Embodiment Construction

[0060] Next, a first embodiment of the present invention will be described with reference to FIGS. 1 to 11. FIG. FIG. 3 shows the configuration of an electric four-wheel-drive vehicle of a hybrid vehicle (hereinafter referred to as "HEV") according to this embodiment. Reference numeral 1 in the figure is a prime mover constituting one driving source of the HEV, and shows an engine as an internal combustion engine that burns and explodes fuel in a cylinder. Reference numeral 5 denotes a prime mover constituting another drive source of the HEV, and shows an electric motor as a rotating electrical machine that converts electrical energy into mechanical energy.

[0061] The engine 1 is an engine with a displacement of 1400 cc and a maximum torque of about 130 N·m / rpm, and its output shaft is mechanically connected to the drive shaft of the front wheels 14 through an automatic transmission (T / M) 12 . The output of the engine 1 is transmitted to the drive shaft of the front wheels ...

Abstract

In a hybrid car, or an electric motor-driven four-wheel-drive vehicle, in which an electric motor is driven directly by an output from a generator, vehicle running performance is enhanced. The output from the generator is controlled so as to maintain a generator torque in a range, in which the vehicle does not stall. Specifically, a driving apparatus for the hybrid car includes a second generator 2 driven by an engine 1 for driving one pair of either front or rear wheels 14, 15 , an electric motor 5 driven through directly receiving the output from the second generator 2 and driving the other pair of either the front or rear wheels 14, 15 , and a four-wheel-drive control unit 6 controlling driving of the second generator 2 and the electric motor 5 . When the engine 1 is in an overloaded condition, the four-wheel-drive control unit 6 limits the output of the second generator 2.

Description

technical field [0001] The present invention relates to a hybrid motor vehicle using an internal combustion engine and an electric motor as driving sources and a driving device thereof. In addition, the present invention relates to a hybrid four-wheel drive vehicle having a transmission with a clutch and a control device thereof. Background technique [0002] As a hybrid vehicle having an internal combustion engine and an electric motor as drive sources, for example, vehicles disclosed in Patent Documents 1 and 2 are known. Patent Document 1 discloses a four-wheel drive device in which a motor that rotationally drives the front wheels rotationally drives a generator, and a motor that rotationally drives the rear wheels is rotationally driven by the power generated by the generator (for example, refer to Patent Document 1 page 3 and Figure 1). Patent Document 2 discloses that an engine drives a generator that drives the front wheels, and a motor / generator that drives the re...
