Abstract: Systems and methods for adjusting a height of an implement mounted on a body of a vehicle as the vehicle travels over a terrain are provided. Sensor data is received from a set of sensors disposed on the vehicle. A trajectory associated with the vehicle is determined based on the received sensor data. A profile of the terrain is estimated based on the determined trajectory associated with the vehicle. A ditch is detected in the terrain and compensation values for adjusting the height of the implement are determined based on the estimated profile of the terrain to compensate for the detected ditch. One or more control signals are transmitted to one or more actuators for adjusting the height of the implement based on the determined compensation values.

Abstract: Systems and methods for determining a swing angle of a swing boom of a vehicle are provided. Sensor data is received from sensors disposed on a swing boom and a body of a vehicle. It is determined whether the swing boom is static or moving relative to the body based on the sensor data. In response to determining that the swing boom is static, the received sensor data is corrected based on an observed swing angle and an estimated swing angle is calculated based on the corrected sensor data. In response to determining that the swing boom is moving, the estimated swing angle is calculated based on the received sensor data. The estimated swing angle is output.
