BACKGROUND OF THE INVENTION
[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] Working vehicles, such as tractors, are generally prime movers to which various implements are attached to carry out different applications in a field, haulage, construction equipment and various other requirements. Power requirements vary for different applications and input conditions including soil, gradient, size and engagement depth of implement etc. While working vehicles, such as tractor, is engaged in an application, demand for power required at wheels or power take off (PTO) Shaft keeps changing dynamically. The peak load requirements sometimes spike to typical values of 10-30% of rated capacity, and in such conditions even an engine back up torque is not capable of meeting this additional power requirements.
[0004] Intermittent peak torque spikes are overcome either by manoeuvring speed reductions or increasing throttle position or combination of both. In certain conditions, an engine may get stalled resulting in damage to the tractor in extreme cases. These actions lead to either loss in productivity or fuel efficiency or both.
[0005] This requirement of increased power at current level leads to design and development of tractors with higher capacity engine to meet the extra power requirement and forces operators to opt for a tractor with higher rated power than normally required for majority of the operations in most of the conditions.
[0006] To overcome this problem, a solution is being offered where the operator is able to draw additional power, as and when required intermittently, with an existing engine and without compromising on fuel efficiency and productivity.

In an exemplary embodiment, the set of sensors 138 can be selected from the group including but not limited to speed sensor, torque sensor, velocity sensor and crankshaft sensor. In a preferred embodiment, set of sensors 138 can include speed sensor, torque sensor and the likes.

Each processing unit 140 can include, or be communicatively coupled to, memory having computer executable storage instructions.

[0070] In an embodiment, the processing unit 140 can extract one or more parameter values from the sensed one or more parameter values associated with the speed and the torque of the engine 112. The one or more parameter values can pertain to rotating force of the engine 112, revolution per minute (RPM) of the engine 112, load of the engine 112, and the likes.

The one or more threshold parameter values can be selected from the group including rotating force of the engine 112, revolution per minute (RPM) of the engine 112, load of the engine 112, and the likes. In an exemplary embodiment, the one or more threshold parameter values can include a speed of the crankshaft of the engine 112.

For example, in an auxiliary energy system, we can set threshold speed of the engine to 1600 RPM, the processing unit 140 at every speed can do comparison of real time speed of the engine 112 with the set threshold speed of the engine 112. When required speed can be attained in the engine 112, the speed sensor 138 can transmit signal to the processing unit 140 (real time speed of the engine 112 can be less to predefined threshold speed), the processing unit 140 can send signal to the governor unit 118 to supply corresponding auxiliary electric energy from the Battery 130 to the motor 116.
[0073] In an exemplary embodiment, the torque sensor 138 can be coupled with the processing unit 140 to monitor real-time torque of the engine 112 based on signal received and compare the real-time torque with predefined threshold torque. If on comparison, monitored torque can be more or equal to the predefined threshold torque, signal can be sent to the processing unit 140 for enabling the governor unit 118 to supply corresponding electric energy from the battery 130 to the motor 116. For example, in an auxiliary energy system 100, we set torque of the engine to 200 NM, the processing unit 140 at every torque can do comparison of real-time torque of the engine 112 and predefined threshold torque of the engine 112. When required torque can be attained in the engine 112, the torque sensor 138 can give signal to the processing unit 140 (in this case, real-time torque of the engine 112 can be less than predefined torque), the processing unit 140 can send signal to the governor unit 118 to supply corresponding auxiliary electric energy to the motor 116.
[0074] In an embodiment, the controller 120 can be configured with the governor unit 118, such that corresponding actuation of the controller 120 can enable the governor unit 118 to supply corresponding electrical energy from the battery 130 to the motor 116, and the motor 116 can provide corresponding auxiliary energy to the engine 112.

In another embodiment, the first relay 126 can be configured with the cut off actuator 128 and the governor unit 118.

