The method of FIG. 3 may be performed by the apparatus for detecting a size of a person outside of a vehicle 100 or may be encoded into a computer readable medium as instructions that are executable by a computer to perform the method.
Referring to FIG. 3, the size of a person approaching the vehicle is detected at the exterior of the vehicle in operation S310. Based on the detected size of the person approaching the vehicle, a position of at least one from among a vehicle control, a vehicle mirror, and a vehicle seat is adjusted in operation S320.
FIG. 4 shows a flowchart for a method of detecting a size of a person outside of a space, according to an aspect of an exemplary embodiment. The method of FIG. 4 may be performed by the apparatus for detecting a size of a person outside of a vehicle 100 or may be encoded into a computer readable medium as instructions that are executable by a computer to perform the method.
Referring to FIG. 4, the detected size of the person is a detected height. Moreover, the difference between the detected height of the person and a reference position is determined in operation 410. The difference between the detected height and the reference position is summed with the reference height of the reference position to detect the size of the person in operation S420.
FIG. 5 shows a flowchart for a method of adjusting a position based on the detected size of the person, according to an aspect of an exemplary embodiment. The method of FIG. 5 may be performed by the apparatus for detecting a size of a person outside of a vehicle 100 or may be encoded into a computer readable medium as instructions that are executable by a computer to perform the method.
Referring to FIG. 5, a preferred position of an element (e.g., a vehicle control, a vehicle mirror, a vehicle seat, etc.) is retrieved from a lookup table based on the determined size of the person in operation S510. In operation S520, a difference between the preferred position and the current position of the element is determined. If the difference between the preferred position and the current position is greater than or equal to a predetermined threshold (operation S530-YES), the position of the element is adjusted to the preferred position (operation S540). If the difference between the preferred position and the current position is less than the predetermined threshold (operation S530-NO), the position of the element is not adjusted.
The preferred position of the element may be a range of preferred element positions corresponding to the determined size of the person. The adjusted position of the element may be adjusted to the closest preferred position to the current position from among the range of preferred positions. In this regard, the lookup table may include a statistical spread of preferred positions corresponding to a detected size of a person. In this case, the element would be adjusted so as to travel the least distance to get to the closest or most favorable of the preferred positions. For example, if the range of element positions is from 0 to 10 and the preferred position is determined to be 6 with tolerance or spread of +/−5, and if the element is at position 10, the element would move until a position of 6.5 because that is within +/−5 of position 6. Moreover if the element is at position 3, the element would move to position 5.5 because that is within +/−5 of position 6. This would allow for the element to be set to the preferred position in the least amount of time.
The processes, methods, or algorithms disclosed herein can be deliverable to/implemented by a processing device, controller, or computer, which can include any existing programmable electronic control device or dedicated electronic control device. Similarly, the processes, methods, or algorithms can be stored as data and instructions executable by a controller or computer in many forms including, but not limited to, information permanently stored on non-writable storage media such as ROM devices and information alterably stored on writeable storage media such as floppy disks, magnetic tapes, CDs, RAM devices, and other magnetic and optical media. The processes, methods, or algorithms can also be implemented in a software executable object. Alternatively, the processes, methods, or algorithms can be embodied in whole or in part using suitable hardware components, such as Application Specific Integrated Circuits (ASICs), Field-Programmable Gate Arrays (FPGAs), state machines, controllers or other hardware components or devices, or a combination of hardware, software and firmware components.
