TORRANCE, Calif—Lexus announced this week the introduction of its new handling technology system, Vehicle Dynamics Integrated Management system (VDIM), in the 2006 GS 430 luxury sport sedan.
VDIM enhances handling and traction control systems that normally react to an already unstable condition by anticipating tire slippage before a skid, slide or wheel spin occurs.
VDIM uses a range of sensors including steering angle, yaw rate, deceleration, brake pressure, brake pedal stroke, wheel speed and others. These signals are used individually by the various traction control systems and collectively by VDIM. Data is gathered from more sources and processed earlier and faster than previous designs, according to Lexus.
These systems include Vehicle Stability Control (VSC), Traction Control (TRC), Brake Assist (BA), Anti-Lock Brakes (ABS) and Electronic Throttle Control with intelligence (ETC-i).
In addition, three new technologies work in tandem with VDIM: Electric Power Steering (EPS), Variable Gear Ratio Steering (VGRS) and Electronically Controlled Brakes (ECB).
