摘要： A gas-sparing vehicle is achieved by a control system for a hybrid vehicle equipped at least with: a hybrid engine which includes at least a first rotary electric unit for deciding the rpm of the engine and a second rotary electric unit for deciding the driving force of the vehicle and which has power converting means connected to the output shaft of the engine; and electricity storing means. A vehicle driving power demand value Pv* is read and stored in memory in step S5100. The judgment results given in steps S5102 and S5104 are negative; therefore, the program proceeds to step S5106. In step S5106, the engine characteristic map shown in Fig. 8 is searched to decide an operating point (point C in Fig. 8) at which an engine 1 outputs the vehicle driving power demand value Pv* (curve B in Fig. 8) with highest efficiency, and an engine rpm command value Ne* is decided so as to update the data stored in memory. Further, in step S5108, the engine characteristic map shown in Fig. 9 is searched to decide a throttle opening target value θTH* which is the opening of a throttle valve 5 for maintaining the operating point (point C in Fig. 8), and an intake air volume adjusting amount TH is calculated based on the throttle opening target value θTH* to update the data stored in memory. In step S5122, the intake air volume adjusting amount TH is controlled by intake air volume regulating means 6, so that the engine 1 generates the output in exact accordance with the vehicle driving power demand value Pv*.

摘要： A high fuel consumption efficiency hybrid car is realized by the control system, on which at least a hybrid engine which includes at least a first rotating electric machine which determines the rotational speed of the engine and a second rotating electric machine which determines the driving force of the car, and includes a power converting means connected to the output shaft of the engine and a storage means are mounted. A car driving power request value pv* is read and stored in the memory in a step S5100. Further, as the negative judgements are made in steps S5102 and S5104, the processing is advanced to a step S5106. In the step S5106, an engine characteristics map shown in Fig. (8) is referred to and an operation point (Fig. 8, point C) at which the highest efficiency for the engine (1) to output the car driving power request value Pv* (Fig. 8, curve B) is obtained is determined and an engine speed command value Ne* is determined to update the data stored in a memory. Further, in a step S5108, an engine characteristics map shown in Fig. 9 is referred to, a throttle opening degree target value υTH* which is the opening degree of a throttle valve (5) for maintaining the operation point (Fig. 8, point C) is determined and a sucked air quantity regulation value TH is calculated in accordance with the throttle opening degree target value υTH* to update the data stored in the memory. Further, in a step S5122, as the sucked air quantity regulation value TH is controlled by a sucked air quantity regulating means (6), the output corresponding to the car driving power request value Pv* can be generated by the engine (1).
