  • Publication number: 20240093769
    Abstract: A vehicle control apparatus is to be applied to a vehicle including a torque converter and an engine. The vehicle control apparatus includes a turbine hub, a lock-up piston, a damper mechanism, and a control system. The damper mechanism permits relative rotation between a hub of the turbine hub and a cylindrical part of the lock-up piston. The control system controls the engine. The control system calculates, with the lock-up piston engaged with a crankshaft of the engine, a PV value that is a product of a sliding surface pressure and a sliding speed between the hub and the cylindrical part. When the PV value is greater than a threshold, the control system changes an engine torque more gradually than when the PV value is equal to or less than the threshold. The engine torque is an output torque of the crankshaft.

  • Publication number: 20220348225
    Abstract: An autonomous driving apparatus, which is used in a subject vehicle capable of performing an autonomous driving, is configured to: determine a deviation value of each of one or more candidate routes, which indicates a possibility of the subject vehicle deviating from a traveling rule when the subject vehicle travels the corresponding candidate route, based on a comparison result between an inter-vehicle distance and a minimum control permission distance; select one candidate route having the deviation value within a control permission range as a target route; output an instruction for controlling the subject vehicle to travel along the selected target route; execute a traveling control of the subject vehicle according to the instruction; and update a determination rule of the deviation value in response to a change in a sensor that detects a behavior of at least one of the subject vehicle or the peripheral vehicle.

  • Publication number: 20200278697
    Abstract: A thruster controller is used in a flying device that has at least two thrusters and a main controller that outputs an instruction value to the thruster for controlling a thrust of the thruster. The thruster controller includes an instruction value obtainer and an instruction value generator. The instruction value obtainer obtains an instruction value that is output from the main controller to the thruster based on an assumption that a propeller pitch is fixed. The instruction value generator outputs, to a pitch changing mechanism of the thruster, a propeller pitch instruction value generated from the obtained instruction value for setting the propeller pitch, and outputs, to a motor, a corrected rotation number instruction value for setting a rotation number of the motor by correcting the instruction value based on the propeller pitch instruction value.

  • Publication number: 20160118904
    Abstract: In a power conversion apparatus, an AC/DC conversion circuit part converts AC power supplied from an AC input and output part into DC power. A DC/DC conversion circuit part including a transformer converts the DC power supplied from the AC/DC conversion circuit part into AC power, converts converted AC power into DC power after voltage conversion by the transformer and outputs converted DC power to a DC input and output part. A smoothing capacitor is provided in a connection part between the AC/DC conversion circuit part and the DC/DC conversion circuit part to smooth a voltage at the connection part. A connection switchover part changes a maximum value of the AC voltage at the AC input and output part by switching over a connection state between the AC input and output part and an AC device.

  • Publication number: 20120314461
    Abstract: A power converter that is able to lower the level of switching noise in a wide frequency range is disclosed. In detail, the power converter converts an input power by controlling a switching element on the basis of a switching frequency discrete pattern. The switching frequency discrete pattern is composed in such a manner that a main discrete pattern and a sub discrete pattern are synthesized. The main discrete pattern is regulated by a plurality of transitionally discrete frequencies. Also the sub discrete pattern is regulated by a plurality of transitionally discrete frequencies in which a gap of the magnitude among consequent frequencies is smaller than that of the main discrete pattern.
