SERES SF5 - TCS, HAC, HBA, HAZ, and HDC

When the vehicle turns suddenly while driving, the
VDC system judges the driver’s driving intention
based on information such as the steering wheel
angle and vehicle speed, and continuously
compares it with the actual conditions of the vehicle.
If the vehicle deviates from the normal driving
route, the VDC will apply brakes to corresponding
wheels in order to make corrections to help the
driver control sideslip and keep the direction of the
vehicle stable.
TCS
TCS reduces the power of the motor to prevent the
wheels from slipping during acceleration, and
applies braking force control when necessary, in
order to prevent wheels from spinning. Under
unfavorable driving conditions, TCS can make the
vehicle easy to start, accelerate and climb. When
TCS effectively controls brake pressure and motor
power, an electronic stability control indicator is
displayed on the meter.
Warning
Traction control does not prevent accidents
caused by dangerous driving or sudden
steering at high speeds.
When on a slope, HAC will automatically hold the brake
for about 1.5s, which can prevent the foot slipping when
changing from the brake pedal to the accelerator. HAC
will automatically prevent the vehicle from slipping
back.
Warning
HAC will stop working after 1.5s, and the vehicle
can slide at this time. Therefore, please quickly
move your foot from the brake pedal to the
accelerator. Do not rely on the HAC for a long
time (more than 1.5 s), in order to prevent the
vehicle from sliding, otherwise it may cause a
collision.
When driver quickly steps on the brake pedal, HBA
can recognize that the vehicle is in an emergency
state and quickly increase the brake pressure to the
maximum value, so that ABS can intervene more
quickly and effectively shorten the braking distance.
HAZ
When the vehicle speed is faster than 50km/h, the
deceleration is faster than 6m/s² or the ABS is
triggered, driver will perform emergency braking.
When the ESC system recognizes that the vehicle is
in an emergency braking state, it will transmit the
emergency braking signal to the BCM controller to
light up the double flashing turn signal in order to
warn the following vehicles, which serves as a
hazard warning.
HDC controls the speed of the vehicle through
automatic braking intervention. With this system,
you do not need step on the brake pedal. Increasing
or decreasing the downhill speed can be achieved
by operating the accelerator, so that you can place
all your attention on the steering wheel. This
function is particularly useful when going down
steep slopes, especially on rugged and slippery
terrain.
However, you can still use the brake pedal to slow
down or stop the car at any time.
Warning
Decrease in braking effect is like all brakes,
braking ability is also affected by slippery roads
(for example, on icy roads or soft surfaces),
which may cause accidents.
