The disclosure is described in the following paragraphs with reference to Figures 1 and 2. In the figures, the same element or elements which have same functions are indicated by the same reference signs. It is to be noted that, the vehicle is not illustrated in the figures for the purpose of simplicity. One skilled in the art would appreciate that the system and the method as disclosed in the present disclosure may be used in any vehicle including but not liming to commercial vehicles, passenger vehicles, and the like. The system and the method of the present disclosure may also be

implemented in vehicles having manual transmission or automatic transmission, for suitably maneuvering the vehicle without deviating from the principles of the present disclosure.
Figure 1a is an exemplary embodiment of the present disclosure illustrating a block diagram of a system (100) for regulating torque performance of an internal combustion engine (11) [hereinafter interchangeably referred to as “IC engine” or “engine”] of a vehicle [not shown in figures]. The system (100) comprises one or more sensors (1), a fuel injector (9), an exhaust gas regeneration valve (10) and a control unit (12). In an embodiment, the one or more sensors (1) may be at least an accelerator pedal position sensor (2), a speed sensor (3), a torque sensor (4), a gear position sensor (5), a terrain gradient sensor (6), among other sensors, that may be coupled to the engine
(11) and the system (100) for sensing a plurality of operating parameters corresponding to
performance of at least one of an engine (11) of the vehicle.
The system (100) may be configured to determine the plurality of operating parameters to determine the engine performance of the vehicle. In the illustrative embodiment, the plurality of operating parameters are sensed by the one or more sensors (1) associated with the system (100) and in-turn the engine (11) of the vehicle and transmitted as a plurality of signals. The control unit
(12) may be communicatively coupled to an engine control unit (8) of the vehicle, where the
plurality of signals from the one or more sensors (1) are received by at least one of the control unit
(12) and the engine control unit (8). The one or more sensors (1) are configured to sense different
parameters corresponding to the engine performance (10) and that of the system (100). For
instance, at least one sensor of the one or more sensors (1) may be an accelerator pedal position
sensor (2) configured to sense position of the accelerator pedal to determined torque demand that
is a function of the accelerator pedal position. Further, at least one sensor of the one or more sensors
(1) may be a speed sensor (3), configured to sense speed of at least one of the engine (11) and
wheels of the vehicle. At least one sensor of the one or more sensors (1) may be a fuel sensor (7)
which may be capable of sensing characteristics of fuel such as, volume of fuel being supplied to
the engine (11), volume of fuel available in the vehicle, among others. Such plurality of operating
parameters of the engine (11) and the vehicle that may be sensed by each of the one or more sensors
(1) may be communicatively transmitted to at least one of the engine control unit (8) and the
control unit (12). The control unit (12) may be configured to determine the gradient of the terrain

from at least one of the plurality of operating parameters of the engine (11) corresponding to the engine performance, a gradient sensor and a navigation sensor.
In an embodiment, the one or more sensors (1) may be positioned at predefined locations in the vehicle to selectively sense corresponding operating parameters of the vehicle and transmit the plurality of signals corresponding to the plurality of operating parameters at corresponding location of each of the one or more sensors (1) to the engine control unit (8). For example, an RPM sensor may be positioned proximal to the engine (11) for sensing an engine speed or may be positioned proximal to the wheel for sensing vehicle travel speed. Further, the control unit (12) may receive a plurality of signals corresponding to the plurality of operating parameters, where such signals may be transmitted by the engine control unit (8) based on signals from each of the one or more sensors (1) corresponding to each parameter of the plurality of parameters. Based on such plurality of signals from the engine control unit (8), the control unit (12) may be configured to regulate torque performance of the engine (11).
In the illustrative embodiment, the control unit (12) may be configured to regulate torque performance of the engine (11) on determining torque demand of the engine (11). The torque demand of the engine (11) may arise due to at least one of an uphill gradient along the terrain on which the vehicle needs to travel and load to be carried by the vehicle. With that, the control unit (12) may be configured to determine required torque of the engine (11) based on the plurality of operating parameters of the engine (11). Due to the torque generated by the engine (11) being a function of the plurality of operating parameters, variation in the at least one operating parameter of the plurality of operating parameters may vary the torque generated by the engine (11). In an embodiment, the control unit (12) may be configured to determine the torque demand of the engine
(11) based on at least one of the plurality of operating parameters and a signal from the torque sensor (4) of the one or more sensors (1). The control unit (12) may be configured to compare the determined required torque with the torque generated by the engine (11).The control unit (12) may then determine fuel consumption of the internal combustion engine (11) at the determined required torque and based on the performance of the internal combustion engine (11). Then, the control unit
(12) is configured to regulate the fuel consumption by varying at least one parameter associated with the performance of the internal combustion engine (11) in response to the determined required torque of the internal combustion engine (11). For example, the required torque determined by the

