ADAPTIVE CONTROL OF MOTOR VEHICLE POWERTRAIN

摘要

A method and system is disclosed for blending between different torque maps of a vehicle so that step changes of torque output are avoided as accelerator pedal position is changed. The invention provides different blending rates so as to reduce the blending time if driver demand is in the direction of torque change.

1. A method of blending between different characteristics of accelerator position and output torque in a vehicle, the method comprising:
detecting a first operating mode of a vehicle and applying a source characteristic; detecting a change of operating mode of the vehicle and selecting a target characteristic; blending the characteristic applied from said source characteristic to the target characteristic at a base blending rate, said blending rate being increased if during blending the position of the accelerator pedal is moved in the direction of torque change due to blending.
