Abstract:
In a steering assistance apparatus mounted in a vehicle, a steering input device and a turning device differentiate at a transmission ratio that is a ratio of an amount of change in the turning angle to an amount of change in the steering angle. A turning device actuator actuates the turning device. A controller executes an automatic steering mode, in which the controller determines the turning angle based on at least one of a travel condition and travel path information of the vehicle and controls the turning device actuator so as to achieve the determined turning angle. If detecting an input variation from the steering input device during execution of the automatic steering mode, the controller changes the transmission ratio to a value less than the transmission ratio in the automatic steering mode and prioritizes a manual steering mode over the automatic steering mode.
