  • the IC engine may include a carburetor or a fuel injector, an ignition system, a valve timing system etc., which may be electronically operated. Further, an electrical machine of the IC engine, which is capable of operating as both a starter and a generator needs to be electronically controlled. Moreover, the vehicle includes many other electrical systems like a battery, which is an energy storage device, that is mounted thereon. A large sized controller may be required to control operations of all the electronic/electrical systems. Moreover, it is difficult to accommodate such large electronic controller in the saddle -ride vehicle due to space constraints in saddle - ride vehicle and due to heat dissipation issues.
  • the controllers are disposed behind the power unit.
  • the controllers along with other electrical components are disposed below the seat and the fuel tank.
  • the controller used for controlling the electrical machine is disposed below the fuel tank behind a cylinder portion of the IC engine.
  • the controller is disposed between a style panel and a swinging type power unit (especially in step-through type vehicles) towards one of the lateral sides. Because of which excessive heat from the power unit and the controller dissipates towards a step-through space where the rider rests his feet.
  • a battery and the controller are disposed ahead of a head tube covered by a front-style part. The controller is either on a right side or a left side of the battery. In such a configuration, heat from the battery and the controller flows towards the rider and towards rider hands making it uncomfortable for the rider to drive the vehicle. Additionally, the mass addition towards the front region disturbs the centre of gravity of the vehicle thereby adversely impacting the handling performance of the vehicle.
  • the controllers are unguarded during sideward impact or fall as they are unguarded by frame of the vehicle. Any damage to the controllers would leave the vehicle inoperable because damage to the controller controlling the electrical machine makes the IC engine devoid of startability. Any damage to the controller controlling the IC engine would make the IC engine impaired from functioning.
  • a kick-start lever is not provided as the high capacity battery can provide startability with reliability.
  • the rider would be left stranded with the vehicle irrespective of the high capacity battery being present. The user will not be able to take the vehicle to nearest service station resulting in customer dissatisfaction.
  • the ground-reach of the vehicle is poor. Because, the seat height is kept higher to accommodate the electrical components including the controllers. The increase in seat height from the ground affects the ground-reach for some riders causing discomfort as well as balancing concerns.
  • a vehicle includes style panels that are mounted to the frame.
  • the style panels are typically kept closer to the frame making it difficult to securely mount electrical components like controllers which will have minimal impact from sideward direction during a fall of the vehicle.
  • the risk of damage to controller is high, when the controllers are laterally facing outward.
  • the width of the vehicle must be increased, without increasing the seat height thereby creating space between the style panels and the controllers. In effect, when the width of the vehicle is increased, the ground-reach again gets affected causing discomfort to the rider and leading to design of a non compact vehicle as a compromise.
