*This abstract for appeared for patent application  number 18207974 Titled 'VEHICLE PROGRAM UPDATE SYSTEM AND VEHICLE PROGRAM UPDATE METHOD'

==Simplified Explanation==

This abstract describes a system and method for updating the software program that controls a vehicle. The update is done wirelessly from an external device. After the update is completed, the system checks if the updated program is functioning normally. If it is not, the vehicle switches to a "limp home" mode where it can still be driven using the vehicle's power source, but without relying on the updated program for control.


==Original Abstract Submitted==

A vehicle program update system and a vehicle program update method are provided which update a vehicle program that is used to control a vehicle by an on-board control device mounted on the vehicle to an update program received by the vehicle from an external device separate from the vehicle via wireless communication. When the update of the vehicle program is completed, determination is made whether the updated vehicle program is normal. When determination is made that the updated vehicle program is not normal, control of the vehicle is switched from control that is performed by the on-board control device using the vehicle program to limp home control for performing a limp home operation in which the vehicle travels using a driving force from a vehicle driving force source without being controlled by the on-board control device.
