Abstract
An engine controller is proposed which facilitates an operation at start of a vehicle without forcing mental strain to a rider to cancel start control. An engine controller includes a start determinator for determining start of a vehicle, an elapsed time after start timer for counting elapsed time Tp since start of the vehicle is determined by the start determinator, and a start controller for adjusting an output of an engine until the elapsed time Tp counted by the elapsed time after start timer reaches a predetermined control time Tr determined in advance if the start of the vehicle is determined by the start determinator.
Claims7
An engine controller for a vehicle, the engine controller comprising:
- a start determinator for determining whether or not the vehicle has been started;
- an elapsed time after start timer for measuring elapsed time since start of the vehicle determined by the start determinator;
- and
- a start controller for adjusting an engine output until the elapsed time measured by the elapsed time after start timer reaches a pre-determined control time in response to the start determinator determining that the vehicle has been started,
- wherein the start determinator determines whether the vehicle has started in response to determining whether a drop rate of the engine rotation speed is larger than a pre-determined drop rate, and
- wherein the start determinator suppresses the start determination of the vehicle in response to a determination that the engine rotation speed has reached or is over a pre-determined upper limit rotation speed.
