A vehicular breaking force control system that includes a control device including a processor that acquires a plurality of longitudinal accelerations from a driving assistance system, and calculates a driving/braking request when the vehicle is in a coasting state in which an acceleration operation or a deceleration operation are not performed during running of the vehicle. The processor further acquires a driving force lower limit set for a powertrain actuator having a set gear ratio, and distributes the driving/braking request to at least one of (i) a powertrain system including the powertrain actuator and (ii) a brake system including a brake actuator. The driving/braking request is distributed to the at least one of the powertrain system and the brake system based on the acquired driving force lower limit.

A system includes a processor and a memory storing instructions executable by the processor to select a distance based on a determination of whether a lane adjacent a primary vehicle and a secondary vehicle in front of the primary vehicle is clear. The instructions include instructions to actuate a braking system of the primary vehicle when the primary vehicle is at the distance from the secondary vehicle.

A control system of a vehicle includes: a target speed module configured to, using a parametric driver model and based on first driver parameters, second driver parameters, and vehicle parameters, determine a target vehicle speed trajectory for a future predetermined period; a driver parameters module configured to determine the first driver parameters based on conditions within a predetermined distance in front of the vehicle; and a control module configured to adjust at least one actuator of the vehicle based on the target vehicle speed trajectory and a present vehicle speed.

A driving assist device includes a first sensor, a second sensor, and a control device. The control device does not execute an inter-vehicle distance control under a predetermined first condition upon determination that at least one preceding object is detected based on the output of one of the first sensor and the second sensor without being detected based on the output of the other of the first and second sensors; and an environment of a non-detection sensor that is the other of the first and second sensors satisfies a first requirement for determination of a reliability of the output of the non-detection sensor; and the control device executes the inter-vehicle distance control under a predetermined second condition upon determination that the environment of the non-detection sensor satisfies a second requirement for determination of the reliability of the output of the non-detection sensor.

This driving assistance device includes a target acceleration correcting unit configured as follows: if there was input, from a coupling detection unit, of detection results indicating that a trailer has been coupled, the target acceleration correcting unit outputs a target acceleration, output from an ACC unit, as-is to a drive system; and if there was input of detection results indicating that a trailer (2) has not been coupled, the target acceleration correcting unit corrects to a smaller value the target acceleration, output from the ACC unit, and outputs said corrected target acceleration to the drive system.

There is provided an adaptive cruise control method for autonomously adapting the speed of an ego vehicle (300) to maintain a target headway, headway being distance from the ego vehicle to a forward vehicle (302), the ego vehicle equipped with a perception system (100) for measuring a current headway and a current speed and acceleration of the forward vehicle relative to ego vehicle, the method comprising: in response to detecting that the current headway is below the target headway, determining and implementing a deceleration strategy for increasing to the target headway; wherein the deceleration strategy is determined so as to selectively optimize for comfort in dependence on a predicted headway, the predicted headway computed for a future time instant based on the current speed and acceleration of the forward vehicle relative to the ego vehicle.

Provided is a driver assistance system (DAS) including: a storage configured to store driver tendency data including an amount of decrease in acceleration when a vehicle approaches a specific section, in a state in which an adaptive cruise control (ACC) of the vehicle is deactivated; and a controller including at least one processor configured to process the driver tendency data, wherein the controller is configured to, upon the vehicle re-entering the specific section during travel of the vehicle with the ACC, control the vehicle to perform one of acceleration control and deceleration control based on the driver tendency data.

An embodiment inter-platooning vehicle distance controller includes a processor configured to separate a linear control section from a non-linear control section based on whether a preceding vehicle brakes during platooning, predict a real-time deceleration for each platooning vehicle with regard to a disturbance factor when generating a deceleration in the linear control section, and set target decelerations of platooning vehicles based on the predicted real-time deceleration, and a memory configured to store data and an algorithm executable by the processor.

A non-transitory computer readable storage medium has instructions executed by a processor to obtain the relative speed between a first traffic object and a second traffic object. The separation distance between the first traffic object and the second traffic object is received. The relative speed and the separation distance are combined to form a quantitative measure of hazard encountered by the first traffic object. The obtain, receive and combine operations are repeated to form cumulative measures of hazard associated with the first traffic object. The cumulative measures of hazard are analyzed to derive a first traffic object safety score for the first traffic object.

A method for the automatic control of the longitudinal dynamics of a vehicle is provided by which vehicles traveling ahead are detected. If an upcoming traffic jam is detected, the vehicle is decelerated until a predefined distance behind the tail end of the traffic jam is reached. When the predefined distance from the traffic jam tail end has been reached, the vehicle automatically controlled in its longitudinal dynamics is able to close the remaining, predefined distance to the traffic jam tail end at a low differential velocity in comparison to the velocity of the traffic jam tail end. Using an additional rear sensor system that senses trailing vehicles, the controlled vehicle is made to close the distance to the traffic jam tail end only if a trailing vehicle was detected.
