PROBLEM TO BE SOLVED: To provide a motion control device of a vehicle which can prevent the overheating of an electric motor and can keep long the continuous execution time of automatic pressurization control.SOLUTION: A motion control device 50 reduces a pressure increase gradient of wheel cylinder hydraulic pressure generated through automatic pressurization control when a motor temperature T of an electric motor M reaches a referential temperature Tb or higher. Thereby, the consumption of accumulator hydraulic pressure Pa can be suppressed to reduce a driving amount (a load and driving time) of a hydraulic pump HP, namely, the electric motor M, by the suppressed amount. As a result, the overheating of the electric motor M can be prevented to improve the durability of the electric motor M. The reliability of braking can be also enhanced by keeping long the continuous execution time of automatic pressurization control. |
