摘要： PROBLEM TO BE SOLVED: To inexpensively provide a configuration for engaging a pinion with a ring gear on an engine side with low noise immediately before engine rotation is reversed or is stopped when the engine is automatically stopped.
SOLUTION: A starter 11 can individually operate a pinion actuator 14 for making the pinion 13 plunge into the ring gear 23 on the engine 21 side to engage them with each other and a motor 12 for rotating the pinion 13. At automatic stop of the engine 21, every time a pulse is input to an ECU 20 from a crank angle sensor 25, angular velocity or engine speed at next pulse timing is predicted. A process of determining whether or not this pulse is a final pulse in the normal rotation based on whether or not the predicted value of the angular velocity or engine speed is a negative value is repeated. When the final pulse in the normal rotation is determined, the pinion actuator 14 is operated to make the pinion 13 plunge into the ring gear 23 on the engine 21 side and engage them with each other.

摘要： PROBLEM TO BE SOLVED: To improve restartability of an engine while fulfilling requirements for cost reduction.
SOLUTION: When a mechanical relay 24 and a switching element 25 for a motor for turning on-off current conduction to the motor 12 of a starter 11 are mounted in parallel to carry out engine stop position control that does not require a relatively large amount of current conduction to the motor 12 but requires a highly accurate control of current conduction to the motor 12, a crank angle at which engine rotation stops is controlled to a targeted stop position with high accuracy by precisely controlling current conduction to the motor 12 by controlling current conduction to the motor 12 with the switching element 25. On the other hand, when carrying out engine restart control that does not require highly accurate control of current conduction to the motor 12 but requires a relatively large amount of current conduction to the motor 12, current conduction to the motor 12 is turned on by means of the mechanical relay 24 for a motor to conduct a relatively large amount of current to the motor 12 to crank the motor surely.

摘要： PROBLEM TO BE SOLVED: To provide a two-voltage-type power unit which provides an excellent effect of reducing electricity costs through electricity-cost-reducing type generation control whereby generated power WG is adjusted according to the result of comparison between desired electricity costs CP and the generated power WG. SOLUTION: The electricity-cost-reducing type generation control whereby the generated power WG is adjusted according to the result of comparison between desired electricity costs CP determined according to battery characteristics and the electricity costs Cg required for a generator to generate power is applied to each voltage system of the two-voltage type power unit for a vehicle. Further, based on the result of comparison between the desired electricity costs CP of both voltage systems, the generated power is supplied preferentially to the system that needs the supply of generated power more than the other system. Thus, even if the systems are equipped with different kinds of batteries, the electricity-cost-reducing type generation control whereby the generated power WG is adjusted according to the result of comparison between desired electricity costs CP and the electricity costs Cg required to generate power, can be appropriately applied to both systems.

摘要： PROBLEM TO BE SOLVED: To provide a power supply for automobile capable of efficiently recovering regenerative energy when the speed of a vehicle is reduced, and supplying power to an electric load. SOLUTION: A regenerative energy generated at an alternator 2 when the speed of a vehicle is reduced is recovered with a high-performance main battery 5. A microcurrent is charged to a subbattery 6 from the main battery 5 through a DC-DC converter 11 or a relay switch 12.

The subbattery 6 supplies power along with the main battery 5 to the starter 7 when an engine temperature comes in a very low temperature zone or a high temperature zone at the start of engine.

摘要： PROBLEM TO BE SOLVED: To provide an engine starting device A for reducing emission (HC) even when a catalyst is in an inactive condition. SOLUTION: A motor used for a starter 1 has a series coil 4 and a shunt coil 6. A field current flowing in the shunt coil 6 is controlled to be reduced for variation in output characteristic between a high torque mode and a high speed rotation mode. Whether the catalyst is in an inactive condition or not is determined at starting the engine. When that it is in the inactive condition is determined, the field current in the motor is reduced to control the output characteristic of the starter 1 into the high speed rotation mode, whereby the engine can be driven in high speed rotation. Thus, an engine speed at starting is higher than in a normal condition (the catalyst is in an active condition) and so less fuel resides in an intake port or a cylinder to make the injected fuel properly contribute to combustion. As a result, emission (HC) to be released into the air is reduced even when the catalyst is in the inactive condition. COPYRIGHT: (C)2004,JPO&NCIPI
