Abstract: A vehicle is provided with a mechanical oil pump (O/P) that is driven by a motor/generator (MG), an electric oil pump (M/O/P) that is driven by a sub-motor (S/M) and a second clutch (CL2) that transmits the drive force of the motor/generator (MG) to left and right drive wheels (LT, RT). When an accelerator pedal is depressed while a brake pedal is still depressed, an integrated controller (10) drives the electric oil pump (M/O/P) before the brake pedal is released, and oil pressure supplied to the second clutch (CL2) is increased.

Abstract: A structure of a resin-made pipe joint includes a sleeve which is press-insertable from one axial side into one longitudinal end portion of a flexible tube to flare the one longitudinal end portion to hold the flared state, a joint body which is couplable to the sleeve, and a union nut which is fastenable to the joint body to hold a state where the sleeve press-inserted into the one longitudinal end portion is coupled to the joint body.

Abstract: A vehicle control device includes a motor, a clutch and a control unit. The motor is configured to apply torque to a power transmission path between an engine and a drive wheel. The clutch is disposed between the engine and the drive wheel. The control unit stops fuel injection of the engine when the engine is greater than or equal to a prescribed engine rotational speed during deceleration, and restarts the fuel injection after disengaging the clutch, and then stops the power running of the motor after resuming the fuel injection of the engine. The control unit drives the motor to carry out power running such that a deceleration of the vehicle becomes less than or equal to a prescribed value when fuel injection of the engine is stopped.

Abstract: A control method is performed to control first and second storage devices that are connected in parallel to an electric generator in which the second storage device has a lower internal resistance than that of the first storage device. In a case where a driver has requested automated driving during charging of the first storage device (e.g., a lead-acid battery) in a state in which a generator and the second storage device (e.g., a lithium-ion battery) are disconnected, the generator and the second storage device are electrically connected even when a charge ratio of the lead-acid battery is less than a prescribed percentage. In a case where the driver has not requested the automated driving, the generator and the second storage device are electrically connected after the charge ratio of the first storage device has reached the prescribed percentage.

Abstract: A repeater is used in an in-vehicle communication system for retransmitting communication frames between communication nodes. The repeater includes a storage unit, a retransmission unit, a determiner, and a generator. The storage unit stores a routing map that associates a frame ID that identifies a communication frame from a communication node and a destination of the communication frame. The retransmission unit retransmits the communication frame between the communication nodes based on the routing map stored in the storage unit. The determiner determines whether a preset condition for generating the routing map is satisfied. The generator generates the routing map based on information in the communication frame received from the communication node and stores the map in the storage unit when the determiner determines that the preset condition is satisfied.
