TECHNICAL FIELD
[0001] The present disclosure, in general, relates to vehicles. The present disclosure, particularly, relates to a system and method to wirelessly control the power take-off system of a vehicle.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Traditionally, vehicles such as tractor can be used for various tasks on the farm, including threshing, water transport, power generation, drilling, bore well digging, and shredding. Tractors are used in roller testing to evaluate the performance and durability of heavy-duty vehicles. By pulling a loaded trailer over a series of rollers that simulate different road conditions, the tractor can measure the vehicle's power and performance under different weights and speeds. This allows manufacturers to identify potential issues with their vehicles and make necessary improvements before releasing them into the market. Tractors are also used in torture track and water wading testing to evaluate their off-road capabilities. These types of tests are essential for ensuring that tractors can perform in various terrains and weather conditions, maximizing their efficiency and productivity on the farm.
[0004] Often times the operator has to locate the tractor in the field in dark. Operating the headlight and parking light of the tractor wirelessly may help in locating the tractor in the dark.
[0005] Power Take-Off (PTO) is a mechanism commonly found in tractors and other agricultural or industrial machinery. It allows the transfer of mechanical power from the engine of the tractor to various attachments or implements. Power take off offer versatility, efficiency, and convenience but require proper understanding, maintenance, and safety precautions for optimal use.
[0007] Traditional tractor operation requires the operator to be seated in the driver's seat, which can be dangerous in certain situations, such as when operating on steep terrain or when using certain implements. In addition, if the driver is not present near the instrument panel of the tractor and an accident occur due to operation of the implement, the driver has to run towards the tractor to access the instrument panel to deactivate the Power take off system. This might aggravate the damage done by the implement.
[0008] Accordingly, there is a need for a method and a system to wirelessly control the power take-off system of a vehicle.

The second relay 301b act as a switch between the battery of the vehicle and the engine 104. When the vehicle controller 102 receives the engine control signal, the vehicle controller 102 determines the ignition condition of the vehicle. The vehicle controller 102 activates the engine when the ignition of the vehicle is activated. In particular, when the vehicle controller 102 receives the engine control signal and the ignition of the vehicle is activated, the second relay 301b activates the engine 104 by closing the circuit between the engine 104 and the battery. Thus, the activation of the engine 104 only occurs when the first relay 301a closes the circuit between the ignition switch 103 and the battery. The engine 104 provides a feedback signal to the vehicle controller 102 when the second relay 301b close the circuit between the battery and the engine 104.
[0012] When the vehicle controller 102 receives the engine deactivation control signal, the vehicle controller 102 deactivates the engine 104.

[0015] FIG. 4 illustrates a flow chart of the method 400 to wirelessly control the power take-off of the vehicle that can be utilized to implement an exemplary embodiment of the present disclosure.
[0016] At block 402, the method 400 comprises transmitting PTO control signals upon user input on key FOB 101. The user presses the PTO control key 202c on the key FOB 101 to activate the PTO system. A PTO control signal is generated by the FOB controller 201. The generated PTO control signal is then transmitted to the vehicle controller 102 by RFID chip 203.
[0017] At block 404, the method 400 comprises receiving a PTO activation signal transmitted by the key FOB 101. The generated PTO control signal in the step 402 is received by the vehicle controller 102. The vehicle controller 102 has a receiver that is configured to receive the PTO control signal.
[0018] At block 406, the method 400 comprises determining the operating condition of the engine 104. Since the PTO system takes power from the engine 104 of the vehicle, it is essential for working of the PTO system 105 that the engine 104 is activated. In case the engine 104 is not in activated state, there is no point in activating the PTO system 105 as there will be no input power. Accordingly, when the vehicle controller 102 receives the PTO activation signal, the vehicle controller 102 determines the operating condition of the engine 104.
