Each RDC may include one or more suitably configured sensors e. Although not depicted in FIG. RDCs may forward the measured data and the accelerometer data to brake control unit for processing and generation of brake actuator signals for wheel brake mechanisms In example embodiments, brake control unit is suitably configured with antiskid control algorithms that utilize the accelerometer data to determine how best to generate brake actuator signals in response to the current conditions detected by RDCs RDC may generally include a processing architecture , a suitable amount of memory , a data communication module , an accelerometer , and one or more sensors These components and modules may be coupled together via a bus or any suitable interconnection arrangement.

Processing architecture is suitably configured to support the functionality of RDC , and to carry out the various tasks, methods, and processing steps described herein. Processing architecture and the various illustrative blocks, modules, processing logic, and circuits described in connection with the embodiments disclosed herein may be implemented or performed with a general purpose processor, a content addressable memory, a digital signal processor, an application specific integrated circuit, a field programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described herein.

A processor may be realized as a microprocessor, a controller, a microcontroller, or a state machine. A processor may also be implemented as a combination of computing devices, e. Memory is generally configured to store data necessary to support the functionality of RDC In this regard, memory may be coupled to processing architecture such that processing architecture can read information from, and write information to, memory In the alternative, memory may be integral to processing architecture As an example, processing architecture and memory may reside in an ASIC.

In the example implementation, data communication module accommodates transfer of data from RDC to the brake control unit of the aircraft. In addition, data communication module may be configured to receive sensor input s from any number sensors or sources that are external to RDC As explained previously, accelerometer is generally configured to measure acceleration of RDC relative to one or more designated directions. In this regard, FIG.

In the example embodiment, sensors are internal to RDC Sensors include a wheel speed sensor, which is configured to generate a speed value for the respective wheel of the aircraft, and a rotation sensor, which is configured to generate a rotational direction value for the wheel.

Sensors are coupled to processing architecture , which processes the measured data to automatically configure RDC in the manner described herein.

If the magnitude of the wheel speed exceeds the threshold, then RDC assumes that the aircraft is traveling forward and assigns a forward orientation to the rotational direction CW or CCW. Process facilitates automatic detection of the direction of motion of an aircraft having axle-mounted RDCs. Process also facilitates automatic configuration setup of axle-mounted RDCs having configurable accelerometers. The various tasks performed in connection with process may be performed by software, hardware, firmware, or any combination thereof For illustrative purposes, the following description of process may refer to elements mentioned above in connection with FIGS.

In embodiments of the invention, portions of process may be performed by different elements of the described system, e. It should be appreciated that process may include any number of additional or alternative tasks, the tasks shown in FIG. Indeed, process may run continuously so long as the aircraft remains powered up. In the example embodiment, process may be performed by each rear landing gear RDC on the aircraft.

Process may begin by generating or obtaining at the RDC the current wheel speed value for the respective wheel of the aircraft task The speed value may indicate an RPM value, a radians per second value, a linear feet per second value, or the like. In addition, process generates or obtains at the RDC the current rotational direction of the wheel task In this regard, process may compare the current wheel speed value to a threshold value query task The threshold value represents a speed that is indicative of forward movement of the aircraft.

For example, the threshold value may be indicative of a speed that is exceeded during forward taxi maneuvers or forward takeoff procedures, where that speed is not exceeded during reverse taxi maneuvers. Reverse taxi maneuvers rarely, if ever, exceed miles per hour.

Accordingly, the wheel speed comparison may be performed during aircraft taxi maneuvers—if the threshold value is set at 10 miles per hour and the measured wheel speed exceeds that threshold, process can safely assume that the aircraft is traveling in the forward direction. If query task determines that the wheel speed does not exceed the threshold, then process may return to task to continue monitoring the wheel speed and the rotational direction.

In other words, if the wheel speed does not exceed the threshold, process will leave the direction of motion undefined. Denunciar este documento. Fazer o download agora mesmo.

The agency is proposing performance requirements that new large buses of these types must meet in a test in which the vehicle is tipped over from an millimeter mm raised platform onto a level ground surface. This final rule is effective on November 9, Without a mandate to require and standardize V2V communications, the agency believes that manufacturers will not be able to move forward in an efficient way and that a critical mass of equipped vehicles would take many years to develop, if ever.

It will now end on December 10, Petitions for reconsideration of this final rule must be received not later than November 13, You should submit your comments early enough to ensure that the docket receives them not later than November 7, We believe there is widespread conformance of vehicles to the proposed requirements.

Each door and striker is mounted to the test fixture to correspond to its orientation on the vehicle and to the directions specified in b 1 ii of this paragraph. Orient the vehicle so that its longitudinal axis is aligned with the axis of the acceleration device, simulating a frontal impact. The section you are viewing is cited by the following CFR sections.

Stamdard will create an information environment in which vehicle and device manufacturers can create and implement applications to improve safety, mobility, and the environment. You should submit comments early enough to ensure that Docket Management receives them not later than March stanndard, The comment period for the request for comment published January 18,at 83 FRstandxrd extended. Additional Documents type regulations. Petitions for reconsideration of this final rule must be received not later than December 14, Annex ll specifies requirements for door locks and door retention components including latches, hinges and other supporting means, to minimize the lilelihood of occupants being thrown from the vehicle as a result of impact.

The Agency also seeks comments from road users, including vehicle drivers and passengers, cyclists and pedestrians. For test purposes, the load is to be applied equidistant between the linear center of the engaged portions of the hinge pin and through the centerline of the hinge pin in the transverse vehicle direction.

We believe that, by requiring that ESC systems be installed on the rest of truck tractors and large buses, this final rule will prevent 40 to 56 percent of untripped rollover crashes and 14 percent of loss-of-control crashes.
