Vehicle
Dynamics
,Drive Train for Petrol Vehicle
Power required to drive a Vehicle (ICE & EV) and Energy required to travel a
particular distance depends on
• Composite mass of the vehicle (including passenger and goods)
- Gross Vehicle Weight (GVW)
• Condition of the roads (rolling resistance)
• Aerodynamics of the vehicle (Aerodynamic drag)
• Incline that it needs to traverse (Gradient Resistance)
• Velocities and accelerations at different points of time (Drive Cycle)
• Maximum speed and maximum acceleration of the vehicle
, Tractive forces acting on a Vehicle
Aerodynamic Drag
- resistance offered by the air to the movement of the body
Rolling Resistance
- force resisting the motion when a body rolls on a surface
Uphill Resistance
- Component of weight working in a direction opposite to its motion, w
the vehicle travels uphill
Acceleration
- To move forward at a particular speed
