[0044] The handle shaft (11) is connected approximately vertically to the footrest (12), and a handle bar (13R, 13L) and a control unit (300) may be provided at the top of the handle shaft (11). As the driver operates the handle bar (13R, 13L), the handle shaft (11) performs steering of the front wheel (14). The footrest (12) provides a support surface on which the driver sits. A battery (130) may be provided on one side of the handle shaft (11) or on one side of the footrest (12). The wheels (14, 15) include a front wheel (14) and a rear wheel (15). The front wheel (14) may be provided at one end of the handle shaft (11) in front of the footrest (12), and the rear wheel (15) may be provided at the rear of the footrest (12).

[0045] The motor (20) is connected to the front wheel (14), and the front wheel (14) can rotate by driving the motor (20). The drive shaft of the motor (20) can be arranged to coincide with the wheel frame and rotation axis of the front wheel (14). Meanwhile, the position where the motor (20) is provided can vary. The motor (20) can be provided to rotate the rear wheel (15), or it can be provided to rotate both the front wheel (14) and the rear wheel (15). The motor (200) can be a standard BLDC (Brushless Direct Current Motor) or a drive and regenerative braking type motor (e.g., combined motor and generator).

[0046] The braking device (30) can apply braking force to the wheels (14, 15). The braking device (30) can be operated by the operation of the brake lever (50R, 50L) or by the control of the control unit (300).

The radar (110) may acquire radar data from the transmitted radio waves transmitted by the transmitting antenna and the reflected radio waves received by the receiving antenna. The radar data may include distance information and speed values ​​regarding objects around the personal mobility (1). The radar (110) may calculate the relative distance to an object based on the phase difference (or time difference) between the transmitted radio waves and the reflected radio waves, and calculate the relative speed of an object based on the frequency difference between the transmitted radio waves and the reflected radio waves.

[0049] The radar (110) is electrically connected to the control unit (300) and can transmit radar data to the control unit (300). Meanwhile, the radar (110) described above may be implemented as a lidar.

[0050] A pressure sensor (120R, 120L) is installed on the handlebar (13R, 13L) and can measure the pressure applied to the handlebar (13R, 13L) and obtain a pressure value. The pressure sensor (120R, 120L) can be installed on the right handlebar (13R) and the left handlebar (13L), respectively. When a driver is riding the personal mobility (1), the driver must hold the handlebar (13R, 13L). For example, when the driver holds the handlebar (13R, 13L) with their hand, there is pressure transmitted from the driver's hand to the handlebar (13R, 13L). The pressure sensor (120R, 120L) can measure the pressure applied to the handlebar (13R, 13L) by the driver and obtain a pressure value.

[0051] The front light (210) is installed in front of the handle shaft (11) and can emit light toward the front of the personal mobility (1). The rear light (220) is installed on the rear wheel cover (16) and can emit light toward the rear of the personal mobility (1). The front light (210) and the rear light (220) may be implemented with LEDs, but are not limited thereto. The front light (210) and the rear light (220) may be powered by a battery (130) or may include a separate battery.

[0052] A haptic device (230R, 230L) is installed on a handlebar (13R, 13L) and can generate vibrations on the handlebar (13R, 13L). The haptic device (230R, 230L) may be provided together with or separately from a pressure sensor (120R, 120L). At least one of a handlebar gripping warning or a collision risk warning may be provided to the driver by the vibration of the haptic device (230R, 230L).

[0053] An audio device (240) may be provided in a control unit (300) and may output a warning sound. The audio device (240) may include a speaker. The warning sound may be, for example, a sound of 70 dB or higher. At least one of a handlebar gripping warning or a collision risk warning may be provided to the driver by the warning sound output from the audio device (240).

[0054] Although not illustrated in FIGS. 1 and 2, the personal mobility (1) may include a display (250). The display (250) may be provided in the control unit (300) and may display various information related to the operation of the personal mobility (1). The display (250) may display a user interface. The user interface may be a graphic user interface (GUI). The display (250) may be implemented as a light-emitting diode (LED) panel, an organic light-emitting diode (OLED) panel, or a liquid crystal display panel. The display (250) may also include a touch panel.

