Embodiment Construction

[0022] An intelligent intervention method based on integrated TPMS, comprising the following steps:

[0023] Step 1, the direct type TPMS monitors the tire pressure and temperature parameters in real time, and the indirect type TPMS monitors the wheel speed parameters in real time, and the tire pressure, temperature and wheel speed parameter signals are sent to the host computer or the vehicle body control module including the host computer in real time;

[0024] Among them, the integrated TPMS is a combination of direct TPMS and indirect TPMS.

[0025] Wherein, the direct type TPMS monitors tire pressure and temperature parameters in real time, and the direct type TPMS is provided with sensors, and the sensors can be configured as one or more sensors for measuring tire parameter values, for example, the sensors can be configured as pressure sensors for measuring tire pressure, and include additional other sensors, such as one or more temperature sensors. The sensor may be in...

Abstract

The invention provides an intelligent intervention method based on an integrated TPMS. The intelligent intervention method comprises the steps that S1, direct type TPMS real-time monitoring is conducted on tire pressure and temperature parameters, indirect type TPMS real-time monitoring is conducted on wheel speed parameters, and signals of the tire pressure, the temperature parameters and the wheel speed parameters are sent to a host machine in real time; S2, the host machine synthesizes the tire pressure, the temperature parameters and the wheel speed parameters to judge that a vehicle statebelongs to a normal state or abnormal state in real time; S3, when a vehicle is at the abnormal state of tire bursting, values of the tire pressure, the temperature parameters and the wheel speed parameters deviate from normal threshold values of the tire pressure, the temperature parameters and the wheel speed parameters, and a deviation signal is sent to an intelligent intervention system suchas an EPS system, an ESP system and an ABS system; and S4, the intelligent intervention system receives the deviation signal to conduct intelligent intervention, so that the vehicle decelerates and runs in a straight line till the vehicle is at a vehicle stopped state. According to the intelligent intervention method, when tire bursting occurs on the vehicle, the vehicle can still safely run tillthe vehicle is at the vehicle stopped state, and rollover or collision is prevented.

Description

technical field [0001] The invention relates to the field of automobile intelligent control, in particular to an integrated TPMS-based intelligent intervention method. Background technique [0002] TPMS is the English abbreviation of Tire Pressure Monitoring System, which is a monitoring system used to monitor the blind spots in the car driving - tire pressure and temperature. TPMS (Tire Pressure Monitoring System), this concept is still relatively new in China, but in the United States, federal legislation has been formulated and enforced to implement TPMS regulations. [0003] Existing tire pressure monitoring systems are mainly divided into two types: [0004] A direct tire pressure monitoring system is also called PSBTPMS. PSBTPMS uses a pressure sensor installed on the tire to measure the air pressure and temperature of the tire, and uses a wireless transmitter to send the pressure information from the inside of the tire to the central receiver module. system, and the...
