Condition Safety Flashcards
1
Q
Definition: Condition safety
A
All measurements which optimize and preserve the condition (physical, mental/psychological fitness) of the driver
2
Q
Condition Safety (list):
A
- Driver assistance reducing workload of driving
- Seat design and properties
- Climate in the vehicle
- Vehicle acoustics
- Visibility conditions
- Vibration comfort
3
Q
Air-conditioning (list)
A
- Vigilance
- Misting & icing prevention
- Thermal comfort
- Air quality & hygiene
4
Q
Examples of the effect of heat stress on driving:
A
- Decreased perception and attention impair driver action
- Missing and overhearing signals
- Decreased attention to secondary tasks, e.g. observing speed, emergency vehicle horns, flashing light signals
- Increase in reaction time (by approx. 22% when the interior temperature rises from 21°C to 27°C) [TAX99]
- Decreasing visual performance (Visual acuity decreases linearly with the increase in body temperature)
- Agressive driving behaviour (e.g. determined by drivers’ honking behaviour).
5
Q
Demands on Vehicle Glazing
A
- Safety
- Comfort
- Information medium
- Recycling
- Lightweight
- Rigidity / Stiffness
- Aerodynamic
- Acoustic
- Design
6
Q
Properties of CSG (Composite Safety Glass)
A
+ Cohesive after breakage (stone impact)
+ Improved break-in safety
+ Less danger of ejection in case of an accident
+ Sound damping
+ Ushering in a new dimension of functions (sensor technology)
- Costs
- Weight
- Cohesivness
CSG - mainly in windscreens
SSG - mainly side and rear windows

- pressure distribution
- first sitting feeling
8
Q
Vehicle Seats: Integration / realization
A
- constructed space
- adjustability
- carsh-safety
- costs
- weight
- mechanical stability
