To provide a vehicle brake apparatus which prevents deviation of heat to a specific phase of a multi-phase motor during lock energization to keep brake force of a dynamo-electric brake constituted by a multiphase motor.SOLUTION: A vehicle brake apparatus is mounted on a four-wheel vehicle in which a plurality of dynamo-electric brakes are installed on respective wheels to generate brake force for wheels corresponding thereto. The vehicle brake apparatus includes a brake force control part which controls brake force generated in the respective dynamo-electric brakes. At least one of a pair of dynamo-electric brakes corresponding to frontside right and left wheels and a pair of dynamo-electric brakes corresponding to rearside right and left wheels among the plurality of dynamo-electric brakes is a three-phase (multiphase) dynamo-electric brake constituted by a three-phase (multiphase) motor. The brake force control part executes "up-and-down processing" which increases or decreases brake force command value to the three-phase (multiphase) dynamo-electric brake based on reference value while keeping brake force so as to prevent a current from concentrating at a specific phase of the three-phase (multiphase) motor.SELECTED DRAWING: Figure 6

    【課題】多相モータで構成された電動ブレーキの制動力保持によるロック通電時に特定の相に発熱が偏ることを防止する車両用制動装置を提供する。【解決手段】車両用制動装置は、対応する車輪に制動力を発生させる複数の電動ブレーキが各車輪に設けられた四輪車両に搭載される。車両用制動装置は、各電動ブレーキが発生させる制動力を制御する制動力制御部を備える。複数の電動ブレーキのうち、前列左右輪に対応する一対の電動ブレーキ、又は、後列左右輪に対応する一対の電動ブレーキのうち少なくとも一方は、三相(多相)モータで構成された三相(多相)電動ブレーキである。制動力制御部は、制動力が保持されている時に三相(多相)モータの特定相に電流が集中しないように、三相(多相)電動ブレーキへの制動力指令値を基準値に対して増減させる「アップダウン処理」を実行する。【選択図】図6
