Abstract:
A vehicular velocity controlling apparatus for an automotive vehicle, comprising:inter-vehicle distance detecting means for detecting an inter-vehicle distance from the vehicle to a preceding vehicle which is running ahead of the vehicle;relative velocity detecting means for detecting a relative velocity of the vehicle to the preceding vehicle;vehicular velocity detecting means for detecting a vehicular velocity of the vehicle;inter-vehicle distance controlling means for calculating a target value of the vehicular velocity to make a detected value of the inter-vehicle distance substantially equal to a target value of the inter-vehicle distance on the basis of the detected value of the inter-vehicle distance and a detected value of the vehicular velocity;vehicular velocity controlling means for controlling the vehicular velocity to make the detected value of the vehicular velocity substantially equal to the target value of the vehicular velocity;vehicular turning magnitude detecting means for detecting a magnitude of a turning of the vehicle;correction coefficient calculating means for calculating a correction coefficient of the magnitude of the vehicular turning in accordance with the detected value of the vehicular velocity; andtarget vehicular velocity correcting means for correcting the target value of the vehicular velocity on the basis of the turning magnitude correction coefficient by which the detected value of the turning magnitude is corrected.
