A supporting structure (100) for phonic wheel sensor (200) and brake caliper (300), comprises: a main body (1) fastened or which can be fastened to a stem of a fork (F) of a motorbike; a wheel support (2) connected to said main body (1) for supporting a wheel of the motorbike; and an extension (3) which develops from said main body (1) and comprises a fastening device (30) for a brake caliper (300). Two pass-through openings (31, 32) are formed in said extension (3), a first pass-through opening (31) for housing the phonic wheel sensor (200) and a second pass-through opening (32) for the passage of a cable (201) of the phonic wheel sensor (200).

A vehicle brake hydraulic pressure control apparatus includes, as a controller, acceleration acquiring section for acquiring an output value of an acceleration sensor detecting a front-rear direction acceleration of a vehicle, limiting section for limiting the magnitude of the output value acquired by the acceleration acquiring section within a predetermined limit value, a filter (control acceleration calculation section) limiting a change of a value output by the limiting section in a predetermined direction, and holding section for determining a holding pressure according to a value output by the filter and, based on the holding pressure, holding the braking force.
