An adaptive cruise control for a motor vehicle includes a detection module for detecting a vehicle ahead, a production module capable of producing a setpoint, a storage module configured to store a value corresponding to the setpoint, a chronometer configured to be initialized and activated at a moment when the vehicle stops, and a reinitialization module for reinitializing the storage module. This cruise control includes a setup module capable of determining a limit according to the environment of the vehicle. The reinitialization module reinitializes the value stored by the storage module if the chronometer provides a duration greater than the limit.

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.

Vehicles may have the capability to navigate according to various levels of autonomous capabilities, the vehicle having a different set of autonomous competencies at each level. In certain situations, the vehicle may shift from one level of autonomous capability to another. The shift may require more or less driving responsibility from a human operator. Sensors inside the vehicle collect human operator parameters to determine an alertness level of the human operator. An alertness level is determined based on the human operator parameters and other data including historical data or human operator-specific data. Notifications are presented to the user based on the determined alertness level that are more or less intrusive based on the alertness level of the human operator and on the urgency of an impending change to autonomous capabilities. Notifications may be tailored to specific human operators based on human operator preference and historical performance.

A method for the automated control of the longitudinal movement of a motor vehicle having an automated positive acceleration process in a longitudinal direction of the vehicle and an automated deceleration in the longitudinal direction of the vehicle. An acceleration variable is determined based on a jerk value and limited in terms of absolute value. And the jerk value is in turn determined in a driving mode in which, starting from a vehicle actual longitudinal speed and a vehicle actual longitudinal acceleration, the motor vehicle is adjusted to a predeterminable vehicle longitudinal speed taking into account a predeterminable maximum positive driving mode vehicle longitudinal acceleration, a predeterminable maximum driving mode vehicle longitudinal deceleration and at least one predeterminable driving operating mode jerk absolute value which limits the jerk.

The disclosure generally pertains to systems and methods for assisting a driver to travel through a drive-through lane of an establishment in an autonomous mode of operation. In an example method, a processor in a vehicle determines a location of the vehicle in a drive-through lane in various ways such as, for example, based on objects located in the vicinity of the drive-through lane, based on location coordinates, and/or based on a geofence defined around the establishment. The processor may then place the vehicle in an autonomous mode of operation and instruct the driver of the vehicle to refrain from touching vehicle driving control components such as the steering wheel, the brake pedal, and the accelerator pedal. The vehicle autonomously then moves through the drive-through lane in a stop-and-go mode of movement at a controlled speed while executing lane-centering and collision avoidance.

A driving assistance system for a vehicle, comprising: a detection unit configured to detect information regarding surroundings of the vehicle; and a control unit configured to perform driving assistance control based on information detected by the detection unit, wherein, when the control unit performs an operation of stopping movement due to an object detected by the detection unit during the driving assistance control, the control unit restarts the movement after a predetermined time elapses from when the stop operation is started.

Provided are a device for warning of the distance between vehicles and a control method for warning of the distance between vehicles which can further give a sense of security to an occupant. The device for warning of the distance between vehicles comprises: a preceding vehicle specifying unit which specifies a preceding vehicle that travels in front of a vehicle; and a warning output control unit which, when the preceding vehicle is in a stationary state, outputs a warning of the distance between the vehicles from a warning output unit on the condition that the vehicle is executing adaptive cruise control (ACC).
