Abstract: Inter-vehicle platoon distance management is provided. Parameters relating to external conditions are used together with vehicle physical characteristics, performance information, and other factors to select an optimized distance between vehicle pairs traveling as a platoon. The parameters relating to the external conditions are aggregated by the following vehicle of the platoon vehicle pair, and used to adjust or otherwise modify a predetermined minimum following distance parameter. This allows flexibility in the platooning control to follow at different distances while maintaining an overall fuel economy benefit of the platoon. When no external condition restrictions exist, the platoon vehicles follow at the shortest distance to maximize fuel economy. However, as the aggregated external conditions increase, the platooning distance is extended to improve safety while preserving as much fuel economy benefit of the platoon as possible.

Abstract: A controller is configured to receive a signal representing a requested system brake application and an identified urgency. A hardware processor is capable of: determining a maximum braking pressure to be applied during the system braking application based on the identified urgency; generating a first system brake mode control signal, based on the determined maximum braking pressure, to set an associated first valve to a first valve state; generating a second system brake mode control signal, based on the determined maximum braking pressure, to set an associated second valve to a second valve state, the maximum braking pressure during the system braking application being set by the first valve state and the second valve state; determining an activation profile based on the determined maximum braking pressure; the controller transmitting the first and second system brake mode control signals and modulator control signals according to the activation profile.

Abstract: A controller (22) for identifying an over-speed condition of a vehicle (10) is adapted to identify a current posted speed limit; determine whether to identify an over-speed condition of the vehicle (10) based on the current posted speed limit, a previous posted speed limit and a current speed of the vehicle (10); and if it is determined to identify the over-speed condition, transmit an over-speed warning signal to activate a warning device (24).

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. A controller deceleration command input receives a deceleration command signal which is compared against predetermined threshold deceleration rate value or against a current deceleration value being executed by the combination vehicle and, based on a result of the comparisons, either the enhanced or the non-enhanced braking modes are implemented by the controller.

Abstract: Vehicle brake performance monitoring is provided. Braking capabilities are dynamically 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. Desired gaps between the platooning vehicles may be modified in accordance with the learned or otherwise calculated or determined relative braking capabilities as necessary or desired. During every vehicle stop, the vehicle and axle loads together with information on the time from brake apply to when the vehicle decelerates is monitored and entered as a data point defining the vehicle response delay. The axle loads and the ABS Activation of a wheel end for a given pressure is further selectively used to create another data point. The data points are selectively used to develop overall performance (e.g., quality score) of the brake system.

Abstract: A braking controller (22) 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. A needed deceleration is compared with a threshold corresponding to the non- enhanced braking mode. Alternatively, a needed deceleration is used to determine a needed (momentary) distance, which distance is compared with a detected distance. The braking mode is in all cases determined on the basis of the mentioned comparisons.

Abstract: Systems and methods are provided for platoon initialization, redundant lane departure control, and redundant communication operation. A platooning initiation strategy requires continuous communication between vehicles for a more than a predefined duration, a demonstration of an operable brake light on the leading vehicle, and command control profile compatibility between the vehicles before allowing the vehicles to mutually platoon or to join an existing platoon. A set of computer readable labels visible to a Lane Departure System placed on a lead vehicle are used by a following vehicle when lane markings become invisible to sensors. A redundant brake lamp operable in a non-visible spectrum is provided for platooning. A specific brake lamp for use exclusively for platooning purposes may be provided.

Abstract: A platoon management control uses the GPS position of the rear of a lead vehicle. The lead vehicle deceleration demand is overlaid upon the position of the rear of the lead vehicle. The following vehicle uses its own GPS position along with the radar or vision system of the following vehicle to determine the rear of the lead vehicle. When a lead vehicle's deceleration signal is subtracted from the position of the rear of the forward vehicle as determined by the following vehicle, the deceleration profile must be within an acceptable window to be valid. Also, one or more local sensors on adjacent platooning vehicles are used to communicate encoding scheme selection information and also to communicate the deceleration command signals. This permits the following vehicle to decode the deceleration command signals using a decoding scheme corresponding to the encoding scheme indicated as being used by the leading vehicle.

Abstract: A controller for a driver assistance system on a host vehicle comprises an input for receiving a video signal; an input for receiving a signal indicative of an obstacle; an alert output for transmitting an alert; and control logic. The control logic is capable of identifying a lane marker in the video signal; setting a first zone with respect to the lane marker; receiving a signal indicative of an obstacle; setting a second zone with respect to the lane marker in response to the obstacle; and transmitting an alert at the alert output in response to the host vehicle entering the second zone.
