The present disclosure generally relates to the field of automatic control technology, and more particularly, to a method and an apparatus for controlling a self-balancing vehicle.

An acceleration sensor and a gyroscope are provided inside the self-balancing vehicle, which may control the self-balancing vehicle according to a posture of a user's body. When it is monitored that a center of gravity of the body of the user standing on a pedal of the self-balancing vehicle moves forward, the self-balancing vehicle is controlled to speed up. When it is monitored that the body center of gravity of the user moves backward, the self-balancing vehicle is controlled to slow down.
According to a first aspect of the present disclosure, there is provided a method for controlling a self-balancing vehicle, comprising: acquiring a state of a parameter input from a user through a pedal of the self-balancing vehicle; and when the state of the parameter indicates that a change has occurred in the parameter, controlling operation of the self-balancing vehicle according to the change.
According to a second aspect of the present disclosure, there is provided an apparatus for controlling a self-balancing vehicle, comprising: a processor; and a memory for storing instructions executable by the processor, wherein the processor is configured to: acquire a state of a parameter input from a user through a pedal of the self-balancing vehicle; and when the state of the parameter indicates that a change has occurred in the parameter, control operation of the self-balancing vehicle according to the change.
According to a third aspect of the present disclosure, there is provided a non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of an apparatus, cause the apparatus to perform a method for controlling a self-balancing vehicle, the method comprising: acquiring a state of a parameter input from a user through a pedal of the self-balancing vehicle; and when the state of the parameter indicates that a change has occurred in the parameter, controlling operation of the self-balancing vehicle according to the change.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the present disclosure as recited in the appended claims.
Exemplary embodiments of the present disclosure provide methods for controlling a self-balancing vehicle. For example, the methods may be applicable in a self-balancing vehicle that has at least one pedal.
In step 101, a state of a parameter input from a user through a pedal of the self-balancing vehicle is acquired.
In the exemplary embodiment, the parameter includes at least one of: a pressure parameter, or a contact area parameter between a foot of the user and the pedal of the self-balancing vehicle. Accordingly, when the user uses the self-balancing vehicle, the user may control operation of the self-balancing vehicle through the user's foot.
In step 102, when the state of the parameter indicates that a change has occurred in the parameter, operation of the self-balancing vehicle is controlled according to the change.
In the exemplary embodiment, when the user uses the self-balancing vehicle, in order to accurately control the operation of the self-balancing vehicle, when the state of the parameter indicates that a change has occurred in the parameter, it may be further judged whether a change in a value of the parameter is larger than a threshold value. If the change in the value of the parameter is larger than the threshold value, the operation of the self-balancing vehicle is controlled according to the change.
For example, the threshold value is preset for the parameter of the self-balancing vehicle.
It should be understood that the change in the value of the parameter may be an increase in the value of the parameter, or a decrease in the value of the parameter. Generally, different changes correspond to different manners for controlling the self-balancing vehicle.
In one exemplary embodiment, when it is monitored that the value of the parameter decreases, it may be further judged whether a decrease in the value of the parameter is larger than a first threshold value. If the decrease in the value of the parameter is larger than the first threshold value, the self-balancing vehicle is controlled to slow down according to the decrease in the value.
In the present embodiment, the self-balancing vehicle may be controlled to slow down according to a magnitude of the decrease in the value of the parameter. The larger the decrease is, the larger the speed value of the self-balancing vehicle decreases.
In one exemplary embodiment, when the user uses the self-balancing vehicle having two pedals, a contact area between the user's feet and the self-balancing vehicle may be acquired. When the user uplifts a front part of each foot, it may be monitored that the contact area between the user's feet and the self-balancing vehicle decreases. At this time, it may be further judged whether a decrease in the contact area is larger than a first threshold value. If the decrease in the value is larger than the first threshold value, the self-balancing vehicle is controlled to slow down according to the decrease in the value. Thereby, the user may slow down the self-balancing vehicle by changing a state of the user's feet on the pedals of the self-balancing vehicle, which may avoid that the user loses balance due to the user's leaning backward and the backward moving of the center of gravity of the user's body. Thereby, safety of the self-balancing vehicle is improved.
In one exemplary embodiment, when it is monitored that the value of the parameter increases, it may be further judged whether an increase in the value of the parameter is larger than a second threshold value. If the increase in the value of the parameter is larger than the second threshold value, the self-balancing vehicle is controlled to speed up according to the increase in the value.
In the present embodiment, the self-balancing vehicle may be controlled to speed up according to a magnitude of the increase in the value of the parameter. The larger the increase in the value is, the larger the speed value of the self-balancing vehicle increases.
For example, when the user uses the self-balancing vehicle, a distribution of a pressure parameter on the pedal of the self-balancing vehicle may be analyzed. When it is monitored that a pressure value of the user's heel on the pedal increases, it may be further judged whether an increase in the pressure value is larger than a second threshold value. If the increase in the pressure value is larger than the second threshold value, the self-balancing vehicle is controlled to speed up according to the increase in the pressure value. Thereby, the user may conveniently control the self-balancing vehicle to speed up through the user's foot.
