VEHICLE STEERING DEVICE

摘要

A vehicle steering device (1) having a steering actuator (14) for steering wheels (5) to be steered according to operation of a steering member (2), a transmission mechanism (18) including cables (22, 23), a connection mechanism (19) for allowing and interrupting mechanical connection between the steering member (2) and the wheels (5), and control unit (9). When the steering actuator (14) is normal, the control unit (9) causes the connection mechanism (19) to release mechanical connection between the steering member (2) and the wheels (5) and drives and controls the steering actuator (14) according to operation of the steering member (2). The control unit (9) includes an abnormality detection section (29) for detecting, when the steering actuator (14) is normal, an abnormality of the transmission mechanism (18) based on a load on the steering actuator (14).
