DETAILED DESCRIPTION
An exemplary embodiment of the present disclosure will hereinafter be described in detail with reference to the accompanying drawings.
FIG. 1 is a configuration diagram of a driver recognition system for a vehicle according to an exemplary embodiment of the present disclosure.
As illustrated in FIG. 1, the driver recognition system for a vehicle includes a camera 10, a central processing unit 20, a control unit 30, a control execution unit 40, and an operator 50.
The camera 10 takes an image of driver's shoes. The camera 10 may be mounted on a door of a driver's side or a lower side of a dashboard of the driver's side. The position of the camera 10 may be changed so as to easily take the image.
The central processing unit 20 receives image information from the camera 10, and recognizes the shoes in accordance with the received image information. Recognition of the shoes includes a process of classifying the shoes and determining the driver. The shoes may be determined as one group among groups classified as sneakers, shoes, and high heels which may be set by a user in advance. Information on shoes and an owner of the shoes are inputted into the central processing unit 20 in advance, through which the driver can be accurately recognized. Here, the central processing unit 20 generates a signal in accordance with the determined shoes and information on the driver.
The central processing unit 20 includes a determiner 22 and a deliverer 24. The determiner 22 is a section that classifies the shoes and determines the driver. The deliverer 24 generates a signal in accordance with the classified shoes and information on the driver and delivers the generated signal.
The control unit 30 receives the signal delivered from the deliverer 24, and outputs a control command so as to set the driving environment and the driving mode in accordance with the received signal. The control unit 30 may be a general electronic control unit (ECU) that controls electronic apparatuses, such as a navigator, a DMB, an audio system, etc. of the vehicle.
The control execution unit 40 sets the driving environment and the driving mode in accordance with the control command received from the control unit 30. The control execution unit 40 includes an actuator that adjusts angles of an accelerator pedal and a brake pedal or adjusts a position of a seat, a safety belt, or a handle. The control execution unit 40 further includes a device that sets sensitivity of the accelerator pedal, the brake pedal, the handle so as to switch the driving mode. The driving mode is selected according to the classified group of the shoes. For example, in the case of the shoes, the driving mode may be set as an echo mode, in the case of the sneakers, the driving mode may be set as a sport mode, and in the case of the high heels, the driving mode may be set as a safety mode. Setting the echo mode, the sport mode, or the safety mode may be defined by the user in advance.
The operator 50 sets all devices, such as the accelerator pedal, the brake pedal, the seat, the safety belt, and the handle that are operated by the control execution unit 40.
FIG. 2 is a flowchart of a driver recognition method for a vehicle according to another exemplary embodiment of the present disclosure.
As illustrated in FIG. 2, when the driver recognition system for a vehicle is operated (S100), the central processing unit 20 recognizes shoes in accordance with an image of the shoes taken by the camera 10 (S110), and determines classification of the shoes in accordance with information on the recognized shoes (S120). In the recognizing of the shoes (S110), an owner of the shoes is input into data in advance, thereby the central processing unit 20 recognizes a driver.
When the shoes are recognized and the classification of the shoes is determined, the central processing unit 20 generates a signal in accordance with the information on the shoes and delivers the generated signal (S130) to the control unit 30.
After the signal is delivered from the central processing unit 20, the control unit 30 commands a control so as to set a driving environment and a driving mode in accordance with the received signal (S140). Further, the control execution unit 40 allows the operator 50 to set the driving environment and the driving mode in accordance with the command received from the control unit 30.
Once setting of the driving environment and the driving mode is completed, the driver recognition system for a vehicle is terminated (S160). Herein, the operation (S100) and the termination (S160) of the driver recognition system may be selectively performed by the driver.
Herein, setting of the driving environment means adjusting angles of an accelerator pedal and a brake pedal in accordance with information on the driver or adjusting a position of a seat, a safety belt, a mirror, or a handle. The information on the driver may be a body size of the driver. Setting of the driving mode means selecting one of modes which a user defines in advance, such as an echo mode, a sport mode, or a safety mode in accordance with classification of shoes.
The driver recognition system and method for a vehicle which take an image of shoes of the driver through the camera 10 and extract information may be extended to various technologies.
When the driver recognition system for a vehicle is associated with location based services (LBS), a guide depending on a driving purpose of the driver may be performed. For example, when hiking boots are recognized in recognizing the shoes, a guide such as recommending a hiking course, or the like may be performed.
When the driver recognition system for a vehicle is associated with a stereo, music may be played in accordance with a foot motion of a predetermined rule.
When the driver recognition system for a vehicle is designed to analyze a pedal handling habit of the driver, a correct pedal handling habit may be guided through a voice guide and display device.
The extension of the technological scope is achieved based on the driver recognition system for a vehicle which is mounted with the camera 10, signalizes and transfers information, and performs a control according to the transferred signal.
According to the exemplary embodiments of the present disclosure, as the shoes are recognized, an owner of the shoes is naturally recognized, and the driver may be accurately recognized. Accordingly, the driving environment may be set in accordance with information on the body of the driver, and safety may be secured. Further, the driving mode is selected depending on a type of the shoes to improve driver satisfaction.
While the present disclosure has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
