Abstract

A personal mobility device configured for preventing a plurality of occupants from riding therein and a method of controlling stability therefor, may include a sensor unit including a plurality of sensors configured to detect a current boarding weight on the personal mobility apparatus, a pressure applied to a deck, and a driving speed, a communication unit configured to transmit and receive data to or from a communication terminal device of a user, and a controller configured to analyze information on a weight of the user, provided from the communication unit, and sensing information provided from the sensor unit, to determine whether a plurality of occupants rides in the personal mobility device, and to control an operation of the driving unit, preventing an accident when a plurality of occupants rides therein.

Claims18

Dependent claims

A personal mobility apparatus comprising:

a driver configured to control a rotation of a wheel mounted in the personal mobility apparatus;
a plurality of sensors configured to detect a current boarding weight on the personal mobility apparatus and a driving speed of the personal mobility apparatus;
a wireless receiver configured to transmit and receive data to or from a mobile phone of a user;
and
a controller configured to analyze information on a weight of the user provided from a service provision server through the wireless transceiver, and sensing information provided from the plurality of sensors, to determine whether a plurality of occupants rides in the personal mobility apparatus, and to control an operation of the driver according to the determination of whether the plurality of occupants rides in the personal mobility apparatus,
wherein the controller determines whether the plurality of occupants rides the personal mobility apparatus when a result of a difference between the current boarding weight on the personal mobility apparatus and the information of the weight of the user provided from the service provision server is within an error range,
wherein the controller determines whether the plurality of occupants rides the personal mobility apparatus when the personal mobility apparatus is in a driving state, and
wherein the controller controls the driver to stop the personal mobility apparatus after driving the personal mobility apparatus at a speed lower than a reference speed for a predetermined time period when the current boarding weight on the personal mobility apparatus is greater than the weight of the user.

5 more elements

A method of controlling stability of a personal mobility apparatus, the method comprising:

receiving, by a controller, information on a weight of a user from a service provision server through a mobile phone of the user;
receiving, by the controller, sensing values from a plurality of sensors included in the personal mobility apparatus, wherein the sensing values includes a value of a current boarding weight on the personal mobility apparatus;
comparing, by the controller, the information on the weight of the user and the value of a current boarding weight on the personal mobility apparatus and determining that a plurality of occupants rides in the personal mobility apparatus when the value of the current boarding weight on the personal mobility apparatus is greater than the weight of the user provided from the service provision server;
and
upon determining that the plurality of occupants rides in the personal mobility apparatus, controlling, by the controller, an operation of a driver of the personal mobility apparatus,
wherein the controller determines whether the plurality of occupants rides the personal mobility apparatus when a result of a difference between the current boarding weight on the personal mobility apparatus and the information of the weight of the user provided from the service provision server is within an error range,
wherein the controller determines whether the plurality of occupants rides the personal mobility apparatus when the personal mobility apparatus is in a driving state, and
wherein the controller controls the driver to stop the personal mobility apparatus after driving the personal mobility apparatus at a speed lower than a reference speed for a predetermined time period when the current boarding weight on the personal mobility apparatus is greater than the weight of the user.
