A Deep Dive into Tesla Cybertruck’s Steering-by-Wire and Rear-Wheel Steering

Tesla has started delivery of its Cybertruck which has bold angular styling, a bulletproof body, and towing capacity of 11,000 pounds.

Cybertruck has many unique features like steer-by-wire, range-extender, rear-wheel steering, and 48V wiring architecture (harness).

The squarish-shaped steering of Cybertruck controls the direction of the front wheels using wired connected two motors (actuators). The steering signal is fed into a controller (computer) which decides the action of motors (actuators) to how much the wheels should be turned.

The steering system is provided with triple redundancy to provide better safety features in case two sensors generate an error the third level of the sensor can identify the correct input. 

Cybertruck features a wired steering system with a variable steering ratio, allowing the wheel to rotate up to 170 degrees. The sensors use ethernet communication for fast, smooth, and robust steering.

1. Steer by wire is more safe as compared to the conventional steering system. 2. More space in the cabin is available to use because there is no column (rod) connection to the axle.
