摘要:
The invention includes a target-engine-speed acquisition element that acquires a target engine speed necessary to reduce engine speed, thereby stopping the engine at a target stop position; a crank-angle acquisition element that acquires a crank angle indicative of the position of a crankshaft; and a target-engine-speed correction element that corrects the target engine speed according to the acquired crank angle. Because the target engine speed is corrected according to the crank angle, the engine can be stopped at the target stop position even if the friction in the engine, the electric motor, etc. varies, the temperature or viscosity of the lubricating and cooling oils varies, or the vehicle is accelerated or decelerated during the reduction of the engine speed.

An apparatus and a method to stably run an electrically operated vehicle is disclosed. The invention has an electric generator target torque calculation processor, a first determination processor for calculating an inertia correction determining value, a second determination processor for calculating an integral term correction determining value, a determining mode switching condition judgment processor, and a drive motor target torque calculation processor. When a determining mode switching condition exists, the drive motor target torque calculation processor switches between a first determining mode for calculating drive motor target torque, and a second determining mode for calculating the drive motor target torque. When the determining mode switching condition exists, the first determining mode and the second determining mode are switched so that the drive motor target torque is calculated on the basis of the integral term correction determining value.

An apparatus and a method to stably run an electrically operated vehicle is disclosed. The invention has an electric generator target torque calculation processor for calculating electric generator target torque showing a target value of electric generator torque by feedback control for performing at least integral control; a determination processor for calculating an integral term correction determining value on the basis of an integral term component of the electric generator target torque in the integral control; and a drive motor target torque calculation processor for calculating drive motor target torque showing a target value of drive motor torque on the basis of the integral term correction determining value. Since the drive motor target torque is calculated on the basis of the integral term correction determining value, no error is generated in the drive motor target torque and the electrically operated vehicle is stably run.

A hybrid vehicle includes an engine and a first electric motor mechanically connected to the engine and to a drive wheel. The engine is startable by the first electric motor. The hybrid vehicle further includes: start condition satisfaction determination processing system and method for determining whether a variable that varies corresponding to the rotation of the drive wheel is equal to or greater than a threshold set within a range that does not exceed an upper limit value prescribed by a maximum torque of the first electric motor and a torque of the first electric motor needed to start the engine; and engine start instruction output processing system and method for outputting an engine start instruction if the variable is equal to or greater than the threshold. If the variable is greater than or equal to the threshold, the engine start instruction is outputted, and the engine is immediately started.

The invention has an engine maximum torque calculating processor for calculating plural engine maximum torques showing a maximum value of engine torque, and an engine limit torque calculating processor for calculating a minimum value of the respective engine maximum torques as engine limit torque. Because the minimum value of the engine maximum torques is calculated as the engine limit torque, it is possible to reliably prevent the engine from entering an excessive rotating state. Further, because the engine limit torque is calculated on the basis of the minimum value of the engine maximum torques, the engine limit torque can be reliably calculated even when there is an individual difference in the engine, an electric generator, etc. and there are calculation errors further, for example, electric generator target torque and the electric generator maximum torque.
