Title:
1つの内燃機関と2つの電気機器とによって駆動される自動車を運転する方法
Document Type and Number:
Japanese Patent JP4382349
Kind Code:
B2
Abstract:
Two methods for operating a motor vehicle driven by an internal combustion engine (VM) and by two electrical machines (E1, E2) are proposed. The motor vehicle has a transmission (G) with two power paths (LP1, LP2) controllable independently of one another. Each power path (LP1, LP2) is coupled via a respective epicyclic gear (P1, P2) to one of the electrical machines (LP1, LP2) and to the input shaft (KW) of the transmission (G) and can be coupled via shiftable gears (1, 2, 3, 4, 5, 6, R) to the output shaft (AW) of the transmission (G). The object is to make it possible to operate the motor vehicle more efficiently. To reduce circulating mechanical power flow between the two power paths (LP1, LP2), particularly in the boost mode or upon recuperation of braking energy, the gear combination (1, 2, 3, 4, 5, 6, R) is varied, or the engine rpm is lowered, or only one electrical machine (E1, E2) is used as a generator. More-comfortable operation is additionally achieved in that upon electrical starting, the engine (VM) is started simultaneously.
