PROBLEM TO BE SOLVED: To suppress a rise in a starting current to be fed to a motor at an initial time of control initiation while feeding a current to the motor in a fully conducting state after control of an automatic brake is initiated.SOLUTION: By controlling a motor in a fully conducting state, the motor has its output raised high. While a high braking force is obtained with high responsiveness, the motor is controlled at a high frequency only when started. Thus, a starting current is inhibited from being excessive. Accordingly, a drop in a battery voltage can be suppressed, and a malfunction of a control system of various pieces of electrical equipment employed in a vehicle can be inhibited.SELECTED DRAWING: Figure 11
【課題】自動ブレーキの制御開始後にはモータへの電流供給をフル通電状態で行うようにしつつ、制御開始初期時にモータへの始動電流の上昇を抑制する。【解決手段】モータをフル通電状態で制御することでモータをより高出力化し、高い制動力を高い応答性で得られるようにしつつ、始動時のみ高周波制御することで始動電流が過大になることを抑制する。これにより、バッテリ電圧の低下を抑制することが可能となり、車両に使用されている各種電装品の制御システムの作動不良を抑制できる。【選択図】図11
