Method for determining energy equivalence factor for hybrid power train for car, involves controlling energy equivalence factor according to instantaneous state of battery power and target energy and depending on driving conditions of car

摘要

The method involves controlling an energy equivalence factor (S) in a discrete manner according to an instantaneous state of battery power (soe-k) and a target energy (soe-cible) and depending on driving conditions of a car, where the target energy is a function of predictions of the driving conditions of the car. An integrated term is presented on the estimate of the state of energy of the battery, where the integrated term is a function of a difference between the target energy and the instantaneous state of energy of the battery. An independent claim is also included for a device for determining an energy equivalence factor.
