EDVSM

EDVSM (tm) (Engineering Dynamics Vehicle Simulation Model) is a 3-D simulation of a motor vehicle to driver inputs (steering, braking, throttle and gear selection). Based on the HVOSM-VD2 model developed at Calspan, EDVSM also includes several enhancements developed by EDC. Using EDVSM, a vehicle may be simulated on virtually any surface. The program computes 3-D vehicle kinematics, tire forces and moments, suspension forces and deflections, drive and brake system torques and driver inputs.

EDVSM is used to predict and visualize vehicle response to driver inputs, especially for limit maneuvers resulting in loss of control and rollover. Version 1.10 of EDVSM also includes a "blown tire" model useful in accurately simulating the effect of either a sudden or gradual loss of tire pressure on vehicle handling.
