Abstract

An industrial vehicle which is equipped with an engine and having an Eco-mode in which torque of the engine is restricted includes an accelerator, an accelerator opening detector that detects an opening of the accelerator, a vehicle speed detector that detects a speed of the vehicle, an engine speed detector that detects a speed of the engine, and a torque restriction releasing unit which, when the torque of the engine is restricted, if conditions that the opening of the accelerator detected by the accelerator opening detector is a first predetermined value or greater, that the vehicle speed detected by the vehicle speed detector is a second predetermined value or smaller and that the engine speed detected by the engine speed detector is a third predetermined value or smaller are satisfied, releases the torque restriction.

Claims5

Dependent claims

An industrial vehicle which is equipped with an engine and has an Eco-mode in which torque of the engine is restricted, comprising:

an accelerator;
an accelerator opening detector that detects an opening of the accelerator;
a vehicle speed detector that detects a speed of the vehicle;
an engine speed detector that detects a speed of the engine;
and
a torque restriction releasing unit which, when the Eco-mode is ON, turns OFF the Eco-mode to release the restriction of the torque of the engine temporarily, based upon all of the following conditions being satisfied;
(i) the opening of the accelerator detected by the accelerator opening detector is a first predetermined value or greater;
(ii) the vehicle speed detected by the vehicle speed detector is a second predetermined value or smaller;
and (iii) the engine speed detected by the engine speed detector is a third predetermined value or smaller.
