Regulation of a temperature in an exhaust aftertreatment system
A method for the regulation of a temperature in an exhaust stream in a motor vehicle through control of its driveline: the motor vehicle includes a driveline having a combustion engine, which may be connected to a gearbox via a clutch device, and an exhaust system for removing an exhaust stream from the engine. The method includes controlling the driveline for activation or deactivation of coasting of the vehicle based on one or several first parameters P.sub.1 and one or several second parameters P.sub.2 for regulation of a temperature T.sub.Ex in the exhaust system. At least one of the first parameters P.sub.1 is a first temperature difference between the first temperature T.sub.1 in the exhaust system and a reference temperature T.sub.REF. The said second parameter P.sub.2 is related to a calculated speed and/or a calculated road inclination over the road section ahead for the motor vehicle. Further, a computer program, a computer program product, a system and a motor vehicle including such a system are disclosed.
METHODS AND APPARATUS FOR CONNECTED VEHICLES APPLICATION EFFECTIVENESS ESTIMATION
Some embodiments are directed to a processor based computer system for enabling an implementer to select software for deployment to a vehicle control system. The system can include a processor based computer system that is configured to perform a first identifying step that includes identifying available V2X applications for the system, a second evaluation step that includes evaluating parameters for the V2X applications identified in the first identifying step, and a third ranking step that includes raising or lowering the ranking of each V2X application based on the second evaluation step.
Vehicle trailer control
A computer includes a processor and a memory, and the memory stores instructions executable by the processor to, in response to a vehicle towing a trailer being in reverse, determine a relative orientation of the trailer to the vehicle; while the vehicle is in reverse, in response to the relative orientation exceeding a threshold, brake the vehicle; and then, upon receiving an operator input, permit the vehicle to travel in reverse with the relative orientation exceeding the threshold.
Vehicle traveling assist device
Provided is a vehicle traveling assist device capable of suppressing deterioration of ride comfort of an own vehicle due to vehicle traveling assist. A target determination unit calculates a target speed and a target distance based on target vehicle speed information. A plan generation unit generates a distance plan and a speed plan based on the target speed and the target distance through use of a three-stage moving average filter. The three-stage moving average filter is a filter including a first moving average filter, a second moving average filter, and a third moving average filter which are sequentially and serially connected to each other. A vehicle control unit generates an acceleration command for an own vehicle based on the distance plan and the speed plan.
Vehicle velocity control method and device
The disclosure relates to a vehicle velocity control method. The method includes: determining, by an onboard sensor, drivable distances in different directions in front of a current vehicle, and obtaining, at least based on types of targets in the different directions, an area of a drivable space in front of the current vehicle; determining, based on the area of the drivable space and a current vehicle velocity, a result of a safety degree in a current driving scenario; and controlling the vehicle velocity of the current vehicle based on the result of the safety degree. The disclosure further relates to a vehicle control device, a computer storage medium, and a vehicle.
CONTROL DEVICE
In the control device, the identifying unit specifies, as the first vehicle function, a vehicle function having a relatively high use frequency among the vehicle functions assigned to each of the plurality of operation units mounted in the vehicle. The suggesting unit proposes to the user of the vehicle that the identified first vehicle function is assigned to a second operation unit different from the first operation unit to which the first vehicle function is assigned in advance.

Method for controlling line pressure of hybrid vehicle
A method for controlling a line pressure of a hybrid vehicle includes applying, by a controller, a set current corresponding to a target pressure to a first solenoid valve controlling the line pressure, driving, by the controller, a second solenoid valve to open an engine clutch after the applying step, comparing, by the controller, a difference value between a real pressure of the engine clutch sensed by a pressure sensor and the target pressure with a preset pressure after the driving step, and as a result of performing the comparing step, if the difference value is equal to or greater than the preset pressure, controlling, by the controller, an increase of a revolution per minute (RPM) speed of the electric oil pump and an increase of a pressure of the first solenoid valve to be alternately generated.
Selectively controlling a self-driving vehicle's access to a roadway
A processor-implemented method selectively controls a self-driving vehicle's access to a roadway. A vehicle interrogation hardware device receives an autonomous capability signal from an approaching self-driving vehicle. One or more processors compare predefined roadway conditions to current roadway conditions of the access-controlled roadway. In response to the predefined roadway conditions matching the current roadway conditions of the access-controlled roadway within a predetermined range, the processor(s) determine whether the level of autonomous capability of the approaching self-driving vehicle is adequate to safely maneuver the approaching self-driving vehicle through the current roadway conditions of the access-controlled roadway. In response to determining that the level of autonomous capability of the self-driving vehicle is adequate to safely maneuver the approaching self-driving vehicle through the current roadway conditions of the access-controlled roadway, an automatic barricade controlling device positions an automatic barricade to provide the approaching self-driving vehicle with access to the access-controlled roadway.
Feedback control of vehicle aerodynamics
A system is configured to control aerodynamics of a vehicle. The vehicle includes a body having a front end facing oncoming ambient airflow. The system includes a vehicle control device for receiving operator input to command a target vehicle dynamic response. A vehicle subsystem adjusts an actual vehicle dynamic response to the operator input. The system also includes an adjustable aerodynamic-aid element and a mechanism for varying the element's position to control movement of the airflow relative to the vehicle. At least one sensor detects the adjusted actual vehicle dynamic response and communicates a feedback signal indicative of the detected vehicle dynamic response to a controller. The controller also determines a target position for the aerodynamic-aid element using the detected adjusted actual vehicle dynamic response and regulates the aerodynamic-aid element to its target position via the mechanism to control the aerodynamics and achieve the target dynamic response of the vehicle.
