System and method for controlling inter-vehicle distance to preceding vehicle for automotive vehicle equipped with the system and method
First Claim
1. A system for an automotive vehicle equipped with the system and defined as a system vehicle, comprising:
- a first detector for detecting an inter-vehicle distance from the system vehicle to a preceding vehicle traveling ahead of the system vehicle;
a second detector for detecting a velocity of the system vehicle;
an inter-vehicle distance controller for calculating a target value of the velocity of the system vehicle to make a detected value of the inter-vehicle distance coincident with the target value of the inter-vehicle distance;
a system vehicle velocity controller for calculating a target value of a driving-and-braking force applied to the system vehicle to make a detected value of the system vehicle velocity coincident with the target value of the velocity of the system vehicle;
a drive controller for drivingly controlling a prime mover of the system vehicle and a transmission thereof in accordance with the target value of the driving-and-braking force;
a maximum deceleration force estimator for estimating a maximum deceleration force according to the target value of the velocity of the system vehicle and a shift position of the transmission of the system vehicle;
a relative velocity calculator for calculating a relative velocity of the system vehicle to the preceding vehicle on the basis of the detected value of the inter-vehicle distance; and
a shift position determinator for determining the shift position of the transmission on the basis of the target value of the driving-and-braking force, the estimated maximum deceleration force, and the relative velocity.
