Abstract:
1. A brake control system for a vehicle comprising: a master pressure controller having a first brake operation quantity sensor that detects a brake operation quantity for controlling a first driving motor that pressurizes working fluid of a master cylinder so as to increase a wheel cylinder pressure of each of a plurality of wheels of said vehicle; and a wheel pressure controller coupled to said master pressure controller through a communication line, for executing a control function that differs from a control function of said master pressure controller, said control function of said wheel pressure controller controlling a second driving motor to increase said wheel cylinder pressure of each of said wheels of said vehicle, said wheel pressure controller having a second brake operation quantity sensor that detects said brake operation quantity; wherein said wheel pressure controller further comprises: wherein said master pressure controller stops controlling said first driving motor upon a transmission of said failure information, or upon a failure of communication between said master pressure controller and said wheel pressure controller via said communication line, and wherein either one of said master pressure controller and said wheel pressure controller further includes a master pressure acquisition unit for acquiring a master pressure and a second failure detection unit for detecting said failure of said master pressure controller based on said brake operation quantity detected by said first or second brake operation quantity sensor and said master pressure acquired by said master pressure acquisition unit.
