ENGINE CONTROL DEVICE FOR A WORK VEHICLE

摘要

An engine control device for a vehicle, comprising: a control unit (2) configured to be connected to the engine of a vehicle and to control the switching of the engine from a first idle rotation speed to a second idle rotation speed in which the number of engine revolutions is lower compared to the number of revolutions of the first idle speed; a first sensor (3), configured to be connected to the engine and to instantaneously sense and transmit to said control unit (2) the number of revolutions completed by the engine in the unit of time; a second sensor (4) for detecting the presence of an operator at the vehicle controls, which second sensor (4) is configured to transmit to the control unit a signal indicating the presence of an operator at the vehicle controls. The control unit (2) is configured to actuate a decrease in the engine rotation speed from the first idle speed toward the second idle speed if the signal transmitted by the second sensor (4) indicates the operator's absence and the signal transmitted by the first sensor (3) indicates that the engine is running at the first idle speed.
