摘要： A brake pressure controller for a vehicle is provided which can reliably restrain the difference between the left and right brake pressures from becoming excessively large. A controller 52 of a vehicle brake pressure controller includes an allowable differential pressure setting device 52A for setting an allowable differential pressure between the left and right wheels based on parameters indicating a motion state of a vehicle, a target control pressure setting device 52B for setting a value obtained by summing up the allowable differential pressure set by the allowable differential pressure setting device 52A and a lower-friction-side brake pressure as a target control pressure of a higher-friction-side brake pressure, and a higher-friction-side brake pressure control device 52E for adjusting the higher-friction-side brake pressure to the target control pressure.
