ABSTRACT:
A sensor failure and erroneous signal detection system for use in automobiles equipped with cruise control. This system prevents cruise control from operating if certain predetermined conditions occur. Further, the system will determine if the cruise control signal has been erroneously generated and set up an error "flag". A failure is determined in the cruise control system if either one of the following conditions is present when a cruise control signal is generated: (1) the vehicle is traveling below a predetermined speed; (2) the brake switch is on; (2) the shift range is in "N", "R" or "P"; or (4) either (1), (2) or (3) continues for a predetermined period of time. Upon occurrence of (1), (2), (3), or (4), an error has been detected and the automatic transmission is instructed to return to normal operation.
