[0002] At present, during the operation of the vehicle, excessive speed, unstable tire pressure and poor passability between the vehicle and the ground are all important factors leading to vehicle failure and safety accidents. It is often to install a dedicated tire pressure detection device and a distance measuring device based on ultrasonic radar for the vehicle. Although the current method can achieve the detection of vehicle pressure regulation and the detection of obstacles around the vehicle to a certain extent, However, on the one hand, the current tire pressure detection device and the distance measuring device of the ultrasonic radar operate independently, resulting in a lack of effective data aggregation between the detection data of the tire pressure detection device and the distance measuring device of the ultrasonic radar and the vehicle speed. Therefore, it is impossible to comprehensively and effectively conduct comprehensive detection and control of vehicle operation data, the data processing ability is low and the data comprehensive calculation is insufficient, and the unified and coordinated processing of vehicle speed, tire pressure, tire temperature, road undulations and vehicle passability cannot be effectively realized. On the other hand, in the passability detection of vehicles, the angle between the detection axis and the ground of the current ultrasonic radar ranging device has defects such as insufficient rationality, which leads to insufficient passability detection accuracy and cannot effectively and truly reflect the vehicle. The distance between the chassis and the highest and lowest points on the ground leads to the fact that the judgment of vehicle passability cannot effectively meet the needs of vehicle driving. Therefore, in view of this phenomenon, it is urgent to develop a vehicle operating status monitoring device to meet the actual use need
