Tesla points to better range and efficiency with compact power steering patent
Tesla’s electric cars are already among the most efficient vehicles on the market, and this is shown by the immense gap between the range and efficiency of the company’s vehicles compared to their competitors from veteran automakers. Part of the reason behind this is Tesla’s continued improvements in its vehicles, which are rolled out and adopted as soon as they are refined and ready.
One of these improvements appears to have been teased in a recently-published patent application. Simply titled “Steering System for a Vehicle,” the document describes a smart, novel way of designing a power steering system that is more compact and less power-hungry. In the patent’s background, Tesla remarked that conventional power steering systems, which are usually hydraulically operated, are mostly bulky and space-consuming.
This is due to power steering systems utilizing a number of components that include cylinders, pumps, hoses, and control valves, to name a few. Hydraulic power steering systems also have complex designs, which add cost to a vehicle. Lastly, conventional power steering systems generally require a large amount of power to function. With this in mind, Tesla argues that there is a need for a new power steering system that is simpler, smaller, and more power-efficient.
Tesla’s novel power steering design involves fewer parts than the conventional system used in most vehicles. The electric car maker describes the design in its patent in the description below.
“The steering system includes a drive motor having a motor shaft. The steering system also includes a first gear reduction stage for receiving a first rotational input from the motor shaft and providing a first rotational output. A first gear meshes with a second gear of the first gear reduction stage via a helical gear mesh. The steering system further includes a second gear reduction stage for receiving the first rotational output from the first gear reduction stage and providing a second rotational output.
“The second gear reduction stage may include at least one of a strain wave gearing, a worm drive, and a planetary gearing. In case the second reduction stage is a strain wave gearing, the second gear reduction stage includes an ovular coupler, a flexible coupling, an outer spline, and a plurality of bearing members disposed between the ovular coupler and the flexible coupling. The steering system includes an output shaft for receiving the second rotational output from the second gear reduction stage.”
Tesla notes that its smaller, power-saving steering system, apart from being more power-efficient and compact, also includes several failsafes, which could, in turn, increase a vehicle’s safety. The company’s patent mentions “sacrificial or failsafe components,” which are designed to safeguard a vehicle’s sensitive components during the event of a breakdown. Such a design will likely contribute to Tesla’s electric cars and their already-stellar safety ratings.
“In some embodiments, steering system 102 has been shown to provide a 10% improvement over a hydrolytic steering system. Additionally, steering system 102 is a compact unit that consumes lesser space as compared to other steering systems that are commercially available in markets. Further, steering system 102 does not require large amount of additional power for operation. FIG. 6 illustrates a failure mode of steering system 102 in which one or more bearing members 244 of steering system 102 fail. Bearing members 244 of steering system 102 are designed to withstand high loads so that they do not fail during normal vehicle operation. However, bearing members 244 may be designed to withstand only a predetermined threshold of load. As a result, bearing members 244 fail when they are loaded beyond the predetermined threshold.
“For example, a bearing member 258 may eventually fail along a shear plane 260 when loaded beyond the predetermined threshold. Alternatively, bearing members 244 may undergo a bending failure, or any other type of failure. In such a situation, one bearing member 244 is a sacrificial or failsafe components, thereby safeguarding other components of vehicle, for example, drive motor 204 or an engine, against breakdown or seizing. More particularly, the one bearing members 244 fails, ovular coupler 238 locks and rotates with flexible coupling 240. Thus, steering system 102 can still be operated to allow vehicle to be driven for a certain distance and parked at an appropriate location. Bearing member 244 fails according to a sheer mechanism or another failure mechanism. Further, failed bearing member 258 can be replaced and vehicle can be reinstated without incurring any additional losses.”
It remains to be seen if Tesla’s compact power steering system will be adopted for the company’s upcoming vehicles. That being said, such a system is a perfect match for EVs such as the Tesla Semi, the Tesla Pickup Truck, and the Model S and X Plaid Powertrain variants. These are all large vehicles, and their success in the market will likely be determined in no small part by their range and efficiency. In this light, every single innovation that could optimize these vehicles’ efficiency will most definitely be appreciated. After all, the less power is consumed by subsystems such as a vehicle’s power steering unit, the more power there is to turn an electric car’s wheels.

Tesla gamifies Supercharging with new ‘Charging Passport’
It will also include things like badges for special charging spots, among other metrics that will show all of the different places people have traveled to plug in for range.
Tesla is gamifying its Supercharging experience by offering a new “Charging Passport,” hoping to add a new layer to the ownership experience.
While it is not part of the Holiday Update, it is rolling out around the same time and offers a handful of cool new features.
Tesla’s Charging Passport will be available within the smartphone app and will give a yearly summary of your charging experience, helping encapsulate your travel for that year.

