Referring to
The wheels 51 and 52 include front wheels 51 and rear wheels 52, and the driving system 60 transmits turning forces to the front wheels 51 or rear wheels 52 to move the vehicle 100 forward or backward thereof. The driving system 60 may employ a motor that produces the turning force from electrical power supplied from a storage battery or a combustion engine that burns a fuel to create the turning force.
The doors 71 and 72 are attached onto the left and right sides of the main body 1, and opened for entering and exiting the vehicle 100 and closed for shielding the internal of the vehicle 100 from the outside.
The front glass 30, also termed as a windshield glass, is placed on the top portion front of the main body 100 for the user within the vehicle 100 to obtain visual information in front of the vehicle 100.
The side mirrors 81 and 82 include a left side mirror 81 and a right side mirror 82 placed on the left and right sides of the main body 1, respectively, for helping the driver obtain views behind and to the side of the vehicle 100.
In addition, the vehicle 100 may include detection devices including a proximity detector for detecting an obstruction or other cars in the back or to the side of the vehicle 100, a rainfall detector for detecting precipitation and whether it is raining, etc.
Referring to
The AVN input 142 may be manipulated by the user to enter a command to control the AVN device 140.
The AVN input 142 may be implemented in a hard-key type at an area close to the AVN display 141, as shown in
A speaker 143 may be provided in the vehicle 100 to output sounds which are involved in performing the audio, video, and/or navigation function.
A dashboard 10 may include a steering wheel 12 in front of the driver's seat 21, speed gauge 161b and rpm gauge 161c indicating current speed and rpm of the vehicle 100, respectively, behind the steering wheel 12, and further include a cluster display 161a for displaying information related to the vehicle 100 to a digital screen.
Furthermore, a cluster input 162 is placed on the steering wheel 12 to receive a selection about information to be displayed on the cluster display 161a from the user. The cluster input 162 may be easily manipulated by the user behind the wheel, and thus may receive not only the selection of information to be displayed on the cluster display 161a but also a command to control the AVN device 140.
In an exemplary embodiment of the present invention, a touch input 12b may be provided on the rim 12a of the steering wheel 12.
The touch input 12b may be disposed on the front of the rim 12a, and when the rim 12a is wrapped with a separate cover, the touch input 12b may be attached onto the internal side or the top portion of the cover as a capacitance touch panel.
The touch input 12b may be attached onto the front of the rim 12a as a single or a successive plurality of capacitance touch panels.
The touch input 12b may receive a touching input from the driver wrapping the rim 12a.
In an exemplary embodiment of the present invention, the vehicle 100 may further include a touch controller for determining a touching input received through the touch input 12b from the driver and activating or deactivating a touch area for manipulation of the touch input 12b based on the touching input.
The touch input 12b may be easily manipulated by the user behind the wheel, and thus receive a selection command about information to be displayed on the cluster display 161a or the AVN display 141, a control command to control the cluster display 161a or the AVN device 140, and other various instructions to operate internal components of the vehicle 100. The touch area for manipulation refers to a touch input area, in which to enter various instructions to manipulate internal components of the vehicle 100.
When the touch input 12b is implemented as a capacitance touch panel, the touch controller may determine whether a touching input is entered by the driver based on a change in capacitance of the touch panel. The touch controller may also determine whether a touching input from the driver is a palm touching input or a finger touching input based on a touch area of the touch input 12b, in which the touching input has been entered by the driver.
When the touch area of the touch input 12b, in which the touching input has been entered by the driver, is greater than a predetermined threshold area, the touch controller may determine that the touching input is a palm touching input, and when the touch area is less than the threshold area, the touch controller may determine that the touching input is a finger touching input.
In the instant case, the touch controller may determine the touching input signal using a low pass filter to determine the palm touching input and a high pass filter to determine the finger touching input.
When the touching input of the driver is determined to be the palm touching input, the touch controller may set the touch area to a blob area a1, set up touch areas for manipulation a2, a3 based on the blob area a1, and activate the touch areas a2, a3 for manipulation.
