A parking brake apparatus is provided for a power unit having air brake parking components and to which a towed unit having air brake parking components can be connected. The parking brake apparatus comprises a controller arranged to monitor a pressure signal indicative of a delivery air pressure applied to the air brake parking components of the towed unit when the towed unit is connected to the power unit. The controller is also arranged to provide a status signal indicative of whether or not a towed unit is connected to the power unit based upon the pressure signal. The controller further enables the status signal to be processed to control application or release of any combination of air brake parking components of the power unit and the towed unit to park or unpark the power unit as well as the towed unit, if connected to the power unit.

A brake controller in a vehicle determines braking profiles that may be exercised while operating the vehicle in autonomous or semi-autonomous conditions to decelerate the vehicle based on received commands or that may be exercised automatically in the event of a failure in a communication network of the vehicle or in other systems or components of the vehicle. The braking profiles decelerate the vehicle according to a deceleration profile. The execution of the deceleration profile may be initiated by a single command message received by the brake controller or it may be determined by the brake controller based on vehicle information. A safe state deceleration profile may be preselected by the controlling devices before the occurrence of a failure or an emergency situation, and then executed by the brake controller upon the occurrence of a failure or emergency.

An apparatus for controlling a trailer parking brake status indicator in a tractor is provided that allow an operator to deactivate the indicator when the tractor is operating without a trailer using a pre-existing operator interface. The apparatus includes means for determining whether a trailer is coupled to the tractor and a controller configured to execute, when a determination whether the trailer is coupled to the tractor cannot be made, a process for controlling activation and deactivation of the indicator. The process includes determining whether a speed of the tractor meets a predetermined condition relative to a predetermined speed. The process further includes monitoring, after determining that the speed of the tractor meets the predetermined condition relative to the predetermined speed, for an activation command to activate a parking brake on the trailer. The process further includes deactivating the trailer parking brake status indicator responsive to the activation command.

A method and controller are provided for delaying activation of autonomous emergency braking of a host vehicle, based on a determination that autonomous emergency braking is not needed because a forward vehicle in front of the host vehicle is turning out of the path of the host vehicle. The controller receives inputs from sensors arranged on the host vehicle and includes a processor for determining whether and when to activate autonomous emergency braking. The processor includes control logic that determines whether a forward vehicle is present in front of the host vehicle and whether the forward vehicle is expected to turn out of a path of the host vehicle prior to the host vehicle reaching a current position of the forward vehicle. Based on the inputs from the sensors, the control logic determines whether to delay activation of the autonomous emergency braking of the host vehicle for a time value.

A controller for an adaptive braking system on a host vehicle identifies a first target in a lane of travel of the host vehicle; monitors for an active braking intervention request; monitors for other targets in adjacent lanes of travel to the host vehicle; and transmits a first braking signal at the output to control a braking action at a first braking level in response to receiving the active braking intervention request and identifying no other targets in adjacent lanes of travel to the host vehicle. If the controller identifies a second target in an adjacent lane of travel, then receives a travel signal indicative of change in the direction of travel of the host vehicle toward the second target; it will transmit a second braking signal to control the braking action at a second braking level. The second level of braking is different than the first level of braking.
