Abstract

The invention relates to a surroundings modeling device (100) for a driver assistance system for a motor vehicle. The device (100) comprises the following: a separating device (10) which is designed to separate a total vehicle surroundings model to be calculated into a static vehicle surroundings model based on a first look-ahead distance and a dynamic vehicle surroundings model based on a secondlook-ahead distance; a first real-time computing device (20) which is designed to calculate the dynamic vehicle surroundings model on the basis of the first look-ahead distance within a maximum response time; a second real-time computing device (30) which is designed to calculate the static vehicle surroundings model on the basis of the second look-ahead distance with a characteristic response time; and a situation analysis device (40) which is designed to change the separation process on the basis of an analysis of the total vehicle surroundings model.

Description

technical field

[0001] The invention relates to a driver assistance system for a motor vehicle.

[0002] In particular, the invention relates to a device and a method for modeling the surrounding environment for a driver assistance system of a motor vehicle. Background technique

[0003] In real-time systems, there are "strong" real-time systems and "weak" real-time systems. Strong real-time systems ensure and provide correct results within a specified maximum response time.

[0004] This places high demands on the real-time performance of the system foundation, such as the operating system.

[0005] For example, it is necessary to use a dedicated real-time operating system, known representatives such as "Development System and Interface for Electronic Equipment in Motor Vehicles" abbreviated as OSEK, or OSEK-OS, which is launched by the OSEK Alliance. The technical specification of the real-time operating system of the system.

[0006] In addition, QNX—a dedicated unix-...
