VEHICLE BRAKE CONTROL DEVICE

To make it possible in a vehicle brake control device performing automatic brake control in which even if a malfunction occurs in any of the functions of the device, the device is made to operate properly.SOLUTION: In an automatic brake control, a first control unit EC1 of the present invention controls an electric cylinder YC to allow one of left and right front wheels to lock and not to allow the other to lock, with a front wheel contact valve VRf open and a front wheel isolation valve VMf closed, if a second control unit EC2 has failed. In the automatic braking control, if the first control unit EC1 has failed, the second control unit EC2 controls the electric cylinder YC to allow one of the right and left front wheels to lock and not to allow the other to lock, with a supply valve VH closed, a rear wheel connecting valve VRr open and a rear wheel isolation valve VMr open, without controlling front wheel regulating valves VIf and VOf, and controls rear wheel regulating valves VIr, VOr so that rear wheel regulating valves VIr and VOr are not locked.SELECTED DRAWING: Figure 1 【課題】自動制動制御が実行される制動制御装置において、装置の一部不調が発生した際でも、その実行が可能なものを提供する。【解決手段】本発明の第１制御部ＥＣ１は、自動制動制御において、第２制御部ＥＣ２が故障している場合、前輪連絡弁ＶＲｆを開弁させ前輪分離弁ＶＭｆを閉弁させた状態で、左右の前輪のうち一方のロックを許容し他方のロックを許容しないように電動シリンダＹＣを制御する。また、第２制御部ＥＣ２は、自動制動制御において、第１制御部ＥＣ１が故障している場合、補給弁ＶＨを閉弁させ後輪連絡弁ＶＲｒを開弁させ後輪分離弁ＶＭｒを開弁させた状態で、前輪調圧弁ＶＩｆ、ＶＯｆを制御せずに、左右の前輪のうち一方のロックを許容し他方のロックを許容しないように電動シリンダＹＣを制御し、且つ左右の後輪がいずれもロックしないように後輪調圧弁ＶＩｒ、ＶＯｒを制御する。【選択図】図１
