A powering pattern representing velocity of a vehicle at each position of a powering interval in a braking delay period between a timing at which the vehicle exceeds allowable velocity and a braking timing at which the vehicle starts to brake, and a coasting pattern representing velocity of the vehicle at each position of a coasting interval subsequent to the powering interval in the braking delay period are calculated after calculating a braking pattern representing velocity of the vehicle in a braking interval, which is a running interval subsequent to the coasting interval and which occurs between a position of the vehicle at the braking timing and a target position for controlling the vehicle to run at predetermined velocity or less, wherein an acceleration characteristic depending on velocity of the vehicle is used to calculate at least the powering pattern.

Disclosed is a method for actuating a parking brake system in a utility vehicle. In an example, the parking brake system includes an operational actuator for actuating a parking brake and a control unit for controlling the operational actuator. When the utility vehicle is stopped, a stored brake-application characteristic is selected for the parking brake as a function of a current vehicle condition of the utility vehicle. Based on the selected application characteristic, the operational actuator is activated by the control unit in order to apply the parking brake. In addition, or alternately, when the utility vehicle is started, a stored brake-release characteristic is selected for the parking brake as a function of a current vehicle condition of the utility vehicle. Based on the selected brake-release characteristic, the operational actuator is activated by the control unit in order to release the parking brake.

A trailer brake system that generates load-dependent braking forces. Variable trailer load information is used to generate load-dependent control signals which serve to control an electrically-controlled proportional valve. A load sensing valve serves to modify brake command signals in dependence on a control pressure that is regulated by the proportional valve.

An ECU operating as a vehicle control device, to be mounted on a truck tractor, has a hauling determination part and an automatic driving control part. The truck tractor is hauling/pulling a trailer. The hauling determination part detects whether the trailer is hauled by the truck tractor. The automatic driving control part switches an automatic driving mode between a first automatic driving mode and a second automatic driving mode on the basis of a detection result of the hauling determination part. The first automatic driving mode represents a situation in which the truck tractor is not hauling/pulling the trailer. The second automatic driving mode represents a situation in which the truck tractor is hauling/pulling the trailer.

An aircraft system for an aircraft having a controller configured to determine, based on a criterion indicative of an aircraft condition or a runway condition, a maximum braking level able to be applied to a brake of the aircraft in an emergency braking mode.

A machine includes an engine, a brake system, a speed sensor, a grade sensor, a load sensor, and a controller. The controller is configured to: determine a grade force based on the weight of the machine and the grade at which the machine is disposed; determine a deceleration force based on a target deceleration and the weight of the machine; monitor the speed at which the machine is traveling; determine an actual deceleration of the machine based on the monitored speed at which the machine is traveling; determine a deceleration error based on a difference between the actual deceleration and the target deceleration; determine a force correction based on the deceleration error; and control the brake system to apply a total brake force equal to the sum of the grade force, the deceleration force, and the force correction.

A vehicle crane having a hydropneumatic suspension and a braking system including wheel brakes and a first braking circuit assigned to the wheel brakes of at least one vehicle axle and a second braking circuit assigned to the wheel brakes of at least one other vehicle axle. In order to adapt the actuation of the braking system to the weight state, the hydropneumatic suspension is coupled to an automatically load-dependent braking force regulator that is operatively connected to one of the braking circuits or to one of their braking circuit sections such that, on the basis of a weight state signal of the vehicle crane generated from the hydropneumatic suspension, a braking pressure generated inside the braking circuit or braking circuit section coupled to the automatically load-dependent braking force regulator, can be varied with respect to a braking pressure generated simultaneously inside the other braking circuit or braking circuit section.
