Embodiment Construction

[0037] An embodiment will be explained with reference to the drawings. Such as figure 1 As shown, a hybrid vehicle 2 (which will be simply referred to as vehicle 2 hereinafter) includes two power generating machines, namely, an engine 4 and an electric motor 8 driven by electric power stored in a battery 6 . The engine 4 and the electric motor 8 arranged side by side drive the wheels of the vehicle 2 . Electric motor 8 is also used as a generator (motor generator MG).

[0038] An automated manual transmission (AMT) 12 serving as an automatic transmission is connected to the engine 4 via a clutch device 16 serving as a clutch. Specifically, the clutch device 16 is provided between the input shaft 14 of the automatic manual transmission 12 and the output shaft 10 of the engine 4 . The clutch device 16 engages and disengages between the output shaft 10 of the engine 4 and the input shaft 14 of the automatic manual transmission 12 to control transmission of engine torque Te to ...

Abstract

A control apparatus of a hybrid vehicle includes an automatic transmission (12), a clutch (16), a motor (8), a battery (6), a driving assist control device (26) performing a driving assist control by driving the motor to generate an assist torque, a gear shift assist control device (26) performing a gear shift assist control by driving the motor in response to a decrease of the engine torque caused by the disengagement state of the clutch, an SOC value detection device (48) detecting an SOC value, and a first mode switch device (24) switching an operation mode of the hybrid vehicle from a normal mode in which the driving assist control and the gear shift assist control are performed to a battery power preserving mode in which the driving assist control is prohibited and the gear shift assist control is permitted in a case where the SOC value is equal to or smaller than a first predetermined value.

Description

technical field [0001] The present invention generally relates to a control device for a hybrid vehicle. Background technique [0002] Hybrid vehicles including an engine operated by combustion energy of fuel and an electric motor operated by electric energy have been variously developed. The engine and the electric motor serve as power sources in a driving state of the hybrid vehicle. Hybrid vehicles have recently gained attention because, for example, noise and air pollution can be avoided by using an electric motor mainly as a power source in a normal driving state of the hybrid vehicle. In addition, disadvantages of electric vehicles, specifically, for example, insufficient mileage caused by a single charge of the battery or small torque generation resulting in difficulty in sudden acceleration, driving with a high load, and driving at high speeds, such disadvantages can be solved by The combined use of combustion energy operated engines is eliminated. [0003] Accord...
