<p>PROBLEM TO BE SOLVED: To provide a liquid pressure control device for a vehicle brake that reduces frequencies where normal wheel speed sensors are erroneously determined to be abnormal.SOLUTION: The liquid pressure control device for a vehicle brake comprises: a first abnormality determining portion that determines whether or not one output value of at least one wheel speed sensor satisfies abnormality determination conditions (S10); a lapsed time counting portion that counts lapsed time (S20); a lapsed time selecting portion that selects a first set time during braking time when brake liquid pressure is generated in a master cylinder of the vehicle (S50) and selects a second set time shorter than the first set time during non-braking time when the brake liquid pressure is not generated in the master cylinder of the vehicle (S60); and a second abnormality determining portion that determines that abnormality occurs in the wheel speed sensor (S80) when the lapsed time counted by the lapsed time counting portion surpasses a set time selected by the lapsed time selecting portion (S70).</p> |
