Abstract

The invention discloses a vehicle load measuring method and device. The method comprises the following steps of: setting a first parameter of a to-be-measured vehicle according to the model of the to-be-measured vehicle; controlling the vehicle speed of the to-be-detected vehicle to reach a preset vehicle speed interval, obtaining a message from a vehicle-mounted CAN bus according to a preset sampling interval, and obtaining a second parameter according to the message; acquiring a third parameter of a road on which the to-be-detected vehicle travels from the vehicle-mounted CAN bus on the basis of a vehicle-mounted electronic map at a preset sampling interval; and performing digital filtering on the second parameter and the third parameter, and combining the second parameter and the third parameter subjected to digital filtering with the first parameter to calculate the load value of the to-be-measured vehicle. According to the vehicle load measuring method and device of the embodiment of the invention, the multiple vehicle-mounted bus data of the to-be-measured vehicle are used as the calculation basis for measuring the load, and multiple times of calibration according to different vehicle types and mounting of strain gauges on vehicle frames for load measurement are not needed. The method and device are suitable for various vehicle types, can improve measurement efficiency, reduce measurement cost and effectively improve the test accuracy of the vehicle load.

Description

technical field [0001] The invention relates to the technical field of load detection, in particular to a vehicle load measurement method and device. Background technique [0002] The current vehicle load measurement is to install the strain gauge near the suspension of the vehicle. Under different load conditions, the strain gauge will produce different deformations, so that its resistance characteristics will change with the load. By connecting the strain gauge to the bridge measurement circuit, to obtain different voltage outputs to represent different load data. However, the existing vehicle load measurement method needs to install strain gauges on the vehicle frame, and the performance of the strain gauges is rapidly degraded or even damaged in an exposed environment, which eventually leads to excessive error or failure to measure the vehicle load. Contents of the invention [0003] The invention provides a vehicle load measuring method and device to solve the proble...
