Vehicular travel control device |
摘要 |
A vehicular steering control device which comprises a rudder angle varying device which changes a relationship between an operational position of steering wheel operated for steering by a driver and a rudder angle of front wheels; and a rudder angle control device which performs an automatic steering control of the front wheels for a trajectory control of a vehicle by controlling the rudder angle varying device. The rudder angle control device performs a termination control which removes a deviation in the relationship between an operational position and a rudder angle of the front wheels, namely, an N deviation when the automatic steering control is terminated. A speed of removing the N deviation is lowered when a magnitude of a steering operation speed is small, compared to when a magnitude of a steering operation speed is large. |

1. A vehicular steering control device which comprises:
a rudder angle varying device which changes a relationship between an operational position of a steering input device operated for steering by a driver and a rudder angle of steering wheels; and a rudder angle control device which performs an automatic steering control which controls the rudder angle of said steering wheels by controlling said rudder angle varying device; and said rudder angle control device performs a termination control which makes said relationship revert to a standard relationship when said automatic steering control is terminated, wherein said rudder angle control device lowers a speed of making said relationship revert to said standard relationship by reducing a control amount for making said relationship revert to said standard relationship when a magnitude of a steering operation speed is small, compared to when a magnitude of a steering operation speed is large; and said rudder angle control device does not lower a speed of making said relationship revert to said standard relationship when a magnitude of a curvature of a driving lane in front of a vehicle is equal to or smaller than a reference value for a curvature. |
