Abstract
A method for a vehicle maintenance/repair detection system is described. The method includes logging, in a vehicle log, advanced driver assistance system (ADAS) actuations during a road trip. The method also includes analyzing the vehicle log to identify the ADAS actuations during the road trip to correct a trajectory of an ego vehicle. The method further includes analyzing a correction of the trajectory of the ego vehicle to determine a direction of the ADAS actuations to correct the trajectory of the ego vehicle. The method also includes determining a maintenance/repair for the ego vehicle according to the direction and a frequency of the ADAS actuations to correct the trajectory of the ego vehicle.
Claims16
A method for a vehicle maintenance/repair detection system, the method comprising:
- logging, in a vehicle log, advanced driver assistance system (ADAS) actuations during a road trip;
- analyzing the vehicle log to identify the ADAS actuations during the road trip that correct a trajectory of an ego vehicle as trajectory corrections;
- analyzing the trajectory corrections of the ego vehicle to determine a direction of the ADAS actuations to perform the trajectory corrections of the ego vehicle;
- determining a maintenance/repair for the ego vehicle according to the direction and a frequency of the ADAS actuations to perform the trajectory corrections of the ego vehicle;
- monitoring torque inputs to a steering wheel by the driver;
- and
- determining a slope of a roadway on which the ego vehicle is traveling, in which determining the maintenance/repair for the ego vehicle comprises notifying the driver of the detected maintenance/repair when the slope of the roadway is flat.
A non-transitory computer-readable medium having program code recorded thereon for a vehicle maintenance/repair detection system, the program code being executed by a processor and comprising:
- program code to log, in a vehicle log, advanced driver assistance system (ADAS) actuations during a road trip;
- program code to analyze the vehicle log to identify the ADAS actuations during the road trip that correct a trajectory of an ego vehicle as trajectory corrections;
- program code to analyze each of the trajectory corrections of the ego vehicle to determine a direction of the ADAS actuations to perform the trajectory corrections of the ego vehicle;
- program code to determine a maintenance/repair for the ego vehicle according to the direction and a frequency of the ADAS actuations to perform the trajectory corrections of the ego vehicle;
- program code to monitor torque inputs to a steering wheel by the driver;
- and
- program code to determine a slope of a roadway on which the ego vehicle is traveling, in which the program code to determine the maintenance/repair for the ego vehicle comprises program code to notify the driver of the detected maintenance/repair when the slope of the roadway is flat.
A vehicle maintenance/repair detection system, the system comprising:
- a vehicle log module to log, in a vehicle log, advanced driver assistance system (ADAS) actuations during a road trip;
- a trajectory correction identification module to analyze the vehicle log to identify the ADAS actuations during the road trip that correct a trajectory of an ego vehicle as trajectory corrections;
- a direction and frequency module to analyze each correction of the trajectory of the ego vehicle to determine a direction of the ADAS actuations to perform the trajectory corrections of the ego vehicle;
- and
- a maintenance/repair module to determine a maintenance/repair for the ego vehicle according to the direction and a frequency of the ADAS actuations to perform the trajectory corrections of the ego vehicle, to monitor torque inputs to a steering wheel by the driver, and to determine a slope of a roadway on which the ego vehicle is traveling, in which to determine the maintenance/repair for the ego vehicle the maintenance/repair module is further to notify the driver of the detected maintenance/repair when the slope of the roadway is flat.
