Problems solved by technology

The design of the vehicle, the load, and the high-speed centrifugal curve movement will all form an asymmetric structure and uneven quality. These factors will cause the center of gravity to deviate from the geometric center of the object, which is extremely dangerous when the vehicle is running at high speed.

Embodiment Construction

[0067] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0068] like figure 1 As shown, a vehicle three-dimensional centroid detection method includes the following steps:

[0069] Step 1: Aiming at the problem of the stability of the vehicle affected by the position of the center of mass during motion, deduce the formula for calculating the center of gravity of complex geometry in principle, and establish a mathematical model.

[0070] The derivation process of the mathematical model in step 1 is:

[0071] like figure 2 As shown, remember that the contact points between the four wheels of the vehicle and the ground are a, b, c, d, assuming that point E is the three-dimensional position point of the center of mass of the vehicle object, the direction of b and c is the coordinate X axis, and the direction of a and b is is the coordinate Y-axis, and the three-dimensional Cartesian coordinate system of the v...

Abstract

The invention discloses a method for detecting a three-dimensional center of mass of a vehicle, comprising the following steps: aiming at the problem of the stability of the vehicle being affected by the position of the center of mass during motion, inferring the calculation formula of the center of gravity of a complex geometric body in principle, and establishing a mathematical model; according to the established mathematical model , take the contact points between the four wheels of the vehicle and the ground as the measuring point, establish the coordinate position with the measuring point, detect the force at the force point, and use the principle of the moment vector of the three-dimensional coordinate as "0", and introduce the calculation formula of the three-dimensional coordinate position of the center of gravity And establish the center of mass detection model, give the force measuring point and coordinate value; use the sensor to collect various parameters in the running of the vehicle, and transmit the various parameters to the computer at the same time after the collection, the computer detects the center of mass position and the collected data according to the center of mass detection model. Various parameters output control signals to adjust the various components of the vehicle's running operation to realize the steady state driving of the vehicle. The invention can basically meet the requirements of actual use and design goals.

Description

technical field [0001] The invention relates to a method for detecting a three-dimensional center of mass of a vehicle. Background technique [0002] At present, the speed increase of highway vehicles has higher and higher requirements for vehicle dynamic stability and stability. How to control and judge and ensure a reasonable center of gravity in design, manufacture, and actual vehicle operation is very important. . The design of the vehicle, the load, and the high-speed centrifugal curve movement will all form an asymmetric structure and uneven quality. These factors will cause the center of gravity to deviate from the geometric center of the object, which is extremely dangerous when the vehicle is running at high speed. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a vehicle three-dimensional centroid detection method with simple algorithm and reliable detection. [0004] The technical solution of th...