[0055] The control unit (300) is electrically connected to the motor (20), braking device (30), radar (110), pressure sensor (120), battery (130), front light (210), rear light (220), haptic device (230), audio device (240), and display (250), and can control each of them. The control unit (300) can be implemented in the form of a control box provided at the top of the handle shaft (11) and may include a control circuit.

[0056] The operation of a personal mobility device according to one embodiment will be described in detail below.

[0057] FIG. 3 is a control block diagram of a personal mobility device according to one embodiment.

[0058] Referring to FIG. 3, the personal mobility (1) may include, as described above, a motor (20), a braking device (30), a radar (110), a pressure sensor (120), a battery (130), a front light (210), a rear light (220), a haptic device (230), an audio device (240), a display (250), and a control unit (300). Additionally, the personal mobility (1) may include a communication unit (140) and an input unit (150), and may include a plurality of sensors such as a speed sensor (160), a gyroscope sensor (170), a position sensor (180), and a lock sensor (190). The control unit (300) is electrically connected to each component of the personal mobility (1) and can control each of them.

[0059] The communication unit (140) can perform communication between the personal mobility (1) and an external device. As illustrated in FIG. 3, the personal mobility (1) can communicate with the server (2), communicate with the user terminal (3), and communicate with the helmet (4). In other words, the personal mobility (1) can be connected to external devices such as the server (2), the user terminal (3), and the helmet (4) through a network.

[0060] Meanwhile, the helmet (4) includes a communication device and a sensor that detects whether the helmet is being worn. When the helmet (4) is worn by a user, it can transmit a helmet wearing signal to the control unit (300) through the communication unit (140) of the personal mobility (1).

[0061] The communication unit (140) may be a communication circuit to which various communication technologies are applied. For example, the communication unit (140) may communicate with external devices using wireless communication and / or wired communication. Wireless communication may include communication technologies such as 5G (5th Generation), LTE, LTE-A (LTE Advance), CDMA (Code Division Multiple Access), WCDMA (Wideband CDMA), UMTS (Universal Mobile Telecommunications System), WiBro (wireless broadband), or GSM (Global System for Mobile communications). Wired communication may include USB (Universal Serial Bus) communication, HDMI (High Definition Multimedia Interface) communication, RS-232 (Recommended Standard-232) communication, power line communication, or POTS (Plain Old Telephone Service) communication. The network may include a telecommunication network, a computer network (e.g., LAN or WAN), the Internet, or a telephone network.

[0062] The user terminal (3) may be implemented as a portable terminal or a fixed terminal. A portable terminal is an electronic device that is easy to carry and move, and may include a video phone, a mobile phone, a smartphone, a WCDMA (Wideband Code Division Multiple Access) terminal device, a UMTS (Universal Mobile Telecommunication Service) terminal device, a PDA (Personal Digital Assistant), a PMP (Portable Multimedia Player), a DMB (Digital Multimedia Broadcasting) terminal device, an E-Book, a portable computer (Notebook, Tablet, etc.), or a digital camera. A fixed terminal is an electronic device that can be fixed and used at a specific location, and may include a desktop personal computer, a smart TV, etc.

[0063] The input unit (150) can receive input from a user and / or driver. For example, the input unit (150) may be an input device such as a touch pad or a touch panel. The input unit (150) may be implemented as a display (250) including a touch panel. The control unit (300) can process commands input through the input unit (150) and execute functions of the personal mobility (1) corresponding thereto. The display (250) including the touch panel can convert the user's touch input into an electrical signal and transmit it to the control unit (300). The control unit (300) can process the electrical signal based on the user's touch input and execute functions of the personal mobility (1) corresponding thereto.

