A hydraulic-pressure control circuit (40) in this vehicular hydraulic brake device (100) is provided with an electrical hydraulic-pressure source (41) and solenoid valves (V1, V2, V6, V7) that an electric control device (50) controls in accordance with the actuation amount of a brake-operating member (10). Said electric control device (50) is provided with the following: a mode determination means that determines whether or not a condition under which to keep the brake applied is met; a normal-mode control means that, if said condition is not met, keeps the electrical hydraulic-pressure source operating, controls the solenoid valves in accordance with the actuation amount of the brake-operating member, and controls the pressure inside a resistance-generating hydraulic chamber (C1) and the pressure inside a brake-driving hydraulic chamber (C2); and an economy-mode control means that, if the aforementioned condition is met, keeps the electrical hydraulic-pressure source stopped, maintains the solenoid valves in a set state, and maintains the pressure inside the resistance-generating hydraulic chamber (C1) and the pressure inside the brake-driving hydraulic chamber (C2) as is. This makes it possible, when a given brake actuation has been maintained for a duration greater than or equal to a set duration, to keep the brake applied with the electrical hydraulic-pressure source in the hydraulic-pressure control circuit stopped. |
