A hybrid vehicle drive control system selectively switches from an electric drive (EV) mode in which a first clutch is released and a second clutch is engaged, and a hybrid drive (HEV) mode in which both clutches are engaged. A slip control of the second clutch is executed when the first clutch is being connected to start the engine during switching from EV mode to HEV mode by controlling a torque transfer capacity of the second clutch to a required drive force, and by simultaneously increasing a motor/generator torque by an amount corresponding to a torque required to start the engine while maintaining a slipping state of the second clutch until connection of the first clutch is completed. Thus, a loss of torque is not felt by the driver and the shock is small when the engine is started during switching from EV mode to HEV mode.

A hybrid vehicle drive control system has a first clutch interposed between an engine and a motor/generator, a transmission including several gear position clutches arranged between the motor/generator and a drive wheel, and a controller. The controller selectively starts the engine using torque from the first clutch during a mode drive change from an electric drive mode to a hybrid drive mode. When an engine start command occurs during the drive mode change, the controller selects the engaged gear position clutch that has the maximum torque transfer capacity from the engaged clutches constituting a vehicle running gear occurring during an engine starting process as a second clutch to be controlled. Then the controller executes a slip control of the second clutch when the first clutch is being connected to start the engine during the mode change from the electric drive mode to the hybrid drive mode.

The modulator/demodulator is adapted to communicate data on each line using the subset of available tones. A method for allocating the resources of a communications system includes determining an amount of available processing resources for a processing unit. The processing unit is adapted to support a plurality of connections over a plurality of lines. Each connection has an associated tone set for communicating data. A first connection is established over a first line. A first portion of the available processing resources is allocated to the first connection. A first tone range is determined based on the first portion. The first tone range is a subset of the tone set associated with the first line.

A hybrid vehicle control apparatus is provided with an engine, an electric motor, a holding element, an automatic transmission, a range position detecting device and a controller. The holding element is arranged between the engine and the electric motor to selectively connect and disconnect the engine and the electric motor to and from each other. The automatic transmission is arranged between the electric motor and a drive wheel. The range position detecting device detects a range position of the automatic transmission selected by a driver. The controller executes a control operation serving to stop the engine while also executing a slip control serving to lower a torque transfer capacity of the holding element upon a determination that a request to stop the engine has occurred while the engine is operating, the holding element is engaged, and the automatic transmission is detected in a non-driving range.

An IRD 103 supplies broadcasting data on a bus in a desired time period. When the IRD 103 performs a reservation of the bus usage, the IRD 103 requests current bus usage information and information of the bus reservation from all devices connected by the bus, such as a DVD 104, a D-VTR 101, a D-VTR 102, a CAM 105, a TV 100, and a isochronous manager 107 of the D-VTR 101. The isochronous manager 107 and each device answer by sending the bus usage information and reservation information to the IRD 103. The IRD 103 judges a possibility of the reservation from the answer information. If the reservation is possible, it performs the reservation operation. If the reservation is impossible, then the reason is displayed on a TV 100. Therefore, it is possible to prevent a usage of a device that excesses the bus transferring capacity.

Available transfer capacity is apportioned efficiently by stations informing each other of their capacity needs by sending messages when necessary. The sent messages can contain information on priority and capacity requirement. Stations which receive the sent capacity requests release unrequired transfer capacity or transfer capacity which is not urgently required, so that the capacity can by used by a station in need. The corresponding information can also be transferred by other stations, e.g. by several hops.
