Abstract

The object of the present invention is to provide a multifunctional detector wherein two sensors, for detecting the rotational speed of the transmission gear and for detecting the temperature of the transmission oil are disposed in proximity in a single unit so that they can be connected easily to a control ECU through a single connector. The multifunctional detector for an engine according to the present invention is configured such that a sensor for detecting the rotational speed of the gear within a transmission for a vehicle and a sensor for detecting the temperature of the surrounding transmission oil are mounted on the same circuit board and provided in a single case, and such that a housing chamber therefor is filled with a resin having high thermal conductivity, and the outputs of both sensors are performed from a single connector.

Description

technical field [0001] The present invention relates to a multifunctional detection device for an engine, in particular to a composite device of a sensor for detecting the spindle speed of a transmission of an engine such as an automobile and a sensor for detecting the temperature of transmission oil of a control gear of the transmission. Background technique [0002] Conventionally, a sensor for detecting the spindle speed of a transmission of an engine of an automobile or the like and a sensor for detecting a transmission oil temperature of the transmission gear are attached to the transmission device as separate devices. Although the above-mentioned sensors are located adjacent to each other, they are installed as independent devices, and the output lines are also wired from the connectors to the control ECU. In addition, in addition to this, the transmission device is also equipped with many types of sensors, and the surrounding wiring is relatively complicated. [0003...
