  • the invention is therefore an object of the invention to provide a driver assistance system of the type mentioned that both the comfort of a driver by additional Information as well as its safety in traffic increased at intersections.
  • the object is achieved by a generic assistance system for a vehicle driver, in which the communication devices for wireless data transmission are formed at least from the control device to the vehicle in a close range.
  • Essential to the invention here is the transmission direction from the control unit of the traffic signal system to vehicles approaching the intersection or standing in a queue of vehicles in front of a stop line at the intersection. From the data of the control of the traffic signal system valuable driver information can be obtained, which presents timely and in driver-friendly form its comfort and safety in the traffic of a road junction can increase.
  • the wireless data transmission is short-range, i. in a near area extending from a roadside communication device at most to about the next adjacent node. As a result, it is not necessary to resort to expensive mobile radio networks, the short-range data transmission can rather be made available to the driver free of charge.
  • the data transmission from the roadside communication device to a vehicle side communication device is configured as a wireless local area network.
  • the WLAN technology English: Wireless Local Area Network
  • the road-side communication device of a driver assistance system on an interrogation unit for retrieving data on the current and future switching state of signalers of the traffic signal system and a transmitting device for transmitting the retrieved data to the vehicle.
  • the current position in the sequence of the signal program is via the current but also about future switching states with regard to the blocking and release times, including their lane assignments. If vehicle detector data are also available in the control unit, current but also future estimated lengths of queues at the approximated intersection can be determined and transmitted.
  • the interrogation unit of the driver assistance system is configured to cyclically repeat the data on the future switching state of signalers.
  • the future switching state of the signal generator could be updated every second.
  • the vehicle-side communication device has a receiving device for data transmitted by the control device, a processing device for processing the received data to driver information and a display device for displaying the driver information.
  • driver information such as the current waiting time in a vehicle queue to pass the stop line and the current removal of the vehicle to the stop line in a simple, directly accessible to a driver on the display device.
  • the processing unit of the driver assistant according to the invention is designed to relate the transmitted data with vehicle data and derive therefrom driving recommendations and / or driver warnings. From the comparison of own vehicle data, such as position and speed, with the signaling and traffic status data At the present intersection, not only general driver information but also recommendations for a specific driving behavior as well as warnings to the driver against dangerous situations can be generated.
  • the display of such driver information supports an economical and safe driving behavior in the area of traffic signal-controlled road intersections.
  • the vehicle-side communication device has a navigation satellite navigation device for obtaining vehicle data.
  • the assistance system includes a GPS receiver
  • the system has a time base as well as map data that allow precise indication of the position and speed of the vehicle.
  • the estimated time of arrival of the vehicle at the stop line of the intersection can be calculated and a comparison with the present at this time switching states of the signal generator can be performed.
  • the driver can be recommended on the display device, a speed at the constant compliance he will pass the present intersection in a green window.
  • the vehicle drives off a route proposed by the route guidance device, it can be changed dynamically by providing a lane recommendation or a turn-by suggestion in knowledge of the traffic state.
  • a driver warning can be issued.
  • Another example of a driver alert is to indicate at an intended turn at the intersection in question that pedestrians and / or cyclists whose path will be crossed by the turning vehicle will have GREEN in parallel.
  • the vehicle-side communication device has signaling means for emitting acoustic and / or visual driver warnings.
  • signaling means for emitting acoustic and / or visual driver warnings.
  • this can result in the delivery of particularly noticeable warning signals to the driver.
  • a piercing beep could be triggered as an audible and a flashing warning light on the instrument board as an optical warning signal.
  • the vehicle-side communication device of the driver assistance system is connected to at least one electronically controlled vehicle component, wherein the vehicle component can be influenced on the basis of the transmitted data of the control device. It is conceivable, for example, to install a connection from the vehicle-side communication device to the engine control, which allows automatic throttling of the stationary gas during the waiting time at a road intersection. This leads to significant fuel savings and a reduction of pollutant emissions.
  • the communication devices are also designed for wireless data transmission from the vehicle to the control unit in a vicinity of the vehicle. Due to the possibility of data transmission from the vehicle to the control unit of the traffic signal system release requirements can be issued to a traffic signal system of individual traffic participants. As a result, trackside traffic detectors and their sometimes complex and traffic-obstructing installation can be saved.

  • signal generator 22 may be provided for different lanes of access roads to the intersection 10, as well as pedestrians, cyclists or trams.
  • the light signals of the signal generator 22 are switched by a running in a control unit 21 signal program according to predetermined release and blocking times.
  • An essential component of the driver assistance system according to the invention is formed by a communication device 23 arranged on the road side, by means of which data 22T can be called up via the current switching state and data 22T 'via a future switching state of the signal generator 22 from the control device 21.