[0019] At block 408, the method 400 comprises activating the PTO system 105 when the engine 104 is in ON condition. Only after determining the operating condition of the engine 104 is in ON state, the vehicle controller 102 activates the PTO system 105. The third relay 301c activates the power take-off system 105 by closing the circuit between the power take-off system 105 and the battery when the engine is in ON condition. The activation of power take-off system 105 initiates power transfer from the vehicle engine 104 to the implements connected with the vehicles.
[0020] FIG. 5 illustrates the flow chart followed by the system to wirelessly control the power take-off of the vehicle. The first step (step 502) to activate power take-off system 105 is to start ignition of the vehicle. The user can initiate the ignition by pressing ignition control key 202a on the key FOB 101. The key FOB 101 transmits the ignition activation control signal to the vehicle controller 102. The vehicle controller 102 authenticates the ignition activation control signal and activate the ignition switch 103 to start ignition. If the authentication fails, the ignition switch 103 is not activated. In particular, when the vehicle controller 102 receives the ignition activation control signal, the first relay 301a activates the ignition switch 103 by closing the circuit between the ignition switch 103 and the battery. The activation of ignition switch 103 initiate ignition of the vehicle. The ignition of the vehicle can be deactivated by pressing the ignition control key 202a again while the vehicle is in ignition state. The key FOB 101 transmits the ignition deactivation control signal. When the vehicle controller 102 receives the ignition deactivation control signal, the vehicle controller 102 deactivates the ignition switch 103. In particular, When the vehicle controller 102 receives the ignition deactivation control signal, the first relay 301a deactivates the ignition switch 103 by opening the circuit between the ignition switch 301a and the battery. The ignition switch 103 provides a feedback signal to the vehicle controller 102 when the first relay 301a closes the circuit between the battery and the ignition switch 103.
[0021] After ignition of the vehicle, the user can initiate to start the engine 104, Step 504. The user can start the engine 104 by pressing the engine control key 202b. The key FOB 101 transmits the engine control signal to the vehicle controller 102. The vehicle controller 102 authenticates the engine control signal and check if the ignition switch 103 is activated or not. In case the vehicle controller 102 determines that ignition switch 103 is activated, the vehicle controller 102 starts the engine 104. In case the vehicle controller 102 determines that the ignition switch 103 is not activated, the engine 104 could not be start.
[0022] When the vehicle controller 102 receives the engine control signal, the vehicle controller 102 determines the ignition condition of the vehicle. The vehicle controller 102 activates the engine when the ignition of the vehicle is activated. In particular, when the vehicle controller 102 receives the engine control signal and the ignition of the vehicle is activated, the second relay 301b activates the engine 104 by closing the circuit between the engine 104 and the battery. Thus, the activation of the engine 104 only occurs when the first relay 301a closes the circuit between the ignition switch 103 and the battery. The engine 104 provides a feedback signal to the vehicle controller 102 when the second relay 301b close the circuit between the battery and the engine 104.
[0023] When the vehicle controller 102 receives the engine deactivation control signal, the vehicle controller 102 deactivates the engine 104. In particular, When the vehicle controller 102 receives the engine deactivation control signal, the second relay 301b deactivates the engine 104 by opening the circuit between the engine 104 and the battery.
[0024] After starting of the engine 104, the user can activate the power take-off system (step 506) by pressing the power take-off control key 202c on the key FOB 101. The key FOB 101 transmits the PTO activation signal to the vehicle controller 102. When the vehicle controller 102 receives the power take-off activation signal, the vehicle controller 102 determines the operating condition of the engine 104. The third relay 301c activates the power take-off system 105 by closing the circuit between the power take-off system 105 and the battery when the engine is in ON condition. The activation of power take-off system 105 initiates power transfer from the vehicle engine 104 to the implements connected with the vehicles. The user can deactivate the PTO system 105 when the intended operation is over. The PTO system 105 of the vehicle can be deactivated by pressing the PTO control key 202c again while the PTO system 105 is activated. The key FOB 101 transmits a power take-off deactivation signal When the vehicle controller 102 receives the power take-off deactivation signal, the third relay 301c deactivates the power take-off system 105 by opening the circuit between the power take-off system 105 and the battery.
