1. Chapter 1
Introduction

2. Definition Chassis: All vehicle structures except body and engine
Chassis Components:
Chassis Beam
Steering System
Braking System
Suspension System
Tire and Wheel
Driveline (gearbox, propeller shaft, drive shaft)

3. Basic Vehicle Motions 6 Basic Motions of a Vehicle: Roll Motion
Pitch Motion
Vertical Motion
Yaw Motion
Lateral Motion
Longitudinal Motion

4. Vehicle Roll
Steering input from the driver or asymmetric road profile between left and right tires can cause the vehicle to roll
Excessive roll angle can cause the vehicle to rollover
Disadvantages of vehicle roll: reduces stability and safety, driver can loss control of the vehicle; and reduces passenger comfort

5. Vehicle Pitch
Braking/throttle inputs from the driver or asymmetric road profile between front and rear tires can cause the vehicle to pitch
Disadvantages of vehicle pitch: reduces stability and safety, driver can loss control of the vehicle; and reduces passenger comfort

6. Vehicle Yaw
Yaw angle: the difference between the direction of vehicle forward speed with the direction of travel
Steering input from the driver, side wind force, asymmetric road friction can cause the vehicle to yaw

7. Vehicle Lateral Motion
Vehicle will move laterally under steering input from the driver
Lateral Maneuvers: lane change, cornering, collision avoidance, etc.

8. Longitudinal Motion
Throttle or braking inputs from the driver can cause the vehicle to move longitudinally
Longitudinal maneuver: accelerating or decelerating

9. Vertical Motion
Vertical motion of the vehicle reduces vehicle comfort level
Road input, steering input, brake input and throttle input can cause the vehicle to move vertically

10. Body Center of Gravity
How to determine the location of the body center of gravity of a vehicle???
