or not a rider is operating the vehicle; and
an engine cut off device arranged to stop an engine of the vehicle when an overturning of the vehicle has been determined based on an output of the cumulative-duration-of-inclination detector and an output of the rider'"'"'s operation detector;
whereinthe rider'"'"'s operation detector detects at least one of throttle opening, pressure within an intake pipe, braking, or braking and shifting of the vehicle responsive to rider'"'"'s operation; and
the output of the rider'"'"'s operation detector includes an output of the at least one of the throttle opening, the pressure within an intake pipe, the braking, and the braking and shifting of the vehicle detected by the rider'"'"'s operation detector.

Abstract
An engine control system correctly determines when a vehicle overturns and includes a vehicle inclination angle detector arranged to detect an inclination of a vehicle relative to a horizontal plane, a cumulative-duration-of-inclination detector arranged to detect a cumulative duration for which an inclination angle detected by the vehicle inclination angle detector is greater than a predetermined angle, a rider'"'"'s operation detector arranged to detect whether or not a rider is operating the vehicle, and an engine cut off device arranged to stop an engine of the vehicle when it has been determined that the vehicle has overturned, based on an output of the cumulative-duration-of-inclination detector indicating the cumulative duration for which the inclination angle detected by the vehicle inclination angle detector is greater than the predetermined angle, and an output of the rider'"'"'s operation detector indicating that the rider is operating the vehicle.

5. An engine control system comprising:
-
a vehicle inclination angle detector arranged to detect an inclination of a vehicle relative to a horizontal plane; a first cumulative-duration-of-inclination detector arranged to detect a first cumulative duration for which the inclination angle detected by the vehicle inclination angle detector is greater than a predetermined angle; a second cumulative-duration-of-inclination detector arranged to detect a second cumulative duration that is set to be longer than the first cumulative duration; a rider'"'"'s operation detector arranged to detect whether or not a rider is operating the vehicle; a first engine cutoff device arranged to stop an engine of the vehicle when an overturning of the vehicle has been determined based on an output of the first cumulative-duration-of-inclination detector and an output of the rider'"'"'s operation detector; and a second engine cutoff device arranged to stop the engine of the vehicle when an overturning of the vehicle has been determined based on an output of the second cumulative-duration-of-inclination detector. - View Dependent Claims (6, 7, 8, 9)

10. An engine control method comprising the steps of:
-
detecting an inclination angle of a vehicle; detecting a cumulative duration for which the inclination angle is greater than a predetermined angle; detecting whether or not a rider is operating the vehicle; and stopping an engine of the vehicle when an overturning of the vehicle has been determined based on an output indicating the cumulative duration and an output indicating whether or not the rider is operating the vehicle;
whereinthe step of detecting whether or not a rider is operating the vehicle includes detecting at least one of throttle opening, pressure within an intake pipe, braking, or braking and shifting of the vehicle responsive to rider'"'"'s operation; and in the step of stopping the engine of the vehicle, the output indicating whether or not the rider is operating the vehicle includes an output of the at least one of the throttle opening, the pressure within an intake pipe, the braking, and the braking and shifting of the vehicle detected in the step of detecting whether or not the rider is operating the vehicle. - View Dependent Claims (11, 12, 13)

14. An engine control method comprising the steps of:
-
detecting an inclination angle of a vehicle; detecting a first cumulative duration for which the inclination angle is greater than a predetermined angle; detecting a second cumulative duration for which the inclination angle is greater than a predetermined angle and that is set to be longer than the first cumulative duration; detecting whether or not a rider is operating the vehicle; stopping an engine of the vehicle when an overturning of the vehicle has been determined based on the first cumulative duration and an output indicating whether the rider is operating the vehicle; and stopping the engine of the vehicle when an overturning of the vehicle has been detected based on an output indicating the second cumulative duration of inclination. - View Dependent Claims (15, 16, 17, 18)
