Vehicle steering system

摘要

A brake application speed (19) is compared (S2) with a speed threshold value (K) so as to judge whether or not a braking operation being performed is an emergency braking operation. If not the emergency braking operation, an automatic parking mode is held (b). When the emergency braking operation is in effect, control information related to a state of an automatic parking control then is stored in a control information storage section (S3), and the automatic parking control is cancelled (S4). Thereafter, when a steering operation (S5) or a gearshift operation (S6) is performed before a cancellation of application of the brake is detected (S7), the process is ended, and the control mode is held in an assist mode (C). When the application of the brake is cancelled with neither the steering operation nor the gearshift operation performed, the control information is read in (S8) so as to resume the automatic parking control (S9).
