Abstract:
1. A vehicular brake hydraulic pressure control device comprising: first operation unit that is provided with a first brake operation element; a first brake system that operates a first wheel brake in response to the first operation unit; a first control valve unit that is provided at the first brake system and controls brake hydraulic pressure in the first brake system; a second operation unit that is provided with a second brake operation element; a second brake system that operates a second wheel brake in response to the second operation unit; and a second control valve unit that is provided at the second brake system and controls brake hydraulic pressure in the second brake system, wherein the first operation unit and the first brake system are separated so as not to flow brake fluid therebetween, and wherein a brake fluid tank having a reservoir function is provided for supplying the brake fluid to the separated first brake system, wherein the first operation unit corresponding to the first brake system comprises: wherein the first brake system comprises a pump that discharges the brake fluid to at least a first wheel hydraulic pressure passage communicating to the first wheel brake in order to correspond to the operation amount detected by the detection unit, and wherein the first control valve unit comprises: wherein the detection sensor comprises a stroke sensor or a load sensor connected to a rod, wherein the stroke sensor detects an operation amount or operation force of the first brake operation element that corresponds to the first brake system, and wherein the stroke simulator includes a dummy cylinder comprising:
