Vehicle Software Update Cancellation With Split Error Handling

The patent segments cancellation reasons into two categories: server-side errors (first errors) and vehicle-side errors (second errors). The server handles notification for first errors, while the vehicle autonomously handles notification for second errors. This segmentation reduces server management cost by having the vehicle manage its own error notifications while ensuring complete user notification through dual-responsibility coverage.

The patent implements self-service by enabling the vehicle to autonomously determine and notify users about second errors (vehicle-side errors) without server intervention. The vehicle checks its own error conditions and displays appropriate messages to users, reducing server processing power requirements while maintaining notification reliability through the vehicle's autonomous error handling capability.

The patent segments error determination responsibilities based on error origin: the server determines first errors (server-side issues) while the vehicle determines second errors (vehicle-side issues). This segmentation ensures notification accuracy is maintained for each party's errors while reducing overall server management cost, as the vehicle independently manages its own error notifications without requiring server involvement.

The patent implements self-service error notification where the vehicle autonomously notifies users about second errors without requiring wireless communication with the server. This ensures system availability is maintained in poor connectivity environments, as the vehicle can independently determine and communicate vehicle-side errors to users through local display devices, while server coordination remains optional for first error notifications.
