Abstract

The invention provides a system of modeling an anti-lock brake system (ABS) controller of a vehicle. The system includes: a vehicle speed estimation network configured to estimate a vehicle speed through machine learning using wheel speed data of each of a plurality of wheels of the vehicle; a wheel speed state estimation network configured to estimate a time series characteristic of the wheel speed through machine learning using information on the wheel speed data and information on whether a brake pedal is depressed; and a classification network configured to estimate a braking mode for controlling an increase, a decrease, or steady state of a braking pressure of each wheel through machine learning using speed estimation data of the vehicle estimated by the vehicle speed estimation network and time series characteristic estimation data of the wheel speed estimated by the wheel speed state estimation network.

Description

technical field [0001] The present invention relates to a system for modeling an anti-lock braking system (ABS) controller of a vehicle, and more particularly, to a system for modeling an ABS controller comprising a deep learning network implemented by machine learning, This machine learning is performed based on the input / output data of the vehicle's ABS controller applying a proprietary control algorithm. Background technique [0002] An integrated virtual vehicle performance analysis system has been constructed, which combines vehicle dynamics model, system model and control model for vehicle development and testing. The integrated virtual vehicle performance analysis system can detect the vehicle's control performance without changing the resources applied to the actual vehicle, and can significantly reduce the time and / or cost of vehicle development. [0003] However, the controllers used to control the various components of the vehicle are mainly programmed by the man...
