Abstract

The invention discloses a method and system for calculating the total mass of a vehicle. The method comprises the steps of obtaining first engine output powers respectively corresponding to multiple running speeds of the vehicle in a slope-free constant-speed running state to form a first two dimensional table, obtaining second engine output powers respectively corresponding to multiple running speeds of the vehicle in an accelerated or up-hill running state to form a second two dimensional table, and calculating the total mass of the vehicle according to the first two dimensional table and the second two dimensional table. The accuracy and confidence level of the total mass of the vehicle can be improved, and the running economy and safety of the vehicle can be also improved.

Description

technical field [0001] The invention relates to the field of mass calculation, in particular to a method and system for calculating the total mass of a vehicle. Background technique [0002] At present, more and more cargo vehicles begin to apply advanced electronic control systems, such as electronic braking system (EBS), electronic stability system (ESP), etc., these systems set the total weight of the vehicle as a control parameter, and at the same time The total mass of the vehicle is also an important parameter to consider when encountering multiple shift schedules such as multi-power multi-map engines and automatic transmissions. In general, each electronic system sets the total mass of the vehicle as a certain value parameter. However, the current situation is that there is a large change in the total vehicle mass of a cargo vehicle between no-load and full load, and it is difficult to predict in advance. If the actual total vehicle mass is very different from the to...
