VEHICLE ONE PEDAL DRIVE GRADE COMPENSATION SYSTEM
DRIVE
March 31, 2022
A vehicle includes a gear selector that selects between a drive and reverse gear. The gear selected defines an intended travel direction. The vehicle also includes a controller that, responsive to user input, activates a one-pedal drive system, and responsive to detecting the vehicle is rolling back for more than a predefined time period, a feedforward road grade compensation torque being opposite to the intended travel direction and having a magnitude greater than a feedforward threshold, and a feedback data noise compensation torque in the intended travel direction having a magnitude greater than a feedback threshold, reduces the maximum magnitude of the feedforward road grade compensation torque to a predefined value throughout a current key cycle for the vehicle.
