Embodiment Construction

[0016] In this arrangement, the first comparator C1 receives as input the energy state of the battery at time K soe k and target energy state value soe 目标 . Poor (soe 目标 -soe k ) times the correction gain K p . The result of the second comparator C2 [K p (soe 目标 -soe k )] is summed with a correction term of integral type, which ensures a correction of the equivalent factor based on the operating conditions encountered. Saturator S saturates this sum, which ensures that the equivalent factor will remain within control limits. Minimum Saturation (sat min -1 / η) and maximum saturation (sat max The -1 / η) limit ensures that forced charge and discharge modes are controlled.

[0017] Saturation max max It is the maximum equivalent value to ensure that the motor propulsion pack is controlled so that the energy of the battery is charged to the maximum extent. saturation sat min is the equivalent factor to ensure that the motor propulsion pack is controlled to the minimum e...

Abstract

Equivalent energy factor(s) for determining the weighting applied between the delivery of thermogenic energy and the delivery of electrogenic energy so as to minimize at an operating point Method of total energy consumption of a hybrid motor propulsion of a motor vehicle powered by at least one electric motor, characterized in that this factor is based on the instantaneous state of energy (soek) of the battery and on the target energy (soe target) and on the basis of the vehicle The health of the system is controlled in a discrete manner.

Description

technical field [0001] The invention relates to the management of energy flux distribution in a hybrid motor propulsion of a motor vehicle. [0002] More precisely, the invention relates to the determination of an energy equivalence factor representing the weight to be applied between the delivery of thermogenic energy and the delivery of electrogenic energy in order to minimize at an operating point The total energy consumption of a hybrid motor propulsion of a motor vehicle of the type powered by at least one electric motor. Background technique [0003] The motor propulsion of a motor vehicle with hybrid propulsion or traction includes a heat engine and one or more electric machines powered by at least one battery mounted on board the vehicle. [0004] Systems for controlling hybrid motor propulsion have been designed to manage the operation and synchronization of the different motors based on operating conditions in order to limit fuel consumption and minimize the emiss...
