All-wheel steering is not a new technology. This technology began to be used around 1980s, such as Porsche 9 1 1, Bugattica Long Xing, Lamborghini Huracan? High-end cars such as Evo have applications. In addition to high-end models, Citroen Fukang, as the "old three", has also used four-wheel steering. The four-wheel steering system on Fukang is not so complicated and high-tech, but the rear torsion beam suspension is unique in design and forms a soft connection with the car body. This four-wheel steering is also called rear wheel follow-up steering. Although it can improve some performance, it is limited.
In addition, there is a kind of rear wheel active steering, which is common in luxury cars, such as BMW 7 Series and Audi Q7. Active all-wheel steering system is also widely used in heavy machinery and giant trucks to improve their flexibility in narrow road conditions.
According to foreign media reports, Ford's all-wheel steering patent will be activated and controlled by electronic control, which means that it is an active all-wheel steering system. The patent also mentions the use of Ackerman steering geometry to prevent the inner and outer tires from rotating around different centers when turning.
Active all-wheel steering system can greatly improve the maneuverability and flexibility of vehicles. If Ford applies this technology to Ford F-series pickup trucks, F-series trucks will become more popular.
