測定方法である。[Means for Solving the Problems] In view of the above-mentioned problems, the present invention is such that the load cell is always held at a regular angle and can be pressed against the surface of the pedal tread. To measure pedal force, a load meter is pressed against a footplate fixed to the other end of a pedal arm, one end of which is pivoted to a pedal bracket, to move the pedal arm up and down, and the amount of rotation of the pedal arm is measured by a position detector. In this method, a pedal force measurement method for an automatic vehicle pedal is detected in which a "stroke x load" curve is obtained from the signals emitted by the position detector and the load cell. The other end is pivoted coaxially to the support shaft of the pedal arm, and the load meter of the operating lever is attached so as to be perpendicular to the footboard, and the operating lever is rotated about the pivot point. This is a method for measuring the pedal effort of a vehicle by rotating the pedal arm via a load scale.

The back surface of the load cell 7 is fixed to the lower surface of the horizontal piece 6b of the bracket 6, and the surface of the load cell 7 is brought into contact with the surface of the footboard 1a at right angles. The operating lever 5 is provided with a handle portion 5b extending from the attachment portion of the load cell 7. Reference numeral 8 denotes a position detector whose upper end is slidably pivoted to the pedal bracket 2 via a bracket 9, and the lower end of a rod 8b is fixed to the horizontal piece 6b of the bracket 6.

正規のヒステリシス曲線が得られる。[Operation] The apparatus for implementing the method of the present invention is configured as described above, and if the handle portion 5b of the operating lever 5 is grasped by hand and the operating lever 5 is rotated downward,
The surface of the load cell 7 presses the footboard 1a of the pedal arm 1, and the pedal arm 1 rotates downward together with the operating lever 5 against the return spring 4, etc., and after reaching the end, grips the handle portion 5b. If the hand is moved upward in this state, the pedal arm 1 rotates upward and stops at the original position with the footboard 1a pressed against the surface of the load cell 7. In this case, load cell 7
is in contact with the footboard 1a at right angles, and since the centers of rotation of the pedal arm 1 and the operating lever 5 are coaxial, the angle of the load cell 7 relative to the footboard 1a varies throughout even if the pedal arm 1 rotates. Since the load cell 7 is pressed at right angles without variation, the load that the load cell 7 receives from the footboard 1a does not vary, and a regular hysteresis curve can be obtained in just one operation.

る。[Effects of the Invention] The present invention has a load meter attached to the lower end of an operating lever coaxially supported with the pedal arm in contact with the footboard at right angles, and the operating lever is rotated about the pivot point. This is a method for measuring the pedal force of an automobile pedal so as to obtain a "stroke x load" curve, and the measurement work is as simple as pushing down and returning the end of the operating lever, which reduces labor. Since the operating lever and the pedal arm have the same pivot point, the perpendicularity of the load cell to the footplate of the pedal arm does not fluctuate from beginning to end, and the measurement is performed at one point.
Accurate hysteresis curves can be obtained with only one operation. Therefore, the number of work steps is significantly reduced.
