Abstract
Abstract In apparatus and method for cruise control for an automotive vehicle, a controller is provided for running a self-diagnosis upon a receipt of the power supply via the first switch, for determining whether the apparatus operates normally or abnormally as a result of the run of the self-diagnosis, and for starting an acceptance of an input of the signal from the second switch when determining that the apparatus operates normally as the result of the self-diagnosis, and for issuing a warning signal when determining that the apparatus operates abnormally when the input of the signal from the second switch occurs at a time of the start of the acceptance of the input of the signal from the second switch and the input of the signal from the second switch occurs after a predetermined time has passed from the time when the acceptance of the input of the signal from the second switch occurs.

Independent Claim
186 words
An apparatus for an automotive vehicle, comprising: a first switch, responsive to a turn on thereof, for supplying a power supply to the apparatus; a second switch, responsive to a turn on thereof, for outputting a signal to start a cruise control of the apparatus; and a controller for running a self-diagnosis upon a receipt of the power supply via the first switch, for determining whether the apparatus operates normally or abnormally as a result of the run of the self-diagnosis, and for starting an acceptance of an input of the signal from the second switch when determining that the apparatus operates normally as the result of the self-diagnosis, and for issuing a warning signal when determining that the apparatus operates abnormally when the input of the signal from the second switch occurs at a time of the start of the acceptance of the input of the signal from the second switch and the input of the signal from the second switch occurs after a predetermined time has passed from the time when the acceptance of the input of the signal from the second switch occurs.
Claim 3
Dependent Claim
84 words
An apparatus for an automotive vehicle as claimed in claim 1, wherein the controller determines that the apparatus operates normally when the input of the signal from the second switch occurs at the time when the acceptance of the input of the signal from the second switch occurs and when no input of the signal from the second switch occurs after the predetermined time has passed from the time at which the acceptance of the input of the signal from the second switch occurs.
Claim 4
Dependent Claim
95 words
An apparatus for an automotive vehicle as claimed in claim 2, wherein the controller starts the cruise control upon the receipt of the signal from the second switch when at the time of the start of the acceptance of the input of the signal from the second switch, the input of the signal from the second switch occurs and when no input of the signal from the second switch occurs after the predetermined time has passed from the time of the start of the acceptance of the input of the signal from the second switch.
Claim 5
Dependent Claim
44 words
An apparatus for an automotive vehicle as claimed in claim 2, which further comprises a lamp connected to the controller which is turned on when the input of the signal from the second switch occurs after the controller determines that the apparatus operates normally.
Claim 6
Dependent Claim
27 words
An apparatus for an automotive vehicle as claimed in claim 1, wherein the lamp is repeatedly turned on and off when the controller issues the warning signal.
Claim 7
Dependent Claim
39 words
An apparatus for an automotive vehicle as claimed in claim 1, wherein the first switch and second switch are disposed at adjacent positions so as to enable a simultaneous turn on of the both the first and second switches.
Claim 8
Dependent Claim
70 words
An apparatus for an automotive vehicle as claimed in claim 1, which further comprises a vehicle speed sensor for detecting a vehicle speed of the vehicle and wherein the vehicle speed detected by the vehicle speed sensor when the controller determines that the apparatus operates normally and the input of the signal from the second switch occurs is a target vehicle speed at which the vehicle speed is maintained constantly.
Claim 9
Dependent Claim
37 words
An apparatus for an automotive vehicle as claimed in claim 1, wherein the first switch is a main switch of a toggle switch type connected between an ignition power supply for a vehicular engine and the controller.
Claim 10
Independent Claim
198 words
An apparatus for an automotive vehicle, comprising: first switching means, responsive to a turn on thereof, for supplying a power supply to the apparatus; second switch means, responsive to a turn on thereof, for outputting a signal to start a cruise control of the apparatus; third means for running a self-diagnosis upon a receipt of the power supply via the first switch means; fourth means for determining whether the apparatus operates normally or abnormally as a result of the run of the self-diagnosis; fifth means for starting an acceptance of an input of the signal from the second switch means when determining that the apparatus operates normally as the result of the self-diagnosis; sixth means for issuing a warning signal when the fourth means determines that the apparatus operates abnormally when the input of the signal from the second switch means occurs at a time of the start of the acceptance of the input of the signal from the second switch means and the input of the signal from the second switch means occurs after a predetermined time has passed from the time when the acceptance of the input of the signal from the second switch means occurs.
