Lateral Accelerometer: Description and Operation
G-SENSOR/LATERAL ACCELEROMETER
The G-sensor installed inside the Electronic Hydraulic Control Unit (EHCU) detects the vehicle deceleration speed and sends a signal to the
EHCU. In 4WD operation, all four wheels may be decelerated in almost the same phase, since all wheels are connected mechanically.
This tendency is noticeable particularly on roads with low friction coefficient, and the Anti-lock Brake System (ABS) control is adversely affected.
The G-sensor judges whether the friction coefficient of road surface is low or high, and changes the EHCU's operating system to ensure ABS
control.
