Abstract
Official abstract text for this publication.
The vehicle fixing control unit fixes the vehicle during the charging of the backup power supply, and the vehicle fixing by the vehicle fixing device is not released regardless of the vehicle fixing release request by the operation of the vehicle fixing device operation switch until the remaining charge amount of the backup power supply reaches the fail-safe executable remaining charge amount determination value set in advance. Thus, when the vehicle travels with the vehicle fixing released, since at least the remaining charge amount is stored up to the remaining charge amount determination value that can be performed in a fail-safe manner enough to operate the steer-by-wire system at the time of starting the vehicle traveling, it is possible to sufficiently function the vehicle steering control device even in an emergency.
First claim
Opening claim text (preview).
What is claimed is: 1 . A steering control device for a vehicle in which a steering wheel and a steered wheel are mechanically separated from each other, a steering angle motor configured to change a steering angle of the steered wheel in response to a steering operation on the steering wheel is controlled using electric power in a main power supply, and a backup power supply configured to back up the main power supply starts to be charged when the vehicle is powered on, the steering control device comprising a vehicle fixing control unit configured to fix the vehicle during charging of the backup power supply, and configured not to terminate fixing of the vehicle regardless of a vehicle fixing termination request before a remaining charge amount of the backup power supply reaches a preset fail-safe executable remaining charge amount determination value.
