Embodiment Construction
[0028] Embodiment of vehicle control system based on obstacle height:
[0029] The vehicle control system based on the obstacle height proposed in this embodiment, such as figure 1 The system architecture shown, including the acquisition unit (ie figure 1 Perception system in), processing unit (i.e. figure 1 Central control in) and execution unit (ie figure 1 in the executive body). The acquisition unit is connected to the signal input end of the processing unit, and the signal output end of the processing unit is connected to the execution unit.
[0030] Acquisition unit such as Figure 2a , Figure 2b , Figure 2c 8 ranging radars are shown, namely ranging radar 1, ranging radar 2, ranging radar 3, ranging radar 4, ranging radar 5, ranging radar 6, ranging radar 7 and ranging radar 8 , the distribution of acquisition units in the vehicle is as follows: ranging radar 1 and ranging radar 3 are the first group of detection modules, ranging radar 2 and ranging radar 4 are...

The invention relates to a vehicle control system based on obstacle height and a vehicle, belonging to the technical field of vehicle safety. The control system includes an acquisition unit, a processing unit and an execution unit, the execution unit includes an alarm module, the acquisition unit includes at least one group of detection modules, and each group of detection modules includes a first range-finding radar and a second range-finding radar, according to the group The height difference of the installation distance between the first ranging radar and the second ranging radar, and the obstacle distance detected by the two ranging radars determine the height difference between the obstacle and the top of the vehicle or the distance between the obstacle and the front end of the vehicle; when the vehicle When the height difference from the obstacle or the distance is less than the safety distance, the alarm module in the control execution unit will give an alarm. The system can detect the height of obstacles through the two corresponding ranging radars, which greatly reduces the cost, and uses the fusion information of the two ranging radars for judgment, and the data processing is simple.
Description
technical field [0001] The invention relates to a vehicle control system based on obstacle height and a vehicle, belonging to the technical field of vehicle safety. Background technique [0002] Due to the structural design of the vehicle, it is inevitable that the driver will form a blind spot when the vehicle is driving. In view of this situation, the most commonly used solution is to install radar and cameras on the vehicle, and establish a 360-degree surround view system to solve the problem of the vehicle. Blind spot problem. However, for passenger cars, the height of the vehicle is also a blind spot that cannot be ignored. When the vehicle passes a height limit pole, a viaduct or a path with low branches, the height information observed by the driver is limited. If judged by experience, it will cause Unnecessary accidents, for this reason, someone proposes to install lidar at the front of the vehicle, such as the Chinese invention patent application document with the ...
