#1 of 3 VSC - Vehicle Stability Control - What does it do?
Jun 22, 2008 (1:13 pm)
I have an '08 Avalon Ltd. and I don't believe I have VSC. So I'm curious, what does it do? When driving what would be the difference in feel between a car with VSC and one without? Also, under the car, what type of parts are involved and is it something that can be added without remaking the car?
Let me add that I've had my '08 Avalon for 4 months and have over 7,000 miles on it. I've driven it over the Rockies (both interstate and non-interstate in Colorado, New Mexico, and Utah) and flat land (Kansas, Texas, Oklahoma, etc.) and I am extremely pleased with the way it handles in all situations. It is a great driving automobile. I live in Arkansas where we have a combination of flat and hilly. So I curious what I'm missing.

In general VSC is totally unobtrusive and will not have any effect on ordinary driving. On the other hand if VSC detects under or overstearing it will activate and take action.
For over-stearing it will generally dethrottle the engine and apply braking to the front wheel outside of the "skid", or if you're already on the brakes it will "unbrake" the inside wheel. With understearing/plowing it will apply both rear brakes dethrottle the engine.
These are, will be, only momentary actions and will generally be over, having successfully corrected the circumstance, or not, by the time your mind realizes the VSC alarm has tripped..
VSC is really just an add-on feature to ABS & Trac, once you have those all you need is a yaw sensor and a stearing wheel rotational position sensor. Oh, and one hell of lot of additional firmware.
