Problems solved by technology

[0003] The steering wheel vibration function is based on the scene of fatigue driving and lane departure warning system. It reminds the driver through a voice alarm, or through the power-assisted motor to intervene in the steering wheel to generate a single fixed-frequency vibration to remind the driver. However, the

Abstract

The invention relates to the field of intelligent driving, in particular to a steering control method and device for audio environment interaction. The method comprises the steps that a sensing layer captures real-time audio data in a vehicle through a sound sensor, wherein the real-time audio data comprise sound intensity voltage data and sound wave simulation data; the decision-making layer converts the received real-time sound intensity voltage data through a torque coefficient to obtain a torque control parameter; the decision layer carries out fast Fourier transform and frequency coefficient processing on the received real-time sound wave simulation data to obtain a current loading speed; the execution layer inputs a real-time torque control parameter and a current loading speed into a motor control unit, and controls a steering wheel to generate rhythm vibration matched with the current real-time audio data; real-time music audio in a vehicle can be captured for audio amplitude-frequency conversion and transmitted to the motor control unit, so that the steering wheel generates rhythmic vibration, the immersion of a driver to driving is enhanced, and the driving safety is improved.

Description

technical field [0001] The application relates to the field of intelligent driving, and relates to technologies combining single-chip control, motor control, digital audio amplitude-frequency conversion, steering control, etc., and in particular to a steering control method and device for audio environment interaction. Background technique [0002] With the increasing severity of traffic safety problems and the rising incidence of traffic accidents, more and more attention has been paid to vehicle collision avoidance warning technology. Collision avoidance warning means that during the driving process of the vehicle, according to the surrounding vehicles, pedestrians, environment and other conditions, it will issue an early warning to the driver of potential collision danger in a timely manner, so that the driver can take measures in advance to avoid accidents. [0003] The steering wheel vibration function is based on the scenarios of fatigue driving and lane departure warn...
