  • Patent number: 9951686
    Abstract: A crankshaft bearing part (11) has a pair of main bearing metals (41), and lubricating oil is guided from an oil gallery to an inner circumferential oil groove (43) through an in-block oil passage (33) and a first oil hole (42). Some of the lubricating oil is supplied to a control shaft bearing part (17) via a second oil hole (44) and an in-cap oil passage (34). Lubricating oil is guided from a third oil hole (46) in a pair of control shaft bearing metals (45) to an inner circumferential oil groove (47). The oil groove (43) in the crankshaft bearing part (11) functions also as an oil passage for supplying lubricating oil to the control shaft bearing part (17), thereby achieving a simple configuration.

  • Patent number: 9951709
    Abstract: A hybrid electric vehicle comprises an internal combustion engine and an electric motor/generator connected via a first clutch. In response to a system stop request in a vehicle stop state, a rotation speed of the internal combustion engine is decreased to a predetermined rotation speed higher than a predetermined resonance frequency band by a negative torque applied to the internal combustion engine from the electric motor/generator via the first clutch. Then, the disengagement of the first clutch starts. The rotation speed of the engine falls below the predetermined resonance frequency band within a predetermined period from the start of the disengagement. As a consequence, the required period from a stopping operation of the internal combustion engine until actual operation stop thereof in a vehicle stationary state is reduced.

  • Patent number: 9951742
    Abstract: An ignition device for an internal combustion engine (1) includes a superpose voltage generation circuit (47) that, after the initiation of a discharge with the application of a discharge voltage by a secondary coil, applies a superpose voltage between electrodes of an ignition plug (29) in the same direction as the discharge voltage to continue a discharge current, and performs a superposed discharge in a superposed discharge activation range of high exhaust recirculation rate. Upon shift from the superposed discharge activation range of high exhaust recirculation rate to a superposed discharge deactivation range of low exhaust recirculation rate, the deactivation of the superposed discharge is delayed by a delay time ?T. Although the exhaust gas recirculation rate becomes temporarily increased with decrease in intake air after the closing of an exhaust gas recirculation control valve, the superposed discharge is continued for the delay time ?T so as to avoid misfiring.

  • Patent number: 9950697
    Abstract: A braking-driving force control system is provided in which erroneous vehicle speed detection may be avoided even when a frictional braking power is generated during rotation of an output shaft coupled to an electric driving motor as driving source. When only regenerative braking force is being generated as braking force while the vehicle is traveling, the braking force and the driving force are controlled based on an output shaft side vehicle speed calculated from the rotational state of an output shaft of a driving source, and when the frictional braking power is being generated while the vehicle is traveling, the braking force and the driving force will be controlled based on a wheel side vehicle speed representing the vehicle speed calculated from the rotational state of the vehicle wheel.

  • Patent number: 9929600
    Abstract: When a vehicle approaches a parking space, a ground controller excites a power transmission coil using an excitation pattern signal containing identification data, and a vehicle controller acquires the identification data from the excitation pattern signal received by at least one of subcoils. Then, a communication unit transmits the acquired identification data to the ground unit. The ground controller pairs the power transmission coil and the power reception coil with each other when the identification data contained in the excitation pattern signal and the identification data transmitted from the vehicle controller match each other. Also, the pairing is canceled if the identification data received by the subcoil provided on the front side and the identification data received by the subcoil provided on the rear side are different from each other.

  • Patent number: 9929628
    Abstract: A magnet insertion method into a rotor core is to insert an assembly into a magnet insertion hole provided in the rotor core of an electric motor, the assembly being formed by laminating a plurality of members, including at least a plurality of magnet pieces, in a line. According to this magnet insertion method, the assembly is formed by arranging a front member, having a surface surrounded by a chamfered ridge line, to cause the surface to be a front side end surface upon insertion, by laminating, on its rear side in an insertion direction, other members, without having the chamfered ridge line, in a line along the insertion direction to cause the other members to be hidden inside a projection of the front member when being projected from an insertion hole side, and by temporarily holding the front member and the other members.

  • Patent number: 9926988
    Abstract: A starting clutch control device for an automatic transmission has a starting clutch controller. The starting control device controls a transmission torque capacity of a starting clutch interposed in a transmission path in which rotation of the power source is transmitted to wheels while shifting is underway by the automatic transmission. The starting clutch controller controls the transmission torque capacity of the starting clutch such that a rotation trajectory of the power source develops as desired in a low rotation speed range in which the transmission torque capacity control of the starting clutch is necessary. The starting clutch controller causes the transmission torque capacity of the starting clutch to change, when a shift of the automatic transmission occurs during the transmission torque capacity control by the starting clutch controller, in a direction in which the change in the rotation trajectory will occur corresponding to the shift.
