  • Patent number: 11720106
    Abstract: Examples described herein provide a computer-implemented method that includes defining, by a processing device, a plurality of parameters so that any orthogonal intersection can be described. The method further includes building, by the processing device, an orthogonal parameterized model that can represent any orthogonal intersection based at least in part on the plurality of parameters that can describe any intersection of interest. The method further includes expanding, by the processing device, the orthogonal parameterized model to generate a fully parameterized intersection model that accounts for intersection complexities. The method further includes building, by the processing device, a low-fidelity analytical that computes various metrics based on the fully parameterized intersection model.

  • Patent number: 10846952
    Abstract: A system and method for monitoring wheel hub temperatures and odometry in trailer axles. The system includes a spindle (118), an inner bearing (114), an outer bearing (116), a wheel hub (106) engaging the spindle (118) via the inner and outer bearings (114, 116), a thermocouple (108) positioned within the spindle (118), and an electronic control unit (112). The electronic control unit (112) is electrically coupled to the thermocouple (108) and configured to receive from the thermocouple (108), a temperature signal. The electronic control unit (112) is configured to determine, from the temperature signal, a temperature. The electronic control unit (112) is configured to compare the temperature to a predetermined threshold. The electronic control unit (112) is configured to, when the temperature exceeds the predetermined threshold, indicate a fault.

  • Publication number: 20200041304
    Abstract: A method for producing high resolution virtual wheel speed sensor data includes simultaneously collecting wheel speed sensor (WSS) data from multiple wheel speed sensors each sensing rotation of one of multiple wheels of an automobile vehicle. A camera image is generated of a vehicle environment from at least one camera mounted in the automobile vehicle. An optical flow program is applied to discretize the camera image in pixels. Multiple distance intervals are overlayed onto the discretized camera image each representing a vehicle distance traveled defining a resolution of each of the multiple wheel speed sensors. A probability distribution function is created predicting a distance traveled for a next WSS output.

  • Patent number: 8412435
    Abstract: A system, method and computer program product is provided for detecting if a vehicle has spun. A normal force and a lateral force of each of a front and rear axle of a vehicle is estimated. A coefficient of friction representative of a surface is estimated. Lateral momenta of the front and rear axles based on the coefficient of friction and the normal and lateral forces is calculated. Whether a surplus momentum is present, is determined. If the surplus momentum is present, a yaw rate of the vehicle is integrated respect to time to obtain a vehicle rotation estimation.

  • Patent number: 8165769
    Abstract: A method of estimating a speed of a vehicle is provided. The vehicle has a wheel and the method comprises receiving a first wheel speed signal indicating a rotation rate of the wheel, determining a first calculated forward speed of the vehicle based on the first wheel speed signal, receiving a first steering signal, determining the first steering signal contains information indicating large steering activity, receiving a second wheel speed signal at a later time than the first wheel speed signal, and determining, in response to receiving the first steering signal, a second calculated forward speed of the vehicle that is based on the second wheel speed signal and the first calculated forward speed.

  • Patent number: 7813890
    Abstract: A system, method and computer program product is provided for detecting if a vehicle is stopped. A wheel speed, transmission output speed, and a vehicle state, representative of a plurality of vehicle dynamic parameters, is determined. The vehicle is determined to be stopped if, after a predetermined period of time, the wheel speed and transmission output speed remain zero and the vehicle state remains stable.
