Method for calculating instant of automatic clutch opening when stopping vehicle, comprises calculation based on clutch opening norm, engine speed, speed gradient, idling speed and supplement

摘要

The optimum instant for clutch opening is calculated by taking into account a clutch opening norm which is determined from fuzzy logic tables reflecting different types of drivers and situations, engine speed and speed gradient, idling speed and a tolerance supplement. The evolution of parameters such as gearbox entry speed (nGE) and engine torque (MsM) for emergency (A) and gentle braking (B) with long declutching are determined.
