摘要:
A hub-mountable wheel-rotation detector has an electromagnetic generator to convert rotational mechanical energy into electrical energy sufficient to recharge an internal rechargeable battery and power internal alarm and distance-tracking circuitry. The detector provides a combination of backup alarm and hubodometer functionality in a common device.

Vehicles, systems, and methods for determining a distance travelled are provided. In an exemplary embodiment, a vehicle includes an electric motor with a motor rotor shaft. A motor resolver is positioned adjacent to the motor rotor shaft, where the motor resolver is configured to determine a motor position of the electric motor based on revolutions of the motor rotor shaft. A controller is in communication with the motor resolver, where the controller is configured to determine a distance travelled from a change in the electric motor position.

Embodiments are directed to a computer-implemented method of generating data of a vehicle. The method includes tracking, using a processor system, mileage data that represents a number of miles driven by the vehicle. The method further includes storing, using a memory system, the mileage data. The method further includes tracking, using the processor system, operating data that represents how the vehicle has been operated. The method further includes storing, using the memory system, the operating data. The method further includes generating, using the processor system, a map that maps relationships among the mileage data and the operating data.

A travel distance measurement device includes a transmitting antenna that is disposed in a vehicle and emits a transmission signal, as a radio wave, toward a ground surface, a receiving antenna that is disposed in the vicinity of the transmitting antenna, and receives a radio wave reflected from the ground surface and acquires a reflection signal, and a distance calculator (an IQ demodulator and a phase conversion integrator) that calculates the travel distance of the vehicle on the basis of the phase of the acquired reflection signal.

A vehicle control system includes a computer and logic executable by the computer. The logic is configured to read an odometer value from a storage system. The odometer value corresponds to an accrued mileage obtained from an odometer. The accrued mileage is determined at a beginning of a current driving event. The logic is also configured to read an odometer value for the vehicle from another storage system. The odometer value from the other storage system corresponds to an accrued mileage obtained from the storage system at the beginning of a driving event that precedes the current driving event. The logic is further configured to compare the odometer value from the storage system to the odometer value from the other storage system and calculate a reduction value from the difference, upon determining the odometer value from the other storage system is greater than the odometer value from the storage system.

In an adjustment mode, a control unit of a display control device displays, on a display, frame bodies imitating shapes of measuring instruments, and changes the display positions or/and the shapes at which or in which the frame bodies are displayed on the basis of input operation received by the input unit, and stores, to the parameter storage unit, the determined display positions or/and the determined shapes of the frame bodies as parameters of the display positions or/and the shapes of the measuring instruments.
摘要:
A system for measuring the relative distance between pipeline pigs moving in a pipeline is provided. The system includes a means for measuring the relative distance between the pipeline pigs as the pigs move through the pipeline to enable a determination of the change of the relative distance between the pigs as they move through the pipeline. In an embodiment, the relative distance between the pigs is measured and recorded using one or more transceivers carried by one or more pigs. Other embodiments for measuring and recording the relative distance between pigs moving in a pipeline are also disclosed.

Apparatus and methods for calibrating dynamic parameters of a vehicle navigation system are presented. One method may include determining whether reference position data of a vehicle is available, and measuring composite accelerations of the vehicle. The method may further include generating distance and turn angle data based upon a wheel speed sensors data, computing distance and turn angle errors based upon the independent position data, and associating the distance and turn angle errors with composite accelerations. A second method presented includes calibrating an inertial navigation sensor within a vehicle navigation system. The second method may include determining reference position data and Inertial Navigation System (INS) data, aligning an IMU with the vehicle, and aligning the IMU with an Earth fixed coordinate system. The second method may further include computing the vehicle alignment with respect to a horizontal plane, and determining calibration parameters for distance sensors associated with the vehicle.
摘要:
A display system is provided for a trailer equipped with an electronic braking system (EBS) and/or an anti-lock braking system (ABS). A separate display device having a display is provided for indicating at least the mileage on the trailer vehicle. In order to reduce the amount of wiring required, a speed signal of at least one of the wheels of the trailer is looped through the EBS/ABS and is routed directly to the display device.
