Problems solved by technology

Restricted by working conditions and environment, the calibration process takes a long time and the calibration cost is high
Taking the braking system in vehicles as an example, it usually takes a long calibration process of "two summers and one winter" to complete the parameter calibration in the braking system, which seriously affects the calibration efficiency

Abstract

The invention provides a parameter calibration method and device. The parameter calibration method and device can be applied to vehicles such as intelligent vehicles, new energy vehicles, connected vehicles and intelligent driving vehicles. The method comprises the steps of obtaining an evaluation result of a parameter combination of a plurality of devices, wherein the evaluation result of the parameter combination of the plurality of devices is obtained by performing a calibration test on the plurality of devices in a first time period based on the parameter combination of the plurality of devices; and obtaining at least one adjusted parameter combination according to the evaluation result of the parameter combinations of the plurality of devices. According to the scheme, the parameter calibration efficiency can be improved.

Description

technical field [0001] The present application relates to the field of data processing, and more specifically, to a method and device for parameter calibration. Background technique [0002] Parameter calibration refers to the process of finding a set of parameters that are applicable under various conditions, for example, under different hardware conditions or different environmental conditions. Taking vehicle calibration as an example, vehicle calibration refers to the control of the components in the control software in order to obtain satisfactory vehicle performance, meet the requirements of the vehicle before leaving the factory, and meet relevant national standards after the controller hardware, control software, and related sensors are determined. The process of parameter optimization. [0003] Vehicle calibration results are an important factor affecting vehicle-related performance. Before the vehicle goes on the market, it is usually calibrated by an experienced ...
