Abstract
Speed control techniques include, based on a set of target speed inputs indicative a target speed for an electric motor, determining a set of profiling inputs including (i) the target speed and (ii) a set of desired acceleration calibrations, performing jerk-based profiling based on the set of profiling inputs to determine at least one of an open-loop acceleration command and a profiled target speed, determining a closed-loop torque adjustment based on the profiled target speed and a measured speed of the electric motor, determining an electric motor torque command based on the open-loop acceleration command and the closed-loop torque adjustment, and controlling the electric motor based on the respective electric motor torque command to improve vehicle responsiveness in reaching the target speed.
