Method of making tuning map for controlling device of vehicle

Abstract

A method of making a tuning map for a vehicle device includes deriving performance parameters of the vehicle device in a new vehicle and setting a target tuning performance. A pre-tuning map is established by building an interpretation model of the new vehicle including an interpretation model and a control model of the vehicle device, and tuning parameters, which satisfy the target tuning performance, are set using the performance parameters through interpretation of the models. The pre-tuning map is applied to a control logic of the vehicle device for an actual vehicle which includes the vehicle device mounted therein, and the actual vehicle tuning is performed. Whether actual vehicle performance satisfy a preset target performance after tuning the actual vehicle is evaluated, and the tuning map is finalized when the target tuning performance is satisfied.

Description

technical field [0001] The invention relates to a method of obtaining a tuning map. More specifically, the present invention relates to such a method of obtaining a tuning map, for example, of a motor drive power steering (MDPS), for controlling electronic devices in a vehicle to provide a verified Pre-tuned maps. Background technique [0002] For convenient and safe driving, a vehicle includes many electronic components and equipment, such as engine and transmission, steering equipment, braking equipment, etc. [0003] As the electronics industry has significantly developed in recent years, a large number of electronic devices are mounted on vehicles, for example, Electric Power Steering (MDPS) for assisting steering power using rotational torque of a motor. [0004] Based on the tuning map reflecting the control logic, the motor of the MDPS is controlled to determine the MDPS torque by using the steering input value according to the driver's manipulation of the steering ...

AI Technical Summary

Problems solved by technology

[0013] Thus, the process of modifying the tuning map (retuning) to meet the target performance cannot be repeated during the tuning process of the actual vehicle, and it is impossible to achieve the optimal tuning map

[0014] Also, see figure 2 , the target performance may not be achieved even after repeated tuning for the actual vehicle, since the tuning map for an existing vehicle may not have comparable system properties, and the initial performance (when applying the tune map of a mass-produced vehicle) may not be very good

[0015] In addition, the existing tuning process relies heavily on the operator to obtain the best tuning to meet the target performance