Tesla will include the following metrics within the new Charging Passport option within the Tesla app:
- Charging badges: Iconic charging badges for visiting places like the Tesla Diner, Oasis Supercharger, etc., Explorer Badge, and more
- Total Unique Superchargers Visited
- Total Charging Sessions
- Total Miles Added during Charging Sessions
- Top Charging Day
- Longest Trip
- Favorite Charging Locations
This will give people a unique way to see their travels throughout the year, and although it is not necessarily something that is needed or adds any genuine value, it is something that many owners will like to look back on. After all, things like Spotify Wrapped and Apple Music Replay have been a great way for people to see what music they listened to throughout the year.
This is essentially Tesla’s version of that.
With a handful of unique Superchargers already active, Tesla is also building some new ones, like a UFO-inspired location in New Mexico, near Roswell.

Tesla launches its coolest gift idea ever just a few weeks after it was announced
“Gift one month of Full Self-Driving (Supervised), which allows the vehicle to drive itself almost anywhere with minimal intervention.”
Tesla has launched its coolest gift idea ever, just a few weeks after it was announced.
Tesla is now giving owners the opportunity to gift Full Self-Driving for one month to friends or family through a new gifting program that was suggested to the company last month.
The program will enable people to send a fellow Tesla owner one month of the company’s semi-autonomous driving software, helping them to experience the Full Self-Driving suite and potentially help Tesla gain them as a subscriber of the program, or even an outright purchase.
Tesla is going to allow owners to purchase an FSD Subscription for another owner for different month options
You’ll be able to gift FSD to someone! https://t.co/V29dhf5URj

Tesla has officially launched the program on its Shop. Sending one month of Full Self-Driving costs $112:
“Gift one month of Full Self-Driving (Supervised), which allows the vehicle to drive itself almost anywhere with minimal intervention. All sales are final. Can only be purchased and redeemed in the U.S. This gift card is valued at $112.00 and is intended to cover the price of one month of FSD (Supervised), including up to 13% sales tax. It is not guaranteed to cover the full monthly price if pricing or tax rates change. This gift card can be stored in Tesla Wallet and redeemed toward FSD (Supervised) or any other Tesla product or service that accepts gift card payments.”
Tesla has done a great job of expanding Full Self-Driving access over the past few years, especially by offering things like the Subscription program, free trials through referrals, and now this gift card program.
Gifting Full Self-Driving is another iteration of Tesla’s “butts in seats” strategy, which is its belief that it can flip consumers to its vehicles and products by simply letting people experience them.
There is also a reason behind pushing Full Self-Driving so hard, and it has to do with CEO Elon Musk’s compensation package. One tranche requires Musk to achieve a certain number of active paid Full Self-Driving subscriptions.
More people who try the suite are likely to pay for it over the long term.

Tesla expands Robotaxi app access once again, this time on a global scale
Tesla said recently it plans to launch Robotaxi in Miami, Houston, Las Vegas, Phoenix, and Dallas.
Tesla has expanded Robotaxi app access once again, but this time, it’s on a much broader scale as the company is offering the opportunity for those outside of North America to download the app.
Tesla Robotaxi is the company’s early-stage ride-hailing platform that is active in Texas, California, and Arizona, with more expansion within the United States planned for the near future.
Tesla said recently it plans to launch Robotaxi in Miami, Houston, Las Vegas, Phoenix, and Dallas.
The platform has massive potential, and Tesla is leaning on it to be a major contributor to even more disruption in the passenger transportation industry. So far, it has driven over 550,000 miles in total, with the vast majority of this coming from the Bay Area and Austin.
First Look at Tesla’s Robotaxi App: features, design, and more
However, Tesla is focusing primarily on rapid expansion, but most of this is reliant on the company’s ability to gain regulatory permission to operate the platform in various regions. The expansion plans go well outside of the U.S., as the company expanded the ability to download the app to more regions this past weekend.
So far, these are the areas it is available to download in:
- Japan
- Thailand
- Hong Kong
- South Korea
- Australia
- Taiwan
- Macau
- New Zealand
- Mexico
- U.S.
- Canada
Right now, while Tesla is focusing primarily on expansion, it is also working on other goals that have to do with making it more widely available to customers who want to grab a ride from a driverless vehicle.
One of the biggest goals it has is to eliminate safety monitors from its vehicles, which it currently utilizes in Austin in the passenger’s seat and in the driver’s seat in the Bay Area.
A few weeks ago, Tesla started implementing a new in-cabin data-sharing system, which will help support teams assist riders without anyone in the front of the car.
Tesla takes a step towards removal of Robotaxi service’s safety drivers
As Robotaxi expands into more regions, Tesla stands to gain tremendously through the deployment of the Full Self-Driving suite for personal cars, as well as driverless Robotaxis for those who are just hailing rides.
Things have gone well for Tesla in the early stages of the Robotaxi program, but expansion will truly be the test of how things operate going forward. Navigating local traffic laws and gaining approval from a regulatory standpoint will be the biggest hurdle to jump.
