Abstract:
A brake fluid pressure control device, comprising:a controller; a fluid pressure control unit that operates in accordance with a control signal supplied from the controller and having a plurality of fluid pressure control valves capable of controlling fluid pressures in a plurality of brakes to inhibit rotation of a plurality of wheels; a plurality of signal lines that connect the fluid pressure control valves to the controller; wherein: the plurality of signal lines are divided into a plurality of signal line groups; the signal lines of a first one of the signal line groups are connected between the controller and the fluid pressure control unit by a first connector, and the signal lines of a second one of the signal line groups are connected between the controller and the fluid pressure control unit by a second connector; and the controller is directly connected to, at least, the first connector and the second connector for connecting the plurality of signal lines divided into a plurality of signal line groups, such that the controller outputs the signal lines of the first one of the signal line groups independently from the signal lines of the second one of the signal line groups, wherein the fluid pressure control unit includes a first linear valve device including at least one of the plurality of fluid pressure control valves, and a second linear valve device including the rest of the plurality of fluid pressure control valves, and if one of a first control system including the first connector and the first linear valve device, and a second control system including the second connector and the second linear valve device falls into an abnormal condition, at least one of the brakes is controlled via the connector of one of the first and second control systems which does not fall into the abnormal condition, rather than the connector of the other of the first and second control systems which falls into the abnormal condition.
