  • 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.

  • Publication number: 20190270437
    Abstract: When a vehicle experiences an instability event, an instability event trigger (e.g., a failed modulator, unexpected yaw or lateral acceleration, unexpected steering wheel position change, etc.) is monitored and the magnitude thereof is compared to a corresponding predetermined threshold above which corrective action is initiated. Depending on the magnitude and type of instability trigger, one or more wheel ends are identified as candidates for brake activation. Braking force at the identified wheel ends is gradually increased until the vehicle becomes stable or comes to a stop.

  • Patent number: 10372123
    Abstract: Platoon management control systems and methods rearrange three of more vehicles cooperatively travelling seriatim as a platoon along an associated roadway into a platoon arrangement other than the linear or single file formation. Multi roadway lane platoon management control systems and methods control the three or more vehicles cooperatively travelling as a multi-lane platoon along an associated multi-lane roadway into a platoon arrangement other than the linear or single file formation. Larger platoon sizes are provided thereby enabling more vehicles to participate in the larger multi-lane platoon. A platoon management control uses a combination of the GPS position of the lead vehicle representative of the position of the vehicle relative to the associated geographical area, and braking performance data representative of the braking capabilities of following vehicles to rearrange the vehicles into the non-columnar formation.

  • Patent number: 10363923
    Abstract: A system and method are provided for hybrid electric internal combustion engine applications in which a motor-generator, a narrow switchable coupling and a torque transfer unit therebetween are arranged and positioned in the constrained environment at the front of an engine in applications such as commercial vehicles, off-road vehicles and stationary engine installations. The motor-generator is preferably positioned laterally offset from the switchable coupling, which is co-axially-arranged with the front end of the engine crankshaft. The switchable coupling is an integrated unit in which a crankshaft vibration damper, an engine accessory drive pulley and a disengageable clutch overlap such that the axial depth of the clutch-pulley-damper unit is nearly the same as a conventional belt drive pulley and engine damper. The front end motor-generator system includes an electrical energy store that receives electrical energy generated by the motor-generator when the coupling is engaged.

  • Patent number: 10343658
    Abstract: An apparatus and method are provided for determining the braking status of trailers and dollies in a multi-trailer vehicle train. A vehicle controller receives inputs from the vehicle to determine an estimate of the total vehicle mass from the dynamic response of the vehicle to an input such as application of engine torque, and to determine an estimate of the loads of the vehicle based on information provided from trailers and dollies communicating with the vehicle controller. A plausibility analysis is conducted to determine whether the estimates are within a tolerance range indicative of whether all of the trailers and dollies are communicating with the vehicle controller. If the vehicle controller determines that not all of the trailer and dolly anti-lock braking and/or stability control systems are available, the vehicle controller may in subsequent braking events command trailer and dolly brake application at a reduced level intended to avoid trailer and dolly wheel skidding.

  • 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.

  • Patent number: 10272890
    Abstract: When a brake system on a commercial vehicle, lateral acceleration and/or yaw of the vehicle are monitored and compared to a first predetermined threshold. If the first predetermined threshold is exceeded, a precharge command is sent to the brake system to precharge one or more air chambers by temporarily deactivating a modulator valve and activating an antilock traction relay valve in order to charge the air chambers up to a level permitted by the modulator valve. Upon detecting a panic braking event, a command signal is sent to the brake system to release the precharged air to facilitate braking.
