Abstract
A vehicle and vehicle system are provided with a controller that is configured to generate output indicative of a vehicle mass estimation. The vehicle mass estimation is based on a longitudinal acceleration and a wheel torque when at least one of the longitudinal acceleration, a vehicle speed and a yaw rate indicate an occurrence of a qualified event. The controller is further configured to generate output indicative of a dynamic road gradient estimation based on the vehicle speed, the wheel torque and the vehicle mass estimation.
