Method and system for controlling anti-jerk of vehicle

摘要

A method and system for controlling anti-jerk in order to reduce vibration of a vehicle is provided. More specifically, a rotation speed (ωm) of a driving source device of the vehicle is received and a speed (ωlwh, ωrwh) of a left wheel and a right wheel connected to the driving source device is detected by a sensor respectively. Then, a controller, which receives this data, calculates an average speed (ωfwh) based on the detected left and right wheel speeds, produces a virtual speed through interpolation of the detected left and right wheel speeds and the average speed based on a predetermined sampling value, and calculates a model speed (ωref) based on the detected left and right wheel speeds, the average speed, the virtual speed, and a final gear ratio (γj; where j is the number of the gear) considering a final reduction gear ratio (FGR) and a current gear of the vehicle.

1. A method of controlling anti-jerk of a vehicle, comprising:
receiving, at a controller, a rotation speed (ωm) of a driving source device of the vehicle; detecting, by a sensor, a speed (ωlwh, ωrwh) of a left wheel and a right wheel connected to the driving source device, respectively; calculating, by the controller, an average speed (ωfwh) based on the detected left and right wheel speeds; producing, by the controller, a virtual speed through interpolation of the detected left and right wheel speeds and the average speed based on a predetermined sampling value; calculating, by the controller, a model speed (ωref) based on the detected left and right wheel speeds, the average speed, the virtual speed, and a final gear ratio (γj; where j is the number of the gear) considering a final reduction gear ratio (FGR) and a current gear of the vehicle; subtracting, by the controller, the calculated model speed (ωref) from the rotation speed (ωm) of the driving source device in order to calculate vibrating components for anti-jerk controlling; and controlling, by the controller, the driving source device to generate anti-jerk torque using the calculated vibrating components.
