Figure 8 illustrates a method 800 of operating the auto-temperature controlled seat, in accordance with an embodiment of present disclosure.
At 802, the method 800 comprises receiving, via a temperature control switch, a user input to control temperature setting using a temperature control assembly embedded within the seating assembly. The user input is received via a switch on the seat or the starting of two-wheeler vehicle. In response to the user input, the power supply is switched on.
At 804, the method 800 comprises receiving, via one or more inlet holes at the surface of the seat base layer, air to be heated or cooled.

At 806, the method 800 comprises adjusting the temperature setting for the seating assembly by circulating air throughout seating area of the seating assembly based on controlling a fan module provided within a seat cushion layer above a seat base layer, wherein adjusting the temperature setting further comprises heating or cooling input air, received from the environment, via the fan module coupled with at least one of a heat sink and a cool sink of a semiconductor module.

In an embodiment, one or more inputs may be provided, by the semiconductor module, to the control unit for controlling a fan driver, which controls the fan module. The temperature setting adjustment may be controlled, by an electronic control unit (ECU) of the vehicle/seat assembly, the fan driver and semiconductor as per the inputs provided by the user. In another embodiment, the ECU may control the fan driver and semiconductor automatically without any manual inputs and based on predefined instructions stored within a memory at the ECU.
In one embodiment, at step 806, the method 800 further comprises passing, via at least one air duct, the heated or the cooled air from the fan module to a seat surface of the seating assembly. In one embodiment, the fan drivers may provide the appropriate speed and power to the fan module. In response, the fan module may provide air as per requirements to seating area through ducts connected via semiconductor module.
In one embodiment, the step 806 further comprises circulating, via a first spacer fabric layer above the seat cushion layer, the heated or the cooled air throughout seating area of the seating assembly. In an embodiment, a second spacer fabric may be integrated with and over the at least one air duct to prevent piercing of the at least one air duct.

Figure 9 illustrates peltier module for the auto-temperature controlled seat assembly, in accordance with an embodiment of present disclosure. The seat assembly discussed throughout the present disclosure may utilize a peltier effect module for controlling temperature of a seat surface of the assembly. As is widely known, the cooling of one junction and the heating of the other junction when electric current is maintained in a circuit

of material consisting of two dissimilar conductors; the effect is even stronger in circuits containing dissimilar semiconductors.
The Peltier semiconductor is present in the semiconductor module. As per the inputs received from the ECU to the semi-conductor module, the semiconductor/Peltier effect is triggered. If a signal/input received is indicative of cooling the seat assembly, then the semiconductor heats from the exhaust air side and cools from the air circulation side. The air from the fan module is driven accordingly and vice-versa as the case for heating module.
The fan module is coupled with the semi-conductor module. The semiconductor module has two semiconductors which are connected to each other. When electricity is passed through these semiconductors, there is generation of heat at one side and generation of cooling at the other side. Thus, as per requirement the heated/cooled air can be passed via the fan module to the seating area. When the polarity is reversed, the heated side becomes cold and vice-versa. Thus, in this way, the heat-sink or a cool-sink present in the semi-conductor module heats or cools the seat.
Since peltier module’s generic functioning is well known, it is not discussed in detail for the sake of brevity, while the unique aspects of peltier module have been discussed in detail above.
The present disclosure provides several technical advancements as the fitment of the temperature-controlled kit in the seat assembly is performed in a manner which is convenient for the rider as well as passenger during riding. In other words, there is no discomfort caused to the rider and the passenger due to the innovative way of fitment of the components of the seat assembly. Further, the seating assembly provides for an efficient way of heating/cooling the seat for passengers by way of a control switch fitted on the seat assembly, and also providing a unique way of controlling exhaust air, as discussed above. Additionally, the circulation of air through the layered assembly provides a cooling/heating effect seamlessly

and efficiently for the riders/passengers over the conventional methods of providing air to the outside of seat assembly.
While specific language has been used to describe the present subject matter, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein. The drawings and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment.
