PROCEDE DE PILOTAGE D'UN CHANGEMENT DE RAPPORT DE VITESSES D'UN VEHICULE HYBRIDE.

摘要

The method involves calculating derivative of speed of a vehicle with respect to time, and comparing a sign of the speed with longitudinal acceleration of the vehicle for establishing a running direction of the vehicle. An electric machine (16) is controlled according to the direction such that the machine applies the torque in a direction ensuring optimal speed synchronization irrespective of a slope direction and forward/reverse directions of the vehicle on a slope, where the machine is connected to a primary shaft (10) of a gear box (12).
