  • Publication number: 20130304361
    Abstract: Provided is an automatic stop and restart device for an engine that is capable of suppressing occurrence of an abnormal condition even if a transmission state is changed during an engine restart process after an engine restart condition is satisfied in an automatic engine stop process. A controller performs the automatic engine stop process and the engine restart process. If a determined state of a transmission is a drive range, a transmission state determination unit drives a pinion gear thrust unit at timing determined by a first pinion gear thrust timing determination unit. If the determined state of the transmission is a non-drive range, the transmission state determination unit drives the pinion gear thrust unit at timing determined by a second pinion gear thrust timing determination unit.

  • Publication number: 20130271082
    Abstract: In a power supply system provided with an assembled battery supervisory device which supervises an assembled battery composed of storage elements connected in series with one another, the system using the assembled battery is obtained which makes it possible to supply electric power to the assembled battery supervisory device, with a simple arrangement. The arrangement is such that electric power for the assembled battery supervisory device is obtained from a part of storage elements constituting the assembled battery. The cell balancer is driven based on the average consumption electric current of the assembled battery supervisory device so as to suppress a deviation in the amount of charge between those storage elements which supply electric power to the assembled battery supervisory device, and those storage elements which do not supply electric power to the assembled battery supervisory device, resulting from the average consumption electric current of the assembled battery supervisory device.

  • Publication number: 20120295757
    Abstract: A vehicle drive control system includes a motor coupled with the driving shaft of an internal combustion engine so that torque can be transmitted to the drive wheels when fuel supply to the engine is cut off. The vehicle travels in a creeping mode in this state while motoring of the engine is performed through driving force of the motor. When accelerator depression is detected, fuel injection into a cylinder waiting for the intake stroke of the engine is begun and the engine is started. The crank angle position at a time when fuel injection is started is utilized as a reference position. When the crankshaft of the engine rotates from the reference crank angle position to a predetermined crank angle position, driving by the motor is stopped and the vehicle is then driven by the engine.
