Vehicle automatic gear shift display
The present invention relates to an automatic transmission shift display device of a vehicle, and more particularly, to detect a shift state inside an automatic transmission of a vehicle and display a shift state of a transmission to a driver, thereby improving a sense of unity between the driver and the vehicle. The present invention relates to an automatic transmission shift display device of a vehicle.
In general, the transmission of the vehicle is installed between the clutch and the propulsion shaft to appropriately shift the engine rotation to match the driving power of the vehicle, thereby increasing the rotational force of the propulsion shaft or changing the engine to a high-speed rotation, and the engine at no load. It is a device that plays a role in keeping the vehicle or reversing the car.
On the other hand, the transmission of the vehicle is required to be lightweight, robustness, operability, quietness, convenience, etc., it is ideal that the transmission ratio can be changed continuously or automatically.
The transmission can be divided into two types, manual and automatic. The manual transmission is also called a selective gear transmission, and the type of transmission (T / M) used in the front engine rear wheel drive (FR) vehicle, It can be roughly classified as a transaxle (T / A) used in front engine-drive (FF) vehicles.
Unlike the manual transmission, the automatic transmission does not have a clutch, and the shift is automatically performed according to the accelerator pedal and the speed of the vehicle. The main components include torque converter, clutch, brake, planetary gear, and hydraulic control. Devices, electronic control devices and the like.
When the driver of the manual transmission operates the shift lever in positions corresponding to 1, 2, 3, 4, and neutral and reverse, the shift is performed in such a manner that the gears in the transmission engage with each condition. Is done.
Therefore, the driver must select a shift suitable for the driving state of the vehicle by operating the shift lever at the time of shifting the vehicle, and the driver forms a sense of unity with the vehicle through the shift operation.
Therefore, a vehicle employing a manual transmission is preferred by a driver who enjoys sensational driving, and the vehicle can be driven in a state in which the driver remembers the shift state of the transmission, thereby improving the ability to cope with unexpected accidents during driving.
In detail, the automatic transmission can be driven while grasping the relationship between the rotational force and the rotational speed of the output shaft of the transmission when driving downhill or uphill of the vehicle, thereby improving the ability to cope with sudden accidents. Have
The automatic transmission selects any one of the P-R-N-D-2-L modes as an operation of moving the shift lever back and forth, and in a general forward driving state, the shift lever is positioned in the drive (D) mode to drive the vehicle.
In the state where the shift lever is positioned in the drive (D) mode, the shifting speed is shifted three speeds forward or four speeds automatically according to the amount (opening) of the accelerator pedal, and is fixed at two speeds forward in the idle state. It is designed to reduce the slip and vibration of the car, and when it starts to kick, it is kicked down to 1st speed and shifted to 1st speed, 2nd speed and 3rd speed.
The kick-down is performed when the accelerator pedal is depressed more than 85% while driving at the 4th, 3rd, 2nd, and 1st speeds, and the driving force of the propulsion shaft is increased by shifting the low gear.
Since the automatic transmission automatically determines the speed of the vehicle and the rotational force of the propulsion shaft in accordance with the amount of pedaling in the driving state, the supply and demand of vehicles equipped with automatic transmissions have recently increased.
Unlike the manual transmission, the automatic transmission has a structure in which the driver does not accurately grasp the gear state of the transmission. Accordingly, the driver tends to drive the vehicle by a simple operation as compared to a vehicle equipped with the manual transmission.
In addition, since the automatic transmission cannot accurately grasp the transmission state of the transmission, it is difficult to consider the operating state of the engine brake or the maximum rotational force of the propulsion shaft when driving downhill or on an uphill road.
In other words, the driving conditions of the vehicle, that is, the inclination of the road surface, the degree of bending, etc. are not considered, and there is a problem in that the vehicle must be driven simply by detecting the pedal effort of the pedal.
On the other hand, while driving the vehicle, it may be desirable for the driver to drive the vehicle by paying attention to the output and the speed of the vehicle. There is a difficult problem.
The present invention has been made to solve the above problems, and an object of the present invention is to provide an automatic transmission shift display device for a vehicle so that the driver can visually check the shift state inside the transmission of the vehicle to which the automatic transmission is applied. .

30: gear shift detection sensor
In order to achieve the above object, an automatic transmission shift display apparatus of a vehicle according to the present invention includes gear shift detecting means for detecting a gear shift stage inside an automatic transmission; It characterized in that it comprises a gear shift display for displaying the gear shift selected through the gear shift detecting means.
