Abstract
A vehicle including an engine coupled to a transmission via a clutch, includes a fuel feed stop controller configured to stop fuel feeding to the engine when a first fuel feed stop condition is satisfied, and a clutch state detector configured to detect whether the clutch is engaged or disengaged, wherein the fuel feed stop controller is configured to resume the fuel feeding to the engine, when a second fuel feed stop condition continues to be satisfied and the clutch continues to be disengaged for a predetermined delay time from a time point when the first fuel feed stop condition is satisfied and the clutch state detector starts to detect that the clutch is disengaged.
Claims16
A vehicle including a clutch provided at a driving power transmission path from an engine to a drive wheel, comprising:
- a fuel feed stop controller configured to perform fuel feed stop control for stopping fuel feeding to the engine when a first fuel feed stop condition is satisfied;
- and
- a clutch state detector configured to detect whether the clutch is engaged or disengaged;
- wherein the fuel feed stop controller is configured to resume the fuel feeding to the engine when the clutch continues to be disengaged for a predetermined time after a time point when the clutch is disengaged under the condition that the fuel feed stop control is performed;
- and
- wherein the fuel feed stop controller is configured to continue the fuel feed stop control if the clutch returns to an engaged state before a lapse of the predetermined time after a time point when the clutch is disengaged under the condition that the fuel stop control is performed, and for so long as the first fuel stop condition is satisfied.
A fuel feed stop control method for use with a vehicle including a clutch provided at a driving power transmission path from an engine to a drive wheel, the method comprising:
- a first step of determining whether or not a first fuel feed stop condition is satisfied;
- a second step of stopping fuel feeding to the engine when it is determined that the first fuel feed stop condition is satisfied in the first step;
- a third step of resuming the fuel feeding to the engine when the first fuel feed stop condition is not satisfied in the second step;
- a fourth step of resuming the fuel feeding to the engine when the clutch continues to be disengaged for a predetermined time after a time point when the clutch is disengaged under the condition of stopping the fuel feeding to the engine in the second step;
- and
- a fifth step of returning to the first step when it is detected that the clutch is disengaged and the clutch is returned to an engaged state before a lapse of the predetermined time after the time point when the clutch is disengaged under the condition of stopping the fuel feeding to the engine in the second step.
