Abstract: PROBLEM TO BE SOLVED: To avoid the charge/discharge of storage means caused by excessive power concerning a motive force output device which is provided with the charging/discharging enabled storage means, performs the torque transformation of motive force outputted from a motor to desired motive force and outputs it to a driving shaft. SOLUTION: The motive force outputted from an engine 50 is torque- transformed to the desired motive force and outputted to a driving shaft 22 by a clutch motor 30 and an assist motor 40 connected to a crank shaft 56 and the driving shaft 22. At such a time, the excess/lack of power to be recovered or consumed by both the motors 30 and 40 is compensated by charging/discharging a battery 94. When the excess/lack of power exceeds an allowable range for charging/discharging the battery 94, the torquecommand value of assist motor 40 is reset so as to settle it within the allowable range. As a result, the power for charging/discharging the battery 94 can be settled within the allowable range without affecting the operation of engine 50.

Abstract: PURPOSE:To send each frame continuously without giving a token to a succeeding communication node when plural frames to be sent by a communication node are in existence at the acquisition of a token by one communication node in the token bus system communication system. CONSTITUTION:An address check controller circuit 90 acquires a token based on a transmission frame from a token bus Tb and outputs an address required to acquire a token of a communication node N1 when number of transmission frames from a transmission buffer circuit 20 is 2. Then a transmission format conversion circuit 40 converts data of one transmission frame into a transmission format and sends the result. When the transmission frame number of the transmission buffer circuit 20 is 1 and an output address of the address check controller circuit 90 reaches a setting address of the communication node N1, the transmission format conversion circuit 40 converts data of other transmission frame of the transmission buffer circuit 20 into a transmission format and sends the result.

Abstract: PURPOSE:To control an electric vehicle with excellent efficiency by executing total control of each component while lowering output torque from a vehicle drive motor when the pressure of a battery electrolyte drops. CONSTITUTION:An output from a main battery 10 is fed to motor/speed reducer 14 through an inverter main circuit 12. A short register 16, a charger 18, a DC/DC converter 20 and an auxiliary battery 22 are connected to the main battery 10. A control circuit 26 total-controls each component in response to an output from a memory section 31 storing battery maintenance information, vehicle drive information, charging information and fail information. When the pressure of an electrolyte in the battery 10 drops, output torque from a current motor is lowered, thus inhibiting the power consumption of the battery.
