ECB translates brake pedal pressure into electric signals that, via computer control, help provide precise and optimized braking in virtually any traction condition. Electronic control provides quick brake response when needed, helping the VDIM system to anticipate and help correct slides before they might occur. The ECB system is backed by conventional hydraulic brake control in case of the unlikely event of electronic failure.

VDIM integration strategy provides precise control for the ECB, Electric Power Steering (EPS), Vehicle Stability Control (VSC), ABS, Brake Assist (BA), Electronic Brakeforce Distribution (EBD) and engine torque via the electronically controlled throttle. On Lexus LS 460 L, GS 430 and GS 450h models, VDIM also influences Variable Gear Ratio Steering (VGRS) to affect minor steering corrections when needed.

Electric Power Steering
Electric Power Steering (EPS) in VDIM-equipped Lexus models provides precise electric power assist using a DC motor built into the steering gear housing, rather than traditional hydraulic assist. Eliminating the hydraulic steering pump reduces engine drag, and the simplified Lexus steering system is lighter and more compact than hydraulic power steering systems.

The VGRS system in Lexus LS 460 L, Lexus GS 430 and Lexus GS 450h models is a further development of the technology featured on the Lexus LX 470 luxury utility vehicle. VGRS electronically adjusts the steering ratio according to vehicle speed. In Lexus LS 460 L, Lexus GS 430 and Lexus GS 450h, VGRS can vary the steering from 2.7 turns lock-to-lock for low-speed maneuverability to a slower 3.2 turns lock-to-lock for highway-speed stability. (By comparison, Lexus GS 350's hydraulic power Lexus steering system uses a constant 3.2 turns lock-to-lock.) Additionally, VGRS provides differential steering control, which helps correct for a delay in steering response, something that occurs in all vehicles. This function helps enhance driving feel in lane changes and other transitional maneuvers.

Adaptive Variable Suspension
The Adaptable Variable Suspension (AVS) system is standard on Lexus LS 460 L, GS 430 and GS 450h sedans and Lexus GX 470 and Lexus LX 470 luxury utility vehicles. Responding to road conditions, driver input and vehicle speed, AVS continuously adjusts the shock absorber damping force to help provide the best balance of ride comfort and handling response. For the GX and LX, the driver can select from normal, comfort and sport settings; for Lexus LS 460 L, Lexus GS 430 and Lexus GS 450h, there are two selections: normal and sport.


Comfort and Convenience

Active-Control Engine Mount
In Lexus ES 350 sedan and the RX luxury utility vehicles, an active engine mount helps keep even the smallest vibrations from reaching the passenger compartment. A solenoid-controlled diaphragm produces pulses equal-to-but-opposite those of the engine, helping to dampen vibration with every power stroke.

Rear Back-Up Camera
All 2007 Lexus models offer a rear back-up camera that provides an extra measure of confidence when reversing the vehicle. The rear back-up camera is standard in the LX 470 luxury utility vehicle, LS 460 L, and Lexus GS 450h hybrid sedan. In all other models, it is part of the available navigation system. The camera gives the driver a view of what its lens can detect behind the vehicle, projecting a color image onto the central display screen when reverse gear is engaged.

Dynamic Laser Cruise Control
Lexus RX 350 and Lexus RX 400h models offer available Dynamic Laser Cruise Control This system uses lasers to collect data from scanning points ahead and is designed to help the driver automatically maintain a set distance from the vehicle traveling in front.
