CAE Automotive Safety Systems 1 — Questions and Answers
Question 1: What is the Federal Motor Vehicle Safety Standard (FMVSS) 208?
- The standard governing occupant crash protection, including airbag and seatbelt requirements (Correct answer)
- A fuel economy regulation
- An emissions testing standard
- A tire pressure monitoring requirement
Correct answer: The standard governing occupant crash protection, including airbag and seatbelt requirements
FMVSS 208 establishes performance requirements for occupant protection in frontal crashes, mandating airbags, seatbelts, and their performance criteria in crash testing.
Question 2: How does Electronic Stability Control (ESC) prevent loss of vehicle control?
- By automatically applying individual brakes and reducing engine power when sensors detect the vehicle is skidding (Correct answer)
- By locking all four wheels during emergency braking
- By increasing tire pressure during high-speed turns
- By activating the parking brake during slides
Correct answer: By automatically applying individual brakes and reducing engine power when sensors detect the vehicle is skidding
ESC uses wheel speed sensors, steering angle sensors, and yaw rate sensors to detect when a vehicle begins to lose traction, then selectively applies brakes to individual wheels to correct the vehicle's path.
Question 3: What is a crumple zone in vehicle design?
- A structural area designed to deform and absorb crash energy, protecting the passenger compartment (Correct answer)
- A reinforced area that remains rigid during a crash
- A soft interior padding material
- A breakaway engine mount system
Correct answer: A structural area designed to deform and absorb crash energy, protecting the passenger compartment
Crumple zones are engineered to progressively deform during a collision, absorbing kinetic energy and extending the crash duration, which reduces the forces transferred to occupants in the passenger safety cell.
Question 4: What does ADAS stand for in automotive safety?
- Advanced Driver Assistance Systems (Correct answer)
- Automotive Design and Safety Standards
- Automatic Driving Acceleration System
- Anti-Distraction Alert Software
Correct answer: Advanced Driver Assistance Systems
ADAS encompasses technologies like adaptive cruise control, lane departure warning, automatic emergency braking, and blind-spot monitoring that assist drivers and reduce the risk of accidents.
Question 5: What is the purpose of crash test ratings from NHTSA and IIHS?
- To evaluate and rate vehicle safety performance in standardized crash tests, helping consumers make informed choices (Correct answer)
- To determine insurance premiums only
- To certify vehicles for export
- To set manufacturing quality standards
Correct answer: To evaluate and rate vehicle safety performance in standardized crash tests, helping consumers make informed choices
NHTSA (5-star ratings) and IIHS (Good, Acceptable, Marginal, Poor) conduct independent crash tests simulating real-world collision scenarios to assess how well vehicles protect occupants.
Question 6: What is the function of a tire pressure monitoring system (TPMS)?
- To alert the driver when tire pressure drops below safe levels, preventing blowouts and improving fuel efficiency (Correct answer)
- To automatically inflate tires while driving
- To measure tire tread depth
- To control the vehicle's suspension system
Correct answer: To alert the driver when tire pressure drops below safe levels, preventing blowouts and improving fuel efficiency
TPMS uses sensors to monitor air pressure inside each tire and alerts the driver via a dashboard warning light when pressure drops below the recommended level, mandated by FMVSS 138 since 2007.
