  • 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: 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.

  • Publication number: 20190196501
    Abstract: Platoon management control systems and methods arrange two or more vehicles cooperatively travelling seriatim as a platoon along an associated roadway into a platoon arrangement in accordance with their relative braking capabilities and other brake-related performance characteristics such as braking efficiency. Braking efficiency can change over time and is in general affected by many factors such as brake temperature, brake type, burnishing, vehicle weight, number of tires, tire wear, vehicle loading, road surface type and weather conditions. The relative braking capabilities are learned or otherwise calculated or determined in each vehicle and shared between the vehicles of the platoon. The platoon may be reorganized based on differences between the learned or otherwise calculated or determined relative braking capabilities.

  • Publication number: 20190126712
    Abstract: When a vehicle is determined to be traveling on a rough road, wherein increased air consumption is expected by vehicle components, a warning threshold that triggers an alert regarding excessive air consumption is increased. A duty cycle for an on-board air compressor is also increased to a level just below the increased warning threshold. In this manner, the air compressor duty cycle can be increased to meet the increased air pressure demand caused by the rough road conditions without triggering false positive alerts or distracting the driver.
