摘要： A torque control device is provided to prevent slipping of a belt of a belt type continuously variable transmission. The torque control device calculates a positive input torque inputted from an engine to a primary pulley, and calculates a negative input torque inputted from a drive wheel to the primary pulley based on the positive input torque and a speed ratio of a continuously variable section. The torque control device then restricts an output torque from the engine so that the total torque can be lower than or equal to the torque capacity of the belt when the vehicle is in a running state in which the negative input torque is likely to occur and the total torque which is the sum of the positive input torque and the negative input torque exceeds the torque capacity.

摘要： A CVT has a torque convener (T/C) speed ratio calculation section that determines the speed ratio from the engine speed and the primary pulley speed. The calculation section then calculates the torque ratio from the speed ratio. An input torque estimation section then estimates the input torque input into CVT from the torque ratio and the determined engine output torque. The T/C speed ratio calculation section, having a correction amount calculation section, reduces the speed ratio when the accelerator pedal is depressed to less than Np/Ne. Because the disparity with real value of the speed ratio occurring in the dead time of the respective revolution sensors can be decreased and the input torque properly estimated, slippage between the V belt and the variable pulley is prevented.
摘要翻译： CVT具有根据发动机转速和主滑轮速度决定变速比的转矩调节器（T / C）变速比计算部。然后，运算部根据转速比计算转矩比。然后，输入转矩估计部从扭矩比和确定的发动机输出转矩估计输入到CVT的输入转矩。具有校正量计算部的T / C变速比计算部将加速踏板被压下的速比降低到小于Np / Ne。由于可以减少在各旋转传感器的死区时间中发生的速比的实际值的差异，并且适当地估计输入转矩，可以防止V带与可变滑轮之间的滑动。

摘要： A clutch engagement control device controls the engagement of a forward clutch (32) and reverse clutch (33) in an automatic transmission connected to an engine (70) in a vehicle. An inhibitor switch (56) outputs a range signal in accordance with a position range of a select lever (51). A manual valve (57) supplies oil pressure selectively to one of the forward clutch (32) and the reverse clutch (33) by changing position in accordance with the position range of the select lever (51). A controller (60) of the clutch engagement control device determines whether an unmatching range condition occurs in which the range of the select lever (51) indicated by the range signal and the range of the manual valve (57) do not match, when the range of the select lever (51) indicated by the range signal is a drive range or reverse range; and suppress an increase in engine rotation speed prior to engagement of the forward clutch or reverse clutch when the unmatching range condition occurs.

摘要： There is provided an engine torque control apparatus that is comprised of a torque-down amount calculating section to which the throttle valve opening and the engine speed are inputted and which calculates the torque-down amount based on the inputted values, an inertia correction amount calculating section that calculates the correction amount for inertia of each component part (inertia discharged torque), a friction correction amount calculating section that calculates the correction amount for friction generated by a belt CVT (friction discharged torque), a torque-down amount correcting section that corrects the torque-down amount based on the calculated correction amounts, and an engine torque control section that controls engine torque. Since the engine torque is controlled with inertia and friction discharged torque of each component part being taken into account, the upper limit of the torque inputted to an automatic transmission can be accurately controlled to the value of the allowable input torque of the automatic transmission.