control unit (12) may be greater than the torque generated by the engine (11), where the control unit (12) increases the fuel consumption of the engine (11) to generate the required torque. The control unit (12) may be communicatively coupled to a fuel injector (9) and an exhaust gas regeneration valve (10) of the engine (11) wherein when the torque generated is less than the required torque, the control unit (12) may increase the fuel consumption of the engine (11) by controlling at least one of the fuel injector (9) and the exhaust gas regeneration valve (10).
In an embodiment, the control unit (12) may regulate the fuel consumption of the engine (11) when each of the at least one plurality of operating parameters of the engine (11) are in a predetermined range. For example, the control unit (12) may increase the fuel consumption of the engine (11) when at least two of the conditions such as the accelerator pedal position is 100%, the speed of the vehicle is decreasing, the speed of the vehicle is in a predetermined range [may be at least one speed range indicating fuel economy of the vehicle], engaged gear is above a predetermined threshold. Similarly, the control unit (12) may reduce the fuel consumption of the vehicle when the torque generated is less than the required torque. In such scenarios, the control unit (12) may be configured to decrease the fuel consumption of the engine (11) to decrease the torque generated by varying at least one of the plurality of operating parameters of the engine (11). For example, the control unit (12) may reduce the fuel consumption of the engine (11) when at least two of vehicle conditions are sensed by the one or more sensors (1) such as the accelerator pedal position is below a threshold (i.e., in the range of 50% to 70%), gradient of the terrain is substantially horizontal [i.e., in the range of 0˚ to 5˚ from the ground ], engaged gear is being shifted, application of service brakes in the vehicle. The control unit (12) may determine application of service brakes in the vehicle by correlating the vehicle speed and the accelerator pedal position.
In an embodiment, the control unit (12) may reduce the fuel consumption of the engine (11) after a certain period of increasing the fuel consumption, upon comparison of the generated torque with the required torque to maintain fuel efficiency of the engine (11).
In an embodiment, the control unit (12) may be configured to regulate the fuel consumption of the engine (11) between different driving modes of the vehicle corresponding to the fuel efficiency, and the torque generated by the engine (11) in the driving modes preset in the control unit (12) of the vehicle. The system (100) may reduce or eliminate the user intervention in switching between

the driving modes of the vehicle based on fuel consumption at the required torque. For explanation of the invention, the number of driving modes are depicted as two driving modes such as a light mode and a medium mode and the same should not be considered a limitation. For example, when the required torque is greater than the torque generated by the engine (11), the control unit (12) may be configured to switch from the light mode to the medium driving mode to generate the required torque. Further, when the required torque is less than the torque generated by the engine (11), the control unit (12) may be configured to switch from the medium mode to the light mode by reducing the fuel consumption of the engine (11).
In an exemplary embodiment, the control unit (12) may be configured to switch operation of the internal combustion engine (11) between different driving modes of the vehicle. For instance, the different driving modes may include an economy mode, a cruise mode and a performance mode and the like, where the economy mode may indicate that the internal combustion engine (11) does not generate high torque to maintain fuel economy. Similarly, the performance mode may indicate that the engine (11) generates high torque compromising on fuel economy, where the cruise mode may indicate that the engine (11) generates required torque while balancing fuel economy accordingly. The control unit (12) is configured to receive a plurality of signals corresponding to at least one parameter associated with the performance of the engine (11) from one or more sensors (1). The control unit (12) may be configured to determine torque generated by the internal combustion engine (11), based on the plurality of signals corresponding to the at least one parameter. In the illustrative embodiment, the control unit (12) is configured to determine a driving mode of the vehicle based on the received plurality of signals and the torque generated by the engine (11). The control unit (12) may determine the driving mode as the economy mode or the performance mode based on the at least one parameter of the engine (11) such as when the vehicle is driven at a constant engine speed or when the engine (11) generates low torque thereof.
In an embodiment, the control unit (12) may, then, compare the required torque with the torque generated by the engine (11). The control unit (12) may be configured to determine the fuel consumption of the engine (11) at the determined required torque and based on the performance of the engine (11) in the determined driving mode upon comparison of the required torque with the torque generated. The control unit (12) may be configured to regulate the fuel consumption by varying at least one parameter associated with the performance of the engine (11) in response to

the required torque of the engine (11), thereby switching the driving mode of the engine (11) from the determined driving mode, for example, from the economy mode to the performance mode or the cruise mode or vice versa thereof. In an embodiment, the control unit (12) may regulate the fuel consumption of the engine (11) by controlling the fuel injector (9) as best seen in Figure 1b.
In an exemplary embodiment, the control unit (12) may indicate to the user to manually switch the driving mode of the vehicle based on the comparison between the determined torque and required torque through at least one of a visual indication or an audio indication and the like.
In an embodiment, the control unit may be a centralised control unit of the vehicle or may be a dedicated control unit to the system (100) associated with the centralised control unit of the vehicle. The control unit (12) may also be associated with other control units including, but not limited to, body control unit, engine control unit, transmission control unit, and the like. The control unit (12) may be comprised of a processing unit. The processing unit may comprise at least one data processor for executing program components for executing user- or system-generated requests. The processing unit may be a specialized processing unit such as integrated system (bus) controllers, memory management control units, floating point units, graphics processing units, digital signal processing units, etc. The processing unit may include a microprocessor, such as AMD Athlon, Duron or Opteron, ARM’s application, embedded or secure processors, IBM PowerPC, Intel’s Core, Itanium, Xeon, Celeron or other line of processors, etc. The processing unit may be implemented using a mainframe, distributed processor, multi-core, parallel, grid, or other architectures. Some embodiments may utilize embedded technologies like application-specific integrated circuits (ASICs), digital signal processors (DSPs), Field Programmable Gate Arrays (FPGAs), etc.
The control unit (12) may be disposed in communication with one or more memory devices (e.g., RAM, ROM etc.) via a storage interface. The storage interface may connect to memory devices including, without limitation, memory drives, removable disc drives, etc., employing connection protocols such as serial advanced technology attachment (SATA), integrated drive electronics (IDE), IEEE-1394, universal serial bus (USB), fiber channel, small computing system interface (SCSI), etc. The memory drives may further include a drum, magnetic disc drive, magneto-optical

drive, optical drive, redundant array of independent discs (RAID), solid-state memory devices, solid-state drives, etc.
