Multifunction electronic meter for vehicle
First Claim
1. A multifunction electronic meter for a vehicle comprising:
- an electronic indicator on a display section of which a plurality of informations derived respectively at least from a fuel amount sensor, a water temperature sensor, an oil pressure sensor and a battery are selectively displayed together with a plurality of symbolmarks provided respectively for identifying and warning said plurality of informations displayed selectively on said display section,a display control circuit for controlling said display section such as a principal information consisting of an amount of fuel among said plurality of informations is ordinarily displayed and, when either one of said plurality of informations other than said principal information is selected, said one information is displayed, together with a respective one of said plurality of symbolmarks,a plurality of emergency discriminators for discriminating respectively a plurality of emergencies relating respectively at least to the poor fuel amount, the too high water temperature, the too low oil pressure, and the too low battery voltage,a switching circuit arranged so that, when either one of said plurality of emergency discriminators discriminates one of said plurality of emergencies, the information relating the discriminated emergency is displayed regardless of the contents of the display on said display section of said electronic indicator,a self-reversion circuit arranged so that said principal information is displayed automatically reversionally when a predetermined time duration is expired after one of said plurality of informations other than said principal information is selectively displayed,a hold switch for holding either one of said plurality of informations other than said principal information as it is displayed selectively by annulling the operation of said self-reversion circuit, andan initially setting circuit arranged so that the information which is held by the operation of said hold switch as it is displayed selectively is switched over reversionally to said principal information when an ignition switch is closed.

Abstract
A multifunction electronic meter for a vehicle can display selectively plural measured informations of fuel amount, cooling water temperature, oil pressure, battery voltage and the like of a vehicle on a single display section, the displayed informations being accompanied respectively with combinations of symbolmarks and surrounding frames thereof for identifying and warning those informations.
The principal information of, for instance, fuel amount is ordinarily displayed, while the remaining informations are displayed selectively as occasion demands, for instance, in response to the occurrence of an emergency. When plural emergencies are simultaneously caused, the information corresponding to the lastly caused emergency is displayed intermittently together with the symbolmark, while only the symbolmarks and the frames of the informations corresponding to the previously caused emergencies are displayed continuously. Consequently, the most requisite measured information can be ordinarily noticed by a driver, as well as the remaining informations which are noticeable as occasion demands, regardless of the desired simplicity of configuration of an instrument panel of the vehicle.
