SYSTEM DIAGRAM
SYSTEM DESCRIPTION
• Side slip or tail slip may occur while driving on a slippery road or intending an urgent evasive driving maneu-
ver. VDC function detects side slip status using each s ensor when side slip or tail slip is about to occur and
improves vehicle stability by brake cont rol and engine output control during driving.
• In addition to ABS function, EBD function and TCS functi on, target side slip amount is calculated according
to steering operation amount from steering angle sensor. By comparing this information with vehicle side slip
amount that is calculated from information from yaw rate/side G sensor and wheel sensor, vehicle driving
conditions (conditions of understeer or oversteer) are judged and vehicle stability is improved by brake force
control on all 4 wheels and engine output control.
• VDC function can be switched to non-operational status (OFF) by operating VDC OFF switch. In this case,
VDC OFF indicator lamp turns ON.
• Control unit portion automatically improves driving stability by performing brake force control as well as
engine output control, by transmitting drive signal to actuator portion according to difference between target
side slip amount and vehicle side slip amount
VDC function is operating OFFOFF

SYSTEM
VDC Function That Prevents Understeer Tendency
• During cornering, brake force (brake fluid pressure) is applied on front wheel and rear wheel on the inner
side of turn. Momentum is generated directing the vehicle toward the inner side of the turn. Understeer is
prevented.
• Applying brakes during cornering on a slippery road, when there may be a tendency to understeer, engine output is controlled as well as brake force (bra ke fluid pressure) of 4 wheels. Understeer tendency
decreases.

• By preventing wheel lock through brake force (brake flui d pressure) control that is electronically controlled by
detecting wheel speed during braking, stability during em ergency braking is improved so that obstacles can
be easily bypassed by steering operation.
• During braking, control units calculate wheel speed and pseudo-vehicle speed, and transmit pressure
increase, hold or decrease signals to actuator portion according to wheel slip status.
• The following effects are obtained by preventing wheel lock during braking:
- Vehicle tail slip is prevented during braking when driving straight.
- Understeer and oversteer tendencies are moderated during brak- ing while cornering.
- Obstacles may be easily bypassed by steering operation during
braking.
• CONSULT can be used to diagnose the system.
• Fail-safe function is adopted. When a malfunction occurs in ABS function, the control is suspended for VDC function, TCS function
and ABS function. However, EBD function operates normally.

• By preventing rear wheel slip increase through rear wheel brake force (brake fluid pressure) control that is
electronically controlled when slight skip on front and rear wheels are detected during braking, stability dur-
ing braking is improved.
• EBD function is expanded and developed from conventional ABS function and corrects rear wheel brake force to appropriate level by electronic control according to load weight (number of passengers).
