Definitions

the invention relates to a method and a device for obtaining information about the surroundings of a vehicle in a sample vehicle fleet, in which vehicle data are acquired in the vehicle at certain intervals, which correspond to a predetermined time span or a predetermined distance, and are transmitted together with the position data to a traffic computer .
the course of the vehicle speed over time is recorded together with the acceleration of the vehicle and transmitted to the traffic computer;
the traffic computer then derives certain statements about the type of road used and the traffic situation on this road.
the corresponding traffic situation data is derived on the basis of predetermined criteria using appropriate computer programs.
the invention provides for the detection of operating states of units of the vehicle and the determination of characteristic features of the surroundings (environmental features) of the vehicle from the detected operating states on the basis of predetermined decision criteria.
the invention proposes to record the signals controlling the aggregates and to record them over certain predetermined time periods. Similarly, the operating states of the Aggregates of the vehicle are detected via the signals emitted by the aggregates. In addition, it is proposed that the operating states of the units of the vehicle are determined via the effects of the units.
the alternative or commulative methods of data acquisition ensure that all those vehicle data can be recorded and made available to the traffic computer that contain information about the surroundings of the corresponding vehicle, so that the traffic computer can use them to determine the objectively present environmental characteristics .
the method can be carried out completely automatically without involving the driver or other people, which is associated with relatively low costs.
optical fibers are provided for forwarding the light and opto-electronic converters are provided for converting your light signals into electrical quantities.
the invention proposes that the predetermined decision criteria are stored in the form of tables in an electronic memory. This makes it possible to determine the characteristic features of the surroundings of the vehicle using fuzzy logic.
the characteristic features of the surroundings of the vehicle are expediently determined by an on-board computer installed in the vehicle, and the characteristic features of the surroundings are then transmitted to the traffic computer.
the figure shows an embodiment of the device for obtaining information about the surroundings of a vehicle, which is installed in the vehicle.
the device has a transmitting and receiving unit 1 for data transmission to a traffic computer 8.
the device further comprises a central processor unit (CPU) 2, which is connected to a data bus 3.
a memory area 4 organized as a ring memory for storing the acquired data and a working memory area 5 are connected to the data bus 3, wherein a computing program for determining characteristic features of the surroundings of the vehicle is stored in the working memory area 5 on the basis of predetermined decision criteria, the feature determination from Operating states of special units of the vehicle takes place.
sensors / actuators 6 are arranged in the vehicle, which are also connected to the data bus 3.
the device has a GPS receiver 7 for determining the current position data; the GPS receiver 7 is connected to the central processor unit (CPU) 2 via data bus 3.
the device can also be connected wirelessly to the traffic computer 8, which in turn has a transmission and Receiver unit 9 is equipped.
the wireless connection to the traffic computer 8 can be established, for example, via a radio telephone network.
a vehicle of a sample fleet has sensors 6 installed in the vehicle for carrying out the method;
the sensors 6 record continuously changing state variables, in particular the operating states, preferably of several units, such as the rotational speed of the wheels, the steering wheel angle of the steering device, etc.
the rotational speed of the wheels can be determined, for example, optically without contact, i.e. without delay and without mechanical signs of wear.
the vehicle also has sensors 6, the discrete state variables, such as. B. Detect the position of various switches, in particular the switches of the wiper, the lighting system, the rear fog lamp and the fog lights, the rear window heater, etc.
the vehicle is also equipped with devices that allow the operation of active devices (actuators 6) in the vehicle such as the Display and record the anti-lock braking system (ABS) and the traction control system (ASR).
active devices actuators 6
ABS anti-lock braking system
ASR traction control system
the operating state of the active devices is detected in particular via the signals controlling the units and via the signals emitted by the units.
GPS Global Positioning System
the GPS receiver 7 continuously generates position data at predetermined time intervals, which contain the current position (longitude, latitude, time) of the vehicle in a predetermined coordinate system (longitudes, latitudes), as well as direction and / or speed data about the current movement of the Vehicle.
the operating states are queried by the central processor unit (CPU) 2, for example cyclically at certain time intervals, and stored in the memory area 4 organized as a ring memory via the data bus 3.
the oldest data in the ring buffer are constantly overwritten by the new one; the size of the memory area 4 thus determines the maximum amount of data available for evaluation.
data (operating states) stored in the memory area 4 are processed by the central processor unit (CPU) 2 e.g. fetched into the working memory area 5 and a computer program started.
the computing program contains the decision criteria according to which the recorded operating states are assigned to one or more characteristics of the environment.
a certain characteristic of the environment is always present when the individual operating states lie within the tolerance ranges of the operating states that are typical for this characteristic.
the typical tolerance ranges of the operating states must be determined beforehand on the basis of practical experience and entered in the computer program in the form of upper and lower limits defining a tolerance range.
data is also stored in additional sensors installed in the vehicle, e.g. a temperature sensor for determining the outside temperature, also used for evaluation. It is also conceivable to record the ambient air humidity by means of a corresponding sensor and to take it into account in the evaluation.
switch positions of individual units preferably only the number assigned to the position is entered into the computer program for the corresponding environmental feature; If several switch positions are assigned to a characteristic, the corresponding numbers are entered. For example, the wiper switch positions 1, 2, 3 and 4 are assigned to the "rain” environmental feature; the wiper switch position 0 (wiper "off") does not belong to this environmental feature. Switch position 4 detects the environmental feature "heavy rain”; in this case, it is not necessary to query the operating states of further units or sensors in order to record this environmental feature.
the environmental characteristic "dry road” on a freeway corresponds, for example, to a speed range from 100 to 200 km / h, in this case the lower limit is 100 km / h and the upper 200 km / h for the environmental characteristic "dry road”", which is of course only assigned to the recorded operating conditions if all other operating conditions also meet the respective criteria for the characteristic" dry road ", in this case, the operating states of further units or sensors must also be taken into account in order to detect this environmental feature.
the presence of strong cross winds can be deduced, for example, from the intensity of the actuation of the steering system (as a result of constant distractions from the desired direction of travel).
the relevant statement can be further verified by determining the driving speed, which will generally be lower than the usual speed of the respective vehicle in the sample vehicle fleet.
the signals from acceleration sensors of an accident data recorder can also be used, with which the shaking of the side wind on the vehicle can be detected.
the typical tolerance ranges of the operating states can alternatively be stored in the form of a table in the electronic memory 5.
the table then uses the fuzzy logic to filter out the environmental features of the vehicle from the detected operating states.
the assignment of the environmental features can also be done by a hardware circuit.
