  • COAST CONTROL FOR ELECTRIFIED VEHICLES TO COMPENSATE FOR DOWNHILL GRADES WITH VARIABLE LOAD
    Publication number: 20260274082
    Abstract: A coast control system and method for a battery electric vehicle (BEV) include determining a minimum pedal torque for the BEV corresponding to a minimum accelerator pedal position to maintain the BEV traveling at a given speed on a flat surface and carrying a nominal load and, based thereon, calculating maximum acceleration thresholds for the BEV for entry to and exit from a coast control feature of the BEV, respectively. When a set of preconditions for the coast control feature are satisfied and a vehicle acceleration of the BEV is greater than the maximum acceleration threshold for entry into the coast control feature, the coast control feature is executed by decreasing a driver torque request for the BEV and the minimum pedal torque by a coast control offset.
