Unmanned vehicle driving blind area eliminating device and application method thereof

Abstract

The invention relates to an unmanned vehicle driving blind area eliminating device which comprises a positioning base, a detecting post, ranging devices, a monitoring camera and a control system. Thepositioning base refers to a closed cavity structure with rectangular cross section. The front surface of the positioning base is connected with the detecting device; at least four loading surface areuniformly distributed on the front end face of the detecting device; the ranging devices are arranged on the loading surfaces. The monitoring camera is installed on the front end face of the detecting post through a pan-tilt mechanism. The control system is embedded in the positioning base and in electric connection with the ranging devices, the monitoring camera, the pan-tilt mechanism and an on-board computer respectively. The application method of the device includes two step such as installation of equipment and blind area detection. The unmanned vehicle driving blind area eliminating device has the advantages that the device is easy to control, convenient to install, high in detection and running precision, flexible and convenient to regulate, and further, the device can achieve continuous detection to obstacles according to their locations, regulate running state flexibly and realize reduction of energy consumption.

Description

technical field [0001] The invention relates to a vehicle driving assistance system, which belongs to the technical field of unmanned driving. Background technique [0002] During the driving process of the vehicle, there are blind spots for the driver to observe the positions on both sides of the vehicle and within a certain distance from the front of the car. Therefore, the driver cannot observe the obstacles and pedestrians in the blind spot during the operation of the vehicle. It is easy to cause traffic accidents and vehicle damage, which seriously affects the safety of vehicle operation. In response to this problem, the current main practice is to install several surveillance cameras evenly distributed around the vehicle to realize 360° observation and elimination of the surrounding environment of the vehicle. The need for blind spots, although this method meets the needs of eliminating blind spots of vehicles to a certain extent, but when observing the blind spots of ...

Problems solved by technology

[0002] During the driving process of the vehicle, there are blind spots for the driver to observe on both sides of the vehicle and within a certain distance from the front of the car. As a result, the driver cannot observe obstacles and pedestrians in the blind spot during the running of the vehicle, which is extremely difficult. It is easy to cause traffic accidents and vehicle damage, which seriously affects the safety of vehicle operation. To solve this problem, the current main method is often to install a number of surveillance cameras evenly distributed around the vehicle to realize 360° observation of the surrounding environment of the vehicle and eliminate The need for blind spots. Although this method meets the needs of eliminating vehicle blind spots to a certain extent, when observing vehicle blind spots, on the one hand, the vehicle needs to be in a specific driving state before blind spot observation can be performed, and continuous observation of blind spots cannot be performed. On the other hand, in the blind spot observation operation, the detection and positioning accuracy of obstacles is poor, and during the operation, the detection equipment cannot be effectively selected and adjusted according to the position of the obstacle, which requires continuous operation of the equipment, which also leads to the failure of the detection equipment. The flexibility of operation and control is poor, and the energy consumption of the equipment is relatively high, which cannot effectively meet the needs of actual use. Therefore, in view of this situation, it is urgent to develop a blind spot elimination device and method for unmanned vehicles to meet the needs of actual use.
