Method for monitoring dynamic load of intelligent sensing wheel based on wheel load

Abstract

The invention discloses a monitoring method based on wheel load type intelligent sensing wheel dynamic load. The method comprises the following steps: an intelligent sensing module is arranged on a hub equatorial plane of each wheel of a motor vehicle, an intelligent sensing unit without gyroscopic inertia is arranged in the vehicle, and an intelligent sensing unit is hung in the vehicle to carry out complete inspection of the driving condition of the vehicle. Signal conditioning, digitalization, posture algorithm and dynamic load algorithm are carried out to various sensing signals to obtain main dynamic load parameters of the wheel. The dynamic load parameters are merged and analyzed by multiple sensing data and can be used for monitoring and actively evaluating the driving safety condition of a motor vehicle. The method can previously warn overload, tyre burst, brake performance fault, and the like of the motor vehicle, and is beneficial to avoiding and reducing the occurrence of traffic accidents.

Description

technical field [0001] The invention relates to the field of monitoring the safe running state of motor vehicles, in particular for monitoring the real-time situation of wheel dynamic loads during the running of the motor vehicle.

Problems solved by technology

[0004] At present, the monitoring of the dynamic load of the wheel is only an attempt to indirectly calculate the static load of the wheel by measuring parameters such as tire speed and pressure. Under road conditions, the body and tires are in different postures, and the dynamic load of the whole vehicle can not effectively monitor the dynamic load of the wheel, which is not conducive to the prediction and evaluation of dangerous conditions such as overloading and blowout of motor vehicle tires during operation
