Dans ce procédé de répartition d'un couple global (Cglobal) de consigne entre les trains de roues d'un véhicule, une première branche (20) comporte une étape consistant à soustraire (22) au couple global (Cglobal) de consigne un couple optimal (Car_opti), de façon à obtenir un premier couple de consigne (Cav) à appliquer à un premier train et une deuxième branche (30) comporte des étapes consistant à soustraire (31) au couple global (Cgiobal) de consigne un couple estimé (Cav_estim) associé au premier train, de façon à obtenir un deuxième couple de consigne (Car) à appliquer à un deuxième train, puis à limiter (32) le deuxième couple de consigne (Car) entre un couple minimum et un couple maximum prédéfinis. La première branche (20) comporte en outre une étape consistant à limiter (21) le couple optimal (Car_opti) entre le couple minimum et le couple maximum avant de calculer le premier couple (Cav).
摘要:
A method of controlling a plug-in hybrid electric vehicle including an electric propulsion system, an engine, and a catalytic converter associated with the engine, the method comprising: monitoring a state of charge of a battery of the vehicle when in a charge depletion mode; determining a rate of depletion of the state of charge; estimating from the rate of depletion a duration of a depletion period representing the time remaining until a minimum state of charge of the battery will be reached; determining a duration of a warming period of the catalytic converter; comparing the duration of the depletion period and the duration of the warming period; and activating the engine if the duration of the depletion period is less than or equal to the duration of the warming period.
摘要:
A hybrid vehicle includes an engine (10), a first motor generator (MG1), a second motor generator (MG2), a transmission unit (power transmission unit) (40), a differential unit (50), a clutch (CS) and a mechanical oil pump (501). The hybrid vehicle is able to switch between series-parallel mode in which power of the engine is transmitted via the transmission unit and the differential unit and series mode in which power of the engine is transmitted via the clutch. The differential unit (50) is a planetary gear mechanism including a sun gear (S2) connected to the first motor generator (MG1), a ring gear (R2) connected to the second motor generator (MG2), and a carrier (CA2) connected to a ring gear (R1) that is an output element of the transmission unit (40). The mechanical oil pump (501) is driven by power that is transmitted from the carrier (CA2) of the differential unit.