In the case where the automatic transmission is an electronically controlled gear shift stage operated by a control unit (TCU), it is preferable that the gear shift detection sensor uses a control unit (TCU).
In addition, the gear shift display unit is preferably displayed using an LED.
Hereinafter, the configuration of an automatic transmission shift display device for a vehicle according to the present invention will be described in detail with reference to the accompanying drawings.
The automatic transmission means that the operation of the transmission for transmitting the driving force by changing the rotational speed and rotational force transmitted from the engine is automatically performed by the shift pattern.
The automatic transmission can be largely divided into a torque converter, an operating mechanism, a planetary gear, a hydraulic control mechanism, and an electronic control device. The automatic transmission rotates an input shaft by receiving power of an engine using a fluid clutch. The gear shift is performed by changing the hydraulic circuit in the hydraulic control mechanism automatically according to the speed and load so that the planetary gear device is operated.
The automatic transmission has a complicated structure and is difficult to manufacture, but does not require a clutch operation, and has a long body life due to soft power transmission and excellent ride comfort.
On the other hand, the automatic transmission may be divided into hydraulic and electronically controlled, the electronically controlled control unit (TCU) information on the vehicle running state, such as the throttle valve opening, engine speed, vehicle speed from the sensors attached to the engine and the transmission (TRANSAXLE CONTROL UNIT)) is an automatic transmission that makes hydraulic operation, gear shift and damper clutch electrically after input and calculation.
The electronically controlled automatic transmission is more comfortable to ride than the hydraulically controlled automatic transmission, the fuel economy is excellent, and the fault is detected by the circuit and the self-diagnosis function which stops the driving signal by fixing it at three speeds by the self-correction function even in the event of a failure. Has the advantage.
The shift operation function of the automatic transmission is a shift display function when the driver shifts the shift lever manually. There are six types of PRND-2-L, and the most suitable for the engine performance and driving situation. There is a driving mode that enables shifting, and it has sufficient reliability and durability in response to the power performance of high-powered engines, economy mode for low fuel consumption and low noise, power mode for smoother driving and slippery road surface. Three driving modes have been added.
In the parking mode P, each operating element is not fully operated, and therefore the engine output is not transmitted to the output shaft.
Since the output shaft is mechanically completely fixed by the packing mechanism, the vehicle does not move forward and backward, the engine can be started, and some vehicles do not have a start key when the vehicle is not in the parking mode.
The reverse (R) mode is used when the vehicle reverses, and must be used after the vehicle stops, and the engine cannot be started in the reverse mode.
In the neutral mode, the engine output is not transmitted to the output shaft, and the engine can be started.
The driving (D) mode is a three-speed forward or a four-speed shift is automatically made according to the amount of pedaling (throttle opening) and the vehicle speed of the accelerator pedal. When shifting to the 4th forward, it automatically shifts according to the shift pattern.
In addition, the drive (D) mode is fixed at two speeds in the idle state to reduce the sliding and vibration phenomenon of the car, and when the oscillation is kicked down to one speed, the speed changes to the first, second and third speeds.
In the drive (D) mode, the kick-down is performed when the accelerator pedal is depressed about 85% or more while driving at the 4th, 3rd, 2nd, and 1st speeds, and the driving force is increased by shifting the low gear, thereby increasing the driving force. .
In addition, the damper clutch is automatically operated when entering the D / C operating region at the second speed, and the engine brake is not operated at the drive D mode 1 speed.
In the second mode, the shift is automatically performed in the first and second speed sections, and the shift to the third speed is not performed.
In addition, the engine brake does not operate in the 2 mode 1 speed, and it is used when driving on an ice road or a curved road.
In the lock-up (L) mode, the speed is shifted from 2 speed to 1 speed, but is not shifted from 1 speed to 2 speed or 3 speed. That is, it is fixed at 1 speed.
In addition, in the lock-up (L) mode, the start is made at one speed and the engine brake is operated. Therefore, it is mainly used when an engine brake is required, such as a continuous downhill.
The above is a description of a shift function for a general shift operation of an automatic transmission to which the present invention is applied, and is a description to help an understanding of the automatic transmission to which the present invention is applied.
As described above, the gear shift stage is automatically selected in the drive (D) mode, the 2 mode, and the lock-up (L) mode of the automatic transmission, and the present invention detects the gear shift stage that is automatically variable and selected. It provides a set of devices for marking the gear shift.
