Tandem Diesel Engine-Electric Vehicle Driving Device and Its Application Method

Abstract

The invention relates to the field of a combination control device for more than two different prime motors and specifically relates to a series type diesel engine-motor automobile driving device. The series type diesel engine-motor automobile driving device comprises a traction motor (7), a speed reducer (8) and wheels (9), and is characterized by further comprising a whole automobile controller (1), an engine electric control unit (2), an engine (3), a starting and generating integrated motor (4), a battery (5) and a motor driver (6), wherein the whole automobile controller (1) is respectively connected with the engine electric control unit (2) and the motor driver (6) through a communication line, and the engine electric control unit (2) is connected with the engine (3) through a communication line. A use method of the series type diesel engine-motor automobile driving device is characterized by comprising five steps. The series type diesel engine-motor automobile driving device is simple in structure and accurate in control; the oil-saving ratio of the engine is increased; and the discharging of waste gas is reduced.

Description

technical field [0001] The invention relates to the field of joint control devices for two or more different prime movers, in particular to a serial diesel engine-motor vehicle driving device and a method for using the same. Background technique [0002] With the improvement of environmental protection requirements and the gradual deepening of the concept of energy saving, new hybrid electric vehicles continue to emerge. The so-called hybrid power system is a hybrid power system composed of an internal combustion engine and an electric motor in series, and the energy of the internal combustion engine is converted into electrical energy by a generator. To drive the electric motor, the internal combustion engine always works in an efficient working area. According to the type of internal combustion engine, hybrid power includes gasoline engine-motor, diesel engine-motor, supercharged diesel engine-motor, etc. For gasoline engine-motor hybrid system, since it can start and stop...

AI Technical Summary

Problems solved by technology

However, for the supercharged diesel engine-motor, because the supercharged diesel engine cannot start and stop frequently, it must keep idling, which will also consume a certain amount of energy, and the energy consumption of idling in the case of continuous work cannot be ignored
