Control apparatus for internal combustion engine
View Patent ↗In an apparatus for controlling an internal combustion engine mounted on a vehicle, it is configured to have a falling signal generator that generates a falling signal indicative of falling of the vehicle when the vehicle falls; an operation stopper that stops operation of the engine in response to the generated falling signal; and a suspender that suspends processing of the operation stopper to stop the operation of the engine until a predetermined time period elapses. With this, when the falling of the vehicle is not serious and the operator lifts the vehicle body within the predetermined time period, the operator can restart the vehicle to drive immediately after lifting the vehicle body.
1. An apparatus for controlling an internal combustion engine mounted on a vehicle, comprising:
a falling signal generator that generates a falling signal indicative of falling of the vehicle when the vehicle falls;
an operation stopper that stops operation of the engine in response to the generated falling signal;
a suspender that suspends processing of the operation stopper to stop the operation of the engine until a predetermined time period elapses; and
an engine speed detector that detects speed of the engine;
wherein the suspender sets the predetermined time period to decrease with increasing of the detected engine speed.
2. An apparatus for controlling an internal combustion engine mounted on a vehicle, comprising:
a falling signal generator that generates a falling signal indicative of falling of the vehicle when the vehicle falls;
an operation stopper that stops operation of the engine in response to the generated falling signal;
a suspender that suspends processing of the operation stopper to stop the operation of the engine until a predetermined time period elapses; and
a vehicle condition determiner that determines whether the vehicle is in a predetermined condition in which the operation of the engine should be stopped,
wherein the operation stopper stops the operation of the engine when the vehicle is determined to be in the predetermined condition before the predetermined time period elapses.
3. The apparatus according to claim 2 , further including:
a throttle opening detector that detects throttle opening of a throttle valve of the engine, and
the vehicle condition determiner determines that the vehicle is in the predetermined condition when the detected throttle opening is equal to or greater than a predetermined throttle opening.
4. The apparatus according to claim 3 , further including:
a transmission that varies an output of the engine in rotational speed;
a speed ratio detector that detects a speed ratio of the transmission, and
the vehicle condition determiner determines that the vehicle is in the predetermined condition when the detected speed ratio is equal to or less than a predetermined value.
5. The apparatus according to claim 2 , further including:
a transmission that varies an output of the engine in rotational speed;
a speed ratio detector that detects a speed ratio of the transmission, and
the vehicle condition determiner determines that the vehicle is in the predetermined condition when the detected speed ratio is equal to or less than a predetermined value.
6. The apparatus according to claim 5 , further including:
a clutch that is interposed between the engine and the transmission to transmit the output of the engine when being engaged;
a clutch engagement determiner that determines whether the clutch is engaged, and
the vehicle condition determiner determines that the vehicle is in the predetermined condition when the clutch is determined to be engaged and the detected speed ratio is equal to or less than the predetermined value.
