Today’s cars are equipped with increasingly sophisticated
equipment to help you avoid an accident, but there are still
times when a collision becomes inevitable. Airbag deployment,
pre-tensioning of seatbelts, decoupling of pedals and the
absorption of impact forces in defined crumple zones all help
protect the driver and passengers, but lives could be saved
and injuries could be lessened if certain safety systems were
activated immediately before an impact, rather than after
Toyota is making a major advance in driver and passenger protection
with the development of Pre-crash Safety, a system that recognises
when a collision is going to happen. The timing involves just
fractions of seconds, but that can be enough to prevent serious
injury or even death.
The Toyota Pre-crash System comprises three core elements:
- Toyota developing Pre-crash Safety, intelligent technology
which can predict a crash and launch safety systems ahead
of an impact
- Millimetre-wave radar determines unavoidable collisions
with other traffic and obstacles
- Triggering of seatbelt retractors and brake assist before
an impact increases passenger protection and potentially
reduces accident injuries and fatalities
- Pre-crash Safety part of Toyota’s wider programme
of Intelligent Transport Systems research and development
- Potential application of new technology in production
models during 2003
- The Pre-crash sensor, a millimetre-wave radar that detects
vehicles and obstacles ahead
- Pre-crash driver and front passenger seatbelts that retract
as soon as a collision is identified
- Pre-crash brake assist which increases braking pressure
as soon as the driver begins to depress the brake pedal
