HYDRAULIC BRAKE UNIT AND CONTROL METHOD FOR SUCH A HYDRAULIC BRAKE UNIT

摘要

A hydraulic brake unit (120) includes: a manual hydraulic pressure supply unit (127) that pressurizes a hydraulic medium supplied from a reservoir (134) and generates a hydraulic pressure corresponding to a brake operation amount; first and second hydraulic systems (161, 162) in which the manual hydraulic pressure supply unit (127) communicates with first and second wheel cylinders (123F, 123R); a separation valve (160) provided between the first hydraulic system (161) and the second hydraulic system (162); and a brake ECU (170) having a separation valve control unit (110) and a hydraulic medium amount detection unit (Ilia), wherein the separation valve control unit (110) executes control to close the separation valve (160) when the hydraulic medium amount detection unit (Ilia) detects that the hydraulic medium stored in the reservoir (134) has decreased below a predetermined amount.
