Control With G-Sensor - Mitsubishi Eclipse Technical Information Manual

Control with G-sensor

Since four wheels are connected in AWD models,
the four wheels may decelerate almost in phase.
This tendency is especially strong on a low frictional
resistance road; suspected vehicle speed does not
match actual speed, the road is judged to be a
high frictional resistance road and the ABS control
becomes unreliable. At such a time, the G-sensor
distinguishes* between low frictional resistance road

and a high frictional resistance road and makes
the ABS control reliable by switching the method
of calculating suspected vehicle speed.
When braking on a low frictional resistance road,
the rate of vehicle deceleration is slow. On the '
other hand, when braking on a high frictional
resistance road, the rate of vehicle deceleration
is fast.
