Description / Abstract: Purpose. The purpose of this standard is to determine the performance of a vehicle equipped with a hydraulic brake boost system. This standard may be used for development or validation of requirements within the GM Vehicle Technical Specification (VTS) and for regional regulations.
Three (3) different technical conditions of hydraulic brake boost systems are considered: connected booster and valid vacuum sensor (normal system), connected booster and invalid sensor (normal vacuum and faulted sensor) and depleted brake booster and invalid vacuum sensor (zero vacuum and faulted sensor).
