Patent ID: 7844384

Claim:
A vehicular traveling control apparatus, comprising: a vehicular forward substance detecting section that detects a forward substance located in a forward direction of the vehicle; a vehicular travel controlling section that performs a vehicular travel control on the basis of a relative positional relationship between the forward substance detected by the vehicular forward substance detecting section and the vehicle; an impulse detecting section that detects such an impulse that a detection range of the vehicular forward substance detecting section is varied has been applied to the vehicular forward substance detecting section; wherein the vehicular travel controlling section estimates an optical axis deviation quantity of the detection range of the vehicular forward substance detecting section when the impulse detecting section detects that the impulse has been applied to the forward substance detecting section; and a running control varying section that varies a control method of the vehicular travel controlling section in accordance with the optical axis deviation quantity estimated by the vehicular travel controlling section.
