Abstract
A method includes automatically monitoring a path in proximity to a vehicle to detect an abrupt grade change along the path and ahead of the vehicle. The grade change is determined to be abrupt depending on a predetermined threshold of a minimum change in grade height. Upon receiving, by processor circuitry forming at least one processor, indication that an abrupt grade change exists, the method determines a time or distance or both from a position of the vehicle to the abrupt change. The method then determines, by the processor, a target speed the vehicle is to use to travel over the abrupt grade change using predetermined correlations between a target speed of the vehicle and an indicator of expected comfort of an occupant of the vehicle as the vehicle travels over the abrupt grade change. The vehicle is decelerated to the target speed to drive over the abrupt grade change.
