A vehicle motion control device which detects an abnormality of an automatic hydraulic pressure generator having a master cylinder, a booster which boosts the master cylinder and a booster actuator which actuates the booster irrespective of brake pedal operation and performs an appropriate transaction upon detecting the abnormality. The vehicle motion control device includes the automatic hydraulic pressure generator, a hydraulic pressure control valve disposed between the automatic hydraulic pressure generator and a wheel cylinder, and a controller performing the automatic pressure increase control by actuating the hydraulic pressure control valve and the booster actuator according to the vehicle running condition. By calculating a master cylinder hydraulic pressure based on a variable state of the booster actuator and comparing the calculated value with the master cylinder hydraulic pressure detected by a hydraulic pressure sensor, an abnormality of the automatic hydraulic pressure generator is detected during non-operation of the brake pedal.
