Hydraulic brake device for vehicle |
摘要 |
A hydraulic brake device for applying a braking force to a wheel of a vehicle which can detect an air-containing in a hydraulic circuit. The hydraulic brake device includes a hydraulic pressure generating device for generating and outputting a hydraulic pressure in accordance with a brake operational amount, a wheel cylinder operated by the hydraulic pressure directly or indirectly supplied from the hydraulic pressure generating device for applying a braking force to a vehicle wheel, a brake operational amount detection device for detecting the brake operational amount, a pressure sensor for detecting an output hydraulic pressure outputted from the hydraulic pressure generating device, and a controller for detecting an air-containing in a hydraulic circuit by a response time relating to a rise of the output hydraulic pressure detected by the pressure sensor relative to a start of a rise of the brake operation amount detected by the brake operational amount detection device.
