摘要:
A state estimation value indicating a battery state is successively calculated from time to time according to a battery model capable of dynamically estimating the internal state of the secondary battery by using an inspection value of a sensor group indicating the secondary battery behavior. By using the sate estimation value at each moment estimated by the battery model expression at each predetermined cycle (Tc), an I/O-enabled time is predicted when a predetermined power is continuously inputted (charged) or outputted (discharged) from the current moment. A load operation instruction of the secondary battery is set so as to avoid overcharge and over-discharge of the secondary battery according to the operation request to the load and by considering the predicted characteristics between input/output power and input/output-allowed time.

Provided is a dog clutch actuator comprising a sleeve (10) having dog teeth made engageable with the dog teeth formed in a power transmission shaft (30) and made movable in the axial direction, and a plunger (14) for moving together with the sleeve(10). The plunger (14) is axially moved through a yoke (16) by electric currents to flow through coils (18 and 20). The dog clutch actuator is so characterized by the shapes of the plunger (14) and the yoke (16) that a sucking force increases in the engaging direction, when the dog clutch is engaged, and decreases in the disengaging direction, when the dog clutch is disengaged.

A driving device of the invention has a clutch 40 and a continuously variable transmission 50. The clutch 40 couples and decouples a rotating shaft 24 or an output shaft of a motor 30 with and from a driveshaft 22. The continuously variable transmission 50 has an input shaft connected to the rotating shaft 24 and an output shaft connected to the driveshaft 22 via a gear mechanism 52. A spring 36 is attached to a rotor 31 of the motor 30 to apply a pressing force and cause the clutch 40 to couple the rotating shaft 24 with the driveshaft 22 in response to a relatively small output torque of the motor 30. With an increase in output torque of the motor 30, a thrust force produced in the motor 30 moves the rotating shaft 24 against the pressing force of the spring 36 to cause the clutch 40 to decouple the rotating shaft 24 from the driveshaft 22. The output torque of the motor 30 is then transmitted to the driveshaft 22 with a gear change of the continuously variable transmission 50.

A vehicle includes an engine (10), a rotating electric machine (20), a high-voltage power line (PL, NL), a high-voltage battery B1, an inverter (30), a capacitor C1, an electronic control unit (100), a low-voltage battery (62), an alternator (61), and a low-voltage power line (60). The capacitor (C1) is connected to the high-voltage power line (PL, NL). The electronic control unit (100) is configured to control the engine (10) such that the engine (10) is operated and the alternator (61) supplies electric power to the low-voltage power line (60) in a case where the possibility of the occurrence of a collision of the vehicle is detected. The electronic control unit (100) is configured to perform control such that the capacitor (C1) discharges a residual electric charge in a case where the possibility of the occurrence of the collision of the vehicle is detected or in a case where the occurrence of the collision of the vehicle is detected.

The rotating shaft 45 of the motor MG2 is connected to and disconnected from the first coupled rotating shaft 36, the crankshaft 26 of the engine 22, and the drive shaft 39 is connected to and disconnected from the second coupled rotating shaft 37 and the third coupled rotating shaft 38. Thereby, the connection state when a power is output to the drive shaft 39 can be increased and the power to the drive shaft 39 can be output in a more efficient connection state in comparison with only connecting and disconnecting the rotating shaft 45 of the motor MG2 to and from the first coupled rotating shaft 36 and the crankshaft 26 of the engine 22.
