Referring to fig. 2, a flowchart of a method for testing a foot-operated control device according to an embodiment of the present application is shown, the method being used in the apparatus shown in fig. 1, and as shown in fig. 2, the method includes:
in the pedal dimension experiment, a subject is required to judge the dimension of the pedal in a subjective evaluation mode, wherein the dimension of the pedal in the width direction and the dimension of the pedal in the length direction are included, so that the reasonable range of the geometric dimension of the pedal is known.
In the pedal geometry experiment, the subject subjectively evaluated the pedal size according to the feeling of operating the pedal with the foot without knowing the pedal size. During the test, the subject must be prevented from seeing the pedal, so as to ensure the normal subjective evaluation of the subject.
The width of the pedal is not changed during the experiment of the length dimension of the pedal, so that the judgment of a subject on the length dimension is not influenced. And in practical implementation, at least two foot-operated control devices with different lengths of the width are arranged on the pedal bracket of the device for each width in the candidate widths, and the test result of the test subject on each foot-operated control device is obtained, wherein the candidate widths comprise at least two. That is, the foot-operated control device with at least two widths and different lengths can be tested. For example, the length dimension experiment of the pedal is divided into 3 groups, the widths are respectively 80mm, 60mm and 40mm, the length range of each group is 40 mm-140 mm, and the length dimensions in the experiment in the group are randomly sequenced.
In practical implementation, the specific experimental steps are as follows:
a subject sits on the seat, the right foot is placed on the pedal, the heel touches the ground, the front evaluation meter is looked up, and the subject cannot lower the head in the whole experiment process (the judgment is not influenced by the size of the pedal);
adjusting the height and fore-and-aft position of the seat to bring the subject into a comfortable foot-operated position and the inclination of the foot board to 52 °;
first, a dimension experiment in the width direction of the footrest was performed. Taking a pedal with the length of 40mm for experiment, namely 6 pedals of 40mm multiplied by 40mm, 40mm multiplied by 60mm, 40mm multiplied by 80mm, 40mm multiplied by 100mm, 40mm multiplied by 120mm and 40mm multiplied by 140mm, putting the pedal on a pedal bracket, giving the evaluation value of the width of the pedal according to subjective feeling by a subject, and recording the evaluation value; the placement sequence of 6 pedals is randomly arranged;
taking a pedal with the length of 60mm for an experiment, namely 6 pedals of 60mm multiplied by 40mm, 60mm multiplied by 60mm, 60mm multiplied by 80mm, 60mm multiplied by 100mm, 60mm multiplied by 120mm and 60mm multiplied by 140mm, putting the pedals on a pedal bracket, giving the width value of the pedals according to subjective feeling by a subject, and recording the value of the pedal; the 6 foot pedals are randomly arranged in sequence;
taking a foot pedal with the length of 80mm for an experiment, namely, 6 foot pedals of 80mm multiplied by 40mm, 80mm multiplied by 60mm, 80mm multiplied by 80mm, 80mm multiplied by 100mm, 80mm multiplied by 120mm and 80mm multiplied by 140mm are put on a pedal bracket, and a subject gives the width value of the foot pedal according to subjective feeling and records the value of the foot pedal; the 6 pedals are randomly arranged in the placement sequence;
at this point, a first test result may be obtained.
the length of the pedal is not changed in the experiment of the width dimension of the pedal, so that the judgment of a subject on the width dimension is not influenced. The width dimension experiment of the pedal is divided into 3 groups, the lengths are respectively 80mm, 60mm and 40mm, the width range of each group is 40 mm-140 mm, and the width dimensions in the group experiment are randomly sorted.
In practice, for each of the candidate lengths, at least two foot-operated control devices with different widths of the length are mounted on the pedal bracket of the device, and the test result of the subject on each foot-operated control device is obtained, wherein the candidate lengths comprise at least two.
Similar to step 201, the method first takes 6 pedals with a width of 40mm for test scoring, then takes 6 pedals with a width of 60mm for test scoring, and finally takes 6 pedals with a width of 80mm for test scoring of the size of the dimension in the length direction, so as to obtain a second test result, which is not limited in this embodiment.
After the first test result and the second test result are obtained, the width and the length of the pedal which are the best experienced by the testee can be selected, and then the optimal foot-operated control device is obtained.
Optionally, in the actual use process, the setting angle of the pedal may affect the use experience of the user, for example, for the automobile brake, if the setting angle is too large, the user experience is poor, and if the setting angle is too small, the brake force cannot be completely controlled, because the method may further include the following steps in order to improve the use experience of the designed foot-operated control device:
(1) acquiring a third test result of the subject on the foot-operated control device with at least two inclination angles;
the inclination angle of the pedal is an acute angle between the pedal and the horizontal plane. The pedal inclination angle experiment adopts a subjective evaluation mode, different inclination angles of the pedal are set, and a subject can make subjective evaluation on the inclination angle of the pedal according to the comfort level of the pedal operated by the foot under the condition that the size of the pedal is unknown.
The specific experimental steps are as follows:
when a person sits on the seat in a test mode, the right foot is placed on the pedal, the heel of the foot is grounded, and the front evaluation table is looked up;
the height and the front and back positions of the seat are adjusted to ensure that the tested posture is in a comfortable state;
the inclination angle (any one of 13 degrees, 26 degrees, 39 degrees, 52 degrees and 78 degrees) of the pedal plate is adjusted, the subject gives scores according to subjective feelings, and the evaluation result can be recorded by adopting a recording mode shown in the table 1.
(2) And determining the recommended inclination angle of the foot-operated control device according to the third test result.
For example, if the subject evaluates best to 52 °, 52 ° is set as the recommended tilt angle.
In summary, at least two foot-operated control devices with the same width and different lengths are mounted on a pedal bracket of the equipment, and a first test result of a subject on each foot-operated control device is obtained; mounting at least two foot-operated control devices with different widths and the same length on a pedal bracket of the equipment, and acquiring a second test result of the test subject on each foot-operated control device; and selecting a foot-operated control device with a target size according to the first test result and the second test result.
