Description

[0001]

The present invention is a technology for reducing the fuel consumption rate by automatically neutralizing the vehicle when the vehicle is stopped for a short period of time, thereby realizing reduction of resources and improvement of environmental pollution by reducing exhaust gas.

In addition, the shift bar automatically senses when the vehicle is stationary without actually moving, thereby realizing the actual shift, thereby preventing the troublesomeness and malfunction of the shift bar operation.

In the case of a vehicle called "automatic transmission", when the vehicle is stopped, the shift bar is shifted to the neutral position and the shift is neutralized, thereby reducing the fuel consumption and the wear rate of the brake pads.

Especially when the issue of environmental pollution due to exhaust gas is being emphasized as in recent years, the effect of reducing the exhaust gas by the neutral shift is further required.

However, in reality, the driver stops at the stop of the vehicle due to the reason that the operation of the shift bar is troublesome or the shift operation is incompletely recognized when the vehicle is stopped for a while, such as waiting for a signal.

In this case, the vehicle causes wear on the brake pads and fuel consumption which is comparable to that of running is caused even when the vehicle is at a standstill, resulting in fuel waste and air pollution caused thereby.

In the present invention, when the stopping time of the vehicle exceeds a predetermined time, the vehicle transmission senses it and automatically shifts to the neutral display, and the actual shift is performed only in the vehicle interior transmission in a state where the shift bar is located at the travel display position, It is possible to reduce the inconvenience of the bar operation, and ultimately to minimize the wear of the brake pads, to reduce fuel consumption, and to reduce air pollution.

Further, the mobile robot may further include an auxiliary sensing sensor for sensing whether the side brakes of the vehicle are operated, and the traveling rod may be controlled to move back and forth in response to a sensing signal of the auxiliary sensing sensor.

According to the present invention,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a specific configuration of the present invention will be described with reference to the embodiments illustrated in the drawings.

The automatic transmission according to the present invention has a structure that includes a transmission structure, that is, the transmission 1, the position transmitting member 4, and the shift bar 7, as shown in FIGS. 1 and 2, And further comprises a sensing sensor 30, a position sensing sensor 40, and a driving member 10.

First of all, the structure of the transmission 1 used in a general automatic transmission for an automobile is applied as it is. In brief, the transmission 2 has a connecting portion 2 and a connecting portion 2 connected to a position transmitting member, And a sensing sensor 3 for sensing the position of the sensor.

Since the structure of such a transmission 1 is a known technology, a detailed description thereof will be omitted.

The position transmitting member 4 serves to transmit to the transmission 1 whether or not the position of the speed change bar 7 to be described later and the position shifting state is transmitted to the transmission 1. One end is connected to the connecting portion 2 of the transmission 1 And the other end is connected to the speed change bar 7 and is pulled or pushed according to the position change of the speed change bar 7 to move the position of the connection part 2 of the transmission 1. [

For example, when the shift bar 7 is moved from the parking indication (P state) to the driving indication (D state) (hereinafter referred to as " driving indication "), the position transmitting member 4 is pulled by the corresponding distance, As the connection portion 2 of the transmission 1 is moved and the sensing sensor 3 senses a change in the position of the connection portion, the transmission is shifted corresponding to the travel indication.

In the present invention, the position transmitting member 4 is connected directly to the speed change bar 7 through a separate driving member 10 without being directly connected thereto.

The driving member 10 serves as an intermediary for connecting the position transmitting member 4 and the speed change bar 7 as described above and at the same time the position transmitting member 4 is moved independently of the positional shift of the speed change bar 7 And, as a result,

And a moving rod (14) linearly moved back and forth from the driving body by a driving force of the driving body and a driving body (12) generating a driving force again.

The driving member 10 is connected to the lower end of the speed change bar 7 so that the driving member 12 is moved together with the entire speed change bar 7 while the position of the speed change bar 7 is fixed Only the moving rod 14 is linearly moved forward and backward by the operation of the drive main body 12 in Fig.

At this time, an end portion of the position transmitting member 4 is connected to the end of the moving rod 14. By this structure, the position transmitting member 4 is moved along with the driving member 10 when the position of the speed change bar 7 is moved And transmits the transmission signal to the transmission 1,

Even when the position of the transmission bar 7 is fixed, the transmission member can be moved back and forth only through the operation of the driving member 10 to transmit the transmission signal to the transmission.

