PROBLEM TO BE SOLVED: To provide a traveling control device of a vehicle which properly suppresses ABS control in the case other than an emergency even if the ABS control is performed due to a change of a road face status during automatic drive, and does not impart incongruity to a driver.SOLUTION: When it can be determined that the safety of a vehicle is secured when ABS is operated by a change of a road face state to, for example, a low-μ road face and an uneven-μ road face from a high-μ road face, a traveling control device of a vehicle suppresses an operation of ABS control by changing brake fluid pressure Pb to brake fluid pressure which is lower than brake fluid pressure at which a tire is locked by a prescribed amount, and holding it.SELECTED DRAWING: Figure 2 |
