International ClassesB60K 028/10B60K 028/00 AbstractA system for monitoring carbon monoxide (CO) levels produced by the operation of a vehicle's engine. The system includes a detector in the vehicle's passenger compartment for detecting the concentration of CO inside the compartment and circuitry for generating a HIGH CO signal when the detected concentration of CO inside the compartment is greater than a predetermined level. The system disables the operation of the engine in response to the HIGH CO signal. The system also senses a status condition of the vehicle and inhibits the disabling of the engine when the status condition is sensed.Field of SearchWITH MEANS FOR PROMOTING SAFETY OF VEHICLE, ITS OCCUPANT OR LOAD, OR AN EXTERNAL OBJECTResponsive to absence or inattention of operator, or negatively reactive to attempt to operate vehicle by person not qualified mentally or physically to do so Having automatic control means REPEATER IN UNSPECIFIED TYPE COMMUNICATIONS LINE OR CHANNEL (E.G., RELAY STATION) Internal alarm or indicator responsive to a condition of the vehicle Gas | |
