Abstract

An apparatus controls release of a parking brake of a parking brake system of an associated vehicle. A processor of an electronic control system of the apparatus executes parking brake control logic stored in a non-transient memory device to selectively generate a parking brake release (PBR) signal based on receiving a set of predetermined PBR interlock override signals in an absence of receiving fully all of a set of predetermined PBR interlock standard satisfaction signals, wherein receiving fully all of the set of predetermined PBR interlock standard satisfaction signals causes the processor executing the parking brake control logic to generate the PBR signal. The sets of predetermined PBR interlock override and interlock standard satisfaction signals are mutually different, and the PBR signal is deliverable for use by the associated vehicle to effect the release of the parking brake of the parking brake system of the associated vehicle.
