AI Technical Summary

Technical Problem

Program updates for vehicle lamp light distribution control using OTA technology risk generating unintended incomplete light distribution patterns due to update failures.

Method used

A vehicle system with an update control unit that manages light distribution control program updates, including a limiting unit to restrict light distribution if updates fail, and a storage unit to revert to a previous state using modification data if necessary.

Benefits of technology

Reduces risks associated with OTA updates by ensuring stable light distribution control, even in the event of update failures, through controlled reversion to a previous state or restriction of light distribution functions.

Abstract

This vehicle system (1) comprises: an update control unit (211) for controlling updating of a light distribution control program (221) using update data (222) acquired via wireless communication; and a restriction unit (212) for restricting light distribution control performed by a light distribution control unit (214), which is capable of controlling the light distribution of a vehicular lighting fixture (200) on the basis of the light distribution control program (221), when updating of the light distribution control program (221) using the update data (222) has failed.
