Title:
ステアバイワイヤの操舵入力装置
Document Type and Number:
Japanese Patent JP7204959
Kind Code:
B2
Abstract:
A steering input device for steer-by-wire, according to the present invention, includes a steering shaft that is mechanically separated from a steered wheel, a reaction force motor that applies a steering load to the steering shaft, a lock mechanism that regulates rotation of the steering shaft, a steering amount sensor that detects an operation amount of the steering shaft and outputs an operation amount signal, and a controller. The controller increases the reaction torque generated by the reaction force motor after the starting switch of the vehicle is switched to an OFF state, and after the reaction torque is increased, switches the lock mechanism to a locked state. Thereby, it is possible to suppress an uncomfortable sensation of the driver in steering, while suppressing occurrence of a phase shift between the steering wheel and the steered wheel when the starting switch of the vehicle is switched to the OFF state.
