技術摘要:
本發明係提供一種防止汽車撞擊之偵測方法,其係運用於一車輛上,該偵測方法包括下列步驟:步驟(a):提供至少一偵測裝置以及一線性濾波裝置,該偵測裝置可量測該車輛之一預定資訊,該線性濾波裝置可提高該預定資訊之訊雜比。步驟(b):以該線性濾波裝置接收該預定資訊,且經由提高該訊雜比後,使該預定資訊形成一修正資訊。步驟(c):計算該修正資訊,使該修正資訊形成一分量資訊,該分量資訊為具有一第一方向以及一第二方向之向量分量。步驟(d):再提高訊雜比,使該分量資訊形成一比對資訊。藉由上述之步驟可大幅縮短計算比對資訊之收斂時間,因此可準確估算周邊移動物體之位置變化,預防短時間內可能之突發衝撞。
A detection method for preventing an automobile from colliding is applied to an automobile. The detection method includes the following steps: step (a): providing at least two detection devices, each detection device is used to measure a predetermined information of the automobile. A one-stage linear Kalman filter in each device is used to enhance the signal-to-noise ratio of the predetermined information. In step (b): utilizing the one-stage linear filter to receive the predetermined information and obtain a corrected information from the predetermined information after the signal-to-noise ratio is enhanced. In step (c): calculating the corrected information to obtain a component information having vector components of a first direction and a second direction. In step (d): enhancing the signal-to-noise ratio to enable the component information to be a contrast information. Accordingly, the convergence time of calculating the contrast information can be substantially reduced. The position variation of the surrounding moving objects can be accurately estimated to prevent the sudden collision in a short time.
