Abstract
An electronic braking device is provided which easily generates a braking force depending on the amount of brake operation in a range in which the amount of brake operation is small, just after the start of brake operation, and which protects a fluid pressure sensor from a fluid pressure beyond its tolerance. The electronic braking device activates a brake caliper through an electronic control unit (ECU) according to a signal in response to a braking request from a driver, and is provided with a first pressure sensor and a second pressure sensor for detecting the requested braking amount. The first pressure sensor and the second pressure sensor are different from each other in detection resolution and detection range. A relief valve unit r is provided which, when a fluid pressure above a prescribed level is applied to the master cylinder, relieves this fluid pressure.