For example, the touch areas a2, a3 for manipulation may be two partial areas a2, a3 of the touch input 12b a predetermined offset d away from the blob area a1. The predetermined offset d may be a predetermined value in a manufacturing stage, a value manually entered by the driver beforehand, or a value set by learning of the touch controller.
As the touch controller activates the touch areas a2, a3 for manipulation, the driver may be able to enter various commands into the touch areas a2, a3 for manipulation to operate internal components of the vehicle 100.
Meanwhile, as shown in
By deactivating the touch area a3 for manipulation in the lower area clockwise from the blob area a2, unnecessary power consumption may be reduced.
On the other hand, as shown in
The touch controller may set a new offset by learning about points within the touch areas a2, a3 for manipulation, at which touching inputs have been received.
Referring to
For example, when a touching input is received at a point p in the touch area a2 for manipulation above the blob area a1, the touch controller may set a distance from a center point of the blob area a1 to the point p, at which the touching input has been received, to the new offset d′.
The offset d may be expanded or reduced depending on the point, at which the touching input has been received, and accordingly, the touch areas a2, a3 for manipulation may also be changed (into a2′, a3′, respectively).
Furthermore, referring to
For example, when the touching input is received at the plurality of points p1˜p4 in the touch area a2 for manipulation in the upper area from the blob area a1, the touch controller may set a distance from the center point of the blob area a1 to the center point pc of the plurality of points p1˜p4, at which the touching input has been received, to the new offset d′.
Such a newly set offset d′ may be stored in a memory to be used by the controller in a subsequent process of setting up a touch area for manipulation. The touch areas a2, a3 for manipulation may be changed into a2′, a3′, respectively.
Although an occasion when the driver makes a touching input on the right side of the steering wheel 12 was referred to as an exemplary embodiment in the above embodiment, the driver may make a touching input with his or her left hand on the left side of the steering wheel 12, in which case, the touching input is received in a touch area for manipulation in an upper area clockwise from the blob area, and the touch controller may deactivate a touch area for manipulation in a lower area counterclockwise from the blob area. On the other hand, when the driver may make a touching input with his or her right hand on the left side of the steering wheel 12, the touching input is received in a touch area for manipulation in a lower area counterclockwise from the blob area, and the touch controller may deactivate a touch area for manipulation in the upper area clockwise from the blob area.
Besides, the driver may make touching inputs at any points, so the present invention is not limited to the aforementioned embodiment.
In the meantime, when no touching input has been received in an activated touch area for manipulation for over a predetermined first reference time period (e.g., 5 seconds), the touch controller may activate even the remaining touch area(s) for manipulation that has (have) been deactivated.
However, when any touching input has not been received, i.e., there has been no palm grip in the blob area for over a predetermined second reference time period (e.g., 10 seconds), all the touch areas for manipulation are deactivated. It may be determined whether there is a new touching input received through the touch input 12b again from the driver, and a blob area may be set up again based on a touch area of the input device 12b, in which the touching input has been received.
The touch controller may be implemented with a memory for storing an algorithm to control operation of the touch input 12b or control components in the vehicle 100 based on a touching input received through the touch input 12b or data of a program representing the algorithm, and a processor or for performing the aforementioned operation using the data stored in the memory. The memory and the processor may be implemented in separate chips. Alternatively, the memory and the processor may be implemented in a single chip.
At least one component may be added or deleted to correspond to the performance of the components of the vehicle 100. Furthermore, it will be obvious to the ordinary skilled people in the art that the relative positions of the components may be changed to correspond to the system performance or structure.
Some components of the vehicle 100 may be implemented in software, or hardware including Field Programmable Gate Arrays (FPGSs) and Application Specific Integrated Circuits (ASICs).
A method for controlling the vehicle 100 including the steering wheel In accordance with various exemplary embodiments of the present invention will now be described with reference to
Since components of the vehicle 100 as will be mentioned below are the same as those of the vehicle 100 including the steering wheel 12 as described with reference to
First, referring to
The detecting of the touching input of the driver may include determining, by the touch controller, the touching input based on a change in capacitance of a capacitance touch panel when the touch input 12b is implemented by the capacitance touch panel. For example, when the change in capacitance is greater than a predetermined threshold, the touch controller may determine that there has been a touching input.
