  • Patent number: 10532733
    Abstract: A hybrid vehicle start control device is provided for a hybrid vehicle that ensures an EV reverse starting intended by a driver, even when an engagement command is issued to an engagement clutch that selects an ICE gear shift stage, when carrying out EV reverse starting. In this hybrid vehicle, a multistage gear transmission includes an EV shift actuator that selects an EV gear shift stage, and ICE shift actuators that select an ICE gear shift stage. A starting controller operates the EV electric actuator to select EV 1st of the multistage gear transmission at a time of starting, and that carries out an EV starting using the first motor/generator. At a time of an EV reverse starting, the starting controller carries out a control to the operating positions of the ICE shift actuators that prevent the selection of the ICE gear shift stage by the ICE shift actuators.

  • Patent number: 10312125
    Abstract: A protective tape that improves solder bonding properties and reduces wafer warping. The protective tape includes, in the following order, an adhesive agent layer, a first thermoplastic resin layer, a second thermoplastic resin layer, and a matrix film layer. The protective tape satisfies the conditions expressed by the following formulae (1) to (3): Ga>Gb??(1) Ta<Tb??(2) (Ga*Ta+Gb*Tb)/(Ta+Tb)?1.4E+06 Pa.??(3) Ga represents a shear storage modulus of the first thermoplastic resin layer at a pasting temperature at which the protective tape is pasted; Gb represents a shear storage modulus of the second thermoplastic resin layer at the pasting temperature at which the protective tape is pasted; Ta represents a thickness of the first thermoplastic resin layer; and Tb represents a thickness of the second thermoplastic resin layer.

  • Patent number: 10293811
    Abstract: A power generation control device is provided for a hybrid vehicle that prevents unintended engagement of a released engagement clutch during idle power generation. An internal combustion engine is operated during idle power generation so that the input-output differential rotation speed of engagement clutches for selectively connecting an electric motor and/or the internal combustion engine to the drive wheel becomes a value greater than or equal to a rotation difference threshold value at which the engagement clutches are not engaged.

  • Patent number: 10295052
    Abstract: A vehicle transmission control device is provided in a vehicle having a gear type transmission capable of selecting a plurality of gear shift patterns, and an electric oil pump for supplying lubricating oil to a gear-shifting mechanism. The vehicle transmission control device includes a transmission controller that selects a path having a small load on the lubricated parts from among the plurality of power transmission paths upon detecting a malfunction has occurred in the oil pump to prevent seizing of lubricated parts and damage to gear-shifting mechanism if a malfunction occurs in the oil pump.

  • Patent number: 10093166
    Abstract: A hybrid vehicle has a first motor/generator mechanically coupled to a drive wheel, a second motor/generator mechanically coupled to an internal combustion engine and a high-power battery that is electrically coupled to the motor/generators. The second motor/generator has a smaller electrical power generation capability than the first motor/generator. While starting the vehicle at a time of insufficient battery capacity required for the EV start, the power generation controller disconnects the first electric motor from the drive wheel, connects the first electric motor to the internal combustion engine, and carries out MG1 idle power generation in which the first electric motor generates power by receiving torque from the internal combustion engine. When the vehicle is stopped at a time of sufficient battery capacity, the power generation controller does not carry out the MG1 idle power generation and keeps the first electric motor mechanically coupled to the drive wheel.

  • Patent number: 10060514
    Abstract: A continuously variable chain-belt transmission (chain-belt CVT) housed in a transmission casing formed by a transmission case and a side cover, has a pair of conical disk pairs, each pair of which is rotatably supported by disk supporting portions provided in the transmission case and the side cover; a chain wound around the pair of conical disk pairs; a chain guide attached to the chain to restrain movement of the chain and having an annular guide portion that encloses an entire circumference, in cross section, of the chain; and a chain guide supporting portion supporting the chain guide between the transmission case and the side cover. The chain guide supporting portion has a fixing side chain guide supporting portion fixed to the transmission case and a connecting side chain guide supporting portion connecting to the fixing side chain guide supporting portion.