[0064] Personal mobility (1) may include various sensors. The sensors may collect driving behavior data. For example, personal mobility (1) may include at least one of a speed sensor (160) for measuring speed, a pressure sensor (120) for measuring pressure applied to the handlebars, a gyroscope sensor (170) for measuring tilt, a position sensor (180) for acquiring geopolitical location information, and a lock sensor (190) for detecting whether it is locked. Personal mobility (1) may also include other sensors in addition to the sensors described above.

[0065] The control unit (300) can calculate the average speed based on the speed value obtained from the speed sensor (160). Additionally, the control unit (300) can determine rapid acceleration and rapid deceleration based on the speed value obtained from the speed sensor (160). The control unit (300) can count the number of rapid accelerations and rapid decelerations. The control unit (300) can determine whether two-hand driving is performed based on the pressure value obtained by the pressure sensor (120). The control unit (300) can check the current location, driving path, driving road type, and / or return location based on the location information obtained by the location sensor (180).

[0066] The control unit (300) can estimate the posture of the personal mobility (1) based on the tilt value obtained by the gyro sensor (170) and can determine the parking state based on the estimated posture. The parking state can be classified into normal parking and incomplete parking. The control unit (300) can determine incomplete parking if the personal mobility (1) is not standing upright. Additionally, the control unit (300) can determine the parking state based on the lock status confirmed by the lock sensor (190). The control unit (300) can determine incomplete parking if the lock is not confirmed even after parking.

[0067] The control unit (300) can determine whether the front light (210) and the rear light (220) are each lit based on a signal transmitted from a lighting sensor included in each of the front light (210) and the rear light (220).

[0068] The control unit (300) may include a memory (320) storing a program and / or application for operating personal mobility and a processor (310) for executing the stored program and / or application. The memory (320) and the processor (310) may be integrated on a single chip. Additionally, the memory (320) and the processor (310) may be provided in physically separate locations. Additionally, the memory (320) and the processor (310) may each be provided in multiple units.

[0069] The processor (310) processes radar data of the radar (110) and sensor data obtained by a plurality of sensors, generates a motor driving signal and a braking signal, and can generate operation signals for the front light (210), rear light (220), haptic device (230), audio device (240) and display (250).

[0070] The memory (320) can store at least one instruction for the processor (310) to obtain driver's grade information from the server (2), determine the maximum speed and maximum torque of the motor (20) based on the driver's grade information, update the driver's grade information based on driving behavior data collected during driving, and control the display (250) to display the driver's grade information.

[0071] The memory (320) may be implemented as at least one of a non-volatile memory device such as a cache, ROM (Read Only Memory), PROM (Programmable ROM), EPROM (Erasable Programmable ROM), EEPROM (Electrically Erasable Programmable ROM) and flash memory, a volatile memory device such as RAM (Random Access Memory), or a storage medium such as a hard disk drive (HDD) and CD-ROM to store various information, but is not limited thereto.

[0072] The control unit (300) can obtain driver grade information from the server (2), determine the maximum speed and the maximum torque of the motor (20) based on the driver grade information, update the driver grade information based on driving behavior data collected by sensors during driving, and control the display (250) to display the driver grade information.

[0073] Specifically, the control unit (300) can extract driving factors from driving behavior data, calculate a score for each driving factor, and determine driver grade information based on a total score obtained by summing the scores for the driving factors. The driving factors may include average speed, number of sudden accelerations, number of sudden decelerations, whether a helmet is worn, whether two-handed driving is performed, type of road, whether lights are turned on at night, return location, and parking status.

[0074] Driver grade information can be set in various ways. For example, a driver's grade can be divided into five grades based on score: top grade, high grade, middle grade, low grade, and lowest grade. The top grade may correspond to 81 to 100 points, the high grade to 61 to 80 points, the middle grade to 41 to 60 points, the low grade to 21 to 40 points, and the lowest grade to 0 to 20 points.

