Patent ID: 8583337

Claim:
A brake device for a vehicle, comprising: electric brake fluid pressure generation means for generating brake fluid pressure by an electric motor; actual brake fluid pressure detection means for detecting an actual brake fluid pressure actually generated by the electric brake fluid pressure generation means; braking operation state detection means for detecting a driver braking operation state; target brake fluid pressure setting means for setting a target brake fluid pressure that is to be generated by the electric brake fluid pressure generation means according to the braking operation state; target rotational angle setting means for setting a target rotational angle for the electric motor that corresponds to the target brake fluid pressure; actual rotational angle detection means for detecting an actual rotational angle of the electric motor; electric motor control means for controlling actuation of the electric motor so as to make the actual rotational angle converge to the target rotational angle; communication means for transmitting at predetermined time intervals an actual brake fluid pressure detected by the actual brake fluid pressure detection means; and correction means for calculating a corrected value for correcting the target rotational angle for the electric motor based on a difference or a ratio of the target brake fluid pressure and the actual brake fluid pressure that is transmitted by the communication means and making the target rotational angle setting means output the target rotational angle which has been corrected by the corrected value.
