Electronically Controlled Throttle Control Device
16 Sep 20
In an electronically controlled throttle control device in which a throttle control output command calculated by an electronic control unit (ECU) is calculated based on a throttle main control command, calculated from a throttle opening deviation which is a difference between a throttle opening command and a throttle opening detection signal, and a throttle correction control command which is a value obtained by integrating a product of the throttle opening deviation and a coefficient, the coefficient for calculation of the throttle correction control command is changed depending on a driving state based on an acceleration state and a deceleration state of a throttle and a small throttle deviation state.

Fuel pressure monitoring system of vaporizer
25 May 20
Provided is a fuel pressure monitoring system of a vaporizer using a safety module which issues a fault signal by detecting a pressure using a fuel pressure sensor disposed in a pressure regulating chamber of the vaporizer within a predetermined time after an engine is stopped and determining that the pressure regulating mechanism fails when the detected pressure exceeds a threshold stored in a storage device to be increased to a predetermined pressure or higher, and the pressure regulating mechanism is determined to fail only when a water temperature of cooling water in the engine of the vaporizer reaches a predetermined temperature at which warming up of the engine can be determined to be completed.
