Vehicle dead zone early warning system

Abstract

The invention relates to a vehicle dead zone early warning system. The vehicle dead zone early warning system comprises a turning recognition unit, a speed detection unit, a central control unit, a modeling unit and a dead zone early warning unit, wherein the turning recognition unit is used for recognizing a turning signal of a vehicle; the speed detection unit is used for detecting a speed of the vehicle in a turning state; the middle control unit obtains dead zone information and projects the dead zone information to the corresponding dead zone ground through a projection device based on the vehicle turning signal and the vehicle turning speed; the modeling unit obtains a dead zone three-dimensional model and displays the dead zone three-dimensional model inside the vehicle based on the vehicle turning signal and the vehicle turning speed; the dead zone early warning unit sends an early warning prompt to a driver based on the dead zone information and the dead zone three-dimensional model. In the vehicle dead zone early warning system, when the vehicle makes a turn, the purpose that the driver, other vehicles and passers-by are warned can be achieved, and the occurrence of an accident when the vehicle makes a turn is prevented.

Description

technical field [0001] The invention relates to the field of vehicle turning early warning, in particular to a vehicle blind spot early warning system. Background technique [0002] In the prior art, due to the large size of the vehicle, the long body, the high driver's seat and the limited display range of the rearview mirror, the driver has a blind spot in the daily driving process, and the driver has no vision when driving forward, reversing and turning. When turning around, it is often impossible to detect pedestrians, electric vehicles, motorcycles and other small vehicles near the front, rear or side of the vehicle. When pedestrians or small vehicles are close to large trucks, it may cause vehicle collisions or even cause pedestrians to be involved in the vehicle. life-threatening. [0003] A large proportion of traffic accidents are due to large vehicles when turning. It is found that when the car body is relatively long, the rear wheels do not follow the track of t...

In this case, traffic accidents are likely to occur, and pedestrians or vehicles will be crushed

[0004] For example, the Chinese invention patent application with the application number 201610608274.8 discloses a heavy-duty truck steering warning auxiliary device and warning method, which includes: an early warning component inside the vehicle and an early warning component outside the vehicle. The display on the indoor instrument panel and the vehicle travel recorder, the display is connected with the vehicle travel recorder, and the vehicle travel recorder is also connected with an alarm indicating device; the external early warning components include radar detection components and high-definition camera components, and the The radar detection component and the high-definition camera component are set in pairs on the corresponding position on the truck body corresponding to the blind spot of the truck; the external early warning component is connected with the vehicle driving recorder of the vehicle early warning component, and the vehicle driving recorder is set with obstacles. The dynamic prediction module is used to predict the relative track of the obstacle in the blind spot of the vehicle and the vehicle, and display the predicted result on the display. , the device makes accurate and fast judgment again, and can stop quickly in case of an emergency to avoid dangerous situations, but it does not solve the occurrence of dangerous situations when the vehicle is turning

[0005] Another example is the Chinese invention patent with application number 201610689848.9, which discloses a motor vehicle turning warning system, which includes a multi-angle image capture system, an obstacle detection system, a central computing center, and a drive system. The video captures the road condition environment and transmits the road condition information to the central computing center; the obstacle detection system detects the obstacles on both sides of the motor vehicle through ultrasonic radar, and transmits the detection results to the central computing center. The information transmitted by the capture system and the obstacle detection system calculates the specific angle and speed of the turning of the motor vehicle, and sends the command bolt to the drive system, which drives the vehicle to turn. It is suitable for unmanned motor vehicles and can be used when the vehicle needs An early warning signal is issued when turning, so that the motor vehicle can turn smoothly and safely, which solves the early warning when the vehicle needs to turn, and does not solve the occurrence of dangerous situations when the vehicle turns
