G-sensor
For the vehicle with the ABS, a speed
difference between the wheels is not
noticeable as all the wheels are slipping
during abrupt braking. Therefore, the vehicle
needs the speed information from other
sensors other than the wheel speed sensor.
On the 2WD vehicle, there is not large
difference between the vehicle speed
reduction and actual wheel speed reduction in
the event of braking since the driving wheels
are in the front. So, the ABS HECU can
control the vehicle, based on a calculation
value. But, on the 4WD vehicle, if a speed
reduction occurs in the front or rear of the
vehicle, it affects the other side wheel. In
other words, braking the rear wheels induces
also a large speed reduction in the front
wheels. The longitudinal acceleration sensor is
used for this case. It controls the ABS by
using the signals from the sensor during
abrupt braking and acceleration.
