摘要:
A drive system includes an engine, a first differential mechanism that is connected to the engine and transmits rotation of the engine, a second differential mechanism that connects the first differential mechanism with drive wheels, a switching device that changes a speed ratio of the first differential mechanism, a first running condition, and a second running condition. The second differential mechanism has a first rotational element connected to an output element of the first differential mechanism, a second rotational element connected to a first rotating machine, and a third rotational element connected to a second rotating machine and the drive wheels. The first running condition is a running condition in which the vehicle runs using the second rotating machine as a power source, while differentially operating the first differential mechanism. The second running condition is a running condition in which the vehicle runs using the second rotating machine as a power source, without differentially operating the first differential mechanism. A region in which the vehicle runs in the second running condition in the case where the engine cannot start by itself (S10-N) is larger than that in the case where the engine can start by itself (S10-Y).
摘要:
Provided is a hybrid construction machine capable of appropriate control of engine speed based on a total load torque, reduction in energy loss due to the power for auxiliary devices and efficient operation of the engine and the generator motor, including a hydraulic pump, a generator motor, an engine, and a control device. The control device includes a total load torque determination section determining a total load torque, the sum of load torques for the hydraulic pump and the generator motor, and an engine speed control section controlling the engine speed based on the total load torque. The engine speed control section performs a regulation control of increasing the engine speed as the total load torque decreases under a high load torque condition and performs an isochronous control of maintaining the engine speed at a constant target speed N2 under a low load torque condition.

A control apparatus (100) for a hybrid vehicle controls the hybrid vehicle (1) provided with: an internal combustion engine (200); power elements including a first electric motor (MG1) and a second electric motor (MG2); and a drive shaft (500). The control apparatus (100) for the hybrid vehicle is provided with: a torque determining device (110) for determining respective divided torques to be outputted from the first electric motor and the second electric motor on the basis of total torque required for driving of the hybrid vehicle; a torque correcting device (140) for correcting the respective divided torques of the first electric motor and the second electric motor such that pulsation torque of the internal combustion engine on the drive shaft is canceled by the respective divided torques outputted from the first electric motor and the second electric motor and such that the respective divided torques of the first electric motor and the second electric motor are directed opposite to each other with respect to the drive shaft; and a controlling device (150) for controlling each of the first electric motor and the second electric motor so as to output respective one of the corrected divided torques.
摘要:
An ECU (26) makes a changeover between EV running and HV running in accordance with a running situation in each of a CD mode and a CS mode. A start power threshold of an engine (2) when the CD mode is selected is larger than the start power threshold when the CS mode is selected. Then, the ECU (26) changes the driving force characteristics of a vehicle depending on whether the CD mode or the CS mode is selected, such that the vehicle driving torque for the same vehicle speed and the same accelerator opening degree is larger when the CD mode is selected than when the CS mode is selected.
