<P>PROBLEM TO BE SOLVED: To provide a vehicular braking device capable of appropriately updating a zero-point correction value for a pressure sensor which detects pressure in a master cylinder. <P>SOLUTION: The vehicular braking device 20 includes a hydraulic pressure sensor 40 for detecting an output value corresponding to hydraulic pressure regulated by the master cylinder 23, and a master cylinder pressure calculating part 52 for storing such an output value for the hydraulic pressure sensor 40 that pressure in the master cylinder 23 is zero as the zero-point correction value, and for correcting the output value for the hydraulic pressure sensor 40, based on the zero-point correction value, to calculate the pressure in the master cylinder. The vehicular braking device includes a zero-point correction value updating part 54 for setting the output value detected by the hydraulic pressure sensor 40 when smaller than the zero-point correction value stored in the master cylinder pressure calculating part 52 as a new zero-point correction value to update the zero-point correction value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
