Abstract
In a vehicle including an automatic traveling device such as an auto-cruising device, an auto-following device, an auto-steering device and the like, which is capable of maintaining traveling of the vehicle in a state in which a driver has released his or her foot from an accelerator pedal, a relief valve and an on-off valve are incorporated in parallel in a pipeline which connects a master cylinder (2) and brake calipers. The closing of the on-off valve (6) during operation of the automatic traveling device ensures that even if the driver merely puts his or her foot on a brake pedal, a hydraulic braking pressure is not transmitted unless a depression force sufficient to permit the hydraulic braking pressure to exceed an opening pressure for the relief valve (5) is applied. When the driver applies a depression force on the brake pedal, the relief valve is opened, causing the brake caliper to generate a braking force, whereby the on-off valve is opened, and the operation of the automatic traveling device is released. Thus, a place for the driver to put his or her foot can be ensured without impairing the function of the automatic traveling device.
