Remote update computing system and method for vehicle controller software

Abstract

The invention discloses a remote update calculation system and method for vehicle controller software, comprising: a compatibility relationship matrix module for establishing a compatibility relationship matrix table; a real-time monitoring service module for actively monitoring vehicle position information, fuel information and Network health status, when the network health status is good, the information collection service module is started; the information service collection module is used to obtain all hardware identification codes and hardware version information in the current state of the vehicle, as well as all software identification codes and software version information; version update active calculation The service module calculates the software upgradeable version combination according to the obtained hardware identification code, hardware version information, software identification code and software version information, combined with the compatibility relationship matrix table; the active push service module pushes the calculated software upgradeable version combination to the vehicle end. The invention reduces the risk of safety loopholes and software failures caused by the inability to update the controller software.

Description

technical field [0001] The invention belongs to the software update technology of automobiles, and in particular relates to a remote update computing system and method for vehicle controller software. Background technique [0002] At present, the on-board controller software cannot be updated or a single update method is used in part, that is, the controller software of the car after the production line cannot be updated, or a single controller can be updated through a large-scale recall, but a single controller update is of great importance. The degree of influence of other controller functions cannot be quickly and effectively identified, resulting in a sharp increase in functional safety risks, after-sales costs, and recall costs caused by software problems in the car, and cannot meet the needs of customization and market orientation in a timely manner, which is not conducive to the improvement of enterprise service capabilities and User innovation experience.
