An electrically operated vehicle drive controller used with an electrically operated machine, an output shaft differentially rotatably connected to an engine and the electrically operated machine, and a differential rotating unit having a first differential rotating element connected to the electrically operated machine, a second differential rotating element connected to the output shaft, a third differential rotating element connected to the engine, a rotating body rotatably arranged on a support shaft in one of the first to third differential rotating elements and meshed with the other two differential rotating elements, and an engine control processor that controls the operation of the engine on the basis of the rotating speed of the rotating body. Because the operation of the engine is controlled on the basis of the rotating speed of the rotating body, it is possible to prevent the rotating speed of the rotating body from becoming higher than an upper limit value.

Electrically operated vehicle drive controller, electrically operated vehicle drive control method, and electrically operated vehicle with a vehicle drive controller

A control apparatus and method for a hybrid vehicle that judges whether the vehicle is running on a congested road based on an output from a sensor, causes a take-off from a first state where a gear ratio of an automatic transmission is large at a time of taking-off when running on a congested road, causes the take-off from a second state where the gear ratio of the automatic transmission is small at the time of taking-off when not running on the congested road and replenishes, by driving a motor/generator, a part of an under torque of the driving source created by taking-off from a state where the gear ratio of the automatic transmission is large, when a temporary high acceleration take-off request is made while a judgment of congested road running is maintained.

Control apparatus of hybrid vehicle

A control system for a hybrid vehicle accurately determines the start (i.e. ignition) of an internal combustion engine and suppresses the peak PK in the actual rotational speed. The hybrid vehicle is provided with a motor control unit for, at the time of starting the internal combustion engine, driving the motor to rotate at a target motor rotational speed and with a vehicle control unit for, when the rotational speed of the internal combustion engine has reached a predetermined value, outputting an ignition command to start the internal combustion engine. After the ignition command is output to the internal combustion engine, the vehicle control unit calculates the difference between the target rotational speed of the motor and the actual rotational speed of the motor, and if the difference exceeds a predetermined value, determines that the ignition of the internal combustion engine has been effected. In this manner, the start of the internal combustion engine can be accurately detected. Once start of the internal combustion engine has been confirmed, the motor is controlled accordingly. As a result, the peak PK is suppressed.
