Abstract:
1. An electric brake system using an electric motor to operate an electric brake, comprising: a target brake force setting portion for setting a target brake force corresponding to the amount of operation of a brake operating member; a target value setting portion for setting a target value for an output of said electric brake for generating the target brake force set by said target brake force setting portion; overshoot detection portions for operating said electric brake to produce the output of said target value from said electric brake, and detecting occurrence of overshooting when an actual control variable for the electric brake overshoots said target value; an actual control variable determination portion for determining the actual control variable in said electric brake when said overshoot detection portion detects the overshooting; and a target value correction portion for increasing the target value set by said target value setting portion to move toward said actual control variable in said electric brake determined by the actual control variable determination portion when said overshoot detection portion detects the overshooting.
