Embodiment Construction

[0038] figure 1 is a view showing a state where a vehicle to be towed is connected to an eco-friendly vehicle according to an embodiment of the present disclosure.

[0039] refer to figure 1 , the eco-friendly vehicle 100 according to an embodiment of the present disclosure is a main body towing the vehicle 150 to be towed, and the vehicle 150 to be towed is a towing object towed by the eco-friendly vehicle 100 . For example, the vehicle to be towed 150 may include a camper trailer or a cargo transport trailer or a jet ski transport loader.

[0040] Eco-friendly vehicle 100 is a vehicle that uses electric power of a battery as energy, and may be an electric vehicle or a hybrid vehicle.

[0041] The eco-friendly vehicle 100 is communicably connected to the vehicle 150 to be towed. The eco-friendly vehicle 100 and the vehicle to be towed 150 exchange driving information, vehicle status information and towing status information through mutual communication.

Abstract

The present disclosure relates to an eco-friendly vehicle and a control method of the eco-friendly vehicle that optimizes a temperature of a battery of the eco-friendly vehicle that draws a vehicle to be dragged. A control method of an eco-friendly vehicle includes: measuring, by a controller, a battery temperature during traction travel in a state in which a vehicle to be towed is connected; applying, by the controller, the measured battery temperature to a predetermined function to obtain a trend of battery temperature change; predicting, by the controller, a point in time at which the temperature of the battery exceeds a predetermined reference temperature based on a trend in which the temperature of the battery changes; and starting, by the controller, cooling the battery before reaching the predicted point in time exceeding the predetermined reference temperature.

Description

technical field [0001] The present disclosure relates to a vehicle, and more particularly, to an eco-friendly vehicle having a towing device capable of towing a vehicle to be towed and using electric power of a battery as energy. Background technique [0002] As the population enjoying leisure activities such as camping and traveling increases, the demand for trailers that are separately attached to vehicles for storing various items or for mobile accommodation is also increasing. [0003] Generally, a trailer is coupled to a vehicle using a hitch provided at the rear of the vehicle, and moved by traction of the vehicle. That is, a typical trailer has only wheels and a rotating shaft, and does not itself generate separate power to drive the wheels. [0004] As noted above, since a typical trailer does not itself have a separate power source for driving the wheels, overloading of the powertrain of the towing vehicle caused by the weight of the trailer can become a problem wh...
