Abstract

The invention provides a dynamic weighing correction method of a vehicle weighing module. The method is used for correcting vehicle weight detected when a vehicle runs. Firstly, a vehicle-mounted weighing module provided with a gyroscope sensor, a storage unit and a processing unit is provided, installed on the vehicle and used for detecting the weight of the vehicle, an angular variation correction coefficient A and an acceleration correction coefficient B are calculated through the processing unit according to a deviation angle theta O, the lateral force coefficient kx in the X-axis direction, the lateral force coefficient ky in the Y-axis direction, acceleration components ax, ay and az, gravity acceleration g and the included angle theta, detection weight S of the vehicle at a certain dynamic moment is obtained through the vehicle-mounted weighing module, and the actual weight G of the vehicle is calculated through the formula satisfying G=S / (A*B). The dynamic weighing correction method of the vehicle weighing module is simple in computation principle, high in operating speed and high in detection precision.

Description

technical field

[0001] The invention relates to a dynamic weighing correction method of a vehicle weighing module. Background technique

[0002] With the rapid growth of the logistics industry, there are more and more cases of vehicle overloading and overloading. The state has adopted a series of measures in response to this situation, such as charging by weight. The premise of taking these measures is that the weight of the vehicle can be accurately detected.

[0003] At present, the well-known measurement in the field of vehicle weighing mostly adopts the method of separating weighing and driving state, that is, the method of measuring when the vehicle is stationary, and is mainly applied to a certain extent on specific engineering vehicles. However, because the load weighing of the vehicle in the dynamic running process is affected by many factors, such as acceleration, driving gradient, etc., the existing measurement methods cannot solve it well.

Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with specific embodiments.

[0023] The dynamic weighing correction method of the vehicle-mounted weighing module of the present invention is used to correct the vehicle weight detected when the vehicle is driving on a slope, and its implementation steps are as follows:

[0024] Firstly, a vehicle-mounted weighing module with a gyroscope sensor, a storage unit and a processing unit is provided, the vehicle-mounted weighing module is arranged on the vehicle to detect the weight of the vehicle, and the weight of the vehicle is set when the vehicle is in a horizontal position. The forward / backward direction is the X axis, the left and right direction is the Y axis, and the up and down direction is the Z axis. The storage unit stores the deviation angle Φ between the vertical direction of the gyro sensor and t...
