AUTOMATIC DRIVING SYSTEM ABLE TO MAKE DRIVING DECISIONS AND METHOD THEREOF |
摘要 |
The present invention discloses an autonomous driving system able to make driving decisions and a method thereof, which decide a safer vehicle movement, wherein a processor generates a left-turn signal, a forward signal and a right-turn signal, receives and vectorizes a vehicle movement signal and object movement signals to determine whether one object is a dangerous or non-dangerous object, inputs the results into a corresponding equation to generate dangerous and non-dangerous object weights, substitutes the dangerous and non-dangerous object weights into a space weight equation to calculate left-turn, forward and right-turn lane section weights, uses the lane section weights to generate left-turn, forward and right-turn signal weights, generates a movement signal or a braking signal according to whether a highest one of the signal weights is over or below preset weight. |

1. A driving decision method for an autonomous driving system, comprising steps:
a processor generating a left-turn signal, a forward signal and a right-turn signal, and a detection device detecting a vehicle movement signal of a vehicle and a plurality of object movement signals of a plurality of objects; said processor respectively converting said vehicle movement signal and said object movement signals into a vehicle movement vector and a plurality of object movement vectors; said processor determining whether one said object is a dangerous object or a non-dangerous object according to said vehicle movement vector and said object movement vectors, and generating a dangerous object weight or a non-dangerous object weight according to whether said object is said dangerous object or said non-dangerous object; said processor defining left-turn lane sections corresponding to said left-turn signal, forward lane sections corresponding to said forward signal, and right-turn lane sections corresponding to said right-turn signal, and determining left-turn lane section weights, forward lane section weights and right-turn lane section weights according to said dangerous object weight or said non-dangerous object weight of one said danger object or one said non-dangerous object, which will pass through one corresponding said lane section; and said processor generating a left-turn signal weight, a forward signal weight and a right-turn signal weight, and taking a highest signal weight therefrom, and determining whether said highest signal weight is over a preset weight; if yes, said processor generating a movement signal according to said left-turn signal, said forward signal or said right-turn signal, which has said highest signal weight; and if no, said processor generating a braking signal. |
