The invention discloses an automobile switch operating force testing method, which comprises the following steps of: (1) pressing a key, monitoring force and
stroke data in real time, recording, storing and generating a data sequence when the operating force is greater than or equal to a preset minimum force Fmin, and stopping when the operating force exceeds a threshold value or is pressed in place; (2) traversing the force data sequence, identifying extreme points and storing the extreme points into an array,
processing adjacent extreme points of the same type, and calculating a force peak-valley difference value; (3) traversing the array set, calculating a force peak valley difference value of adjacent different types of extreme points, comparing the difference value with a preset threshold value, and screening an effective difference value to form an array; (4) sorting the difference value array, if the difference value is invalid, judging that the curve is invalid, and if the difference value is invalid, judging that the curve is invalid, otherwise, judging that the curve is invalid. If yes, storing the peak-valley extreme
point data into a two-dimensional array, and forming a force-
stroke relation array in combination with the
stroke data; according to the method, through multi-condition filtering and peak valley detection, automatic and accurate testing of the automobile switch operating force is achieved, and the problems that an existing method is poor in
interference resistance and prone to misjudgment are solved.