[0075] The driver's grade can be determined based on driving behavior data included in past driving records. However, if driving behavior data from the entire accumulated driving record is reflected, it may be difficult to upgrade the driver's grade. Therefore, the control unit (300) may determine the driver's grade by reflecting only the driving behavior data included in the driving records and / or the number of driving events during a predetermined period. For example, in determining the driver's grade, only the last 5 driving records may be used, and driving records from 3 months prior may not be used. Additionally, the driver's grade may be determined by giving 70% weight to the average score based on the last 5 driving records and 30% weight to the average score based on the driving records from the previous 3 months.

[0076] Meanwhile, although it was explained that the control unit (300) of the personal mobility (1) calculates the driver's grade, the driver's grade may also be calculated by the server (2).

[0077] The control unit (300) can control the display (250) to display penalty guidance information while driving. The penalty guidance information may include driving factors that affect the current driver's rating and guide messages that help prevent the score of said driving factors from decreasing. Additionally, the penalty guidance information may include navigation information. The control unit (300) can generate penalty guidance information based on the current driver's rating information and driving behavior data acquired while driving.

[0078] The control unit (300) can control the display (250) to selectively display penalty guidance information based on the driver's input. The driver can select whether to display penalty guidance information through the input unit (150). Additionally, the driver can select whether to display penalty guidance information using the user terminal (30).

[0079] Meanwhile, the control unit (300) can determine the maximum speed and maximum torque to smaller values ​​as the driver's grade decreases. For example, the maximum speed of the device itself may be 25 km / h and the maximum torque may be 25 N·m. If the driver's grade is the highest grade, the control unit (300) can determine the maximum speed to 25 km / h and the maximum torque to 25 N·m. However, if the driver's grade is the lowest grade, the control unit (300) can determine the maximum speed to 10 km / h and the maximum torque to 10 N·m. The control unit (300) controls the personal mobility (1) so that the driver cannot increase the speed beyond the determined maximum speed and maximum torque. A low driver grade means a low level of proficiency. In other words, the accident rate can be reduced by making the vehicle operate at a lower speed as the driver's grade decreases.

[0080] Additionally, the control unit (300) can control the display (250) to display safety training completion information when the driver's grade is the lowest grade. The control unit (300) can upgrade the driver's grade when the safety driving training is completed. For example, the control unit (300) can upgrade the driver's grade by one level to a lower grade. Additionally, the control unit (300) can restrict the operation of the personal mobility (1) until the safety training is completed when the driver's grade is the lowest grade. That is, a driver with the lowest grade can operate the personal mobility (1) after completing the safety training.

[0081] The control unit (300) can control the display (250) to calculate the usage fee based on the driver's grade information updated after the driving is completed, and to display the usage fee and grade upgrade guide information. The control unit (300) can calculate the usage fee by reflecting a fee discount reward when the driver's grade is the highest grade. Grade upgrade guide information refers to information that guides how to upgrade from the current driver's grade to the next grade. For example, if the current driver's grade is the upper grade and has 78 points, it can become the highest grade by raising it by 3 more points. Therefore, a method to raise it by 3 more points can be provided.

[0082] Figure 4 is a table explaining the driving factor and driver rating calculation method.

[0083] As described above, the control unit (300) can extract driving factors from driving behavior data, calculate a score for each driving factor, and determine the driver's grade information based on the total score obtained by summing the scores for the driving factors.

[0084] Referring to the table (400) in FIG. 4, driving factors may include average speed, number of rapid accelerations, number of rapid decelerations, whether a helmet is worn, whether two-hand driving is performed, type of road, whether the front light is on, whether the rear light is on, return location, and parking status. The maximum score for each driving factor may be 10 points, and the maximum total score may be 100 points.

[0085] The control unit (300) can deduct points for the average speed when the average speed exceeds a predetermined speed, i.e., when it is overspeeding. The control unit (300) can deduct points based on the number of rapid accelerations and can deduct points based on the number of rapid decelerations. Rapid acceleration refers to a case where the instantaneous acceleration exceeds a predetermined acceleration.
