Description

technical field [0001] The invention relates to a method for optimizing engine calibration parameters based on simulation training. In a simulation environment based on machine learning technology, the vehicle exhaust emission process is simulated to obtain an optimization strategy for engine calibration parameters, which belongs to the field of industrial intelligent manufacturing. Background technique [0002] The vehicle engine calibration process adjusts the parameters of each control module in the electronic control unit to make the exhaust gas emitted during driving meet the national emission standards. After the engine, control strategy, and peripheral devices are determined, in order to make the vehicle's emissions meet the national standards, it is necessary to find out the parameters of the engine under working conditions. The general calibration process is first to make the engine work normally through the bench test, and then get the initial set of parameters. N...
