Problems solved by technology

However, when the vehicle is driving, due to factors such as noise and concentration, it is easy for the driver to ignore the sound prompts of obstacles, which will lead to scratching and collision accidents of the vehicle, resulting in economic losses and even serious traffic accidents.

Embodiment Construction

[0031] Such as figure 1 As shown, the implementation steps of the vehicle obstacle monitoring method based on steering wheel vibration in the embodiment of the present invention are as follows:

[0032] 1) Set the minimum obstacle distance for sending out reminders;

[0033] 2) When the vehicle is running, the ranging radar is used to detect the distance of the obstacle closest to the vehicle body;

[0034] 3) Compare the currently detected obstacle distance with the minimum obstacle distance in real time, and when the obstacle distance is smaller than the minimum obstacle distance, apply vibration to the steering wheel of the vehicle to alert the driver of the approaching obstacle.

[0035] Applying vibration to the steering wheel of the vehicle in step 3) specifically means: first obtain the difference between the obstacle distance and the minimum obstacle distance, then adjust the vibration frequency according to the difference, and apply vibration to the vehicle steering ...

Abstract

The invention discloses a vehicle obstacle monitoring method based on vibration of a steering wheel and a device. The vehicle obstacle monitoring method comprises the following steps of: 1) arranging the minimum obstacle distance for sending out prompt; 2) detecting the obstacle distance closest to a vehicle body through a distance-measuring radar when a vehicle runs; and 3) when the obstacle distance is less than the minimum obstacle distance, applying vibration on the steering wheel of the vehicle to send out an obstacle proximity prompt to a driver. The monitoring device comprises a control unit, a radar distance-measuring unit and a vibration unit, wherein the radar distance-measuring unit is used for detecting the obstacle distance closest to the vehicle body; the vibration unit is used for sending out a vibration prompt according to the obstacle distance; the control unit is connected with the radar distance-measuring unit; the vibration unit comprises at least one vibrator fixed on the steering wheel of the vehicle; and the vibrator is connected with the control unit. The invention has the advantages that the implementation cost is low, the safety effect of driving is improved, the reminding is intuitive and effective, and the application range is wide.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a method and device for monitoring vehicle obstacles. Background technique [0002] With the development of social economy, automobiles have been widely used and become a part of people's life. However, due to factors such as driving habits, vehicle blind spots, and complex environments, vehicle scratches are inevitable. In the final analysis, there is a lack of effective obstacle monitoring methods. The currently known obstacle monitoring method is the reversing radar, and the reversing radar generally only sends a sound prompt when the vehicle is close to the obstacle. However, when the vehicle is driving, due to factors such as noise and concentration, it is easy for the driver to ignore the sound prompts of obstacles, resulting in scratching and collision accidents of the vehicle, resulting in economic losses, and even serious traffic accidents.
