Definitions
- a method for training at least one algorithm for a control unit of a motor vehicle, a method for optimizing a traffic flow in a region, a computer program product and a motor vehicle are described here.
- a method for operating a vehicle is known from DE 102017 007468 A1, measurement data of a road traffic situation being determined and a future road traffic situation being determined in a traffic simulation based on the measurement data.
- the measurement data are determined by means of the vehicle's own determination units for the vehicle and / or at least one other vehicle involved in the road traffic situation and sent to a central processing unit.
- the central computing unit is used to carry out the traffic simulation for a predetermined time horizon and, depending on the results of the traffic simulation, the central computing unit determines vehicle parameters and sends them to the vehicle and / or the at least one other vehicle that when the vehicle parameters are set meter a driving style of the vehicle and / or the at least one further vehicle is adapted to promote a traffic flow.
- a corresponding traffic flow metric can be, for example, an average speed that should correspond to a certain minimum speed as far as possible.
- a minimum speed can be specified or derived from theoretical considerations, for example taking into account the particularities of a relevant region, for example taking into account applicable maximum speeds. Parameters such as traffic lights can also be taken into account.
- the route via a corresponding traffic focus depicts a real deployment scenario, namely the routing of traffic by using a corresponding automatically driving lead vehicle.
- the traffic simulation can map a real traffic situation in the operational area more precisely.
- the traffic flow metric contains an average speed during the mission.
- Reinforcing learning algorithms are particularly suitable for optimization tasks like this one.
- Another independent subject matter relates to a device for training at least one algorithm for a control unit of a motor vehicle, the control unit being provided for implementing an automated or autonomous driving function by intervening in units of the motor vehicle on the basis of input data using the at least one algorithm , the algorithm being trained by a self-learning neural network, the device being designed to carry out the following steps: a) Providing a computer program product module for the automated or autonomous driving function, the computer program product module containing the algorithm to be trained and the self-learning neural Network contains, b) providing a simulation environment with simulation parameters, wherein the simulation environment contains map data of a real existing application area, the motor vehicle, wherein a behavior of the motor vehicle by a Rule set is determined, c) provision of real-time traffic data of the real existing application area as well as re-enactment of the traffic situation in the simulation environment; d) Determining traffic focal points on the basis of the real-time traffic data on the basis of a
- the device is set up to select another mission and to repeat the method with the other mission when step i) is reached.
- a mission involves driving a route from at least one starting point to at least one Represents the destination point across a traffic focal point.
- the real-time traffic data contain infrastructure information.
- the device is set up to use an optimization algorithm when reproducing the traffic situation in the simulation environment in order to minimize deviations between the simulation environment and the real-time traffic data.
- the traffic flow metric contains an average speed during the mission.
- infrastructure information e.g. information on traffic light switching, lane regulation or the like
- Another independent subject relates to a lead vehicle for optimizing a traffic flow by regulating the driving behavior of vehicles driving behind the lead vehicle in a region, the at least one lead vehicle being an autonomously driving vehicle, the at least one lead vehicle having an algorithm controlling the lead vehicle having, which is trained according to the method described above.
- the at least one lead vehicle has means for receiving infrastructure information from an infrastructure controller, the lead vehicle being set up to adapt its driving behavior to the received infrastructure information.
- Another independent subject matter relates to a computer program product with a computer-readable storage medium on which instructions are embedded which, when executed by at least one computing unit, have the effect that the at least computing unit is set up to carry out the method of the aforementioned type.
- the method can be carried out on one or more processing units distributed so that certain method steps are carried out on one processing unit and other process steps are carried out on at least one other processing unit, with calculated data being able to be transmitted between the processing units if necessary.
- Another independent subject matter relates to a motor vehicle with a computer program product of the type described above.
- FIG. 3 shows a road map of a real existing application area
- FIG. 4 shows a flow chart of a training method.
- Fig. 1 shows a motor vehicle 2, which is set up for automated or autonomous driving.
- the motor vehicle 2 is provided as a guide vehicle for regulating traffic at traffic focal points.
- the control unit 4 is connected, on the one hand, to a number of environmental sensors that allow the current position of the motor vehicle 2 and the respective traffic situation to be recorded. These include environmental sensors 10, 11 at the front of the motor vehicle 2, environmental sensors 12, 13 at the rear of the motor vehicle 2, a camera 14 and a GPS module 16.
- the environmental sensors 10 to 13 can, for example, radar, lidar and / or Include ultrasonic sensors.
- the computing unit 6 has loaded the computer program product stored in the memory 8 and executes it. On the basis of an algorithm and the input signals, the computing unit 6 decides on the control of the motor vehicle 2, which the computing unit 6 would achieve by intervening in the steering 22, engine control 24 and brakes 26, which are each connected to the control unit 4.
- Data from sensors 10 to 18 are continuously temporarily stored in memory 8 and discarded after a predetermined period of time so that these environmental data can be available for further evaluation.
- the algorithm was trained according to the method described below.
- FIG. 2 shows a computer program product 28 with a computer program product module 30.
- the computer program product module 30 has a self-learning neural network 32 that trains an algorithm 34.
- the self-learning neural network 32 learns according to methods of reinforcement learning, d. H.
- the algorithm 34 By varying the algorithm 34, the neural network 32 tries to obtain rewards for improved behavior in accordance with one or more metrics or standards, that is to say for improvements to the algorithm 34.
- the algorithm 34 can essentially consist of a complex filter with a matrix of values, usually called weights by those skilled in the art, that define a filter function that determines the behavior of the algorithm 34 as a function of input variables that are presently recorded by the environmental sensors 10 to 18 are determined and control signals for controlling the motor vehicle 2 are generated.
- the computer program product module 30 can be used both in the motor vehicle 2 and outside the motor vehicle 2. It is thus possible to train the computer program product module 30 both in a real environment and in a simulation environment. In particular, according to the teaching described here, the training begins in a simulation environment, since this is safer than training in a real environment.
- the computer program product module 30 is set up to set up and evaluate a metric that is to be improved.
- such a metric is, for example, an average speed for passing a traffic focal point, i.e. an area in which the traffic flows particularly poorly, at least at certain times.
- the motor vehicle 2 not only regulates the speed of the following vehicles 42, 44 and 46, but also the other behavior, in particular the braking behavior of the corresponding vehicles 42, 44 and 46, for example by limiting a maximum deceleration of the motor vehicle 2, that is to say by especially Gentle driving. This can reduce the likelihood that the column of vehicles 42, 44 and 46 will brake too hard and the flow of traffic will come to a standstill as a result.
- the computer program product module contains the algorithm to be trained and a self-learning neural network.
- a simulation environment is then made available on the basis of real map data.
- the simulation environment can also contain other road users and their missions.
- a mission is determined in the simulation environment.
- the mission can be the driving of a specific route from a starting point to a destination point through a traffic focus.
- the simulation is then carried out and an average speed is determined.
- the average speed is compared with an average speed to be achieved as a traffic flow metric.
- the process can be repeated using other missions and the algorithm can be used more universally.
