Hello Guys I learned about a new technology in cars. The all wheel steering system, the name itself gives us the idea about this system. Normally cars steer with the help of front axle tyres. In this system the rear tyres also steer accordingly when required. First car to have this technology is Honda Prelude.
The traditional steering i.e the front wheel steering is the basic steering type available on all cars. The working is very simple the car front turns where the front wheels are pointed, and the rear gets dragged along for the ride.
All Wheel Steering
In this system all four wheels turn at the same time when the driver steers. The rear wheel steering is controlled by computers and actuators. The degree of rear wheel turning is less than compared to the front wheels.
Working of All Wheel Steering
In the case of All wheel steering it depends on the situation. If you drive along the high speeds the rear wheel will steer in the same direction has the front wheel with low degree of turn. This helps in changing lanes, cause it is more of shifting than turn and correcting the wheel angle.
The situation changes at low speeds, the rear wheels turn at opposite direction at a lesser degree compared to the front wheels. This helps in maneuvering the car better at tighter corners and a better turning radius. It really helps in tight parking space with very low effort.
This cannot be done at high speeds because their will be stability issues. Here the computer comes in play that manages the rear wheel steering according to the situation. This system also helps while hard braking, the rear tyres toe-in to generate more braking power and stabilize the vehicle.
