PROBLEM TO BE SOLVED: To provide a brake control system capable of estimating proper solenoid valve temperature without providing a sensor to detect the temperature of a solenoid valve for each of the solenoid valves and capable of restraining heating of the solenoid valve by restraining excessive electric current supply by temperature compensation. SOLUTION: Atmospheric temperature of the brake control device is estimated in accordance with input showing using circumstances of the device in a step 100, coil temperature of the solenoid valve is estimated in accordance with temperature transmitting characteristics of the solenoid valve corresponding to the estimated atmospheric temperature in a step 300, and an output duty ratio of the solenoid valve is corrected in correspondence with the estimated coil temperature in a step 400.
