Abstract

The invention relates to the technical field of automobiles, in particular to a composite tire pressure monitoring method and a tire pressure monitoring device. The composite tire pressure monitoringmethod comprises: acquiring a first rotational speed of a first tire in which a pressure sensor is installed, and a second rotational speed of a second tire in which a pressure sensor is not installed; reading a first tire pressure value of the first tire detected by the pressure sensor; adjusting an initial tire pressure rotational speed relationship according to the first rotational speed and the first tire pressure value, to obtain a real-time tire pressure rotational speed relationship, wherein the initial tire pressure rotational speed relationship is calibrated as the corresponding relationship between the tire pressure value and the rotational speed in the initial state; obtaining a second tire pressure value of the second tire using the second rotational speed and the real-time tire pressure rotational speed relationship. In the scheme, the tire pressure value of each tire can be obtained in real time and accurately, and the corresponding relationship between the tire pressurevalue and the rotational speed can be obtained by calibrating the tire pressure value and the rotational speed in advance, thereby reducing the complexity of obtaining the second tire pressure and further reducing the energy consumption of the system.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular, the invention relates to a compound tire pressure monitoring method and tire pressure monitoring equipment. Background technique [0002] During the high-speed driving of a car, tire failure is the most worrying and most difficult to prevent for all drivers, and it is also an important reason for sudden traffic accidents. According to statistics, more than 70% of traffic accidents on expressways are caused by blown tires. How to monitor tire pressure and prevent blown tires has become an important issue for safe driving. [0003] Existing tire pressure monitoring systems mainly include two types: direct type and indirect type. The tire pressure measured by the direct type tire pressure monitoring system has high accuracy, but the cost is relatively high due to the need to install four tire pressure sensors. The indirect tire pressure monitoring system relies on the wheel speed...