It should be understood that, both the first threshold value and the second threshold value are preset threshold values of the self-balancing vehicle. The first threshold value may be the same as or different from the second threshold value, which is not limited in the present disclosure.
In the method 100, during a process of controlling operation of the self-balancing vehicle, the user may control the self-balancing vehicle to speed up or slow down by changing the state of the user's feet on the self-balancing vehicle, which facilitates the user to control the self-balancing vehicle, and avoids that the user loses balance due to the user's leaning backward and the backward moving of the center of gravity of the user's body. Thereby, the safety of the self-balancing vehicle is improved.
Further, the self-balancing vehicle is controlled according to the change in the parameter input through the pedal of the self-balancing vehicle. The user may conveniently control the speed of the self-balancing vehicle by the user's foot, which increases driving safety.
In exemplary embodiments, after the operation of the self-balancing vehicle is controlled according to the change in the parameter, the method 100 may further include, when the state of the parameter indicates that the parameter is the same as that before the change occurs, controlling the self-balancing vehicle to maintain a current speed.
For example, during the user use of the self-balancing vehicle, assuming that the user puts the user's entire foot on the pedal of the self-balancing vehicle, the contact area between the user's foot and the pedal of the self-balancing vehicle acquired by the self-balancing vehicle is measured to be A at this time. In order to slow down the self-balancing vehicle, the user uplifts a front part of the user's foot. Therefore it may be determined that the contact area between the user's foot and the pedal decreases by comparison, and it is assumed that the acquired contact area is B during the process of slowing down the self-balancing vehicle. After a speed of the self-balancing vehicle reaches a desired speed, the user may put the entire foot on the pedal of the self-balancing vehicle again. At this time, the contact area between the user's foot and the pedal of the self-balancing vehicle changes from B back to A, and it may be determined that the contact area is the same as that before the change occurs. Accordingly, a current speed of the self-balancing vehicle may be acquired and the self-balancing vehicle is controlled to be operated at the current speed.
In step 201, a state of a pressure parameter input from a user through a pedal of the self-balancing vehicle is acquired.
In the exemplary embodiment, to allow the user to control operation of the self-balancing vehicle through the user's foot, a plurality of pressure sensors may be installed on the pedal of the self-balancing vehicle. When the user uses the self-balancing vehicle, pressure data collected by the plurality of pressure sensors may be analyzed, and the state of the pressure parameter may be determined according to the analysis result.
In step 202, when the state of the pressure parameter indicates that a change has occurred in the pressure parameter, a state of a contact area parameter is acquired.
In the exemplary embodiment, when the user uses the self-balancing vehicle, the state of the pressure parameter on the pedal of the self-balancing vehicle may be monitored. When the state of the pressure parameter on the pedal of the self-balancing vehicle indicates that a change has occurred in the pressure parameter, the state of the contact area parameter input from the user through the pedal of the self-balancing vehicle may be acquired.
In step 203, when the state of the contact area parameter indicates that a change has occurred in the contact area parameter, the operation of the self-balancing vehicle is controlled according to the change.
In the exemplary embodiment, after the state of the contact area parameter is acquired, it may be judged whether the state of the contact area parameter indicates that a change has occurred in the contact area parameter. When it is determined that the state of the contact area parameter indicates that a change has occurred in the contact area parameter, it may be further judged whether a change in a value of the contact area parameter is larger than a threshold value. If the change in the value of contact area parameter is larger than the threshold value, the operation of the self-balancing vehicle is controlled according to the change in the value.
For example, the threshold value is preset for the contact area parameter of the self-balancing vehicle.
In one exemplary embodiment, when the state of the contact area parameter indicates that a front part of the user's foot is uplifted, the self-balancing vehicle is controlled to slow down according to a decrease in the value of the contact area parameter.
In the present embodiment, the self-balancing vehicle may be controlled to slow down according to a magnitude of the decrease in the value of the contact area parameter. The larger the decrease is, the larger the speed value of the self-balancing vehicle decreases.
In one exemplary embodiment, when the user uses the self-balancing vehicle having two pedals, a contact area between the user's feet and the self-balancing vehicle may be acquired. When the user uplifts a front part of each foot, it may be monitored that a value of the contact area between the user's feet and the self-balancing vehicle decreases. At this time, the self-balancing vehicle may be controlled to slow down according to a decrease in the value of the contact area. Thereby, the user may slow down the self-balancing vehicle by changing a state of the user's feet on the pedals of the self-balancing vehicle, which may avoid the user losing balance due to the user's leaning backward and the backward moving of the center of gravity of the user's body. Thereby, safety of the self-balancing vehicle is improved.
In one exemplary embodiment, when the state of the contact area parameter indicates that a heel of the user is uplifted, the self-balancing vehicle is controlled to speed up according to the decrease in the value of the contact area parameter.
In the present embodiment, the self-balancing vehicle may be controlled to speed up according to a magnitude of the decrease in the value the contact area parameter. The larger the decrease in the value is, the larger the speed value of the self-balancing vehicle increases.
