Abstract:
PROBLEM TO BE SOLVED: To improve the mileage of a hybrid electric vehicle. SOLUTION: A drive control device defines a schedule of the recommended accelerator operation for each of a plurality of sections in a route from an origin to a destination, in order to attain enhanced fuel efficient running of the vehicle. The drive control device displays a recommended accelerator operation for the present section of the plurality of sections, in which section the vehicle is presently located, in accordance with the schedule of the recommended accelerator operation and the present position of the vehicle (S510).

Abstract:
PROBLEM TO BE SOLVED: To improve fuel consumption efficiency for a hybrid car for controlling the driving of an internal combustion engine and a motor according to a planned driving schedule. SOLUTION: An ECU 20 collects obtained electric energy obtained when the regenerative charging of a battery 9 is performed according to the traveling of a vehicle and required electric energy required by a motor 3, for each section, and makes a storage means store it. Afterwards, when the section where the obtained electric energy becomes larger than a first threshold or th section where the obtained electric energy becomes larger than a second threshold is included in the sections of the destination of traveling, the replanning of a control schedule is executed, and when the section where the obtained electric energy becomes larger than the first threshold or the section where the required electric energy becomes larger than the second threshold is not included in the sections of the destination of traveling, the replanning of the control schedule is inhibited.

Abstract:
A control apparatus for controlling a driving device of a vehicle, the driving device including a transmission system including (A) a non-step speed change portion which includes (a1) a differential device including a first rotary element connected to an engine, a second rotary element connected to a first electric motor, and a third rotary element connected to a transmission member, and (a2) a second electric motor provided in a power transmission path between the transmission member and drive wheels, and (B) a stepwise speed change portion; the control apparatus including a differential-state switching device which selectively switches the differential device to a differential state and to a non-differential state, and a rotation speed synchronization controller which performs a synchronization control of respective rotation speeds of the first, second, and third rotary elements to respective rotation speeds thereof after completion of a stepwise speed change control.
Abstract:
PROBLEM TO BE SOLVED: To provide an engine speed control device enabling appropriate control excellent in readiness of generated power or engine output torque. SOLUTION: Engine speed is determined according to power generation quantity (or engine output torque component required for the same) of a generator 102 or output torque of the engine 121. Consequently, in an embodiment, loss can be reduced by keeping engine speed in idling rotation speed control low without lacking torque used for power generation or sacrificing engine acceleration performance.
