Title:
CONTROL METHOD AND DEVICE FOR OUTPUT TORQUE OF VEHICLE DRIVE TRAIN
Document Type and Number:
Japanese Patent JPH10141103
Kind Code:
A
Abstract:

To assign output torque to an accelerating pedal position by determining the target value to the output torque of a drive train according to the minimum and/or maximum torque which is a function of an operation variable in addition to a driver's desire.

A rotating speed Nmot, an engine temperatrure Tmot, the state NA of an auxiliary machine, an air temperature, pressure PLuft, RLfut, information GANG on the speed change ratio, ignition angle efficiency dZW, and air-fule ratio setting efficiency are input (S100) to calculate (S102, 104) the maximum and minimum wheel torque Mradmax, Mradmin, and filtering is executed to determine the maximum and minium wheel torque Mramax (n), Mradmin (n) by multiplying the previous corresponding maximum and minimum wheel torque Mradmax (n-1), Mradmin (n-1) by a designated filter function or time function f(T). A value in the normalized accelerating pedal position βis input (S108), and the wheel torque target value Mradsoil is calculated (S110) by the accelerating pedal position β, the maximum and minimum wheel torque values to be output to a drive train control means.
