Title:
連続調整可能トランスミッション(CVT)付き車両でのトランスミッション被駆動トルクまたはトランスミッション出力の調整装置
Document Type and Number:
Japanese Patent JP3612083
Kind Code:
B2
Abstract:
An arrangement is proposed for regulating the transmission output torque or the transmission output power in vehicles with an internal combustion engine (10) and a continuously variable transmission (12) to a value predetermined by the driver, which arrangement is provided with means for the setting of a reference value for the transmission output torque or the output power of the transmission (12) as a function of the position of the accelerator pedal (14) and of the vehicle speed, and with means (18-20) for calculating a reference value for the engine torque of the internal combustion engine from the value for the transmission output torque or the transmission output power, predetermined by the driver, and from the actual value of the transmission ratio. The means (16) for setting a reference value for the transmission ratio contain a set of characteristic curves or a calculation sequence, in which values for this transmission ratio as a function of the transmission output speed and the position of the accelerator pedal (14) or of the reference value for the transmission output torque according to a predeterminable operating strategy for the internal combustion engine are stored or calculated, the reference value of the engine torque being calculated in such a way that the actual value of the transmission output torque or the transmission output power being set in connection with the actual value of the transmission ratio matches the reference value predetermined by the driver. In this way the optimum transmission ratio with reference to the fuel consumption, for example, is automatically set for any speed and any desired tractive force, provided that an operating strategy designed to optimise consumption has been selected.
