Automatic cruising control apparatus

An automatic cruising control apparatus for a vehicle including acceleration and deceleration means comprising:

• detecting means for detecting a value corresponding to an actual distance between said vehicle and a preceding vehicle;
• acceleration and deceleration detecting means for detecting actual acceleration and deceleration of said vehicle;
• acceleration and deceleration control means for controlling acceleration and deceleration of said vehicle in accordance with a target control value;
• determining means for determining said target control value so as to equalize said value to a target value corresponding to a target distance between said vehicle and said preceding vehicle;
• and
• informing means for informing a driver of said vehicle how closely at least one of said target control value and said actual acceleration approaches to an operation limit value of said acceleration and deceleration means.

An automatic cruising control apparatus for a vehicle comprising:

• detecting means for detecting a value corresponding to an actual distance between said vehicle and a preceding vehicle;
• acceleration and deceleration control means for controlling acceleration and deceleration of said vehicle so as to equalize said value to a target value corresponding to a target distance between said vehicle and said preceding vehicle, wherein said acceleration and deceleration control means includes a plurality of deceleration means having different deceleration abilities to said vehicle, a part of a plurality of said deceleration means being selectively operated;
• and
• informing means for informing a driver of said vehicle that a total of deceleration derived by said part of a plurality of said deceleration means agrees with a maximum deceleration force of a plurality of said deceleration means, when said total of deceleration derived by said part of a plurality of said deceleration means agrees with said maximum deceleration force of a plurality of said deceleration means.