At this time, the moving rod 14 is moved only by the same distance as the distance at which the speed change bar 7 is moved between the driving display position and the neutral display position,

With this structure, when the moving rod of the driving member is advanced in the state that the transmission bar 7 is positioned at the traveling display position, the position transmitting member 4 is also moved to the same length, So that the shift from the driving display to the neutral display can be performed.

That is, even if the transmission bar 7 is positioned at the driving display position, the transmission shifts to the neutral display.

The control unit 20, the stop time sensor 30, the position sensor 40, the auxiliary sensor 50, and the control unit 20 may be further included in the present invention. .

The control unit 20 is connected to each sensor and a sensing sensor 3 of the transmission 1 to calculate a signal transmitted from each sensor to control the operation of the transmission and the driving member 10 .

Such a control unit can be applied to any structure as long as it can perform electrical calculation and control like a transmission control body used in a conventional automatic transmission.

The stopping time detecting sensor 30 detects the stopping of the vehicle during running, and is further divided into a braking detecting sensor 32 and a stopping time detecting sensor 34.

The brake detection sensor 32 senses whether the braking device, that is, the brake, is actuated for stopping the vehicle. When the driver depresses the brake pedal to apply the braking force, the braking sensor 32 senses the braking force, send.

Then, the stop time sensor 34 senses the stop state of the vehicle when the stop state is over a predetermined time after the stop of the vehicle by the braking device and sends a stop time hold signal to the controller 20.

For example, when the time when the driver depresses the brake 5 is 3 seconds or more while the automobile is stopped, the signal is sent to the control unit.

If one of the sensors can simultaneously detect whether the braking device is operating and the stopping time, the stopping time detecting sensor 30 may be a sensor having an integrated function of the stopping time detecting sensor 34 and the braking detecting sensor 32 Can be implemented.

The stop time monitoring sensor 30 may further include various sensing methods as long as it can detect that the vehicle is stopped for a predetermined time or longer, such as a sensor for detecting whether the throttle valve of the vehicle is operated or not.

In addition, the position sensing sensor 40 senses whether the speed change bar 7 of the stopped automobile is located at the driving display position and transmits the position sensing signal to the control unit 20. The limit sensing switch 40, So that the transmission bar 7 can be detected when it is positioned at the corresponding point.

The auxiliary sensing sensor 50 senses whether the parking brake 8 is operated and then transmits the signal to the control unit 20 before starting the vehicle again after stopping.

For example, if the parking brake 8 is operated and the braking is maintained before starting, it senses the braking operation and cuts off the operation of the driving member.

The driving member 10 described above is connected to the control unit 20 so that the movement of the moving rod in the forward and backward directions is controlled according to whether the stopping time detecting sensor 30, the position detecting sensor 40, .

Hereinafter, the automatic transmission according to the present invention will be described.

The automatic shifting method is largely composed of a stop state sensing step S100, a lever position sensing step 200, a first shift signal output step S300 and a neutral shift step S400 as shown in FIG.

First, the stopping state detection step S100 is a step of determining whether the vehicle being driven is stopped by being braked by the braking device and the stopping state has been exceeded for a predetermined period of time. This is performed by the stopping time detecting sensor 30,

Specifically, when the driver depresses the brake pedal 5 for waiting for a signal during driving, the braking sensor 32 senses the brake pedal 5 and sends a corresponding sensing signal to the control unit 20, And sends an operation signal to the time detection sensor 34.

Then, when the vehicle is completely stopped for a predetermined time or longer, the stopping time detecting sensor 34 detects the stopping time and transmits the detection signal to the control unit 20.

Accordingly, the control unit 20 recognizes that the vehicle is in a stopped state for a predetermined time after being braked.

The lever position sensing step S200 is a step of determining whether the shift bar 7 is positioned at the driving display position in a state where the vehicle is completely stopped. The lever position sensing step S200 is performed by the position sensing sensor 40, 20).

