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.

Abstract: An oil pressure control device for a vehicle is configured such that, when switching from an oil pressure supply by means of a mechanical oil pump driven by a motor/generator to an oil pressure supply by means of an electric oil pump driven by a sub-motor, a supply ratio of oil supplied from the mechanical oil pump and a supply ratio of oil supplied from the electric oil pump, are adjusted based on an oil pressure difference between a first oil pressure and a second oil pressure, via first and second flapper valves. When the first oil pressure becomes less than or equal to a pump drive threshold, an increase in the second oil pressure is initiated, and the first oil pressure and the second oil pressure are made to match at a predetermined equilibrium oil pressure higher than a required line pressure.

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 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.
