When the turn signal activation sensor (110) is implemented as a voice recognition sensor (111), the voice recognition sensor (111) obtains a voice from a user, and the activation data may be voice activation data. The control unit (130) obtains and analyzes the voice activation data from the voice recognition sensor (111), and when it is determined that the voice activation data includes a predefined activation command, it can control the turn signal to operate. For example, when it is determined that a predefined first activation command is included, the left turn signal operates, when it is determined that a predefined second activation command is included, the right turn signal operates, and when it is determined that a predefined third activation command is included, it can control the left and right turn signal lights to operate in an emergency light mode in which both operate.

The control unit (130) obtains and analyzes the motion activation data from the motion detection sensor (112), and when it is determined that the motion activation data includes a predefined activation command, it may control the turn signal to operate. For example, when it is determined that a predefined first activation command is included, the left turn signal operates, when it is determined that a predefined second activation command is included, the right turn signal operates, and when it is determined that a predefined third activation command is included, it may control the left and right turn signal lights to operate in an emergency light mode in which both operate.

When the turn signal activation sensor (110) is implemented as a touch sensor (113), the touch sensor (113) obtains touch information (e.g., one touch, two consecutive touches, continuous touch, etc.) from the user, and the activation data may be touch activation data. The control unit (130) obtains and analyzes the touch activation data from the touch sensor (113), and when it is determined that the touch activation data includes a predefined activation command, it can control the turn signal to operate. For example, when it is determined that a predefined first activation command is included, the left turn signal operates, when it is determined that a predefined second activation command is included, the right turn signal operates, and when it is determined that a predefined third activation command is included, it can control the left and right turn signal lights to operate in an emergency light mode in which both operate.

When the obstacle recognition sensor (120) is implemented as a camera sensor (121), the obstacle recognition sensor generates image data of the front and side, and the control unit (130) can determine the presence or absence of obstacles around the shared mobility based on the image data and determine whether or not to output an obstacle recognition notification based on the image data.

When the obstacle recognition sensor (120) is implemented as a proximity sensor (122), the obstacle recognition sensor generates infrared data of the front and side, and the control unit (130) can determine the presence of obstacles around the shared mobility based on the infrared data and, based on this, determine whether to output an obstacle recognition notification.

The control unit (130) can receive commands from other components of the control device (100) through the data bus (160), interpret the received commands, and execute operations or data processing according to the interpreted commands.

According to one embodiment, at step S5000, the control unit (130) may obtain and analyze activation data and obstacle recognition data, and determine whether to activate the turn signal and whether to output an obstacle recognition notification.

The memory unit (140) may store commands or data received from the control unit (130) or other components of the control device (100) or generated by the control unit (130) or other components. According to some embodiments, the memory unit (140) may be composed of a program memory and a data memory, and the program memory stores a program for controlling general operations of the mobile terminal. According to some embodiments, the memory unit (140) may further include an external memory such as a Compact Flash (CF), a Secure Digital (SD), a Micro-SD (Micro Secure Digital), a Mini-SD (Mini Secure Digital), an xD (Extreme Digital), and a Memory Stick. In addition, the memory unit (140) may include a disk storage device such as a Hard Disk Drive (HDD) and a Solid State Disk (SSD).

The interface unit (150) can connect communication between the control device (100) and another device (for example, a control device of another mobility) or a server (not shown). The interface unit (150) can support a predetermined short-range communication protocol (for example, Wi-Fi (wireless fidelity), BT (Bluetooth), NFC (near field communication), a predetermined network communication (for example, Internet, LAN (local area network), WAN (wire area network), telecommunication network, cellular network, satellite network, or POTS (plain old telephone service)), or a wired communication protocol (for example, USB (universal serial bus), HDMI (high definition multimedia interface), etc.).