Accordingly, the control unit 20 recognizes that the vehicle is in a state in which the transmission bar 7 is stationary for a certain period of time in a state where the transmission bar 7 is positioned at the driving display position.

For reference, the lever position sensing step S200 may be performed after the stop time detection or before the stop time detection process after the vehicle is completely stopped.

In the first transmission signal output step S300, when the state of the vehicle is matched with the corresponding condition, that is, when the vehicle is completely stopped for a predetermined time or longer and the transmission bar is positioned at the driving display position, (1) to a neutral speed change signal,

When the control unit 20 simultaneously receives the sensing signals of the upper and lower sensors and sends an operation signal to the driving member 10, the driving body 12 is operated as shown in FIG. 4, Finally, the position transmitting member 4 is also moved forward.

At this time, as described above, since the moving rod 14 is moved by the same distance as the moving distance between the traveling display point and the neutral display point, the connecting rod 4 finally reaches the connecting point between the position transmitting member 4 and the moving rod 14 It is only moved from the driving display point to the neutral display point.

For example, if any one of the detection signals of the sensors is not input to the control unit, that is, the driver directly shifts the shift bar 7 to the neutral display position, or if the brake pedal is released from the brake pedal The first transmission signal output step S300 does not proceed.

In the neutral shifting step S400, when the position transmitting member is moved to the neutral display position by the driving member 10 in the first shifting signal output step S300, the connecting portion 2 of the transmission 1 moves The detection sensor 3 of the transmission 1 senses the moving distance of the connecting portion 2 and the actual transmission shifts to the neutral state through the transmission 1. [

That is, the shift bar 7 is located at the travel display position, the actual shift by the transmission 1 is converted into the neutral state.

In order to start the vehicle again, the braking release sensing step S500, the second shift signal output step S600, and the shift step S700 are performed as shown in FIG.

First, the braking release detection step S500 is a process of detecting whether the braking force of the vehicle is released by the stopping state detection sensor 30 before starting. When the driver's foot is separated from the brake pedal, the stopping state detection sensor 30 detects the braking release And transmits the detection signal to the controller 20.

If the parking brake 8 is operated in the stopped state, the auxiliary detecting sensor senses the deactivation state of the parking brake 8 and transmits the signal to the control unit 20.

Accordingly, the control unit 20 is in a state in which the control unit 20 recognizes that the braking force of the vehicle is all released by the detection signals by the sensors.

The second transmission signal output step S600 is a process for giving a signal for shift indication to the transmission 1 via the driving member 10 when the braking force of the vehicle is released,

When the control unit 20 sends an operation signal to the driving member 10, the moving rod 14 is retracted rearward, and thereby the position transmitting member 4 is also moved backward.

That is, the moving rod 14 and the position transmitting member 4 are operated in the direction opposite to the first shift signal output step S300.

At this time, since the moving rod 14 is moved only by the distance equal to the moving distance between the traveling display point and the neutral display point, the connecting point between the position transmitting member 4 and the moving rod 14 is also neutral It is only moved from the display point to the driving display point.

For reference, since the second shift signal output step S600 is performed only when the braking is completely released, the second shift signal output step S600, when the driver before departure has not yet been released from the operation of the parking brake, It will not proceed.

In the traveling shift step S700, when the position transmitting member is moved to the driving display position by the driving member 10 in the second transmission signal output step S600, the connecting portion 2 of the transmission 1 moves The detection sensor 3 of the transmission 1 senses the moving distance of the connecting portion 2 and the actual transmission shifts to the traveling indication state through the transmission 1. [

That is, the shifting bar is not moved even in the process of actual shifting by the driving display.

In other words, when the vehicle is stopped for a predetermined period of time and the shift bar is positioned at the driving display position, the actual shift by the transmission 1 is neutralized without moving the shift bar 7 to the neutral display position. Display.

Therefore, the shift to the neutral display is automatically performed each time the vehicle is stopped by the signal waiting or the like, thereby achieving the fuel saving effect and the brake wear prevention effect.

Since the actual shift is converted into the travel display while the position of the shift bar 7 is fixed to the travel display position even when the vehicle starts, even if the driver immediately before the start looks at the shift bar with the naked eye, the shift bar malfunctions There is no concern.
