Claim:
1. A vehicle brake control device, comprising: operation amount acquisition means for acquiring an operation amount of a braking operation member for a vehicle by a driver; braking means including a friction member configured to be pressed by the braking means against a rotating member fixed to a wheel of the vehicle through intermediation of an electric motor to generate a braking torque for the wheel; and control means for calculating a target energization amount based on the operation amount and controlling the electric motor based on the target energization amount; wherein the control means is configured to: and wherein: the control means calculates the feedback energization amount using an incremental gradient of the feedback energization amount with respect to the increase of the correlation value deviation, said incremental gradient of the feedback energization amount with respect to the increase of the correlation value deviation being smaller than an incremental gradient corresponding to an ultimate sensitivity of a feedback control system based on the correlation value deviation, the control means calculates the first compensation energization amount using an incremental gradient of the first compensation energization amount with respect to the increase of the correlation value deviation from zero to the predetermined value, said incremental gradient of the first compensation energization amount with respect to the increase of the correlation value deviation from zero to the predetermined value being larger than the incremental gradient corresponding to the ultimate sensitivity, and the ultimate sensitivity is a predeterminerd control gain at a stability limit which is a boundary between a stable state in which vibrations of the actual correlation value are attenuated and an unstable state in which the vibrations increase.
