摘要:
Methods and apparatus for storing, accessing, generating and using information about speed limits and speed traps are described. The system includes a positional sensor such as a GPS device. Position information is used to access a database of speed limit and/or speed trap information. The database may be local or remote. Access to a remote database may be achieved using a wireless communications device such as a wireless (cellular) modem. Encountered speed traps are logged in response to the activation of a speed trap alert button by a user of the device or the output of a radar/laser detector. Speed trap position, date and time information is transmitted to the remote database system. Speed limit information is used to control the speed of the automobile as part of a cruise control operation and/or is used to provide the motor vehicle operator with warnings, e.g., that the applicable speed limit is being exceeded. Speed trap information which is retrieved using positional information provided by the GPS device is used to warn the user of the device of speed traps in the user's vicinity as the user approaches the location of the known speed trap.
摘要:
A system and method for controlling overtaking by a vehicle equipped with a distance/speed control device traveling a multi-lane roadway of one or more vehicles traveling ahead. The controlled vehicle tracks a vehicle ahead, ascertains the lane in which the vehicle ahead is traveling and, on the basis of the lane and speed and/or distance of the vehicle ahead relative to the controlled vehicle, the speed of the controlled vehicle is adjusted to permit overtaking in the passing lane if the vehicle ahead is traveling in a non-passing lane, and overtaking in a non-passing lane is not permitted if the vehicle ahead is traveling in a passing lane. If a line of vehicles traveling ahead is recognized, overtaking in the non-passing lane is permitted, depending on location-specific traffic rules, the speed of the controlled vehicle being adjusted as appropriate to overtake the line of vehicles.
摘要:
A method for the longitudinal control of a vehicle, in which information of a navigation system is detected and in which, as a function of the information of the navigation system, a desired value of at least one parameter for the longitudinal control is defined, during a longitudinal control operation, on the basis of a defined desired distance from a preceding vehicle by means of information of the navigation system. The probability is determined with which the preceding vehicle and/or the own vehicle is cornering when the preceding vehicle is no longer detected. A longitudinal acceleration takes place in a time-delayed manner when the probability is greater than a defined threshold.
摘要:
A method for operating a control device of a motor vehicle driving by automation. The method includes determining a location of the motor vehicle, and acquiring driving-environment data of the motor vehicle, a control characteristic of the control device of the motor vehicle being formed in such a way that a driving behavior of at least one other road user is influenced in defined manner.

Generally described, aspects of the disclosed subject matter are directed to managing the configuration of a vehicle. In accordance with one embodiment, a method of modifying the configuration of a vehicle based on the vehicle's location is provided. The method includes receiving, from a remote Satellite Positioning System (“SPS”) device, positioning data that identifies the location of the vehicle. Then, the positioning data is used to identify one or more regulations that are applicable, given the location of the vehicle. Based on collected vehicle readings, a determination is made regarding whether the configuration of the vehicle should be modified. In turn, the method may cause the configuration of the vehicle to be modified to comply with the one or more regulations.

For substantial relieving the driver of a vehicle with respect to the monitoring of the preceding environment as well as the evaluation of distances and speeds of multiple preceding vehicles, there is provided in accordance with the invention a process for detecting and monitoring a number of vehicles (A through C) preceding one's own vehicle (E), which process divides the preceding environment into at least a near zone (ZII) and at least one distant zone (ZI), wherein for the preceding vehicles (A through C) respectively their lane (S1 through S3), speed (VA through VC) and/or distance to the monitoring vehicle (E) are determined, and on the basis of the respective determined lane (S1 through S3), speed (VA through VC) and/or distance for the preceding vehicles (A through C) their position with respect to the near zone (ZII) or the distant zone (ZI) are determined, wherein on the basis of the respective determined speeds (VA through VC) and/or positions of the preceding vehicles (A through C) the actual speed (VE actual) of the monitoring vehicle (E) is adjusted.

A system for controlling a vehicle drivetrain in a fuel-efficient manner includes, in one embodiment, a control computer operable to determine a number of engine load/engine speed boundary conditions as functions of brake specific fuel consumption (BSFC) contours in relation to an engine output characteristics map and define therefrom an undesirable engine operation region U. As long as the engine is engaged with at least one of the gear ratios of the vehicle transmission, the control computer is operable to maintain or encourage engine operation outside of the region U. In another embodiment, the control computer is operable to define a contour from substantially zero engine load to substantially full engine load, wherein the contour preferably corresponds to a fuel-efficient path from no-load to full-load engine operating conditions. With change gear transmissions, the control computer is operable to control transmission shift points about the contour. With continuous variable transmissions, the control computer is operable to modify the effective gear ratio thereof to maintain engine operation on or about the contour. In either case, fuel efficient operation may be optimized.
摘要:
In a method for the longitudinal control of a vehicle, where information from a navigation system is recorded and where a target value of at least one parameter for longitudinal control is determined in dependence on the information from the navigation system, the information from the navigation system is used to determine the probability with which the vehicle will drive onto a highway entrance. When the probability is higher than a specified threshold the control unit uses a longitudinal acceleration that is increased compared to regular operation.

A method for controlling traffic in order to reduce air pollution includes reading in at least one pollution signal that represents at least one parameter of a movement of a vehicle in a predetermined relation to a threshold value and a geographical position of the vehicle; and, based on the pollution signal, outputting a change signal for changing at least one parameter of at least one infrastructure unit in surroundings of the position in order to control the traffic.
