Road roughness system for a vehicle

A road roughness system for a vehicle, the road roughness system comprising:

• data processing hardware;
• and
• memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
• receiving, at a road roughness algorithm, a plurality of sensor data from a plurality of sensors of the vehicle, the sensor data including wheel data and ride height data;
• determining, via the road roughness algorithm, the wheel data exceeds a wheel threshold and a severity level associated with the wheel data exceeds the wheel threshold;
• executing, based on the wheel data exceeding the wheel threshold and the severity level of the wheel data, a wheel flag, the wheel flag including one or more wheel identifications (IDs), the road roughness algorithm being configured to identify a wheel of the vehicle based on the wheel ID;
• determining, based on the wheel flag, the ride height data exceeds a ride height threshold;
• executing, based on the ride height data exceeding the ride height threshold, a ride height flag;
• determining, based on the wheel flag and the ride height flag, a time duration of a wheel jerk of the wheel data exceeds a time threshold;
• identifying, via the road roughness algorithm, a change in initial measurement units (IMU) that exceed an IMU threshold;
• executing, based on the change in the IMU exceeding the IMU threshold, an IMU flag;
• adjusting, based on the IMU flag, one or more parameters of the road roughness algorithm;
• and
• fusing, via the road roughness algorithm, the wheel flag, the ride height flag, and the IMU flag to define a road anomaly;
• mitigating the road anomaly by reducing a speed of the vehicle;
• and
• executing, via the road roughness algorithm, a control and mitigation function.
