Abstract:
1. A brake control method for a braking device having a function of applying a brake force to a wheel equipped with a tire to put a brake on a vehicle while adjusting the brake force, the brake control method comprising the steps of: acquiring, in time series, acceleration data of acceleration applied to the tire in a radial direction of the tire; setting a predetermined detection range with respect to the acceleration data and setting a threshold value with respect to values of corresponding part of the acceleration data falling within the predetermined detection range; specifying the corresponding part of the acceleration data falling within the predetermined detection range; and controlling, when a value or values of the specified part of the acceleration data exceeds or exceed the threshold value, the brake force to be applied to the wheel as a control target, wherein, in the step of setting the predetermined detection range, when a timing at which a leading peak in the acceleration data occurs in a vicinity of a leading edge of a contact region of the tire on a ground is determined to be set as a first timing, a timing at which a trailing peak in the acceleration data occurs in a vicinity of a trailing edge of the contact region of the tire is determined to be set as a second timing, and a midway timing between the first timing and the second timing is set as a reference timing, a certain section accounting for 10 to 100% of a section defined between the first timing and the second timing with the reference timing being located in a center of the section is defined, and the defined certain section is set as the predetermined detection range.
