Method for operating a longitudinal driver assistance system (13) of a motor vehicle (12) which is designed to regulate the speed of the motor vehicle (12) to a control speed, whereindepending on environment data describing the operating environment in which the motor vehicle (12) is currently operatedthe control speed can be changed from a desired speed (3) provided by a driver to a target speed (5) (which is provided for an upcoming operating environment (2) and/or can be determined from the environment data), wherein, when there is a change of the desired speed (3) to a new target speed (5) for an upcoming operating environment (2), for a predetermined time period and/or a predetermined distance in the upcoming operating environment (2), an intermediate speed (6) deviating from the target speed (5) in the direction of the current speed of the motor vehicle (12) is initially regulated to, which intermediate speed (6) is between the current speed of the motor vehicle (12) and the target speed (5), before the target speed (5) is regulated to after the time period expires or before the distance is traversed.

A vehicular driver assist system includes a forward-viewing camera disposed at and viewing through a windshield of a vehicle. The vehicular driver assist system sets an initial vehicle soft lock speed when speed of the vehicle reaches an initial threshold speed of travel. With the initial vehicle soft lock speed set and with the vehicle speed exceeding the initial vehicle soft lock speed, the system maintains the vehicle speed at the initial vehicle soft lock speed when the vehicle speed reduces to the initial vehicle soft lock speed by coasting. When speed of the vehicle increases by a multiple of a vehicle speed increment above the initial vehicle soft lock speed, the system sets an increased vehicle soft lock speed and maintains the vehicle speed at the increased vehicle soft lock speed when the vehicle speed reduces to the increased vehicle soft lock speed by coasting.

Systems and methods for adaptive cruise control based on user defined parameters are disclosed. An example disclosed vehicle includes a GPS receiver configured to provide a location of the vehicle, an adaptive cruise control; and a cruise control adjuster. In the example cruise control adjuster is configured to generate an action when a cruise control event is defined for the location. In the disclosed example the cruise control event is based on past changes to the adaptive cruise control at the location. The example cruise control adjuster is also configured to apply the action to the adaptive cruise control to change how the adaptive cruise control controls the vehicle.

A vehicle control device which can substantially eliminate or shorten a period when vehicle speed exceeds a lowered speed limit when a vehicle goes into a road where a speed limit lower than before then during running of the vehicle should be provided. A speed control decreases vehicle speed so that the vehicle speed approaches the next speed limit from a time point when it is judged that a position of the own-vehicle is at a predetermined position in front of a transition point which is a point where the next speed limit starts to be applied, in a case where a specified condition that the next speed limit is lower than the present speed limit is satisfied.

Some embodiments of the present invention provide a system comprising: a first, controller operable to assume an off state or one of one or more on states, in a first on state the first controller being configured to generate a first controller powertrain signal in order to cause a powertrain to develop drive torque and cause a vehicle to operate in accordance with a target speed value, the system being configured to cause the first controller to assume the first on state in dependence at least in part on receipt of a first input signal indicative that the controller is required to assume the first on state and a second signal indicative that a driver is maintaining a driver-operated brake control device in a brake-applied condition, being a condition in which a braking system of a vehicle is caused to apply a brake to one or more wheels.

A longitudinally guiding driver assistance system in a motor vehicle includes a detection system for detecting currently applying events and relevant events lying ahead, which require an adaptation of the permissible maximum speed, and a function unit which, when detecting a relevant event, while taking into account the location of the relevant event lying ahead, determines a location-dependent point in time, whose reaching causes the function unit to initiate an output of prompt information for permitting an automatic adaptation of the currently permissible maximum speed to a new permissible maximum speed. The function unit is designed, in the case of an activation of the longitudinally guiding driver assistance system, while taking into account a detected currently applying event, to initiate a first output of prompt information for permitting an automatic first setting of the currently applying permissible maximum speed as the new permissible maximum speed.

A controller that controls operation of the motorcycle, to which a surrounding environment detector is mounted, includes: an acquisition section that acquires information on the surrounding environment of the motorcycle on the basis of output of the surrounding environment detector during travel of the motorcycle; and an adaptive cruise operation performing section that makes the motorcycle perform adaptive cruise operation on the basis of the surrounding environment information acquired by the acquisition section. The acquisition section acquires other vehicle travel state information that is information on a travel state of an other vehicle acquired by a different vehicle from the motorcycle via wireless communication. The controller further includes a safety operation performing section that makes the motorcycle currently performing the adaptive cruise operation perform safety operation on the basis of the other vehicle travel state information acquired by the acquisition section.

Aspects of the present invention relate to a speed control system (15) for a vehicle (10), to a method and to a vehicle (10). The system causes the vehicle (10) to drive at a target speed value. The speed control system (15) uses a pitch rate signal indicative of a rate of change of pitch of a vehicle (10) and a driving surface gradient signal indicative of a gradient of a driving surface upon which the vehicle (10) is being driven to determine if the vehicle is cresting. The determination that cresting is occurring depends on the rate of change of pitch exceeding a predetermined value; and the gradient value of the driving surface being below a predetermined value. The speed control system (15) outputs a speed reduction signal to reduce the speed of the vehicle when the vehicle is cresting.

The present disclosure relates to a computer implemented method for operating an autonomous vehicle based on sensor data representative of an area in a driving direction of and in the vicinity of the vehicle. The vehicle is equipped with a control unit adapted to determine if a plurality of detailed actions to be performed by the vehicle successfully may be used for fulfilling a desired general action plan for the vehicle. The present disclosure also relates to a corresponding control system and to a computer program product.

Aspects of the present invention relate to a speed control system (15) for a vehicle (10), to a method and to a vehicle (10). The system causes the vehicle (10) to drive at a target speed value. The speed control system (15) receives a turn indicator status signal indicative of a state of a turn signal indicator control of the vehicle. The system (15) determines a turn indicator target speed limit in dependence on the turn indicator status signal and controls the vehicle in accordance with the turn indicator target speed limit.
