  • Patent number: 10436131
    Abstract: A control device of an internal combustion engine, includes: a boost pressure detector to detect a boost pressure of air pressurized by a compressor of a supercharger including a turbine; and a processor configured to determine a rapid decrease in a target boost pressure; determine that an execution condition is satisfied in a case where the target boost pressure rapidly increases immediately after the rapid decrease is determined while the exhaust gas is refluxed; calculate a restriction opening control amount for an exhaust gas flow amount variable device to control a flow amount of the exhaust gas blown to the turbine so as to regulate a changing speed of an opening control amount to decrease an opening of the exhaust gas flow amount variable device when the execution condition is satisfied; and control the opening of the exhaust gas flow amount variable device according to the restriction opening control amount.

  • Patent number: 9950704
    Abstract: Provided is a charging control device that allows the actual state of charge of a secondary battery to converge quickly to an upper limit value given as a control center value when the actual state of charge is higher than the upper limit value so that charging may be performed in an efficient manner and fuel economy may be improved. The charging control device (10) includes a charge/discharge integration unit (23) for computing an integrated charge/discharge value (IW) of the secondary battery, a charge control unit (26) for controlling the charging of the secondary battery such that the recognized state of charge is maintained at a prescribed upper limit value (80%) lower than a fully charged state (100%) by switching a generation voltage of a generator.

  • Patent number: 9007034
    Abstract: An electric power generation control system for a vehicle, which enables generation of electric power by a generator as much as possible while preventing an electrical component from being overheated by power generation by the generator. The electric power generation control system selectively switches a mode of the generator between first and second modes in which an instruction voltage is higher and not higher than an allowable voltage of a wire harness, respectively. A counter value is counted up in the first mode and down in the second mode. When the counter value has reached a higher limit value, the first mode is inhibited and the power generation mode is set to the second mode. This increase the proportion of an execution time period of the first, and accordingly, when a possibility of overheating the wire harness becomes high, the instruction voltage is lowered.
