Description

Automatic gear shift of automobile

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic transmission of a vehicle for automatically shifting a gear according to a traveling speed. More particularly, in a typical vehicle having a manual shift function, a separate cylinder and a motor are mounted on a transmission and a clutch. In addition, the present invention relates to an automatic transmission of an automobile, which is configured to be automatically controlled electronically by a control unit so that a gear can be automatically shifted without a driver's operation.

In general, the vehicle is to make the configuration of the transmission in order to maintain and convert the driving speed of the vehicle properly according to the engine rotation speed, such a transmission of the vehicle is a manual transmission using a gear operation method. It is widely used.

Therefore, the conventional manual transmission of the conventional vehicle is a configuration and operation principle as shown in Figure 1 first step on the clutch pedal 10 to supply the operating oil from the reservoir tank 20 to the transmission line 30. The pressure of the supplied hydraulic oil is increased by the master cylinder 40 to the release cylinder 50, and the release cylinder 50 is spaced apart from the clutch disc 70 from the flywheel 60 by the boosted hydraulic oil. The engine (E) power is cut off, and the shift lever (80) is operated by the driver's manual operation while the engine (E) power is blocked.

However, in the conventional manual transmission as described above, the driver should directly determine the engine rotational speed of the vehicle according to the traveling speed, and the gear should be manually shifted by the determination, which is a skill for the drivers. Not only was it a problem that was not suitable for a novice driver to use it, but even a skilled driver had a considerable discomfort that accumulated fatigue due to frequent manual shifts.

On the other hand, as a solution to the problem of the manual transmission in recent years, the automatic transmission of the vehicle has been developed and widely commercialized.

However, such a conventional automatic transmission adopts a converter type in which a torque converter (fluid clutch or hydraulic clutch) is mounted on the flywheel of the vehicle engine, which increases the hydraulic pressure by the engine power and increases the hydraulic pressure. This is how the gears are automatically shifted.

However, the automatic transmission has no choice but to rely on the engine power of the vehicle to generate the hydraulic pressure for gear shifting. Accordingly, the rotation speed of the engine is increased, and thus, a considerable power loss problem is generated. Nevertheless, the problem of shortening the engine life due to excessive fuel consumption due to such power loss has always existed.

Therefore, the present invention was devised to solve the general problems of the conventional vehicle transmission (manual and automatic);

An object of the present invention is to form an automatic control means, an intermittent part and an automatic transmission part in a conventional manual transmission, and electronically (program) according to various input information (engine rotation signal, vehicle driving signal, transmission lever position signal, brake signal). It is equipped with a control unit that performs the control function so that the gear can be automatically shifted without the driver's separate operation, and the automatic speed change function properly connects and maintains the running speed of the vehicle according to the engine rotation speed. Of course, to solve the inconvenience caused by manual gear shifting to reduce the fatigue of the driver is to provide an automatic transmission of the car.

On the other hand, another object of the present invention is to increase the power efficiency of the engine by the automatic transmission function by the cylinder, the motor and the control unit composed of the intermittent portion and the automatic transmission portion to reduce the fuel consumption rate and at the same time prevent overload of the engine power It is to provide an automatic transmission of a car to extend the service life of the engine.

And a vehicle speed sensor, an engine speed sensor, a brake sensor, and an accelerometer to sense the vehicle speed, the engine rotation speed, the brake position, and the accelerator state to control the speed control part and the transmission part, and to automatically shift gears. This is accomplished by forming a control unit.
