Abstract:
A steering control apparatus for a vehicle, comprising: an actuator that drives a steering mechanism capable of steering wheels of the vehicle; a torque detector that detects steering torque input by a driver; a travel route recognizing section that recognizes a travel route of the vehicle; and a steering assistance section that outputs a signal that drives the actuator such that the vehicle travels along the travel route recognized by the travel route recognizing section,wherein the steering control apparatus for a vehicle is provided with: a steering torque change state calculation section that calculates a moving integral value of a squared value of an amount of change in the steering torque detected by the torque detector; a driving intention determination section that determines whether there has been a decrease in the driving intention of the driver based on a result of a calculation by the steering torque change state calculation section; a notification section that outputs a warning to the driver; and an execution section that executes at least one of stopping the driving of the actuator by the steering assistance section and outputting the warning by the notification section when it is determined by the driving intention determination section that there has been a decrease in the driving intention.