For example, when the user uses the self-balancing vehicle having two pedals, a contact area between the feet and the self-balancing vehicle may be acquired. When the user uplifts the user's heels, it may be monitored that the contact area between the feet and the self-balancing vehicle decreases. At this time, the self-balancing vehicle may be controlled to speed up according to the decrease in the contact area. Thereby, the user may speed up the self-balancing vehicle by changing a state of the user's feet on the pedals of the self-balancing vehicle, which may avoid the user losing balance due to the user's leaning backward and the backward moving of the center of gravity of the user's body. Thereby, safety of the self-balancing vehicle is improved.
In the method 200, during a process of controlling operation of the self-balancing vehicle, the state of the pressure parameter input from the user through the pedal of the self-balancing vehicle is acquired. When the state of the pressure parameter indicates that a change has occurred in the pressure parameter, the state of the contact area parameter is acquired. When the state of the contact area parameter indicates that a change has occurred in the contact area parameter, the self-balancing vehicle is controlled according to the change. Therefore, the user may control the operation of the self-balancing vehicle by changing the state of the user's feet on the self-balancing vehicle, which facilitates the user to control the self-balancing vehicle, and avoids that the user loses balance due to the user's leaning backward and the backward moving of the center of gravity of the user's body. Thereby, safety of the self-balancing vehicle is improved.
In step 301, a state of a contact area parameter input from a user through a pedal of the self-balancing vehicle is acquired.
In the exemplary embodiment, when the user uses the self-balancing vehicle, contact area data of the user's foot on the pedal may be acquired by a touch sensor on the pedal. The acquired contact area data may be analyzed through the touch sensor, and the state of the contact area parameter input from the user through the pedal of the self-balancing vehicle is determined according to the analysis result.
In step 302, when the state of the contact area parameter indicates that a change has occurred in the contact area parameter, a state of a pressure parameter is acquired.
In the exemplary embodiment, when the user uses the self-balancing vehicle, the state of the contact area parameter may be monitored. When it is monitored that a change has occurred in the state of the contact area parameter, it may be determined that a value of the contact area parameter changes. In order to accurately control the operation of the self-balancing vehicle, the state of the pressure parameter input from the user through the pedal of the self-balancing vehicle is further acquired.
In step 303, when the state of the pressure parameter indicates that a change has occurred in the pressure parameter, operation of the self-balancing vehicle is controlled according to the change.
In the exemplary embodiment, after the state of the pressure parameter is acquired, it may be judged whether the state of the pressure parameter indicates that a change has occurred in the pressure parameter. When it is determined that the state of the pressure parameter indicates that a change has occurred in the pressure parameter, it may be further judged whether a change in the value of the pressure parameter is larger than a threshold value. If the change in the value of the pressure parameter is larger than the threshold value, the operation of the self-balancing vehicle is controlled according to the change.
For example, the threshold value is preset for the pressure parameter of the self-balancing vehicle.
In one exemplary embodiment, when the state of the pressure parameter indicates that a change has occurred in the pressure parameter, a change in a value of the pressure parameter at a front part of the user's foot, input through the pedal of the self-balancing vehicle, may be further acquired. If it is determined that the value of the pressure parameter at the front part of the user's foot decreases, it may be further judged whether a decreases in the value of the pressure parameter is larger than a threshold value. If the decrease in the value of the pressure parameter is larger than the threshold value, the self-balancing vehicle is controlled to slow down according to the decrease in the value.
In the present embodiment, the self-balancing vehicle may be controlled to slow down according to a magnitude of the decrease in the value of the pressure parameter. The larger the decrease in the value is, the larger the speed value of the self-balancing vehicle decreases.
In one exemplary embodiment, if it is determined that the value of the pressure parameter at the front part of the user's foot increases, it may be further judged whether an increase in the value of the pressure parameter is larger than a threshold value. If the increase in the value of the pressure parameter is larger than the threshold value, the self-balancing vehicle is controlled to speed up according to the increase in the value.
In the present embodiment, the self-balancing vehicle may be controlled to speed up according to a magnitude of the increase in the value of the pressure parameter. The larger the increase in the value is, the larger the speed value of the self-balancing vehicle increases.
For example, to determine that the value of the pressure parameter at the front part of the user's foot increases, the self-balancing vehicle may analyze a distribution of the pressure parameter on the pedal of the self-balancing vehicle.
It should be understood that, the threshold values for different parameters may be preset for the self-balancing vehicle. A threshold value may be the same as or different from another threshold value, which is not limited in the present disclosure.
In the method 300, during a process of controlling operation of the self-balancing vehicle, the state of the contact area parameter input from the user through the pedal of the self-balancing vehicle is acquired. When the state of the contact area parameter indicates that a change has occurred in the contact area parameter, the state of the pressure parameter is acquired. When the state of the pressure parameter indicates that a change has occurred in the pressure parameter, the self-balancing vehicle is controlled according to the change in the value. Therefore, the user may control the operation of the self-balancing vehicle by changing a state of the user's feet on the self-balancing vehicle, which facilitates the user to control the self-balancing vehicle, and avoids that the user loses balance due to the user's leaning backward and the backward moving of the center of gravity of the user's body. Thereby, safety of the self-balancing vehicle is improved.
