Problems solved by technology

Therefore, there is a problem that when the vehicle is transported for a long time for export / import, or when it is not driven for a long time, the vehicle cannot be started at the delivery site or construction site, and the battery needs to be recharged
[0009] However, it can be expected that considerable labor and expense will be required to remove the cable directly or indirectly from the battery end

Abstract

The invention relates to a safety device of an industrial vehicle and a safety function control method, which are used for controlling while stopping and starting industrial vehicles to ensure that a safety function is executed only in a specified period of time. In the invention, a timer is driven under the condition that a starting key is closed, and a servo power supply used for executing the safety function is cut off after reference time so as to stop executing the safety function. The invention can reduce a current value of dark current generated by continuing to executing the safety function when the vehicle starting is stopped so as to prolong the discharge time of batteries.

Description

technical field [0001] The present invention relates to a safety device and a safety function control method for an industrial vehicle, and more particularly to an industrial vehicle for reducing electric leakage generated when a vehicle start key is turned OFF in an industrial vehicle to which a safety system (OSS: Operator Safety System) is applied A safety device and a safety function control method. Background technique [0002] Most of the industrial vehicles currently in use are equipped with safety systems. The so-called safety system is related to the safety of the driver, and is a system that notifies the driver of a safety warning through a message or a warning sound when there is an abnormal behavior in the vehicle operation. [0003] This type of safety system grasps whether the vehicle is running or not, whether the operating device is operating or not, and the parking state when the driver leaves the driver's cab and is not in a normal vehicle operating enviro...
