Tesla Cybertruck Teardown Continues With A Look At Its Steer-By-Wire System

Even though Infiniti was the first manufacturer to bring steer-by-wire to a production car almost 10 years ago, that system was optional, and you could still opt for a conventional setup with a mechanical link between the helm and the wheels. It’s also offered as an option in the Toyota bZ4X and Lexus RZ450e.

The first true steer-by-wire production vehicle is the Tesla Cybertruck, and driving one takes a bit of getting used to since you have to apply a lot less lock than in a traditional setup, and it also has a variable ratio. This means it’s not very sensitive off-center, but the more you turn the wheel, the lock you apply increases progressively. This ratio also varies depending on the driving speed.

The Tesla Cybertruck is steer-by-wire only

Unlike other manufacturers that have offered steer-by-wire as an option in their vehicles, for the Tesla Cybertruck it’s the only available setup and it makes for an unusual driving experience that takes a bit of getting used to. 

One of the most unusual characteristics of the Cybertruck with its steer-by-wire system is that you can turn the steering wheel when the vehicle is powered off, and none of the wheels will turn. Do the same after powering on the Cybertruck, and you will see both its front- and rear-wheel steering racks working.

Steer-by-wire is definitely still a novelty in cars, although several manufacturers have announced plans to introduce it in production cars in the next few years—Mercedes is rumored to give its next S-Class steer-by-wire. If you’ve ever wondered how a system like this works, this video by Sandy Munro of Munro Live—the latest part of his Tesla Cybertruck teardown series—should shed some light. Sandy and his team first demonstrated how it works, then they extracted the front and rear subframes from the truck to get a better look at how they work.

They also show the steering column, which looks very different from any steering column you may have seen before. It stops where you would expect it to continue with a shaft that links to the steering rack, and it just has electronics, servos and wires that enable it to have a variable ratio. The steering rack (which interestingly appears to be supplied by ZF) has two motors for redundancy, so if one malfunctions, the backup motor can take over and keep the steering system alive.

The‌ Tesla Cybertruck has been making headlines⁣ since its initial ⁣unveiling, with its unique design and impressive performance capabilities.⁤ As the first teardown of⁤ the vehicle continues,⁤ more details are being revealed about the inner workings of this⁢ highly anticipated⁣ electric truck. One of ⁤the key components that has been examined ⁣is the Cybertruck’s steer-by-wire system, which represents a significant technological advancement in the automotive ​industry.

Steer-by-wire technology is a cutting-edge system that eliminates the need for ⁣a mechanical connection between the steering wheel and the wheels of the vehicle. Instead, the steering input from the driver is transmitted electronically to actuators that control the direction of the wheels. This system offers several advantages over traditional steering systems, including improved responsiveness, precision, and flexibility.

One of the main benefits of steer-by-wire technology is​ its potential for enhanced safety. By removing the physical connection between the steering wheel and the wheels, the system ⁢can help to prevent accidents caused by mechanical failures or ‌malfunctions. In addition, the system can be‍ programmed to provide assistance to the driver in emergency situations, such ‍as lane-keeping assistance or collision avoidance.

Another advantage of the ⁣Cybertruck’s steer-by-wire system is its ⁤potential for improved handling and performance. Because the system is fully electronic, it can‍ be fine-tuned to provide optimal steering feel and response,⁢ giving⁤ drivers greater control over their⁢ vehicle. Additionally, the system can be integrated with other advanced ⁣driver assistance systems,​ such as adaptive cruise control and autonomous driving capabilities, further enhancing the‌ overall driving experience.

Despite the numerous advantages of⁤ steer-by-wire technology, there are also some potential challenges and concerns⁢ that need to⁤ be addressed. One of⁣ the main challenges is ensuring the reliability and durability of the electronic components that make up the⁢ system. As with any electronic system, there is a risk ‌of software glitches, sensor malfunctions, or other technical ​issues that could affect ⁤the ⁤performance of the ⁣system.

Overall, the Tesla Cybertruck’s steer-by-wire system represents a significant step forward in⁣ automotive⁤ technology, showcasing the company’s commitment to innovation and pushing the boundaries of ⁣what is possible in the electric vehicle market. As‍ the teardown ⁢of the Cybertruck⁤ continues, it⁢ will ​be interesting to see what other technological advancements and features are uncovered,‍ further solidifying ⁢Tesla’s position as a leader in the industry.
