Abstract: A control apparatus for a vehicle, includes a condition that parking assist control not being performed as a stop condition of an internal combustion engine in automatic stop control, and prohibits automatic stop control of the automatic transmission while parking assist control is being executed.

Abstract: An idling stop control of the invention attains an auto start and an auto stop of an engine. At a time point t1, pre-set stop conditions are met to cut off a fuel supply to the engine. Preset starting conditions may be met at a time point t2 when the engine still continues rotating in a normal direction by the inertial force. In this state, the idling stop control starts cranking the engine. The preset starting conditions may be met at a time point t4 when a piston does not complete a compression cycle immediately before a stop of the engine but is pressed back by the compressed air to rotate the engine in a reverse direction. In this state, the idling stop control waits until cancellation of the reverse rotation of the engine and then starts cranking the engine. The arrangement of the invention desirably ensures a quick start of the engine, while effectively preventing an excess stress from acting on a gear mechanism, which connects a starter motor to the engine.

Abstract: A counterweight 40 attached to a crankshaft 38 has a projection 42, which is aligned with and faces an electromagnet 44 attached to a crank casing 46 when the crankshaft 38 is at a preset rotational position of ensuring good startability of an engine 22. Engine stop control starts a power supply to the electromagnet 44 to attract the projection 42 of the counterweight 40 at a timing when the projection 42 of the counterweight 40 is practically aligned with the electromagnet 44, on the condition that the revolution speed of the crankshaft 38 is lowered to or below a preset level immediately before a full stop of rotation of the crankshaft 38. This engine stop control stops the rotation of the crankshaft 38 and desirably holds the crankshaft 38 at the preset rotational position of ensuring good startability of the engine 22.

Abstract: A generator controller used in hybrid electric vehicle. The battery current is sampled and accumulated for T seconds. The obtained accumulated value is used to determine the control target of the generated power. Since the generated power is controlled according to the accumulated current of the battery which fits the battery's characteristic compared to the charged-and-discharged power, the battery's state of charge (SOC) can be more accurately controlled within the target zone. When the SOC of the battery is initially outside the target zone, the SOC is adjusted within the target zone by forcibly discharging or charging the battery. The precision of SOC control can be improved compared to when the SOC of the battery is controlled using the charged-and-discharged power.