The determination of whether the touching input is a palm touching input may be made by the touch controller based on the size of a touch area of the touch input 12b in which the touching input has been received. For example, when the touch area, in which the touching input has been entered by the driver, is larger than a predetermined threshold area, the touch controller may determine that the touching input is a palm touching input, and when the touch area is less than the threshold area, the touch controller may determine that the touching input is a finger touching input.
The determination of whether the touching input is a palm touching input of the driver may include having the touching input signal received through the touch input 12b pass the low pass filter to detect a palm touching input signal, or pass the high pass filter to detect a finger touching input signal.
When the touching input is determined to be a palm touching input in 1112, the touch controller sets the detected touch area to a blob area in 1113. However, when the touching input is not determined to be a palm touching input in 1112, the touch controller performs a procedure of receiving a touching input of the driver in 1111 and determining whether a touching input is a palm touching input until the ignition of the vehicle is turned off in 1121.
Setting the detected touch area to a blob area may include, for example, setting an area formed by edge portions of the touch area to the blob area, or extracting center coordinates of the touch area and setting an area formed by a predetermined figure centered on the center coordinates to the blob area, without being limited thereto.
The touch controller then sets up a touch area for manipulation based on the set blob area and activates the touch area for manipulation, in 1114.
The touch area for manipulation may be one or more areas located as far as a predetermined offset from the blob area.
For example, the touch controller may set two areas an offset away from the blob area in opposite directions to the touch area for manipulation.
The predetermined offset may be a predetermined value in a manufacturing stage, a value manually entered by the driver beforehand, or a value set by learning of the touch controller.
When the touch controller activates the touch area for manipulation, the driver may be able to enter various commands to control internal components of the vehicle 100. For example, the driver may select a content displayed on the AVN display 141 or the cluster display 161a by making a touching input on the touch area for manipulation.
The touch controller then determines whether a touching input is made by the driver in the touch area for manipulation, in 1115.
The determination of whether a touching input is made by the driver may include determining a touch area for manipulation in which a touching input is made, when a plurality of touch areas for manipulation are set up.
When a touching input is received from the driver in 1115, the touch controller changes an offset (i.e., learns an offset) based on a point at which the touching input has been received, and deactivates other touch area(s) for manipulation, in which no touching input has been made, than the touch area for manipulation, in which the touching input has been made, in 1116. How to change an offset was described above with reference to
The touch controller may keep the activated touch area for manipulation as it is when there are continuous touching inputs in the activated touch area for manipulation, or may activate a deactivated touch area in 1119 when there has been no touching input in the activated touch area for manipulation for the first reference time period (i.e., the first reference time period has elapsed without any touching input in 1117), allowing all the plurality of touch areas for manipulation to be able to receive touching inputs.
The activation of the deactivated touch area in 1119 may be performed until the second reference time period, which is greater than the first reference time period, has not elapsed.
When the second reference time period has elapsed in 1117, 1118 without detection of any touching input in the activated touch area for manipulation in 1115, the touch controller determines that there would be no touching input to the touch input 12b and deactivates the activated touch area for manipulation, 1120.
Even while the touch area for manipulation is deactivated, the touch input 12b may still detect whether there is a touching input of the driver until the ignition is turned off in 1121, and may change the blob area by detecting another palm touching input in 1112, as described above.
The exemplary embodiments of the present invention may be implemented in a form of recording media for storing instructions to be conducted by a computer. The instructions may be stored in a form of program codes, and when executed by a processor, may generate program modules to perform operation in the exemplary embodiments of the present invention. The recording media may correspond to computer-readable recording media.
The computer-readable recording medium includes any type of recording medium having data stored thereon that may be thereafter read by a computer. For example, it may be a ROM, a RAM, a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, etc.
