Title:
STEERING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/030419
Kind Code:
A1
Abstract:
A first circuit (68) energizes a steering assist actuator (800). A second circuit (67) energizes a lock actuator (710) that drives a lock device (20) to perform a locking operation or an unlocking operation. The first circuit (68) and the second circuit (67) are provided inside the same housing (600). Defining a leg to be a pair of high-potential-side and low-potential-side switching elements connected in series in the first circuit (68) and the second circuit (67), the first circuit (68) and the second circuit (67) form an integrated power conversion circuit (60) sharing a single leg. A control unit (30) causes the steering assist actuator (800) and the lock actuator (710) to operate simultaneously so as to support the locking operation or unlocking operation by the lock device (20) according to the rotation of a steering wheel (91).
