Chrysler Group achieves safety through a three part, holistic safety approach

1. Education – Safety Programs designed to educate and raise awareness of high-risk behavior

2. Active Safety – Features designed to mitigate or reduce collision severity prior to an impact

3. Passive Safety – Features designed to protect the occupant after an impact

Electronic Stability Program (ESP)

• The potential for active safety lies in the avoidance or mitigation of accident severity

• Where passive safety allows milliseconds for decision making, active safety provides seconds

• One such feature is Electronic Stability Program (ESP), which is designed to assist the driver in maintaining directional control

• Due to the importance of active safety, there is a module dedicated to the emerging technologies used to in the development of ESP

CAE / Simulation Technology

• A full range of computer aided engineering (CAE) simulations have been employed in the development process

• The development process flow verifies safety at the component level first, systems, & ultimately the full vehicle
