  • Patent number: 10759428
    Abstract: A vehicle includes one or more laser scanners and an on-board vehicle computer system communicatively coupled to the laser scanners. The computer system uses information (e.g., coordinate points) obtained from the laser scanners to calculate a trailer angle (e.g., a cab-trailer angle) for the vehicle. The computer system may include a shape detection module that detects a trailer based on the information obtained from the laser scanners and an angle detection module that calculates an angle of the detected trailer relative to a laser scanner, calculates the orientation of the detected trailer based on that angle and dimensions (e.g., width and length) of the trailer, and calculates a cab-trailer angle based on the orientation of the trailer. The computer system may include an autonomous operation module configured to use the cab-trailer angle in an autonomous or computer-guided vehicle maneuver, such as a parking maneuver or backing maneuver.

  • Patent number: 9429070
    Abstract: System and method for starting a turbine engine are disclosed. These systems and methods for starting a turbine engine may be located on a vehicle, such as such as a Class 8 vehicle, equipped with a turbine engine as the prime mover or as a generator in a hybrid powertrain. In that regard, a fluid forcing device may be employed to start the turbine engine, such as an electric pump/compressor. The fluid forcing device may already be located on the vehicle for other purposes, and can include an electrically powered steering pump (also referred to as an electric pump) or an electrically powered air brake compressor (also referred to as an electric compressor). In order to start the turbine engine, the output of the electric pump/compressor drives an associated fluid circuit, which in turn, supplies fluid over a portion of the turbine shaft, wheel or scroll in order to impart rotational motion thereto. The rotational motion imparted to the turbine shaft, wheel or scroll aims to start the turbine engine.

  • Publication number: 20100056326
    Abstract: A steering system generally includes a steering gear for controlling a steer axle of the a hybrid vehicle in response to rotation of a steering wheel. The steering system also includes a power steering pump functionally connected to an internal combustion engine for supplying pressurized fluid to the steering gear. The steering system further includes an accumulator, a power steering controller, and a pressure sensor for monitoring the pressure of the accumulator. In use, the steering system continuously monitors the pressure of the accumulator via the pressure sensor. In several instances, the steering system keeps track of whether the accumulator pressure exceeds an engine shut-down prohibition level and/or an engine restart level. From these signals, the internal combustion engine can be instructed to restart from its engine-off condition and/or the internal combustion engine can be prohibited operating in its engine-on condition to transition to its engine-off condition.

  • Publication number: 20100050671
    Abstract: Climate control systems are provided that are suitable for providing climate control functionality to a hybrid vehicle. The system is capable of operating in dual modes, depending on the present operational state of the vehicle. For example, the dual modes may be as follows: (1) when the vehicle is currently in transit, including intermittent stops, the climate control system is capable of operating at its maximum output, as requested, for cooling the passenger compartment of the vehicle; and (2) when the vehicle is not in transit (e.g., when parked) the climate control system operates at a reduced capacity in order for the climate control system to be powered by the energy storage device for a set period of time. The climate control system may reduce the capacity based on energy reserve levels in the energy storage device.

  • Publication number: 20100057281
    Abstract: Information display systems present information that allows the driver to increase fuel efficiency of a vehicle, such as a hybrid vehicle. In one example, the systems present information in a manner that allows the driver to maximize the time that the hybrid vehicle is able to operate in electric launch mode. One manner is employing a graphical display that generates visual indicators and easily understood graphical representations that display the actual fuel efficiency currently being achieved in comparison to the driver's application of the throttle. As a result, the driver may be able to modify driving habits in order to keep the hybrid vehicle in electric launch mode for as long as possible.
