Recognition result of an objective recognized as a preceding vehicle is analyzed to judge whether this objective is correctly detected as a vehicle or not. A relative acceleration is calculated based on a relative speed corresponding to the objective when analysis result shows properness of this objective as a vehicle. The relative acceleration is set to 0 when analysis result shows improperness of the objective. An inter-vehicle control amount is corrected based on the obtained relative acceleration. The distance between the preceding vehicle and the controlled vehicle is controlled based on the corrected inter-vehicle control amount.

Apparatus and method for controlling a distance between traveling vehicles and actuating a warning device and a recording medium for storing related program

An informing apparatus is designed for use with a cruise control system having at least one of a function of inter-vehicle control for enabling a present vehicle to follow a preceding vehicle and a function of constant-speed travel control for enabling the present vehicle to travel at a constant speed. In the informing apparatus, a determination is made as to whether or not a main switch is in its ON position. The main switch is designed for setting a state in which the cruise control system can start to operate. A determination is made as to whether or not a set switch is in its OFF position. The set switch is designed for commanding execution of cruise control. A speed of the present vehicle and a setting lower limit vehicle speed are indicated on a contradistinction basis when it is determined that the main switch is in its ON position while the set switch is in its OFF position. The setting lower limit vehicle speed denotes a lower limit of a vehicle speed range in which the cruise control is enabled.
