Vehicle suspension system alignment monitoring

A computer-implemented method for detecting a windy condition, the method comprising:

• receiving, by a processing device, vehicle data and environmental data including a vehicle heading and a steering wheel angle (SWA);
• mitigating, by a processing device, for vehicle and environmental effects;
• calculating, by a processing device, a moving average steering wheel angle (SWA) based at least in part on a steering wheel angle;
• correcting, by the processing device, the SWA for the environmental factors;
• detecting, by the processing device, the windy condition by determining whether the moving average SWA changes with respect to the vehicle heading;
• and
• reporting the windy condition based at least in part on determining that the moving averaged SWA changed with respect to the vehicle heading.

A computer-implemented method for detecting a gusty condition, the method comprising:

• receiving, by a processing device, vehicle data and environmental data including a yaw rate and a steering wheel angle;
• mitigating, by a processing device, for vehicle and environmental effects;
• detecting, by the processing device, the gusty condition by counting a number of times the yaw rate and a yaw acceleration exceed a predefined threshold over a specific period of time when a steering wheel is stable and within a threshold;
• and
• reporting the gusty condition based at least in part on exceeding the threshold.

A computer-implemented method for road crown and grade correction, the method comprising:

• receiving, by a processing device, vehicle data and environmental data including inertial measurement unit (IMU) lateral acceleration data associated with the vehicle;
• estimating, by the processing device, an effect of road crown and grade on a self-aligning torque (SAT) based at least in part on the self-aligning torque (SAT) and the lateral acceleration data;
• and
• generating, by the processing device, a corrected SAT based at least in part on the effect of road crown and grade on the SAT.

A computer-implemented method for misalignment event detection, the method comprising:

• monitoring, by a processing device, a self-aligning torque (SAT) and a steering wheel angle (SWA) of a vehicle;
• detecting, by the processing device, an occurrence of a misalignment event that can cause a misalignment of the vehicle;
• responsive to detecting the occurrence of the misalignment event, determining, by the processing device, whether a misalignment of the vehicle occurred by determining whether at least one of the SAT and the SWA experiences a sudden change;
• and
• reporting the misalignment event based at least in part on determining that at least one of the SAT and the SWA experiences a sudden change.
