SYSTEM FOR CONTROLLING AIRCRAFT GROUND MANOEUVRES
An aircraft includes a ground maneuver control system that automatically steers a nose landing gear wheel to compensate for asymmetrical braking of the wheels of the aircraft resulting from a failure on one side in comparison to the other. A control system detects such a failure in order to be able to effect such automatic steering. The system may be retrofitted by the installation of software on an existing aircraft, having a braking and steering computer system with a pre-existing steering control functional block and a pre-existing braking control functional block.

The redundant control system applied to the BBW system includes electromechanical brakes (EMBs) provided at wheels of a vehicle and configured to perform brake control of the vehicle, controllers connected to the EMBs, respectively, and a local gateway on a first communication line configured to receive information on the vehicle and a command of a driver and to transmit the information on the vehicle and the command of the driver to the controllers, where the controllers are configured to receive the information on the vehicle and the command of the driver through a second communication line.
Fluidic control system
A fluidic control system (1) for controlling a vehicle, which includes a controller (2) and a closed fluidic circuit. The circuit includes a pump (3) for pressurizing fluid in the circuit, valve means (40, 50, 60), an actuator (4, 5, 6) and a precharge accumulator (7). The valve means (40, 50, 60) is fluidly connected to the inlet and outlet of the pump (3) and the actuator (4, 6) is fluidly connected to the valve means (40, 50, 60) for selectively receiving pressurized fluid therefrom. The precharge accumulator (7) includes a movable member (73, FIG. 2) that describes a variable volume (71) fluidly connected to the circuit between the valve means (40, 50, 60) and the inlet of the pump (3). The system (1) also includes a sensor (70) for determining the position of the movable member (73) for estimating the quantity of fluid and/or detecting an abnormal pressure variation within the circuit.
METHOD AND DEVICE FOR INFLUENCING A STEERING ELEMENT OF A SINGLE-TRACK MOTOR VEHICLE INDEPENDENTLY OF THE RIDER
A method includes ascertaining that an emergency braking operation of a single-track motor vehicle is to be automatically executed driver independently, and based on the ascertainment, automatically and driver-independently influencing a steering element of the motor vehicle during the execution of the emergency braking operation.
VEHICLE CONTROL SYSTEM, VEHICLE CONTROL METHOD, AND VEHICLE CONTROL PROGRAM
A vehicle control system includes: a first device that generates trajectory data indicating a future trajectory of a host vehicle and outputs the generated trajectory data; a second device that controls at least one of acceleration/deceleration and steering of the host vehicle on the basis of the trajectory data generated by the first device; and a third device that receives the trajectory data generated by the first device and writes the received trajectory data in a storage unit thereof, the third device being a device separate from at least the first device, wherein when an abnormality occurs in the trajectory data output by the first device, the second device controls at least one of acceleration/deceleration and steering of the host vehicle on the basis of the trajectory data which has been received by the third device and written in the storage unit before the abnormality occurred.
VEHICLE CONTROL APPARATUS
In a vehicle control apparatus which controls movement of the own vehicle, the control unit obtains data of surroundings of the own vehicle. Then, according to the data of the surroundings, the control unit conducts vehicle control including acceleration/deceleration control representing control related to acceleration/deceleration of the own vehicle, and steering control representing control related to steering of the own vehicle. Upon input of a stop command indicating stop of the vehicle control, a first stop section stops first control which is either of the acceleration/deceleration control and the steering control. Then, a second stop section stops a second control, which is the other of the acceleration/deceleration control and the steering control, at a timing different from the timing to stop the first control (S310).
A METHOD OF CONTROLLING A BACKUP MOTION CONTROL SYSTEM
A method of controlling a backup motion control system for an autonomous vehicle is provided. The autonomous vehicle includes a primary steering system for controlling steering operations of a pair of steerable wheels. Each of the steerable wheels comprises a wheel brake, the wheel brakes being connected to an anti-lock braking system for preventing the wheel brakes from being locked when the anti-lock braking system is arranged in an enabled state. The method includes determining a current motion for the autonomous vehicle, the current motion being generated by a steering operation of the pair of steerable wheels caused by the primary steering system; comparing the current motion with a desired motion for the autonomous vehicle; and when a difference between the current motion and the desired motion exceeds a predetermined threshold limit: controlling the anti-lock braking system for the wheel brakes of the steerable wheels to be arranged in a disabled state; and engaging the wheel brakes of each of the steerable wheels.
APPARATUS AND METHOD FOR CONTROLLING BRAKE SYSTEM IN CASE OF STEERING SYSTEM FAILURE
An apparatus for controlling a brake system includes: an upper controller generating calculating a first control signal so that a difference between a control target and a vehicle state is equal to or less than a threshold through state-feedback control; and a lower controller converting the first control signal into a braking torque for each of vehicle wheels, and distributing a braking pressure to actuators of the vehicle wheels through the brake system so that the braking torque for each which can be generated.

A controller for a work machine includes a steering control circuit, a memory, and a speed control circuit. The steering control circuit is configured to control a steering of the work machine to change a steering angle based on a travel route. The memory is to store a threshold angle. The speed control circuit is configured to control a speed of the work machine if the steering angle is equal to or larger than the threshold angle and if the steering control circuit does not control the steering.
Electric equipment of a vehicle, comprising an at least partly electric braking and steering device with high availability
A braking system and a method of operating such a braking system are provided for a vehicle having at least partly electric braking, a steering device containing an electric or electromechanical steering device, an electronic steering controller and an electric steering adjuster and containing a service brake device. The system includes an electropneumatic service brake device containing an electropneumatic service brake valve device, an electronic brake controller, electropneumatic modulators, pneumatic wheel brake actuators, a service brake actuating element, and at least one electric channel (130) with at least one electric brake value transmitter which senses activation of the service brake actuating element. The at least one electric brake value transmitter produces actuation signals which are relayed to the electronic brake controller. The electronic brake controller causes a first actuation force to be applied to at least one control piston of the service brake valve device to control at least one double seat valve of the service brake valve device to generate pneumatic braking pressures or brake control pressures for the pneumatic wheel brake actuators. The electronic controls are further configured to generate a second actuation force on the at least one control piston when a brake request independent of the driver's request exists, independent of a driver brake request.
