Vdc off- subaro outback

[Noa Mire]

נדלקה לי נורה בלוח המחוגים שנקראת vdc off
ברכב סובארו אאוטבק. האם מישהו יודע מה הבעיה?
תודה

VDC זה מערכת בקרת יציבות או ESP אצל רוב היצרנים .
תבדוק שלא לחצת (או בד"כ אחרי ניקוי פנים) בטעות על לחצן ביטול המערכת.

בדגמים הישנים יותר של סובארו הלחצן היה מעל ברך שמאל (היכן שמכוונים מראות וזוית פנסי דרך).

רענן

היי רענן
לא מצאתי כפתור של esp או vdc.
יש לציין שאני באוסטרליה,וניסיתי להבין על פי ספר היצרן מה הבעיה,וצויין שם שיש בעיה במנוע. האם זה הגיוני?
תודה

לא הגיוני . צריך להיות לחצן בשם VDC .

Vehicle Dynamics Control
In the Outback 3.0 R VDC Limited, a sophisticated Vehicle Dynamics Control (VDC) stability system incorporates Variable Torque Distribution (VTD), All-Wheel Drive and an all-wheel, all-speed traction control system (TCS) to provide outstanding handling and control in all driving conditions. Controlled by VDC, the VTD centre differential – not the traction control system – determines power distribution.

VDC helps keep the car going where the driver steers it, using individual wheel braking, throttle control as well as centre differential clutch engagement to correct understeer (front-wheel drift) or oversteer (rear-wheel drift). TCS adds an extra margin of driving safety without impeding VTD All-Wheel Drive operation. The VTD system varies the power distribution to respond to traction conditions and vehicle dynamics.

Using special friction-estimation technology, VDC governs power distribution according to available surface friction. The system calculates traction based on sensor inputs and tire characteristics. This information provides finer control through more precise mapping of vehicle control parameters. In addition, the transfer torque ratio is controlled over a broader range.

Stability Control
VDC monitors vehicle stability by continually measuring inputs including steering angle, lateral-g, yaw rate, and individual wheel speed. Using this data, VDC can compare the driver’s intended path to the car’s actual path to detect understeer and oversteer conditions. Working with Variable Torque Distribution (VTD) All-Wheel Drive, VDC can correct understeer, oversteer and wheel slip.

Subaru designed VDC to increase stability on slippery surfaces and to increase cornering performance on dry roads. The system improves high-speed stability and helps prevent oversteer if the throttle is quickly lifted while cornering. Using various sensor inputs, VDC detects potential instability at either the front or rear of the vehicle. If VDC detects an unstable condition, it will produce a counteracting force to help restore stability by adjusting power distribution between the front and rear wheels and momentarily applying (or releasing) brake force on one or more wheels.

Traction Control
The VDC system also incorporates an all-wheel, all-speed traction control (TCS) function, which can apply a braking force to slow a slipping wheel or wheels. The system operates while driving in a straight line or cornering and helps maintain traction even if up to three wheels are slipping. If the driver is applying more throttle than available traction will allow, VDC will reduce engine power. It is important to point out that the Subaru VDC system uses traction control as a second line of defense, activated only when VTD alone cannot maintain sufficient traction.

All-Wheel Drive Operational At All Times
The Outback 3.0 R VDC Limited includes a “VDC Off ” switch to turn off the stability and traction control for driving in or extricating the vehicle from deep snow or mud. Under such conditions, the selective braking action that a stability or traction control system provides is not desirable. It is important to point out, however, that even with VDC off, the VTD All-Wheel Drive system operates at all times, and the standard viscous limited-slip rear differential is helpful for extricating the vehicle from deep snow.

How VDC Works
The VDC control module monitors various sensors (wheel speed, yaw rate, lateral-g) and evaluates the data to determine the vehicle’s direction. At the same time, the VDC control module receives driver inputs indicating steering angle and brake pressure to determine the driver’s intended direction. If there is a discrepancy between driver input and vehicle direction, VDC applies a corrective measure.

To correct understeer (front wheels don’t follow intended path), VDC applies braking force to the inside rear wheel. This counter-action pivots the car around the braked wheel and helps put it back on the driver’s intended course. At the same time, VDC optimizes All-Wheel Drive control by decreasing transfer clutch engagement to reduce power at the front wheels.

To correct oversteer (rear end slides out), VDC applies braking force to the outside front wheel. This counter-action pivots the car around the braked wheel to help bring the rear of the vehicle back in line. At the same time, VDC optimizes All-Wheel Drive control by increasing transfer clutch engagement to transfer more power to the front wheels. During an emergency lane change, for example, the quick change in direction could induce both understeer and oversteer. VDC responds by making continual adjustments to optimize stability and control.

VDC Advanced Logic
The Subaru VDC system responds to the varied conditions a driver might encounter on both dry and slippery surfaces. During straight-line acceleration, VDC controls engine output and braking of individual wheels (through TCS) and VTD All-Wheel Drive transfer clutch operation. During straight-line braking, the ABS function controls the braking action and the All-Wheel Drive transfer clutch operation.

Responding to oversteer with throttle depressed, VDC will:

Apply a strong brake force to the outer front wheel
Apply a slight brake force to the outer rear wheel
Increase transfer clutch engagement to transfer power to the front
Reduce engine output
Responding to oversteer with the brakes applied, VDC will:

Reduce brake force on the inner front wheel
Reduce brake force on the inner rear wheel
Increase brake pressure on the outer front wheel if the brake force applied by the driver is insufficient (in addition to the previous two steps)
Responding to understeer with the throttle depressed, VDC will:

Apply a slight brake force to the inner front wheel
Apply a strong brake force to the inner rear wheel
Reduce transfer clutch engagement to reduce power at the front wheels
Reduce engine output
Responding to understeer with the brakes applied, VDC will:

Reduce brake force on the outer front wheel
Reduce brake force to the outer rear wheel
Increase the brake force on the inner front wheel if the brake force applied by the driver is insufficient (in addition to the first two steps)
Increasing straight-line stability, VDC will:

Activate the centre differential clutches and lock the centre differential to stabilise the vehicle once it is driving in a straight line after a sharp steering manoeuvre. This takes advantage of the tendency for a vehicle with a locked centre differential to go straight.
Limited-Slip Rear Differential
For even greater traction capability, Subaru equips the 2005 Legacy 2.5 GT and all 2005 Outbacks with a viscous limited-slip rear differential. If one rear wheel starts to lose traction, the differential automatically diverts power to the other wheel. A limited-slip differential not only enhances traction on slippery road surfaces, but it is also a handling aid. For example, as the car enters a curve and weight transfers to the outside wheel, the inside wheel can lose traction. The limited-slip differential would, in this case, maintain the inside wheel’s speed making the vehicle more stable.

אם אני לא טועה, vdc זה הדיפרנציאל המרכזי. כך הוא נקרא בסובארו.

אז אתה טועה.
