摘要： PROBLEM TO BE SOLVED: To establish both the protection of a transmission and the guarantee of the driveability of a vehicle in the failure of a rear wheel speed sensor. SOLUTION: A drive force control device for vehicle is constituted so that a low friction coefficient road surface is determined by using at least a rear wheel speed detected by a rear wheel speed sensor, and when the low friction coefficient road surface is determined, the restriction of fail cut or shift change is performed to protect a transmission. When the condition of (a) is established, or at least either the condition of (b) or the condition of (c) is established from among the following conditions: (a) a rear wheel sensor is abnormal (step S114); (b) a prescribed time has passed after a shift range is operated from a reverse range to a drive range (step S112); and (c) a shift level is turned to be 3 speeds or more (step S113), the determination of the low friction coefficient road surface using the rear wheel speed which is likely to be abnormal is inhibited, and the rear wheel speed is substituted with the axle speed calculated from the output axial rotational speed of the transmission.

摘要： PCT No. PCT/EP95/00595 Sec. 371 Date Aug. 16, 1996 Sec. 102(e) Date Aug. 16, 1996 PCT Filed Feb. 18, 1995 PCT Pub. No. WO95/23303 PCT Pub. Date Aug. 31, 1995A process is proposed for controlling an automatic transmission wherein a transition occurs from a first, lower reduction step to a second, higher reduction step when a first clutch disengages and a second clutch engages and a synchronizer speed is calculated by multiplying the transmission output speed by the reduction ratio of the second reduction step. A speed value, at which the pressure increase of the second clutch begins, is assigned to the synchronizer speed from a characteristic curve. The characteristic curve is adapted if the transmission input speed exceeds the synchronizer speed or if the gradient of the transmission input speed exceeds a limit value.

摘要： A vehicle automatic transmission control controls fluid pressure changes applied to a frictional engagement element which is being changed from an engaged state to a disengaged state at a stage before input shaft rotational speed starts to increase from the beginning of a down-shift control. The control instruction value is set to gradually decrease the applied fluid pressure and to increase the ratio of such decrease with elapsed time. Specifically, a solenoid is used to control the fluid pressure applied to a clutch. The duty-cycle instruction for the solenoid is determined based on a quadratic function expressed as: duty cycle value=initial value-at2.

摘要：正常時油圧設定手段72は、入力トルクとトルク分担とに基づき、各変速段で係合される2つの摩擦係合要素における伝達トルクを算出し、それらの油圧サーボにそれぞれ供給する係合圧を設定する。この設定された係合圧は、それら2つの摩擦係合要素に滑りが生じず、かつ解放中の別の摩擦係合要素の油圧サーボにライン圧が供給されて3つの摩擦係合要素が同時係合されたとしても、トルク分担が変更されることで、3つのうちの1つの摩擦係合要素が車輌の慣性力によって滑るように設定されている。3つの摩擦係合要素が同時係合しても、そのうち1つの摩擦係合要素が滑るので、カットオフバルブを用いることなく、走行状態を確保することができ、コンパクト化、軽量化、コストダウンが可能となる。
