A control method and system for adjusting the relative position of a mobile household with respect to a human is provided by the present disclosure. The mobile household device obtains the location information of the target object at multiple time points, and, according to the obtained location information, determines the current moving direction and positional relation of the target object relative to the mobile household device, and moves to the dominant hand side of the target object according to preset conditions. By detecting and analyze the state of the user, the mobile household device can actively adjust its motion, thus improving its intelligence level.

1. A control method for adjusting a relative position of a mobile household device with respect to a human, comprising the following steps: locating by the mobile household device and obtaining location information of a target object at multiple time points, wherein the mobile household device is enabled with at least one of indoor and/or outdoor positioning capabilities, the outdoor positioning capabilities are realized by global positioning system (GPS), and the indoor positioning capabilities are achieved via wireless fidelity (WIFI) positioning, Bluetooth positioning and radiation sensing positioning; wherein locating by the mobile household device comprises: choosing the mobile household device itself as an origin, orientation of front side of the mobile household device pointing front as a positive half of Y axis to establish a rectangular coordinate system, the front side of the mobile household device being the side facing right ahead when the mobile household device is moving in accordance with a planned path; obtaining the location information of the target object at the multiple time points comprises: locating the target object and utilizing the established rectangular coordinate system to obtain position coordinates of the target object at two subsequent time points; wherein the step of utilizing the established rectangular coordinate system to obtain the position coordinates of the target object at the two subsequent time points, comprises: locating and obtaining the position coordinates of the target object at the subsequent time point in the rectangular coordinate system where the position coordinates of the target object at the previous time point are obtained;according to the obtained location information of the target object at the multiple time points, determining a current moving direction and a positional relation of the target object relative to the mobile household device; andaccording to the resultant moving direction and positional relation of the target object relative to the mobile household device, moving by the mobile household device to a dominant hand side of the target object in accordance with preset handedness rules; wherein:the step of according to the obtained location information of the target object at the multiple time points, determining the current moving direction and positional relation of the target object relative to the mobile household device, comprises: according to the obtained position coordinates of the target object at the two subsequent time points, determining whether the target object is moving towards or away from the mobile household device; wherein the step of according to the obtained position coordinates of the target object at the two subsequent time points, determining whether the target object is currently moving towards or away from the mobile household device, comprises: when (Xa×Xa+Ya×Ya)(Xb×Xb+Yb×Yb), the target object is determined to be moving towards the mobile household device; andfurther utilizing the position coordinates of the target object at the two subsequent time points to determine the relative positional relation between the mobile household device and the target object. 2. The control method for adjusting the relative position of the mobile household device with respect to the human according to claim 1, wherein, the obtained location information of the target object at the multiple time points comprises a relative position of the target object with respect to the mobile household device or an absolute position of the target object with respect to a stationary reference object. 3. The control method for adjusting the relative position of the mobile household with respect to the human according to claim 1, wherein the step of further utilizing the position coordinates of the target object at the two subsequent time points to determine the positional relation between the mobile household device and the target object, comprising: when the target object is determined to be moving away from the mobile household device, further judging rules for determining the positional relation are: when Ya/Xa=Yb/Xb, the mobile household device is determined to be positioned directly behind the target object;when Ya/Xa>Yb/Xb, the mobile household device is determined to be positioned behind the right side of the target object;when Ya/XaYb/Xb, the mobile household device is determined to be located in front of the right side of the target object;when Ya/Xa(Xb×Xb+Yb×Yb), the target object is determined to be moving towards the mobile household device; andfurther utilizing the position coordinates of the target object at the two subsequent time points to determine the relative positional relation between the mobile household device and the target object. 7. The control method for adjusting the relative position of the mobile household with respect to the human according to claim 6, wherein the step of further utilizing the position coordinates of the target object at the two subsequent time points to determine the positional relation between the mobile household device and the target object, comprising: when the target object is determined to be moving away from the mobile household device, further judging rules of determining the positional relation are: when Ya/Xa=Yb/Xb, the mobile household device is determined to be located directly behind the target object;when Ya/Xa>Yb/Xb, the mobile household device is determined to be located behind the right side of the target object;when Ya/XaYb/Xb, the mobile household device is determined to be located in front of the right side of the target object;when Ya/Xa(Xb×Xb+Yb×Yb), the target object is determined to be moving towards the mobile household device; andfurther utilize the position coordinates of the target object at the two subsequent time points to determine the relative positional relation between the mobile household device and the target object.
