What is a Vgrs light?

VGRS – Variable Gear Ratio Steering System. On VGRS equipped models this adjusts the wheel turning angle at low speeds. Light flashing – This is common after the battery has been disconnected, the system has been reset and is safe to drive.

What is Vgrs Lexus?

Lexus is preparing to issue a recall of Lexus LS models equipped with Variable Gear Ratio Steering (VGRS): VGRS is a feature that enables easier handling during low-speed driving and provides better stability during high-speed driving than conventional steering by changing the gear ratio.

What is Vgrs in Lexus lx470?

This bulletin describes the initialization procedure for the VGRS (Variable Gear Ratio Steering) system, which variably controls the steering angle in accordance with the vehicle speed.

How does variable ratio steering work?

In a variable ratio system, the closer you are to the “on centre” position, the less the road wheels move (change in angle) for a given steering wheel movement. As you get closer to full lock, the change in angle at the wheel is much greater, for the same movement of the steering wheel.

What is Lexus Dynamic Handling system?

The system fitted to this top-spec GS is called Lexus Dynamic Handling (LDH) and it coordinates a number of independent systems to sharpen the handling control and agility of both the front and rear wheels. It uses this data to determine the optimum steering angle for the rear wheels.

What is variable gear ratio steering?

Variable-ratio steering Variable-ratio steering is a system that uses different ratios on the rack in a rack and pinion steering system. At the center of the rack, the space between the teeth are smaller and the space becomes larger as the pinion moves down the rack.

What is a good steering ratio?

In most passenger cars, the ratio is between 12:1 and 20:1. For example, if one complete turn of the steering wheel, 360 degrees, causes the wheels to turn 24 degrees, the ratio is then 360:24 = 15:1. Larger and heavier vehicles will often have a higher steering ratio, which will make the steering wheel easier to turn.

How do you adjust the steering ratio?

To change the steering ratio, you have to Steering gear change. This means that a completely different steering gear has to be installed. However, it is questionable whether the installation of a different steering gear, which is not installed as standard by the manufacturer, is permitted in public road traffic.

What is Dynamic Rear Steering?

At speeds below 50mph the front and rear wheels turn in opposite directions; above this speed they turn in the same direction — to a maximum of 1.5 degrees. While this might appear counterintuitive, it actually makes for excellent control and precision, underpinned by safety and stability.

How many times should a steering wheel turn?

It’s about 3 turns for most road cars, between full left lock and full right lock – about 1080 degrees. Sportier cars have “quicker” steering racks with a smaller lock-to-lock rotation.
