Problems solved by technology

During the operation, due to the impact of the rescued vehicle, the overall center of gravity (the overall center of gravity of the rescue vehicle and the rescued vehicle) will change, and may even exceed the safe range, which will cause the rescue vehicle itself to roll over or tip over

Embodiment Construction

[0049] In recent years, my country's rescue vehicle industry has developed rapidly. However, according to the statistics of relevant departments, the accident rate of rescue vehicles rolling over or overturning is also increasing year by year. The reason is that in addition to the subjective factors such as illegal operations, inexperience and poor management of the operator, the safety monitoring device of the rescue vehicle is not perfect, and the inability to provide accurate status information and safety warnings for the driver is also an unavoidable objective factor.

[0050] Due to the work requirements of the rescue vehicle, the rescue vehicle needs to use the boom to lift the rescued vehicle and other operations. During the operation, due to the influence of the rescued vehicle, the position of the overall center of gravity (the overall center of gravity of the rescue vehicle and the rescued vehicle) will change, and may even exceed the safe range, which will cause the...

Abstract

The invention discloses a rescue vehicle overall gravity center plane position estimation method. Plane positions of the gravity center of the rescue vehicle itself and the gravity center of a rescued vehicle are measured respectively; the plane position of the overall gravity center is acquired through derivation of a resultant moment theorem; and on the basis, a robust filtering algorithm is used for calculating the accurate estimation value of the overall gravity center plane position. The method of the invention can be used for safety monitoring and dangerous condition early warning for the rescue vehicle, and has the advantages of high precision, low cost, good real-time performance and the like.

Description

technical field [0001] The invention relates to a method for estimating the plane position of the overall center of gravity of a rescue vehicle under lifting conditions, in particular to a method based on H ∞ The method for estimating the overall center of gravity plane position of rescue vehicles based on robust filtering aims to provide safety monitoring and warnings of dangerous postures for rescue vehicles, and belongs to the field of safety warnings for rescue vehicles. Background technique [0002] In recent years, my country's rescue vehicle industry has developed rapidly. However, according to the statistics of relevant departments, the accident rate of rescue vehicles rolling over or overturning is also increasing year by year. The reason is that in addition to the subjective factors such as illegal operations, inexperience and poor management of the operator, the safety monitoring device of the rescue vehicle is not perfect, and the inability to provide accurate s...
