摘要:
A split serial-parallel hybrid dual-power drive system, comprised of two or more than two separation drive systems (1001,1002) allowing independent operation to respectively drive the load (120), or all loads driven individually are incorporated in a common frame to drive land, surface, underwater transportation means or aircraft, industrial machines and equipment or any other load drive by rotational kinetic energy. The first drive system can be disconnected (112) from the load and drive a generator (101) and the second electric machine (103) of the second drive system (1002) is driven by the generated electricity.

A control apparatus and method of controlling a hybrid vehicle are taught herein. The vehicle selectively switches between an EV mode wherein the vehicle travels by only a driving force produced by the motor/generator when an accelerator opening is less than or equal to an engine-stop line or a HEV mode wherein the vehicle travels by at least a driving force produced by the engine the accelerator opening exceeds the engine-stop line. A transition from the HEV mode to the EV mode is executed when the accelerator opening becomes less than or equal to the engine-stop line during the HEV mode and a given delay time has expired. The delay time is set to a shorter time as an accelerator return speed decreases.

A hybrid vehicle control apparatus (100) is provided with: a first replacement controlling device which replaces regenerative braking torque of the rotating electrical machine by engagement torque of the clutch if probability of starting an internal combustion engine is high on demand of changing a connection state between a rotating electrical machine and a transmission mechanism in regenerative braking by the regenerative braking torque of the rotating electrical machine; and a second replacement controlling device which replaces the regenerative braking torque by friction braking torque if the start probability is low on the change demand.

Vehicular drive system which is small-sized and/or improved in its fuel economy. A power distributing mechanism 16, which is provided with a differential-state switching device in the form of a switching clutch C0 and a switching brake B0, is switchable by the switching device between a differential state (continuously-variable shifting state) in which the mechanism is operable as an electrically controlled continuously variable transmission, and a fixed-speed-ratio shifting state in which the mechanism is operable as a transmission having a fixed speed ratio or ratios. The power distributing mechanism 16 is placed in the fixed-speed-ratio shifting state during a high-speed running of the vehicle or a high-speed operation of engine 8, so that the output of the engine 8 is transmitted to drive wheels 38 primarily through a mechanical power transmitting path, whereby fuel economy of the vehicle is improved owing to reduction of a loss of conversion of a mechanical energy into an electric energy. The mechanism 16 is also placed in the fixed-speed-ratio shifting state during a high-output operation of the engine 8, so that the required electric reaction of first electric motor M1 can be reduced, whereby the required size of the first electric motor M1, and the required size of the drive system 10 including the electric motor M1 can be reduced.