[0081] In an embodiment, the system 100 can include an external charger 134, which can be removably coupled with the Battery 130. The external charger 134 can recharge the battery with an external electrical means. In an exemplary embodiment, the external charger 134 can be selected from group comprising external charger, internal charger, and the likes. In an exemplary embodiment, a provision can be made on the battery 130 to connect with an external charger 134 with adapter to connect with external AC power supply. As and when required, the battery 130 can have provision to connect to external 230V AC charging point via the external charger. In another exemplary embodiment, an arrangement can charge the battery 130 when the working vehicle is not in running condition.
[0082] In an embodiment, recharging of the battery 130 can be done via an internal regeneration charging and the external charger 134. The internal regeneration charging can include various pre-conditions for the auxiliary energy system 100 to get activated such as the engine 112 in on position and be in running mode, the operator switch 202 (as shown in FIG. 2) can be in on position, the selector switch 136 can be either in manual mode or auto mode, and the controller 120 can be in minimum (or zero) position. On fulfilling the preconditions, the governor unit 118 can be enabled to receive the electrical energy from the motor 116. The governor unit 118 can convert the electrical energy to suit charging the level required to recharge the battery 130. An electrical energy path for charging activity can be from the motor 116 to the governor Unit 118, the first relay 126, then to the cut-off actuator 128, and then to the battery 130. Thus, as long as above pre-conditions are valid and the working vehicle engine is running and the battery 130 is not fully charged, the governor unit 118 can enable recharging of the battery 130.
[0083] In an exemplary embodiment, the selector switch 136 can be electrically connected to the processing unit 140. The torque sensor 138 and s peed sensor 138 can be electrically connected to the processing unit 140. Further, the processing unit 140 can be electrically connected to the governor unit 118 to transmit an automatic throttle reference signal from the processing unit 140 to the governor unit 118. Also, the governor unit 118 can transmit readiness status signal to the processing unit 140. Before the start of operations needing usage of the auxiliary energy system 100, the working vehicle operator first selects appropriate mode on the selector switch 136, which has three positions off, manual mode, and an automatic mode. When the operator selects the manual mode on the selector switch 136, the auxiliary energy system 100 requires an input from the processing unit 140 to confirm the engine on-off status, which can be fed to the processing unit 140 by the torque sensor 138 and speed sensor 138. Once circuit is complete, the selector mode 136 can transfer the signals to the activation relay 124. Selection of the automatic mode by the operator, the selector switch 136 can require an input from the processing unit 140 to confirm the engine on-off status, which can be fed to the processing unit 140 by the torque sensor 138 and the speed sensor 138. Once circuit is completed, the selector switch 136 can transfer signal to the activation relay 124, which in turn triggers signals to the indicator 122 and also to the activation relay 124. The first relay 126 can transmit a voltage from the battery 130 to the governor unit 118 via the cut-off actuator 128. The cut-off actuator 128 can always be in an on position for the auxiliary energy system 100 to function. In case of emergency situations, the cut-off actuator 128 can be switched off to isolate the auxiliary energy system 100. Thus, the cut-off actuator 128 can act as a safety feature. Also, when the operator select an auto mode position on the selector switch 136, the governor unit 118 receives an electrical signal from the processing unit 140. The processing unit 140 to send and receive electrical signals to and from the governor unit 118. A two-way communication can ensure readiness of the governor unit 118 to receive an automatic throttle reference signal from the processing unit 140. A power can be made available to the governor unit 118 and can be ready to supply require electrical energy to the motor 116. In an automatic mode, the processing unit 140 can perform dual function such as the processing unit 140 signals the engine 112 on-off status to the selector switch 136, and the processing unit 140 can generate the automatic throttle reference signal and transmits the same to the governor unit 118.
[0084] In an exemplary embodiment, the processing unit 140 can continuously monitor an instantaneous speed and the torque developed by the engine 112 from the torque sensor 138 and the speed sensor 138. Both the engine speed and the engine torque values can be in continuous comparison with an in-built database of the engine 112, which can be already fed to the processing unit 140. A deviation in base values, and an actual instantaneous value triggers the automatic throttle reference signal, which can be transmitted to the governor unit 118. Based on proportional input of the automatic throttle reference signal from the processing unit 140, the governor unit 118 can supply required electrical energy to the motor 116. The motor 116, in turn, drives the engine 112 by transmitting power to the crankshaft of an engine 112 via the flexible coupling 114, while the engine 112 be in running condition. A supply of the electric energy or the auxiliary energy system 100 can be activated during the auto mode to supply intermittent additional power to the engine 112 as and when required.
[0085] FIG. 2 illustrates a schematic diagram of the proposed auxiliary energy system 100 for working vehicle in manual mode, in accordance with embodiments of the present disclosure.
[0086] In an exemplary embodiment, the working vehicle operator can anticipate requirement of intermittent additional power, the operator can switch on the operator switch 202. The operator switch 202 can require an input from the engine ON-OFF sensor 204. Once a circuitry is completed successfully, the operator switch 202 can transfer the signal to the activation relay 124. The activation relay 124 can trigger signals to the indicator 122 and also to the first relay 126. The first relay 126 can transmit voltage from the battery 130 to the governor unit 118 via the cut-off actuator 128. The cut-off actuator 128 can always be in an on position for the auxiliary energy system 100 to function. In case of emergency situations, the cut-off actuator 128 can be switched off to isolate the auxiliary energy system 100. Thus, the cut-off actuator 128 can act as a safety feature. Once the above actions are completed, the electric energy can be made available to the governor unit 118. However, level of power required can be unknown to the governor unit 118. This can be accomplished by actuation of the controller 120. While performing working vehicle operations, when the need for additional power can be sensed, the operator in manual mode can actuates the controller 120 from its original minimum position or zero position. The controller 120 can be in the form of a joystick, a knob, a lever or any similar part, which can deliver same function and can be conveniently positioned on the working vehicle within ergonomic reach and efforts of the operator. The actuation of the controller 120 can send signal to the governor unit 118 in proportion to level of actuation from minimum position (or zero position) to a maximum position (or end position). Based on a proportional inputs signal from the controller 120, the governor unit 118 can supply required electrical energy to the motor 116. The motor 116, in turn, drives the engine 112 by transmitting power to the crank shaft of engine 112 end via the flexible coupling 114 while the engine 112 can be in running condition. This additional power, transmitted to the engine 112 by the motor 116, acts as supply of auxiliary energy. Once requirement of the auxiliary energy is fulfilled, the operator shifts the controller 120 back to its minimum position (or zero position).
[0087] In an embodiment, the auxiliary energy system 100 can include an engine ON-OFF sensor 204, which can be operatively coupled with the processing unit to detect ON and OFF condition of the engine 112, and generate an alert signal based on detected condition. In an exemplary embodiment, the engine ON-OFF sensor 204 can include but not limited to engine ON-OFF sensor, proximity sensor, and the like.

