<P>PROBLEM TO BE SOLVED: To provide a vehicular braking force control device capable of correctly detecting the master cylinder pressure while preventing correction from being excessive by updating the zero-point correction value so that the zero point correction value is not larger than the actual zero point deviation of a pressure sensor. <P>SOLUTION: In the vehicular braking force control device, provisional reference values Pm1p and Pm2p are set (S110), the second largest value out of the master cylinder pressure detected by pressure sensors 66 and 68, the provisional reference values, and the value smaller than the provisional reference values by a first predetermined value α is set to be the provisional reference value after the updating (S120, 160). If any braking operation is not performed by a driver, the second largest value out of the master cylinder pressure detected by the pressure sensors 66 and 68, the provisional reference value after the updating, and the value larger than the provisional reference value after the updating by a second predetermined value β is set to be the zero point correction values Pm1o and Pm2o (S150, 190), the zero point correction value is updated so as not to exceed the zero point deviation quantity of the pressure sensors 66 and 68. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
