- نبذة مختصرة :
A surroundings modeling device for a driver assistance system for a motor vehicle, includes a separating device configured to separate a total vehicle surroundings model into a static vehicle surroundings model based on a first look-ahead distance and a dynamic vehicle surroundings model based on a second look-ahead distance. A first real-time computing device is configured 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 is configured to calculate the static vehicle surroundings model on the basis of the second look-ahead distance with a characteristic response time. A situation analysis device is configured to change the separation process on the basis of an analysis of the total vehicle surroundings model.

- Claim:
3. The device according to claim 1 , wherein the first real-time computing device comprises a plurality of control blocks and/or wherein the second real-time computing device comprises a plurality of control blocks.
- Claim:
4. The device according to claim 3 , wherein the plurality of the control blocks of the first real-time computing device comprises a chain and/or wherein the plurality of the control blocks of the second real-time computing device comprises a chain.
- Claim:
5. The device according to claim 1 , wherein the first real-time computing device is configured to calculate the dynamic vehicle surroundings model on the basis of the first look-ahead distance of up to 200 meters within a maximum response time of up to 10 seconds.
- Claim:
6. The device according to claim 1 , wherein the first real-time computing device is configured to output a calculated total surroundings model and/or a calculated trajectory planning on the basis of the dynamic vehicle surroundings model with a first calculation cycle of up to 5 seconds.
- Claim:
7. The device according to claim 1 , wherein the second real-time computing device is configured to output a calculated total surroundings model and/or a calculated trajectory planning on the basis of the static vehicle surroundings model with a second calculation cycle of up to 10 seconds and with a range of up to 1000 meters.
- Claim:
8. The device according to claim 1 , wherein the first real-time computing device is configured to calculate the dynamic vehicle surroundings model with a first integrity level, and wherein the second real-time computing device is configured to calculate the static vehicle surroundings model with a second integrity level.
- Claim:
9. The device according to claim 8 , wherein the first integrity level is higher than the second integrity level.
- Claim:
10. A surroundings modeling method for a driver assistance system for a motor vehicle, wherein the method comprises: separating 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 second look-ahead distance with the aid of a separating device; calculating the dynamic vehicle surroundings model on the basis of the first look-ahead distance within a maximum response time with the aid of a first real-time computing device; calculating the static vehicle surroundings model on the basis of the second look-ahead distance within a characteristic response time with the aid of a second real-time computing device; and changing the separation process of the total vehicle surroundings model to be calculated on the basis of an analysis of the total vehicle surroundings model utilizing a situation analysis device.
