摘要： PROBLEM TO BE SOLVED: To provide a control device for a vehicle that is made compatible in both the suppression of the lowering of drivability and the prevention of an engine stall.SOLUTION: An ECU increases an engine rotation speed (step S14) when an ECU determines that an inclination angle of an uphill is larger than or equal to a predetermined value (step S11: Yes), an accelerator is turned off (step S12: Yes) and a vehicle speed in a direction opposite to a travelling direction of a vehicle indicated by a specified range is increased (step S13: Yes). Subsequently, the ECU 10 acquires an engine stall predicted vehicle speed Vpred, and calculates a predetermined value B used in an immediate engine stall determination condition from a current rate of an increase per unit time of a turbine rotation speed (step S15). Then, the ECU determines that immediate engine stall determination is affirmative when a rotation speed difference between the engine rotation speed and the turbine rotation speed becomes lower than the predetermined value B (step S16: Yes), and executes engine stall prevention control (step S17).

摘要： PROBLEM TO BE SOLVED: To provide a controller of a multi-cylinder internal combustion engine capable of autonormaouly resuming engine operation with suppressing execution of waste fuel injection. SOLUTION: The controller of the multi-cylinder internal combustion engine stops fuel injection to automatically stop the engine operation when an automatically stopping demand is made. Besides, when a starting demand is made, based on the automatically stopping demand, during a term from a time point the fuel injection is stopped to that the engine operation is completely stopped, the controller calculates the residual torque of the engine based on an engine operating status at that time. Further, it is judged, based on the residual torque TR, whether or not a cylinder #N first making the transition to an intake stroke after the starting demand is made can make the transition to a compression stroke till the engine operation is completely stopped. Furthermore, when it is judged that the cylinder #N can make the transition to the compression stroke, fuel injection is started from the intake stroke of the cylinder #N, while when being judged to be unable to be transferred to the transition, a starter motor 4 is activated and at the same time the fuel injection is executed.

摘要： PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine, performing automatic start processing according to a crank angle at an automatic stop when requirements for restart are satisfied, and quickly manually restarting an internal combustion engine even if the automatic restart is disabled. SOLUTION: This electronic control device 60 automatically stops the internal combustion engine 1 when the requirements for stop are satisfied during the operation of the engine. The control device stores the crank angle at which the engine stops, in a memory 61.

The electronic control device 60 performs a normal start processing by invalidating the automatic start processing when a main switch 71 is operated to a "START" position by the time when the requirements for restart are satisfied after the internal combustion engine 1 is automatically stopped.
