A method for controlling a subject vehicle with a braking system, a drive system and a distance control system, wherein the distance control system is configured to control an actual following distance between the subject vehicle and a vehicle ahead to a predetermined target following distance, wherein the target following distance is predetermined as a function of an activated operating mode of the distance control system, including performing a plausibility check by checking whether V2X data is exchanged or can be exchanged between the vehicle ahead and the subject vehicle over a V2X connection, and activating, if no V2X data is exchanged or can be exchanged between the vehicle ahead and the subject vehicle over the V2X connection, a first operating mode in which a first target following distance is predetermined as a function of a reaction time of a driver of the subject vehicle.

A cruise operation fuel efficiency improvement control method, the method may include detecting, by an engine control unit, a cruise Resume request during a coasting running state of a vehicle; controlling a NCC Cruise Control which performs a cruise torque control of the vehicle after performing a control of an Electronic Stability Control (ESC) which sets a vehicle speed to a cruise target speed followed by a control of a transmission control unit, when the coasting running is recognized as a Neutral Control Coasting (NCC); and controlling a SSC Cruise Control which performs the cruise torque control of the vehicle after performing the control of the Electronic Stability Control (ESC) which sets the vehicle speed to the cruise target speed followed by the control of the transmission control unit in a driving state of an engine, when the coasting running is recognized as a Start Stop Control (SSC).

Provided are a travel control device, a vehicle, and a travel control method that ensure safety in cases of a possible lane departure. This travel control device is equipped with: a travel control unit that switches between and executes a constant speed travel control for causing a vehicle 1 to travel at a target speed and a coasting control for causing the vehicle to travel by inertia; and a switching control unit that, in cases in which it has been determined by a lane departure warning unit that there is a risk that the vehicle will depart from the travel lane while executing the constant speed travel control or the coasting control, controls the travel control unit to execute the constant speed travel control without executing the coasting control for a prescribed period of time.

A cruise operation fuel efficiency improvement control method, the method may include detecting, by an engine control unit, a cruise Resume request during a coasting running state of a vehicle; controlling a NCC Cruise Control which performs a cruise toque control of the vehicle after performing a control of an Electronic Stability Control (ESC) which sets a vehicle speed to a cruise target speed followed by a control of a transmission control unit, when the coasting running is a Neutral Control Coasting (NCC); and controlling a SSC Cruise Control which performs the cruise toque control of the vehicle after performing the control of the Electronic Stability Control (ESC) when the coasting running is a Start Stop Control (SSC).

An autonomous vehicle with adaptable cruise control in which a virtual vehicle object is generated to pace the autonomous vehicle for a smooth acceleration when transitioning between an ACC mode and a CC mode. An acceleration profile sets a virtual vehicle object acceleration as a function of a speed difference between the current road speed limit and the current autonomous vehicle speed, and the current autonomous vehicle acceleration. The perception data may be generated for the virtual vehicle object to simulate the existence of the virtual vehicle object on the road traveled by the autonomous vehicle. The generated perception data and acceleration data are provided to an ACC module to control the acceleration of the autonomous vehicle. The acceleration profile of the virtual vehicle object is tunable.

In accordance with an aspect of the present disclosure, cruise control of an automotive vehicle in a fuel economy cruise control mode controls vehicle speed to be within a fuel economy speed band about a cruise control set speed so that instantaneous fuel economy is at least equal to average fuel economy.

A user interface device for an autonomous vehicle (AV) can include an autonomy engage selector and a plurality of vehicle interfaces connected in series. Each of the plurality of vehicle interfaces can correspond to a respective vehicle operation and can include a relay that engages when the vehicle interface is in a ready state. The user interface device can also include a drive-by-wire controller to autonomously operate each of the plurality of vehicle interfaces in response to an engage input on the autonomy engage selector when the user interface device is in a ready condition.

An approach to setting a cruise control speed based on identifying a vehicle operator and analyzing metadata associated with the vehicle operator. The identity of the vehicle operator and any passengers is determined based on identity sensors in the vehicle or by manual identity entry. Metadata, associated with the vehicle operator, is retrieved from the metadata database, located either locally or remotely. The metadata is analyzed based on factors such as the current route and the identity of any passengers. The cruise control speed is set based on the results of the analysis. Any changes to the setting are updated in the metadata database.

An adaptive cruise control system for a vehicle may include an access device configured to receive manual input and responsively generate control signals for use in controlling acceleration, braking and steering of a vehicle. The adaptive cruise control system may also include at least one additional device located remote from the access device and configured to receive manual input and responsively generate control signals for use in controlling acceleration, braking and steering of the vehicle. The adaptive cruise control system may further include a controller in communication with the access device and the at least one additional device. The controller may be configured to control acceleration, braking and steering of the vehicle based on the manual input received via the access device and the at least one additional device.
