REDUNDANT STEER-BY-WIRE DEVICE, REDUNDANT STEER-BY-WIRE SYSTEM ARCHITECTURE AND DRIVING APPARATUS

摘要

Provided is a redundant steer-by-wire device. The redundant steer-by-wire device comprises a steering control mechanism (a), a steering actuator mechanism (b) and a comprehensive controller (13), wherein the steering control mechanism (a) is connected to the comprehensive controller (13) by means of a two-path CAN line, and the steering actuator mechanism (b) is connected to the comprehensive controller (13) by means of the two-path CAN line. The redundant steer-by-wire system architecture comprises a redundant steer-by-wire device, and a first whole vehicle power supply (22), a second whole vehicle power supply (25) and a whole vehicle central gateway (18) which are connected to the redundant steer-by-wire device. The driving apparatus comprises a redundant steer-by-wire system architecture. The technical effects of the redundant steer-by-wire device having a smaller arrangement space, higher control precision, higher safety and better synchronism and the whole system having a redundant architecture are achieved.
