A brake control system for a vehicle includes primary and secondary controllers that control components of a fluid circuit. The fluid circuit includes a parking brake valve module and two solenoid valves controlling fluid flow to the module from two fluid sources. A double check valve in the module passes the greater fluid pressure which is measured by a pressure sensor. The secondary controller performs, prior to any failure of the primary controller, a diagnostic test. The secondary controller receives signals indicative of fluid pressure in each fluid source and the module. When the fluid pressures of the fluid sources differ, the secondary controller blocks the valve coupled to the higher pressure fluid source, compares the measured fluid pressures in the module and one of the fluid sources and, depending on the results of the comparison, generates an alert regarding the valve coupled to the lower pressure fluid source.

Braking control apparatus and method determining trailer brake pressure model based on trailer information
Default trailer model data stored in a memory device of a braking control apparatus is used to generate a default trailer braking signal for activating brakes on a default towed vehicle. An application trailer braking model different than the default trailer braking model is determined based on application trailer configuration data alone or in combination with the default trailer braking model. The application trailer configuration data is representative of an application value of an equipment parameter of the towed vehicle. Compensated trailer braking control data is determined by applying primal trailer braking control data representative of a primal trailer braking control signal to the determined application trailer braking model, and an output circuit generates a compensated trailer braking control signal for delivery to a modulator valve that is responsive to the compensated trailer braking control signal to activate brakes on the towed vehicle.
A braking controller causes a tractor protection control module in a tractor to prevent air flow from an air reservoir to a gladhand when the braking controller determines that the trailer is not pneumatically coupled with the gladhand. This prevents air from being vented out the gladhand when the tractor's service brakes are applied. The braking controller can detect pneumatic discontinuity, for example, by receiving a notification from a parking brake controller or from a pressure sensor in the tractor protection control module.
An electronically-controlled tractor protection control module in a tractor prevents air flow from an air reservoir to a gladhand when a signal is received that indicates a trailer is not coupled with the gladhand. This prevents air from being vented out the gladhand when the tractor's service brakes are applied. However, a failure can occur that prevents this signal from being received or acted upon, which would result in air being vented out the gladhand. To address this problem, an air flow restrictor is used to limit the amount of air that is vented in such a situation.

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.
