The control system 1 analyzes and processes the collected information, obtains the control information, and sends an instruction to the actuator 3. The detection device 4 is composed of nine visual sensors 401 , gyroscope 402 , ultrasonic sens...

Embodiment 3

[0029] Embodiment 3: as Figure 1 ~ Figure 4 As shown, the operation steps of collision avoidance and obstacle avoidance of unmanned buses are as follows:

[0030] F001, the visual sensor 401, the ultrasonic sensor 403 and the radar sensor 404 in the detection device 4 collect the surrounding environment information and the running state of the object to avoid in real time, and measure the instant status information of the vehicle through the gyroscope 402;

[0031] F002, when an obstacle is detected on the road, the collected real-time information is transmitted to the control system 1 for processing and analysis, and an avoidance plan is obtained, and the command is transmitted to the actuator 3:

[0032] 1) If the obstacle on the road ahead is only on one side of the vehicle or the target is small, the control system 1 sends an instruction to the actuator 3, and the actuator 3 completes steering and other operations after receiving the instruction, and the vehicle can move ...

Description

technical field [0001] The invention relates to an obstacle avoidance system, in particular to a collision avoidance and obstacle avoidance system and method for an unmanned bus, belonging to the technical field of unmanned buses. Background technique [0002] Nowadays, traffic accidents caused by fatigue driving, drunk driving, failure to avoid, speeding and other reasons are becoming more and more serious, and the emergence of driverless buses provides the possibility for safe driving of vehicles and reduction of traffic accidents. But there is not enough research on the intelligent behavior of driverless buses, and the vehicles are easily damaged when they collide. In order to better ensure the safe driving of unmanned buses in complex environments, functions such as emergency avoidance are very important. The anti-collision and obstacle avoidance function is an indispensable key indicator for intelligent vehicles, and it is also an important guarantee for reliable drivi...
