摘要：【課題】ハイブリッド車両において、電力消費量を燃料消費量に換算するための演算負荷を軽減し、かつバッテリの蓄電量を所定の範囲に収めることを目的とする。【解決手段】出発地点から目的地点に至る運行経路全体を対象区間として電力消費量を燃料消費量に換算するための電気価値係数Kおよび蓄電量Sを算出する。蓄電量が上限値Supと下限値Slowの間の使用範囲に収まれば、このとき算出された電気価値係数Kを採用する。蓄電量が使用範囲を逸脱したら(t1)、蓄電量が最大Smaxまたは最小となる時点(t2)までの区間を第1の区間とし、電気価値係数Kの算出を行い、これをこの区間の電気価値係数K1として採用する。次に、第1の区間の終点(t2)を始点とし、目的地点を終点とした区間において、前回と同様の処理を実行する。これを終点が目的地点に達するまで繰り返し、各区間ごとに電気価値係数K1,K2,K3・・・を設定する。【選択図】図8

摘要： PROBLEM TO BE SOLVED: To prevent generation of noises and to output required output to a drive shaft. SOLUTION: When the output shaft of an engine and a CVT are directly connected mechanically in order not to cause slipping, the target number of revolutions Ni* of an input shaft is set from a target torque Ti* requested by the CVT input shaft and a map for booming noises counter-measure (S106), and a limit torque Tlow is set from the then number of revolutions Ni of an input shaft and the map for the booming noise counter-measure (S106). When the target torque Ti* is larger than the limit torque Tlow, the limit torque is set to the engine target torque Te*, and at the same time, lacking toque is set to the torque command Tm of the motor 40 (S110-S116). When the target toque Ti* is lower than the limit torque Tlow, the target torque Ti* is set to the engine target torque Te* (S118) to execute an operation control of the engine, motor and CVT.

摘要： PROBLEM TO BE SOLVED: To prevent the damage of productivity as the confidential property of data is ensured when data on re-writable involatile memory is written. SOLUTION: The connection state of two change-over switches before and after decoding processing by a master ROM 22 in a microcomputer 20 is set to the (2) side during writing of first data and switched to the (1) side on and after second data writing. Thereby, decoding processing is not effected on data during first data writing and after decoding processing is made on data available on and after second data writing without fail, the data is respectively written at a flash ROM 23. Thereby, since, at first data writing, input data may be ordinary data, a work procedure is simple, a writing time is shortened, and productivity is improved. Since, on and after second data writing after delivery to a market, there is a need to use coding data, the confidential property of data is ensured and changing of data is reliably prevented.

摘要： PURPOSE:To accurately detect a yaw rate in a simple manner with no use of a steering angle sensor by computing the weighted means of the detected value and the zero value so as to renew the zero value when the difference between the detected value of the yaw rate and the zero value is in a specified range at the time of vehicle running. CONSTITUTION:Respective detection outputs from a vehicle speed sensor 10 and a yaw rate sensor 12 are inputted into an ECU 14 so that the quantity of steering for a vehicle is thereby operated. On the other hand, specified control signals based on the results of operations are outputted from the ECU 14 to a drive circuit 16 and an actuator 18 respectively so that rear wheels are thereby steered. In this case, the yaw rate is operated by the ECU 14 based on the zero value. And when the difference between the detected value of the yaw rate and the zero value is in a specified range, the weighted means of the detected value of the yaw rate and the zero value is computed in such a way that much more emphasis is given to the zero value, and the zero value is concurrently renewed based on the result of the aforesaid computation. This thereby allows the yaw rate to be accurately detected with no use of a steering angle sensor.
