Abstract: System for calibrating a torque control function of a vehicle having a driveline, wherein the torque control function controls an input torque applied to the driveline, the system comprising a mathematical representation configured to simulate in the time domain vehicle and/or driveline dynamics in response to an applied input torque, the mathematical representation representing at least driveline backlash, the system being configured to: transform the mathematical representation into a frequency domain, define a desired response of the transformed mathematical representation in the frequency domain, translate said desired response of the mathematical representation into a required input torque in the time domain, and calibrate the torque control function based on the required input torque.

Abstract: The invention relates to a system (10) for calibrating a torque control function of a vehicle having a driveline, wherein the torque control function controls an input torque applied to the driveline. The system comprises a mathematical representation (f(t)) configured to simulate in the time domain vehicle and/or driveline dynamics in response to an applied input torque. The system is configured to: • - transform ( SI) the mathematical representation (f(t)) into a frequency domain (F(s)), • - define (S2) a desired response (Gx(s))of the transformed mathematical representation in the frequency domain (F(s)), • - translate (S3) said desired response of the mathematical representation into a required input torque in the time domain, and • - calibrate (S4) the torque control function based on the required input torque. The invention further relates to a method of calibrating a torque control function.
