5.2 Service Electronic Brake System
5.2.1 Anti-Lock Braking System (ABS)
Anti-lock braking system (ABS) is an important
part of active safety system.
When ABS works, the friction between the
wheel and the road belongs to rolling friction and it
is favorable for braking by making use of maximum
adhesion between the wheel and road, thereby
improving the braking deceleration, shortening the
braking distance, and ensuring the direction
stability in the process of vehicle braking.
The ABS operation is equivalent to snubbing at
a high frequency. The driver will feel the vibration of
brake pedal accompanied by the “tick” sound
produced by brake master cylinder operation when
depressing the brake pedal in emergency. In this
case, the ABS is in normal working state. Since the
brake master cylinder adjusts the brake pressure
constantly, a force will be fed back to the brake
pedal continuously. Therefore, in this case, it is
required to depress the brake pedal to the end, and
it is forbidden to depress the brake pedal
repeatedly.
As ABS is only the safety assistant system, its
function is very limited. For example, when making
a brake on sand and stone road or snowy road, it
may have a longer braking distance compared with
braking on concrete road or dry road. Don't take it
for granted that ABS can get ideal brake
performance in any situation. Therefore, do not rely
on these systems too much. Only safe driving is the
most important.
Under the following conditions, light depress
the brake pedal to activate ABS. It is normal to feel
vibration:
•
When shifting gears.
• During emergency braking.
• When turning at high speed.
• When driving on slippery road.
• When driving on projected or pit road.
• When making sudden start after the vehicle is
started.
