Definitions

• the invention relates to a method for improving a sequence and distance control.
• active cruise control systems which means follow-up and distance control, also known as ACC, AICC or ICC
• ACC follow-up and distance control
• AICC advanced ICC
• Modern high-end vehicles in particular are usually already equipped with a navigation system as an assistance system.
• Conventional cruise control systems also known as “cruise control”
• ACC systems will also increasingly spread in this vehicle class.
• the object of the invention is to increase the comfort and safety of a sequence and distance control.
• sequence and distance regulations or speed regulations with sequence and / or distance regulation functions are called “sequence and distance regulations” or "ACC” for short.
• sequence and distance regulations such as ACC, AICC or ICC, but also includes all subordinate cruise control systems.
• the object is achieved in that in the case of an active sequence and distance control, a possibility or a necessity for a vehicle control to be adopted by a driver of a vehicle is determined in the near future and that the driver is advised that a takeover is imminent or that Attention of the driver is increased when the possibility or necessity of taking over the vehicle control by the driver is recognized.
• the driver is advised as comfortably as possible that the driver will take over in the near future, or his attention will be increased, possibly by a (longer) ACC trip is only available to a limited extent.
• This "gentle" announcement to take over the cruise control gives the driver a comfortable feeling but also a safe feeling when driving the vehicle.
• a driving situation is ascertained or predicted which makes it likely or necessary that the driver will take over the vehicle control or that the driver will pay more attention in the near future.
• data or signals from a vehicle navigation system are also taken into account to determine the possibility or necessity of the driver taking over the vehicle control.
• a vehicle navigation system and the sequence and distance control are networked.
• a speed specified by the driver is not used as a guide variable for the engine and / or braking torque request when a change of direction (turning process) is imminent, which requires the driver's attention.
• a special control mode is initiated which reduces the speed by slowly reducing the engine torque.
• an automatic braking is carried out, which preferably does not exceed a value of approximately -0.1g.
• an automatic braking is carried out, which brakes the vehicle to a speed assigned to the current route, such as a motorway or country road, and / or produces a noticeable reduction in the vehicle speed for the driver ,
• a possibility or necessity is determined a takeover "a vehicle control by a driver of a vehicle in the next time when the possibility or The need for a takeover is imminent within the next 15 seconds (sec.) To 140 seconds.
• a vehicle has a navigation system, an ACC system and means that make it possible to recognize or predict a situation that requires increased attention from the driver. Means are also provided by means of which the driver can be comfortably informed of such a situation. To make this possible, the navigation system and ACC are networked with one another according to the invention.
• a high-quality navigation system is used that uses a large-area display. This display is controlled via an existing CAN connection in the vehicle.
• the instructions for changes of direction are also shown and are therefore also available on the CAN (or a separate data transmission).
• the representation of the change of direction is also modeled on the real course of the road and includes therefore also an appropriate angle information.
• This angle information does not have to correspond exactly to the course of the road, but "only w contain trend information such as” sharp "turning or only” slight "change of direction.
• this information is provided individually or in combination to the ACC system or generally to a cruise control system.
• this information can also be supplied to an electronic brake control system, in particular a vehicle dynamics controller (ESP).
• ESP vehicle dynamics controller
• the speed specified by the driver is not used as a guide variable for the engine and / or braking torque request, but a special control mode is initiated. Then the speed is advantageously reduced by slow engine torque reduction.
• the term “change of direction” is understood to mean leaving the road currently being driven, not a cornering of the normal course of the road.
• a particularly typical example here is the approach of the vehicle to a motorway exit. Highway driving are also preferred for active ACC control.
• an automatic speed adjustment to the entire course of the road is not generated, but the driver's attention is only increased if a turning maneuver impending from the information of the navigation system is foreseeable after longer ACC journeys.
• moderate braking can also be carried out by the ACC system according to the invention.
• This "moderate" automatic braking process should not exceed vehicle deceleration in a comfort range, which means a deceleration of preferably approximately -0.1 g.
• the speed can be reduced to a speed assigned to the route as standard, such as 100 km / h on motorways, or generate a noticeable difference (e.g. 20 km / h) from the speed set by the driver.
• This special control mode deviates from the homogeneous speed control and, according to the invention, attracts the driver's attention and thus makes a contribution to driving safety.
• the navigation system can also output a voice to increase the driver's attention.
• the special control module can also be initiated before the turning process is shown on the display if the corresponding information (distance to the turning point) is available.
• the driver does not see this information as a malfunction or paternalism, because the special control mode simulates the driving style of a forward-looking driver that increases comfort and is plausible. Because usually in connection with a significant change in direction, the vehicle speed is reduced accordingly.
• the special control mode is thus integrated into the "normal" driving style and does not have a disruptive effect because the driver would have initiated the same driving maneuver by switching off the ACC system (if necessary by briefly applying the brakes).
