JAC A-CLASS, Manual

Page: 157 / 176

Three systems of a vehicle make it
to be driven to the destination.
These
systems include brake
system, steering system and
acceleration system. Three systems
must function at the position where
the tyres and road contact.
Sometimes, for example, driving on
a road covered with snow or water,
the requirements for these control
system exceed the scope that the
tyres and road can stand. That
means the vehicle may be out of
control.
Vehicle control
Brake
Control operation includes sensation
time and reaction time.
At first, you need to decide whether
to depress the brake pedal, this is
sensation time, and then you must
lift your foot and depress the pedal,
attention and judgment.
Drinking driving may result in
severe and even fatal traffic
accidents. Never drive after
drinking or travel in a vehicle
driven by a drunk driver.
this is reaction time.
Average reaction time is about 3/4
seconds, but this is only average
time. One driver may have very
short reaction time, while another
driver may have a reaction time as
long as 2 to 3 seconds, depending
on
age, physical conditions,
vigilantness, coordination and eye
sight.
Alcohol, drugs and dejection also
have impacts. Even if the reaction
time is 3/4 second, when a vehicle
runs at 100km/h, it will also go
ahead
20m. Under emergent
situations, this distance is too big.
Therefore, it is very important to
keep sufficient distance with other
vehicles.
Of course, actual brake distance
may vary depending on road surface
