Summary:PROBLEM TO BE SOLVED: To provide a brake control device capable of achieving both noise reduction and heating suppression while providing a necessary braking force. SOLUTION: This brake control device comprises a frequency control part for changing a frequency for PWM control. The frequency control part sets the PWM frequency above an audible zone at least during automatic brake control, and sets the PWM frequency lower than the present value when performing the PWM control continuously at the frequency above the audible zone and predetermined requirements are satisfied during automatic brake control.
