- the reference point of the vehicle e.g. depending on the standard with a 95 percent or 68 percent probability.
- a method for determining an impairing traffic situation of a first road user with a second road user which has the steps:
- the underlying idea is that uncertainty information determined by the first road user to describe an uncertainty in the position detection of the first road user is converted into a covariance matrix, in particular using a closed formula.
- the position detection serves to determine position information for describing a position of the first road user.
- uncertainty information received from a second road user is converted into a covariance matrix, in particular using a closed formula, to describe an uncertainty in the position detection of the second road user.
- the uncertainty information of the second road user can be determined by the second road user in a manner comparable to that of the first road user.
- the use of covariance matrices is expedient and advantageous in particular when normally distributed errors are present.
- the determination of whether there is an adverse traffic situation between the first road user and the second road user is extremely resource-efficient and can be designed in a variety of application- and situation-specific ways by defining relevant parameters.
- storing, transmitting and calculating using such matrices leads to a general standardization and improvement in data quality vehicle's own environment sensors as part of the sensor data fusion are hereby considerably simplified or made possible in the first place.
- An impairing traffic situation is understood to mean, in particular, a traffic situation which has or can have effects that endanger or influence safety, comfort and/or driving efficiency for the first road user and/or the second road user and/or a third party.
- Safety-impairing effects can be, for example, personal injury and/or property damage.
- a traffic situation that can or would have safety-impairing effects is referred to below as a safety-critical traffic situation, where, for example, a collision or an imminent collision or falling below a certain distance between the first road user and the second road user comes into consideration.
- the first and the second covariance matrix can thus be used to determine a collision probability of the first road user and the second road user.
- the method is intended in particular for execution by an electronic control system or a computing device for data processing of the first road user.
- the covariance matrices determined on the basis of the uncertainty information describe, in connection with the respective positions of the first or second road user, in particular the probability of the first or second road user being present for a relevant area.
- This probability of being present can, for example, be in the form of a multidimensional normal distribution over the area in question, with the maximum of the normal distribution being the highest probability of being present for the first or second road user describes.
- the position of the respective maximum of the uncertainty information of the first road user and/or the second road user as position information for determining the position of the first or second road user, in particular in relation to a respective reference point of the first or second to use road users.
- a covariance matrix basically represents a mathematical representation of a multidimensional normal distribution, with the covariance matrices of the uncertainty information of the first road user and the uncertainty information of the second road user using the respective positions of the first and second road user expediently in the same, for example global, coordinate system, such as WGS84. Accordingly, the position information for describing a position of the second road user can be sent or received, for example represented in a global coordinate system such as WGS 84.
- position information is also recorded to determine a position of the first road user and position information is recorded to determine a position of the second road user.
- the position is detected by the first road user and/or the second road user using a global satellite navigation system (GNSS) such as GPS, Glonass, Galileo, etc., for which the first road user or the second road user expediently has one each corresponding GNSS receiver for determining an own position.
- GNSS global satellite navigation system
- the first road user has computing means for determining the uncertainty information for determining a Uncertainty of a position detection of the first road user and the second road user has computing means for determining the uncertainty information for determining an uncertainty of a position detection of the second road user.
- the uncertainty information of the first road user and/or the second road user describes a dimension of a main axis, a dimension of a secondary axis and an orientation, in particular with regard to the global coordinate system, of an area that reflects the uncertainty of the position detection of the first road user or the second road user .
- the reference point of the relevant road user is located within this ellipse describing the uncertainty when determining the position of the road user concerned, e.g. depending on the standard with a probability of 95 percent or 68 percent.
- the ellipse is expediently defined by a center point or the position in a global coordinate system, the dimensions of a main axis, the dimensions of a secondary axis and the orientation.
- the position information and uncertainty information transmitted by the second road user is received by a vehicle-to-X communication device of the first road user.
- the second road user can also have a vehicle-to-X communication device and transmit the position information and the uncertainty information, with the position information and the uncertainty information being able to be received directly or indirectly. Under direct in this sense is an immediate transmission from the communication device of the second road user understood to the first road user.
- Indirect is understood to mean an indirect transmission from the communication device of the second road user to the first road user in such a way that, for example, at least one further reception and retransmission process of the uncertainty information is carried out by a communication device, for example of another road user, a so-called roadside unit and /or a mobile radio base station, between transmission by the second road user and reception by the first road user.
- a location-dependent superimposition of the local whereabouts described by the first covariance matrix and the second covariance matrix in connection with the respective positions of the first and second road user is used - Probabilities of the first road user and the second road user made.
- the result of a matrix operation comprising the first covariance matrix and the second covariance matrix, is used to determine the presence of an adverse traffic situation between the first road user and the second road user.
- the matrix operation is a linear combination of the first covariance matrix and the second covariance matrix.
- it is an addition or subtraction of the first covariance matrix and the second covariance matrix. Linear combinations or coordinate transformations can be represented particularly resource-efficiently using matrix operations.
- the determination of the existence of an adverse traffic situation is made using correlation assumptions to describe a measure of the correlation of the uncertainty of the position detection of the first road user and the uncertainty of the position detection of the second road user.
- the degree of correlation of the uncertainties describes, for example, correlated effects or effects that reduce a correlation that can be expected for a specific situation on the position detection of the first and second road user.
- a correlated effect can be seen, for example, in the case of atmospheric influences, which can usually be assumed to be essentially the same for both road users for an area that is relevant as in the present case. Environmental influences can also cause a greater or lesser correlation in this regard.
- the correlation assumptions can be designed to be adaptive.
