Embodiment Construction

[0022] The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a diagram showing the arrangement of a hybrid vehicle to which the present invention is applied. Referring to FIG. 1, two power sources, namely an engine 11 and a motor-generator 12 are arranged in parallel to drive wheels, wherein the engine 11 (hereinafter also referred to as EG) is typically an internal combustion engine, and the motor-generator 12 (hereinafter also referred to as MG 12 ) is driven by electric power stored in the battery 19.

[0023] Torque output from the engine 11 is transmitted to the transmission 13 . Then, the torque is transmitted to drive shafts 15 and 15' through a differential device (differential) 14 serving as an output portion, and then to drive wheels 16 and 16' to drive the vehicle. Similarly, torque output from MG 12 is also transmitted through differential device 14 to drive shafts 15 and 15', and then ...

Abstract

The invention discloses a vehicle driving source control device, the driver control device is used for controling a engine (11) and a motor (12) as a driving source.The driving source control device comprises: a first motor-assisted model, which is used for shifting high-grade, controling the motor (12) output the first additional torque to compensat the engine torque fluctuation because of shifting.A second-motor assist model, which is used for shifting low- grade, controling the motor (12) output and accelerate a pedal opening (theta) corresponding to the second extra torque.

Description

technical field [0001] The present invention relates to a drive source control device for a vehicle. More specifically, the present invention relates to a drive source control device for a vehicle using an electric motor and an engine as drive sources. Background technique [0002] FIG. 8 shows the torque performance of the engine and motor generator (hereinafter referred to as electric motor or MG). The engine has a peak in a certain rev range and produces high torque. However, the engine produces a large amount of exhaust and the mileage per gallon is usually low. On the other hand, electric motors produce high torque in the low speed range. However, torque falls off in the upper rev range. [0003] A technique is known that, in so-called Parallel Hybrid Vehicles, utilizes the above-described differences in characteristics of drive sources to perform torque assist by an electric motor when the vehicle starts or accelerates. This torque assist makes the engine sound qu...
