GRADE SEVERITY DETECTION

An apparatus for grade severity detection in a motorized vehicle includes a first sensor and a second sensor that provides data to a controller. The first sensor is configured to generate motion data indicative of at least one wheel of the motorized vehicle. The second sensor generate data, which is indicative of torque for at least one wheel of the motorized vehicle. The controller is configured to calculate a pitch of the motorized vehicle based on the torque data and one or more acceleration values derived from the position data and configured to perform a comparison of the calculated pitch to a pitch threshold. A grade severity message is generated based on the comparison.
