Will the Rear Wheels Turn When Steering a Car?

[MacPiper]

When steering a car, the rear wheels do not turn directly, but they can be indirectly controlled by the front wheels. Rear wheel steering systems are divided into: passive rear wheel steering and active rear wheel steering. Passive Rear Wheel Steering: Hard rubber blocks are installed at certain connection points between the rear suspension and the vehicle body. When the car turns, causing uneven compression on the left and right sides of the suspension, these rubber blocks deform under pressure, resulting in a change in the rear wheel alignment (toe angle), thereby achieving rear wheel steering. Active Rear Wheel Steering: The vehicle's computer collects data such as steering input and speed, then commands a servo mechanism to move the tie rods left or right. These tie rods are connected to the rear wheel linear structure, thus controlling the rear wheels to produce a certain steering angle.
