Abstract

An assistance system and a generation method of dynamic driving information, which acquire object information of an ambient object near by a main vehicle to establish an ambient object relation list of the main vehicle, receive an ambient object relation list of an ambient vehicle, and determine object information of the ambient object relation list of the ambient vehicle before being added in the ambient object relation list of the main vehicle, so as to establish a dynamic driving information graph.

Claims

1. An assistance system of dynamic driving information, comprising:

an ambient vehicle sensing unit, configured to sense at least one ambient object near by a main vehicle to obtain object information;

a wireless communication unit, configured to receive an ambient object relation list from at least one ambient vehicle; and

a processing unit, configured to establish an ambient object relation list of the main vehicle according to the object information of the at least one ambient object, for adding object information of the ambient object relation list of the at least one ambient vehicle in the ambient object relation list of the main vehicle to generate a dynamic driving information graph.

2. The assistance system according to claim 1, wherein the processing unit determines the object information in the ambient object relation lists of the main vehicle and the at least one ambient vehicle;

an object specified by both the object information of the ambient object relation list of the main vehicle and the object information of the ambient object relation list of the at least one ambient vehicle is shown in the dynamic driving information graph when the object information of the ambient object relation list of the main vehicle and the object information of the ambient object relation list of the at least one ambient vehicle satisfy an error condition; and

various objects respectively specified by the object information of the ambient object relation list of the main vehicle and the object information of the ambient object relation list of the at least one ambient vehicle are shown in the dynamic driving information graph when the object information of the ambient object relation list of the main vehicle and the object information of the ambient object relation list of the at least one ambient vehicle do not satisfy the error condition.

3. The assistance system according to claim 1, further comprising a display unit, coupled to the processing unit, is configured to display the dynamic driving information graph.

4. The assistance system according to claim 1, further comprising a memory unit, coupled to the processing unit, is configured to store the ambient object relation lists and the object information thereof.

5. The assistance system according to claim 2, wherein the ambient object is a vehicle or a barrier.

6. The assistance system according to claim 1, wherein the object information comprises an angle and a distance.

7. The assistance system according to claim 6, wherein the object information further comprises a driving direction, time and a driving speed.

8. A generation method of dynamic driving information, comprising:

acquiring object information of at least one ambient object near by a main vehicle;

according to the object information of the at least one ambient object, establishing an ambient object relation list of the main vehicle;

receiving an ambient object relation list of at least one ambient vehicle; and

adding object information of the ambient object relation list of the at least one ambient vehicle in the ambient object relation list of the main vehicle to generate a dynamic driving information graph.

9. The generation method according to claim 8, further comprising the following steps after receiving the ambient object relation list of the at least one ambient vehicle:

determining the object information of the ambient object relation lists of the main vehicle and the at least one ambient vehicle;

if the object information of the ambient object relation lists of the main vehicle and the at least one ambient vehicle satisfy an error condition, showing an object specified by both the object information of the ambient object relation lists of the main vehicle and the at least one ambient vehicle, in the dynamic driving information graph; and

if the object information of the ambient object relation lists of the main vehicle and the at least one ambient vehicle do not satisfy the error condition, showing various objects respectively specified by the object information of the ambient object relation lists of the main vehicle and the at least one ambient vehicle, in the dynamic driving information graph.

10. The generation method according to claim 8, wherein the object information comprises an angle and a distance.

11. The generation method according to claim 8, wherein the object information comprises a driving direction, time and a driving speed.

12. The generation method according to claim 9, wherein the ambient object is a vehicle or a barrier.

13. An assistance system of dynamic driving information, comprising:

a wireless communication unit, configured to receive an ambient object relation list from at least one ambient vehicle; and

a processing unit, configured to receive object information of at least one ambient object near by a main vehicle to establish an ambient object relation list of the main vehicle, and to add the object information of the ambient object relation list of the at least one ambient vehicle in the ambient object relation list of the main vehicle to generate a dynamic driving information graph.
