Abstract:
1. A vehicular braking control apparatus comprising: a master cylinder that generates a hydraulic pressure corresponding to a brake operating force; a first communication passageway that connects the master cylinder and a wheel cylinder of a braking apparatus in communication; a first open-close valve disposed on the first communication passageway; a stroke simulator that is connected to the first communication passageway between the first open-close valve and the master cylinder and that provides a reaction force corresponding to the brake operating force; a pressurization source that generates a predetermined hydraulic pressure; a hydraulic pressure adjusting portion that connects the pressurization source and the first communication passageway between the first open-close valve and the wheel cylinder and adjusts the hydraulic pressure applied to the wheel cylinder; a hydraulic pressure sensor that detects the hydraulic pressure on the first communication passageway between the first open-close valve and the master cylinder; and a control portion that, while a brake is not operated, closes the first open-close valve, and controls the hydraulic pressure adjusting portion so as to increase the hydraulic pressure on a wheel cylinder side of the first communication passageway while maintaining a closed state of the first open-close valve, and then opens the first open-close valve, and determines whether there is an abnormality of the stroke simulator based on a change in outputs of the hydraulic pressure sensor before and after the first open-close valve is opened.
