Vehicle dynamics | EPFL Graph Search

For motorized vehicles, such as automobiles, aircraft, and watercraft, vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics. The aspects of a vehicle's design which affect the dynamics can be grouped into drivetrain and braking, suspension and steering, distribution of mass, aerodynamics and tires. Automobile layout (i.e. location of engine and driven wheels) Powertrain Braking system Some attributes relate to the geometry of the suspension, steering and chassis. These include: Ackermann steering geometry Axle track Camber angle Caster angle Ride height Roll center Scrub radius Steering ratio Toe Wheel alignment Wheelbase Some attributes or aspects of vehicle dynamics are purely due to mass and its distribution. These include: Center of mass Moment of inertia Roll moment Sprung mass Unsprung mass Weight distribution Some attributes or aspects of vehicle dynamics are purely aerodynamic. These include: Automobile drag coefficient Automotive aerodynamics Center of pressure Downforce Ground effect in cars Some attributes or aspects of vehicle dynamics can be attributed directly to the tires. These include: Camber thrust Circle of forces Contact patch Cornering force Ground pressure Pacejka's Magic Formula Pneumatic trail Radial Force Variation Relaxation length Rolling resistance Self aligning torque Skid Slip angle Slip (vehicle dynamics) Spinout Steering ratio Tire load sensitivity Car handling Some attributes or aspects of vehicle dynamics are purely dynamic. These include: Body flex Body roll Bump Steer Bundorf analysis Directional stability Critical speed Noise, vibration, and harshness Pitch Ride quality Roll Speed wobble Understeer, oversteer, lift-off oversteer, and fishtailing Weight transfer and load transfer Yaw The dynamic behavior of vehicles can be analysed in several different ways.

Less Conservatism, Stronger Robustness: Iterative Robust Gain-Scheduled Path Following Control of Autonomous Bus With Unstructured and Changing Dynamics

Denis Gillet, Man Shi, Jianwei Li

Path-following control is a critical technology for autonomous vehicles. However, time-varying parameters, parametric uncertainties, external disturbances, and complicated environments significantly challenge autonomous driving. We propose an iterative rob ...
