FIELD OF THE INVENTION
[001] The present invention relates to a saddle type vehicle. More particularly, the present invention relates to disposition of a control unit in the saddle type vehicle.

BACKGROUND OF THE INVENTION
[002] As electric vehicles (EVs) continue to gain prominence in the automotive industry, optimization of their electronic control systems becomes important. An Intelligent Vehicle Control Unit (iVCU) is a critical component responsible for controlling the electronic control systems and for managing various vehicle functions. However, integration of iVCU within vehicle architecture faces significant challenges. Conventionally, the iVCU is positioned in proximity of a vehicle battery in the rear portion of the vehicle or below the seat assembly. However, both configurations present drawbacks that compromise the performance, serviceability, and overall balance of the vehicle.
[003] The conventional placement of the iVCU in proximity to the battery results in an imbalanced center of gravity (CG) due to uneven weight distribution in the rear portion of the vehicle. Further, positioning the iVCU below the seat assembly inhibits adequate heat dissipation, leading to potential damage to the unit. Furthermore, this leads to restricted airflow and limited heat dissipation capacity, increasing the risk of overheating and potential damage to the iVCU when placed below the seat assembly. Such a disposition of the iVCU also poses challenges in terms of accessibility and serviceability, as accessing the iVCU necessitates the removal of the entire seat assembly, thus increasing maintenance time and complexity. Additionally, positioning the iVCU in the rear portion of the vehicle results in uneven weight distribution, potentially affecting stability and handling characteristics of the vehicle.
[004] Moreover, finding a convenient location for both the iVCU and a battery of the vehicle represents quite a difficult task due to packaging constraints persisting in the saddle type vehicle. Problems are usually encountered during design of the wiring system, in particular for finding a convenient path for the electrical cables due to the packaging constraints in the saddle type vehicle.
