Abstract: PROBLEM TO BE SOLVED: To provide a vehicle control technique capable of suppressing operation of an internal combustion engine in an operation state with a high fuel consumption rate even when a vehicle start cornering during acceleration and coasting travel.
SOLUTION: An HVECU 100 makes a vehicle 1 perform acceleration and coasting travel by repeating acceleration travel in which an internal combustion engine 10 is brought into an operation state to drive the vehicle 1 by driving force and coasting travel in which the engine 10 is brought into an non-operation state to drive the vehicle 1 by coasting force between preset upper and lower limit vehicle speeds. When determining that the vehicle 1 is cornering during acceleration travel, the HVECU 100 stops the acceleration travel, lowers the driving force in comparison to the case where the acceleration travel is not stopped in the cornering, and also makes a motor MG1 operate as a power generator to convert kinetic energy by the lowering of the driving force into charging electric power.

SOLUTION: Power circulation is avoided by stopping rotation of a motor generator with engagement of a brake to be fixed (S103, S104), when a rotation speed Ng of the motor generator is negative (direction reverse to a rotational direction of an engine). A required rotation speed Ng0 of the motor generator is calculated under a high efficiency condition where a speed Ne of an engine 50 is consistent with the required rotation speed Ng0 on an optimum fuel consumption line (S106), when the brake is engaged, and the brake is released to release the rotation speed of the motor generator (S107, S108), when the required rotation speed Ng0 is a positive prescribed value Ng1 or more (direction same to the direction of the rotational direction of the engine).

Abstract: PROBLEM TO BE SOLVED: To smoothly start on an ascending sloped road, and to cope with the situation where smooth starting cannot be made. SOLUTION: Braking for front wheels output with power from an engine is released, under conditions where braking for rear wheels is held (S140), and a throttle opening TH is made large gradually, to bring an engine speed into a target speed Ne* corresponding to a road face slope θ(S180), when a driver returns a brake pedal on an up-hill sloped road. Braking for the rear wheels is released (S240), when an output torque Tem output to the front wheels and the rear wheels gets larger than a target torque Td*, corresponding to the road face slope θ, to start. The start is smoothed thereby on the ascending sloped road. The braking for the front wheels is returned to an original state to inhibit ascending sloped road start control (S260, S270), when the slippage of the front wheels is determined before the output torque Tem comes to the target torque Td*, and a stoppage condition is held, so as to cope with even the situation that does not allow smooth start.

Abstract: PROBLEM TO BE SOLVED: To more certainly perform fuel injection into a cylinder stopping within a predetermined scope at the time of stopping an internal combustion engine, and to more quickly start the internal combustion engine.
SOLUTION: In the internal combustion engine, when a stop angle CAs1 of the cylinder where fuel injection is performed is outside the fuel injection stopping scope (CA1 to CA2) which is able to burn at the starting, a fuel injection starting rotational speed Nref1 which is an engine rotational speed permitting the fuel injection at the engine stop is reduced to adjust, and a fuel injection stop rotational number Nref2 which is an engine rotational speed re-prohibiting the fuel injection is increased to adjust (S210 to S230). When a stop angle CAs2 of the cylinder not performing the fuel injection is within the fuel injection stop scope, the fuel injection starting rotational speed Nref1 is increased to adjust, and the fuel injection stop rotational number Nref2 is reduced to adjust (S240 to S260). Thereby, the fuel injection can be certainly performed by the cylinder stopping in the scope of the fuel injection stop.

Abstract: PROBLEM TO BE SOLVED: To more promptly start an internal combustion engine and suppress disadvantages caused by unburned fuel injected beforehand at the time of stop of the internal combustion engine.
SOLUTION: When engine speed Ne reaches fuel injection start speed Nref1, if a shift position SP is a position capable of running, fuel injection is permitted, and fuel injection is performed before the engine is stopped, with respect to a cylinder stopped within a fuel injection stop range from an intake stroke to a compression stroke at the time of stop of the engine (S150). If the shift position SP is a position incapable of running, fuel injection beforehand with respect to the cylinder stopped within the fuel injection stop range is prohibited (S140, S190). Due to this, next start of the engine can be promptly performed, and disadvantages caused by stop of the engine for relatively long time with injected fuel unburned can be avoided.
