ELECTRONIC CONTROL DEVICE, REPROGRAM EXECUTION METHOD, AND NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18304390 titled 'ELECTRONIC CONTROL DEVICE, REPROGRAM EXECUTION METHOD, AND NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM
Simplified Explanation
- The patent application describes an electronic control device that can reprogram an electronic control unit in a vehicle. - The device includes a manifest file acquisition unit, an update program acquisition unit, and a reprogram execution unit. - The reprogram execution unit instructs the electronic control unit to write the update program based on the machine state and function group defined in the manifest file. - The manifest file defines a normal state and a reprogram state as machine states conforming to a predetermined in-vehicle software platform standard specification. - The manifest file also defines a first group of reprogrammable applications that can be updated while the vehicle drive mechanism is running, and a second group of applications that are not related to reprogramming. - Each group in the manifest file has an activation state and a stop state.
Original Abstract Submitted
An electronic control device includes: a manifest file acquisition unit; an update program acquisition unit; and a reprogram execution unit that executes reprogramming according to a machine state and a function group defined in a manifest file by instructing an electronic control unit as a reprogram target device to write the update program. The manifest file defines a normal state and a reprogram state as machine states conforming to a predetermined in-vehicle software platform standard specification; a first group to which a reprogrammable application while a vehicle drive mechanism is running belongs as a function group conforming to the specification; a second group to which an application not relating to the reprogramming belongs; and an activation state and a stop state in each of the first group and the second group.
