  • Patent number: 10525950
    Abstract: A braking controller and method in a towing vehicle towing one or more towed vehicles as a combination vehicle provides brake control of the one or more towed vehicles based on a level of braking force applied to the towing vehicle. A non-enhanced braking mode applies a first level of braking force to the towed vehicles in a predetermined reduced proportion relative to the level of braking force applied to the towing vehicle, and an enhanced braking mode applies a second level of braking force to the towed vehicles greater than the first level of braking force. The enhanced braking mode strategy is used unless trailer capability information reported by one or more the trailers fails to match against expected trailer capability information.

  • Patent number: 10482767
    Abstract: A platoon management control system and method for local detection and determination of a non-platooning vehicle inserted or otherwise disposed between and/or adjacent to one or more platooning vehicle(s). A platooning vehicle determines a forward physical distance between itself and a vehicle physically ahead, and compares the determined physical distance with a value of a rearward distance to the platooning vehicle received from a next ahead platooning vehicle. The vehicle physically ahead is determined to be the next ahead platooning vehicle in accordance with a correspondence between the determined physical distance and the received value of the rearward distance. Conversely, the vehicle physically ahead is determined to be a non-platooning vehicle in accordance with a mis-correspondence between the determined physical distance and the received value of the rearward distance.

  • Patent number: 10465637
    Abstract: An apparatus for improving exhaust gas recirculation performance is provided which induces improved exhaust gas recirculation flow during engine operating transients, including transients in which exhaust gas flow conditions are unfavorable. The apparatus includes a fresh air intake passage with a venturi section and an exhaust gas recirculation passage outlet, preferably in the form of a pitot tube, arranged in the fresh air intake passage adjacent to the venturi section such that a pressure-reducing flow in the fresh air is induced as a result of the Coand? effect. Establishing Coand? flow adjacent to the exhaust gas recirculation outlet substantially assists in drawing exhaust gas into the fresh air intake flow in transient operating conditions, including unfavorable exhaust-to-intake pressure difference conditions. The Coand? flow also assists in more rapid and thorough mixing the gases to provide a homogeneous mixture to minimize NOx production during engine operating transients.

  • Patent number: 10457263
    Abstract: When detecting a maladjusted brake component on a commercial vehicle, wheel end temperature is determined as a function of resistance measured by a wheel speed sensor at a wheel end. The measured temperature is compared to low and high temperature thresholds defined by a thermal model, as well as to one or more other wheel speed sensor temperatures. If the measured temperature is below the low temperature threshold and substantially different than the one or more other wheel speed sensors, the brake is determined to be under-adjusted and brake force at the under-adjusted brake is increased. If the measured temperature is above the high temperature threshold and substantially different than the one or more other wheel speed sensors, then the brake is determined to be over-adjusted, and brake force is reduced or modulated at the over-adjusted brake to prevent overheating.

  • Patent number: 10427681
    Abstract: A controller for a host vehicle having adaptive cruise control comprises control logic that determines an actual time gap behind a detected target object and transmits a deceleration message having a deceleration value in response to the actual time gap being less than a predetermined minimum time gap. The control logic receives a torque message from a vehicle retarder indicating that the vehicle retarder is at a limit. If the actual time gap is less than the predetermined minimum time gap, the control logic transmits a transmission control message requesting the transmission to shift to a lower gear. The control logic transmits another deceleration message if the actual time gap is still less than the predetermined minimum time gap, wherein at least one of an associated transmission and an associated braking system respond to decelerate the host vehicle in response to the transmission control message and deceleration messages.
