BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for a hybrid tractor, and more particularly to a display device for a hybrid tractor including a booster gauge display part, a battery gauge display part, and a motor gauge display part. .

Generally, a hybrid vehicle refers to a vehicle driven by two power sources, and uses a battery as an energy storage device of a hybrid vehicle. In order to achieve a high fuel economy, the hybrid vehicle as described above includes a generator, a rechargeable battery, a motor, and the like in addition to the structure of an existing internal combustion engine. The mechanical energy for driving the vehicle, And is used as a generator input. The mechanical energy of the engine delivered to the generator is output as electrical energy by rotating the rotor of the generator. The electrical energy output from the generator is stored in the battery, and is stored in the engine together with the mechanical energy, And acts as a driving force for driving the vehicle.

Hybrid cars and hybrid tractors have big differences in driving methods. The main operation region of the hybrid vehicle is shifted from the idle state to the maximum torque point and a shift occurs near or below the maximum torque point. The vehicle starts from the idling state and determines the torque amount of the engine in accordance with the driver's manipulated amount of the accelerator (acceleration will). The vehicle is accelerated or decelerated by the difference between the running load (air resistance, road surface, inclination) do. In other words, the driver's intention is to change the speed of the vehicle. On the other hand, in the hybrid tractor, the main operation range is from the high idle state to the maximum torque point, and in order to work at a constant speed, a high idle or constant engine revolutions .

During operation, the engine torque is generated by the work load (resistance), and when the load is greater than the maximum torque that can be generated in the set speed lever state, the engine speed decreases. In other words, the factor that changes the speed of the vehicle is that the speed of the tractor is determined by the workload in contrast to the driver's will.

In a typical vehicle there are different information and communication areas to which the indicator is assigned. The indicating instruments provide information to the driver and the passenger. The indicating instruments also assist the operator in navigating or communicating with the outside world. The display particularly visually displays traffic or driving-related data of the vehicle. Near the primary sight of the driver, a so-called combinational instrument is placed. Generally, the combination gauge is located in the cockpit of the handle back and is visible by opening the handle. The combination gauge in particular displays vehicle speed, tank level, air-conditioner temperature and other driving-related information. Radio and audio functions can also be displayed. Menus for telephones, navigation, computer communication services and multimedia applications can also be displayed.
