Star Safety SystemTM
Enhanced Vehicle Stability Control provides cooperative control of the ABS, TRAC,
VSC and EPS.
Enhanced VSC helps to maintain directional stability when loss of tracti\
on occurs
during a turn.
Enhanced Vehicle Stability Control (VSC)
Anti-Lock Brake System (ABS)
Brake Assist (BA)
ABS helps prevent brakes from locking up by "pulsing" brake pressure to \
each
wheel. This limits brake lockup and helps provide directional control for the
current road conditions.
Toyota's ABS sensors detect which wheels are locking up and limits wheel lockup b\
y
"pulsing" each wheel's brakes independently. Pulsing releases brake pressure
repeatedly for fractions of a second. This helps the tires attain the traction that
current road conditions will allow, helping you to stay in directional control.
Brake Assist is designed to detect sudden or “panic” braking, and then a\
dd braking
pressure to help decrease the vehicle’s stopping distance. When there’s only a split
second to react, Brake Assist can add additional brake pressure more quickly than
just the driver alone can. VSC helps prevent loss of traction during cornering by reducing engine p\
ower, and
Traction Control helps maintain traction on loose gravel and wet, icy, or uneven
surfaces by applying brake force to the spinning wheel(s).
Toyota’s TRAC sensors are activated when one of the drive wheels starts to slip.
TRAC limits engine output and applies the brakes to the spinning wheel. \
This
transfers power to the wheels that still have traction to help keep you \
on track.
Traction Control (TRAC)
Electronic Brake Force Distribution (EBD)
Toyota’s ABS technology has Electronic Brake-force Distribution (EBD) to help
maintain control and balance when braking. Abrupt stops can cause a vehicle to
tilt forward, reducing the braking power of the rear wheels. EBD respond\
s to
sudden stops by redistributing brake force to enhance the braking effect\
iveness of
all four wheels.
SAFETY AND EMERGENCY FEATURES
All new Toyota vehicles come standard with the Star Safety SystemTM, which
combines Vehicle Stability Control (VSC), Traction Control (TRAC), Anti-lock Braking
System (ABS), Electronic Brake-force Distribution (EBD), Brake Assist (BA) and
Smart Stop Technology (SST).
