4-WHEEL ANTI-SKID BRAKING SYSTEM (4ABS)
FEATURES
ABS has been adopted as optional equipment in
RS-II to maintain directional stability and steering
performance during sudden braking or braking on
slippery road surfaces.
The ABS control method is a 4-sensor, 4-channel
method which provides independent control for all
wheels.
Following system for Lancer EVOLUTION-VII has
been modified from Lancer EVOLUTION-VI Tommi
Makinen Edition.
D
By adding lateral G sensor, longitudinal G
sensor and steering wheel sensor, optimized
ABS control at the time of cornering.
D
By inputting parking brake switch signal to
ABS-ECU with pulling parking brake lever, ABS
control has been optimized.
D
ABS-ECU outputs ABS signal to 4WD-ECU.
D
G sensor (lateral), steering wheel sensor and
parking brake switch have been added to the
diagnosis and service data.
D
ABS-ECU connector has been changed.
EBD CONTROL
In ABS, electronic control method is used by which
the rear wheel brake hydraulic pressure during
braking is regulated by rear wheel control solenoid
valves in accordance with the vehicle’s rate of
deceleration and the front and rear wheel slippage
which are calculated from the each wheel speed
sensor’s signal. EBD control is a control system
which provides a high level of control for both vehicle
braking force and vehicle stability. The system has
the following features:
D
Because the system provides the optimum rear
wheel braking force regardless of the vehicle
laden condition and the condition of the road
surface, the system reduces the required pedal
depression force, particularly when the vehicle
is heavily laden or driving on road surfaces
with high frictional coefficients.
D
Because the duty placed on the front brakes
has been reduced, the increases in pad
temperature can be controlled to improve the
wear resistance characteristics of the pad, dur-
ing front brakes applying.
D
Control valves such as the proportioning valve
are no longer required.