[0089] In an embodiment, in part A 302 of the auxiliary energy system 100, a power can be generated in the engine 112, and can be transmitted through the clutch 110 to the gear box 108 to the differential 106 to a rear axle which can drive the wheels. The power can also be drawn through the gear box 108 to power take-off (PTO) shaft 102, which can be situated at a rear end, and which in turn can be used in various applications. Further, the power can be drawn from the engine 112 by a hydraulic system used for lifting, holding, and lowering of the implements. Apart from this the power from the engine 112 can also be drawn for running other utilities such as power steering, alternator etc.
[0090] In an embodiment, in part B 304 of the auxiliary energy system 100, the motor 116 can be coupled with the engine 112 via the flexible coupling 114 in such a configuration that the crank shaft of engine 112 and the drive shaft of the motor 116 can be permanently engaged with each other. Thus, while one end of the engine 112 can be connected to the clutch 110, the other end (through the engine crank shaft) can be in direct and permanent connection with the motor 116 via the flexible coupling 114. The flexible coupling 114 can be selected from the group including rigid, flexible, universal joints, sleeve with splines, sleeve with key, any other types of rigid or the flexible couplings, and the likes. The flexible coupling 114 can be customized to reduce vibrations, mechanical losses and absorb shock loads. The motor 116 can be electrically coupled with the governor unit 118, which in turn can be electrically coupled with the battery 130. The governor unit 118 can be electrically coupled with the controller 120. The battery 130 can supply electrical power to the governor unit 118, which in turn transfers the electrical energy to the motor 116 can be in controllable form which can be regulated by an input given to the governor unit 118 by the controller 120. The motor 116 can convert the electrical energy into mechanical energy in a rotary motion, and the same can be transferred to the engine 112 via the flexible coupling 114.
