PROBLEM TO BE SOLVED: To provide a vehicle brake system or the like which can properly determine whether or not a stoke sensor is normal.SOLUTION: When an absolute value of a difference between a detection value of a stroke sensor 41 and a prescribed reference value reaches a prescribed threshold, a control device 90 of a vehicle brake system A repeatedly performs reference value setting processing for setting the detection value at a time point when the prescribed reference value reaches the prescribed threshold as a new reference value, when the absolute value of the difference between the detection value of the stroke sensor 41 and the newest reference value reaches the prescribed threshold after performing the reference value setting process at least one time, performs normality determination processing for determining that the stroke sensor 41 is normal, and makes electrical hydraulic-pressure generation means generate hydraulic pressure to a wheel cylinder. |
