Abstract

The embodiment of the invention provides a vehicle collision signal processing method and device. The vehicle collision signal processing method comprises the following steps that a vehicle collisionsignal is obtained through a collision sensor; and a predetermined resonant frequency band obtained through analysis of a resonance test serves as a stopping frequency band, and the vehicle collisionsignal is subjected to bandreject filtering. The vehicle collision signal processing device comprises a band rejection filter, the band rejection filter is connected with the vehicle collision sensorand a vehicle safe air bag controller and is configured to taking the predetermined resonant frequency band obtained through the resonance test as the stopping frequency band, the vehicle collision signal collected by the vehicle collision sensor is subjected to bandreject filtering, and the signal after bandreject filtering is conducted is transmitted to the vehicle safe air bag controller. According to the vehicle collision signal processing method and device, effective information can be reserved as much as possible while noise is caused by resonance filtering.

Description

technical field [0001] The invention relates to the technical field of motor vehicles, in particular to a vehicle collision signal processing method and device. Background technique [0002] Safety systems for vehicles have been widely used. In the safety system of the vehicle, the collision sensor detects the vehicle collision signal and transmits the vehicle collision signal to the controller. The controller controls the operation of the airbag and the like based on the vehicle collision signal. [0003] In the actual driving environment, the vehicle collision signal will include various noises. These noises may cause the controller to make wrong judgments and affect the normal detonation of the airbag. A vehicle collision signal processing method and device are needed to process noise. Contents of the invention [0004] Embodiments of the present invention provide a vehicle collision signal processing method and device. [0005] According to a first aspect, an embo...
