Vehicle-mounted control system and method for an internal combustion engine
First Claim
1. A vehicle-mounted internal combustion engine control system, comprising:
- an inclination sensor for detecting a vehicle body inclination;
an operational state sensor for determining the operational state of a vehicle-mounted internal combustion engine; and
a cutoff mechanism for stopping the operation of the vehicle-mounted internal combustion engine in accordance with a vehicle body inclination detected by the inclination sensor and an operational state determined by the operational state sensor,wherein the cutoff mechanism is operable to stop operation of the vehicle-mounted internal combustion engine when it is judged that a time period, during which a vehicle body inclination angle detected by the inclination sensor is greater than a predetermined angle, is equal to or greater than a threshold stop time setting,wherein the threshold stop time setting depends on the operational state determined by the operational state sensor.

Abstract
A vehicle-mounted internal combustion engine controller is provided that can properly stop an internal combustion engine in accordance with an operational state no matter whether a vehicle body is inclined. The vehicle-mounted internal combustion engine controller comprises an inclination sensor for detecting vehicle body inclination; a mechanism for determining the operational state of a combustion engine; and a controller for stopping the operation of the combustion engine in accordance with a vehicle body inclination and an operational state. The cutoff mechanism stops the operation of the vehicle-mounted internal combustion engine when it is judged that a vehicle body inclination angle α detected by the inclination sensor is greater than a predetermined angle A for a greater or equal period of time as a threshold stop time T1, T2 setting, which varies with the operational state determined by the operational state sensor.

7. A method of controlling an internal combustion engine of a vehicle using a controller, the method comprising the steps of:
-
monitoring vehicle inclination data from an inclination sensor on a vehicle; detecting an operational state of the engine, based on input from sensed vehicle data; selecting a threshold time setting based on the detected operational state of the engine, wherein the threshold stop time setting varies with the detected operational state; starting a timer running when the sensed vehicle inclination detected by the inclination sensor becomes greater than a predetermined angle; and stopping operation of the internal combustion engine with a cutoff mechanism when the time period during which a vehicle body inclination angle detected by the inclination sensor is greater than a predetermined angle is equal to or greater than the selected threshold stop time setting. - View Dependent Claims (8, 9, 10, 11, 12, 13)
