A vehicle includes a motor and a controller. The controller is programmed to, responsive to an autonomous braking request and a predicted average braking torque associated with the request having a magnitude less than a powertrain regenerative torque limit, brake the vehicle only with the motor according to a torque profile adapted from a most efficient torque profile of the motor so as to have an average value falling within a specified range of the average braking torque.

Systems and methods for managing platooning vehicles are described herein. In one aspect, a first vehicle may transmit information to a second vehicle indicating one or more conditions, such as an amount of brake applied at the first vehicle. Based on the condition received at a controller in the second vehicle, the controller in the second vehicle may adjust how it operates. For example, the controller in the second vehicle may adjust how much emphasis it places on one type of input as opposed to another.

A driving assistance apparatus can provide deceleration assistance of decelerating a host vehicle independently of an operation by a driver. The driving assistance apparatus is provided with: a specifier configured to specify a type of a target associated with the deceleration assistance, wherein the target is ahead of the host vehicle on a course thereof and requires the host vehicle to decelerate or stop; and a controller programmed to change an end condition associated with deceleration assistance, in accordance with the specified type.

A driving assistance device (30) that has: an information acquisition unit (31) that acquires the relative speed of a vehicle ahead and the inter-vehicle distance to the vehicle ahead; a table (33) in which degrees of urgency that correspond to relative speeds and inter-vehicle distances have been pre-stored; and an ACC control unit (32) that reads out, from the table (33), a degree of urgency (x) that corresponds to the relative speed and inter-vehicle distance acquired by the information acquisition unit (31), finds a target acceleration/deceleration that has a slope (y) that is based on the degree of urgency (x) that was read out, and outputs the found target acceleration/deceleration as a control signal for controlling break pressure.

A method for adaptively controlling a vehicle speed in a vehicle includes establishing a reference speed; and activating an engine and/or brakes and/or a transmission of the vehicle by a speed-control system as a function of a set vehicle speed and/or a set vehicle retardation for fuel-saving adaptation of the currently existing vehicle speed to the reference speed. The set vehicle speed and/or the set vehicle retardation for a current driving-dynamics situation of the vehicle defined by driving-dynamics vehicle parameters is/are determined as a function of at least one computation coefficient. The at least one computation coefficient is provided by an external arithmetic unit outside the vehicle as a function of the currently existing driving-dynamics vehicle parameters and also as a function of currently existing route information for a route segment situated ahead. The route segment situated ahead is established on the basis of the currently existing driving-dynamics vehicle parameters.

A method for compensating for excessively low actuating dynamics of a mechanical brake of a transportation vehicle, wherein a dividing unit receives a predefinition for a target overall retardation of the transportation vehicle and determines a mechanical target braking torque based on the target overall retardation and signals the same to the mechanical brake. The dividing unit predicts a mechanical actual braking torque of the brake by a model of the brake actuator and, based on the predicted mechanical actual braking torque, by activating at least one predetermined transportation vehicle component that is different from the mechanical brake, to generate a compensation torque, by which a control deviation which results when adjusting the mechanical actual braking torque to the mechanical target braking torque is compensated and the target overall retardation results in the transportation vehicle.

Systems and methods for increasing the safety of vehicle platooning systems are described. In one aspect, a determination is made as to how many trailers are connected to a tractor, and whether those trailers and any dollies are equipped with an Anti-Lock Braking System. For example, multiple processes for determining whether an Anti-Lock Braking System is operating correctly may be employed to prevent false positives and false negatives. Such processes may determine rates of messages received from Anti-Lock Braking System units, types of messages received from Anti-Lock Braking System units, and/or amounts of types of messages received from Anti-Lock Braking System units.

Aspects concern a method for controlling a braking of a vehicle. The method including detecting a braking situation, determining a classification of the braking situation, selecting a braking profile based on the determined classification, and applying a deceleration based on the selected braking profile to maintain a safety distance based on the selected braking profile.

Systems and methods for increasing the safely platooning are described. In one aspect, safely platooning includes verifying that a vehicle is not decelerating less than necessary, verifying that the vehicle is not accelerating unintendedly, verifying that the vehicle is not decelerating unintendedly, verifying that the vehicle is not platooning unintendedly, verifying that notifications provided by a platooning electronic control unit are being transmitted to their intended destinations, verifying that information received from a network operations center is correct, and verifying that the instability of the vehicle does not exceed a threshold amount.

The invention involves a low speed control system and method for automatically regulating the speed of work vehicles or equipment and, more particularly, vehicles that apply, remove or modify roadways or road markings. The system includes a controller, a speed display, at least one rotary encoder or the like, and one or more Eddy current or mechanical brakes for inhibiting motion of the vehicle at the operator's control. The brakes may be pneumatic, spring operated, Eddy current, or hydraulic that are controlled in response to feedback from the at least one rotary encoder for compliance with the preset speed on the speed display. In another embodiment, a throttle control is also provided.
