Controlling aircraft wheel brakes
A method for controlling the application of aircraft wheel brakes including: controlling the application of a first wheel brake of an aircraft and a second wheel brake of the aircraft in dependence upon a determined relationship to control the time taken for the first wheel brake and the second wheel brake to reach respective specified temperatures. The relationship is determined between a first cooling characteristic of the first wheel brake, according to which the first wheel brake cools when in a first retracted position within the aircraft, and a second cooling characteristic of the second wheel brake, according to which the second wheel brake cools when in a second retracted position within the aircraft.
VEHICLE BRAKING DEVICE
A vehicle braking device includes: a first hydraulic pressure output unit that is connected to a master chamber through a first liquid passage and outputs hydraulic pressure to first wheel cylinders based on a hydraulic pressure of the first liquid passage; a hydraulic pressure generating unit that generates hydraulic pressure independently of a master cylinder; a second hydraulic pressure output unit that is connected to the hydraulic pressure generating unit through a second liquid passage and outputs hydraulic pressure to second wheel cylinders based on a hydraulic pressure of the second liquid passage; a normally closed communication control valve that is provided in a communication passage connecting the first liquid passage and the second liquid passage and opens and closes the communication passage; and a normally open master cut valve in the first liquid passage on the master cylinder side relative to a connection portion with the communication passage.

BRAKE MONITORING SYSTEMS FOR RAILCARS
A system and method for detecting the operational status of a brake system on a railcar. The system receives from a sensor an indication of the magnitude of a braking force applied by the braking system in response to an instruction to increase or decrease the braking force. It compares the response to possible responses of the braking system in view of the instruction provided. Based on the comparison, the system generates at least one of a message and/or an alert indicating the status of the brake system. Additional sensors, including a pressure sensor on a brake pipe of the railcar, can be added for additional functionality.
PREVENTING UNWANTED TRAILER MOVEMENT
Braking of a vehicle and a trailer can be balanced when regenerative braking of the vehicle is activated. The activation of regenerative braking of the vehicle can be detected. Responsive to detecting that regenerative braking of the vehicle is activated, one or more brakes of the trailer can be caused to be activated. Thus, the braking effectiveness of the vehicle and the braking effectiveness of the trailer can be substantially balanced. As a result, a possible push force from a trailer to the vehicle towing the trailer can be reduced, which, in turn, can help to avoid unwanted movements of the trailer (e.g., swaying or jackknifing).
VEHICLE PARK-LOCK CONTROL METHOD AND PARK-LOCK CONTROL DEVICE
A vehicle park lock control method is presented with range positions including a P-range position and an N-range position in each of which a driving force is prevented from being transmitted to a driving wheel of a vehicle. A park lock mechanism is activated when in the P-range position. An operator is allowed to select whether or not to cause the park lock mechanism to be activated in response to key-off operation when in the N-range position. In response to continuous shifting of a range selector to one or more specific ones of the range positions, the park lock mechanism is prevented from being activated in response to key-off operation when in the N-range position.
Vehicular collision avoidance system
A vehicular collision avoidance system includes a forward-viewing camera, a rearward-viewing camera, a rearward-sensing non-vision sensor and an electronic control unit. The vehicular collision avoidance system detects vehicles present forward and/or rearward of the equipped vehicle. Responsive to at least one selected from the group consisting of (i) data processing of image data captured by the rearward-viewing camera and (ii) data processing of sensor data captured by the rearward-sensing non-vision sensor, the vehicular collision avoidance system detects another vehicle approaching the equipped vehicle from the rear, determines that the other vehicle is traveling in the same traffic lane as the equipped vehicle, determines speed difference between the vehicles, and determines distance from the equipped vehicle to the other vehicle. Based on such determinations, the system determines that impact with the equipped vehicle by the other vehicle is imminent.
