The four-wheel steering is the rear wheel with the front wheel with steering. High speed when traveling on four wheels is transferred in one direction, you can understand the trend of pan to another lane for vehicle lane changes. When turning, the rear wheel turning reverse, this can greatly reduce the radius of the turn.
In fact, the four-wheel steering is not a complicated concept, know its invention Who, for you, this is meaningless. The most difficult to effectively implement this concept, so bring enough benefits, in order to find justification for the cost of the new. Manufacturers may do so for the first time Mercedes Sri Lanka - Mercedes-Benz. 1938 Mercedes - Benz created an off-road military vehicle, named 170VL Reverse front wheel of the car through the rear-wheel steering, in order to shorten the turning radius. But Mercedes Adams never used road bike the four steering system. The first mass production cars of four-wheel steering road vehicle is a 1985 Nissan Skyline (not GT-R). And Mercedes models is not the same, the vehicle is through the rear wheels in the same direction with the front wheels for steering, the steering angle of a maximum of 0.5 degrees, which formed on the stability of a strong auxiliary. Skyline system does not meet the definition of four-wheel steering, the car simply by hydraulic power to the entire rear suspension mounting subframe steering.
So, the first authentic production of four-wheel steering models Honda Prelude (1987 model year). The most special thing and is also a registered patent innovative technology: rear-wheel steering angle depends on the angle of the front wheels. When turning the steering wheel, the first rear wheel rear wheel is rotated slightly in the same direction as the front wheel by up to 1.7 degrees. This improves driving stability when the high-speed steering or change lanes. Continue direction sharply turning the steering wheel will reverse the rear wheels. This operation can be used to enhance the response when the low-speed bending. The following figure shows this feature.
Four-wheel steering - poured into a bad
From the late 1980s to the present day, the Japanese car manufacturer continues the tradition of independent four-wheel steering. Western car manufacturers seems to have little interest in (and there are rumors that Audi is its the A8 cars developed four steering system, but it did not), since the 1990s, and even the Japanese themselves began to lose interest in their new models to give up the use of four-wheel steering system. To when I wrote this text, the Japanese are no longer producing any four bogie.
By the threat of electronic stability control and yaw control system for four-wheel steering, the two devices are the same as the four-wheel steering system to correct understeer / oversteer, without causing excessive increase in cost and weight adversely affected.
The Skyline The Super HICAS
However, the Nissan Skyline GT-R are still prove to the world four-wheel steering is challenging jiakong characteristics value. Super HICAS system through computer-assisted Nissan enabled the skates tightly controlled brake, this form can be an alternative means to see them through. When you are faced with the challenges of corners, the rear wheels will be the first reverse steering, in order to enhance the sensitivity of the initial steering response. Then, when the sensor is sensitive to the automotive respond to steering maneuvers, the rear wheel will shift in the same direction as the front wheels, which immediately import rear tire sliding response, this response may help to adjust the angle of attack bending. Excessive amount of computers in monitoring the entire process, steering will always be suppressed. You do not need to worry about losing control.
