摘要： PROBLEM TO BE SOLVED: To improve the braking feeling and reduce the cost. SOLUTION: In this electric brake device 10, a digital converter 14 converts the depression force of a brake pedal 12 into an electric signal, and a controller 2 increases the torque of a driving motor 16 in accordance with the increase of the depression force on the basis of the electric signal to increase the vehicle braking force in accordance with the increase of the depression force. Here, a voltage switching device 24 is operated to reduce the fluctuation of the torque to the fluctuation of the depression force in an area of low depression force, whereby the fluctuation of the vehicle braking force to the fluctuation of the depression force can be reduced in the area of low depression force. That is, in the area of low depression force, the delicate difference of the depression force brings the delicate difference in the vehicle braking force, so that the braking of the vehicle can be finely executed in ordinary braking, and the braking feeling can be improved. As this device dispenses with a digital converter of high accuracy used in a conventional device, the cost can be reduced.

摘要： PROBLEM TO BE SOLVED: To achieve a fail-safe control effectively and inexpensively, when the power voltage of a brake device drops. SOLUTION: A brake ECU 200 adjusts feed amount of an operation fluid discharged from pumps 32-38 to wheel cylinders 20 while blocking the feed of the operation fluid from the pumps 32, 36 to a master cylinder 14, by driving motors 40, 42 while closing on-off valves 28, 30 and adjusting the opening of regulating valves 46-54 in a normal brake control condition. Meanwhile, the brake ECU 200 drives the motors 40, 42 to permit a part of the operation fluid discharged from the pumps 32, 36 to be fed to the master cylinder 14 even in a low voltage state where the power voltage is lower than the minimum operation voltage of the on-off valves 28, 30.

摘要： PROBLEM TO BE SOLVED: To provide a current supply circuit that detects a faulty regulator.
SOLUTION: The current supply circuit 110 includes: a first regulator 214 and a second regulator 224 arranged in parallel between a battery 300 and a simulator cut valve SCSS; a first current monitor 215 and a second current monitor 225 arranged in parallel; a first control part 216 for controlling the output current of the first regulator 214; and a second control part 226 for controlling the output current of the second regulator 224. When a failure of the first regulator 214 and the second regulator 224 is estimated, the first control part 216 and the second control part 226 cause the first regulator to output a predetermined first current pattern, and causes the second regulator 224 to output a predetermined second current pattern which is different from the first current pattern. Then, on the basis of the current pattern detected by the first current monitor 215 and the second current monitor 225, the faulty regulator is determined.
