Headway control system
First Claim
1. A vehicle headway control system, comprising:
- a following control unit that performs a following control which causes a host vehicle to follow a preceding vehicle in congested traffic;
wherein, after the host vehicle has come to a standstill, the following control unit autonomously starts following control of the host vehicle upon detecting that a characteristic value generated in the host vehicle indicates that the host vehicle has started moving in response to a demand for a resumption of movement input by a driver.

Abstract
To provide a headway control system, in which a congestion following processing can be started by the same operation as in ordinary driving. An arrangement is provided that lets a following control unit 10 to start a control to follow a preceding vehicle on condition that a characteristic value, which is produced in a host vehicle when a driver starts moving the host vehicle, is detected in congested traffic. Acceleration or a vehicle speed may be used as the characteristic value. Another possible arrangement is to start the following control on condition that a variation in an engine of the host vehicle, which is generated in the host vehicle when the driver operates to start moving the host vehicle, is detected in congested traffic. For example, the following control may be started under condition that at least either one of the following is detected: an increase in an engine speed, an increase in an intake pressure, an increase in an injection pulse width, an increase in an engine oil pressure, and an increase in the number of ignition pulses.

10. A vehicle headway control system, comprising:
a following control unit that performs a following control which causes a host vehicle to follow a preceding vehicle in congested traffic, wherein the following control unit autonomously starts the following control on condition that it detects that the host vehicle remains stationary, the preceding vehicle has started moving, and a shift lever of a transmission is in a drive range. - View Dependent Claims (11, 12)

13. A vehicle headway control system, comprising:
-
a following control unit that performs following control of a host vehicle, causing it to follow a preceding vehicle in congested traffic;
means for measuring a characteristic value that is indicative of a degree of movement of said vehicle in response to an input demand from an operator of said host vehicle;
means for generating a triggering signal indicative of a start of movement of said host vehicle when said characteristic value exceeds a preset value;
means for autonomously initiating following control of said host vehicle by said following control unit in response to receipt of said triggering signal. - View Dependent Claims (14, 15, 16, 17)

18. A vehicle headway control system, comprising:
-
a following control unit that performs a following control which causes a host vehicle to follow a preceding vehicle in congested traffic; and
means, operative after the host vehicle has come to a standstill, for generating a vehicle following control starting signal when a characteristic value generated in the host vehicle reaches a magnitude indicative that the host vehicle has started moving in response to an input demand for a resumption of movement from a driver;
wherein said following control unit autonomously commences following control operation upon receipt of said vehicle starting signal. - View Dependent Claims (19)
