What Kind of Car Has Dual Steering Wheels?
2 Answers
Toyota Research Institute's newly released autonomous vehicle features two steering wheels. Introduction to Steering Wheels: A steering wheel is a round-shaped device used in cars, ships, airplanes, etc., to control the direction of movement. Its function is to convert the force applied by the driver on the edge of the steering wheel into torque, which is then transmitted to the steering shaft. Functions of Steering Wheels: Steering wheels are typically connected to the steering shaft via splines. Their primary function is to convert the driver's applied force on the wheel's edge into torque for the steering shaft. A larger-diameter steering wheel reduces the hand force required from the driver during steering. The steering intermediate shaft acts as a connector between the steering gear and the steering shaft, facilitating the standardization of steering gears, compensating for manufacturing and installation errors, and optimizing the installation of the steering gear and steering wheel in the vehicle.
I've seen many driving school cars equipped with dual steering wheels, such as modified Jettas or specialized training vehicles. The instructor can control the vehicle, and if the student makes a mistake while driving—like jerking the wheel or going too fast—the instructor can immediately take over the steering. This design is quite practical, reducing the nervousness of beginners on the road and avoiding potential dangers. I personally experienced this during my driving lessons, and it made me feel much safer. Modern driving schools also incorporate technology, such as sensors in dual-control systems that record operational errors, making it easier to replay and explain mistakes. Ultimately, dual-steering wheel cars are very common in the training industry, and they’re also found in other scenarios like special police vehicles, but the vast majority are used in driving schools.
