Abstract

An embodiment of the invention provides a vehicle load state recognition method and system. The method comprises the steps as follows: acquiring gear information, acceleration and the engine torque percentage sum of a to-be-tested vehicle in an acceleration interval; acquiring load state thresholds according to the gear information of the to-be-tested vehicle in the acceleration interval, whereinthe load state thresholds comprise a heavy load threshold and a no-load threshold; calculating the ratio of the engine torque percentage sum to the acceleration of the to-be-tested vehicle in the acceleration interval; comparing the ratio with the load state thresholds to obtain the load state of the to-be-tested vehicle. By means of the method and the system, no sensor is required, and the cost and complexity of recognition of the vehicle load state can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicles, and in particular, to a method and system for identifying a load state of a vehicle. Background technique [0002] In order to effectively solve the spilling problem of the muck truck, it is required to cover the muck truck with a tarpaulin when it is fully loaded. For a muck truck that is not covered with a tarpaulin when fully loaded, it will be speed-limited. For this purpose, the current loading status of the vehicle needs to be known. [0003] At present, there are two common methods. The first one is: by installing a load cell to obtain the current cargo weight of the vehicle, so as to judge whether the current vehicle is fully loaded; the other is: to collect video images of the vehicle body, through Video analysis to get whether the current vehicle is fully loaded. [0004] However, the above method has the following problems: first, the cost is high; second,...
