Rivian patent hints at real-time brake wear monitoring system using driver profiles
Rivian’s attention to detail on its all-electric vehicles is laudable, and a recent patent application by the outdoor adventure company for monitoring brake wear continues that theme. In an application titled “Methods, Systems, and Media for Non-Contact Brake Pad Wear Determination”, a method of estimating the wear on individual breaks via computer algorithms is described. Once calculated, the information is then made available to drivers for planning purposes via the infotainment screen on the R1T pickup truck and R1S SUV. The application published on August 1, 2019 under US Patent Publication No. 2019/0234475.
The background of Rivian’s application stated the following reasons why the invention is needed:
“Current approaches for determining brake pad wear…tend to merely indicate when brake pads are fully worn, for example, using a brake pad indicator that causes the brakes to squeal when the indicator contacts the brake disc or that causes an indication on a dashboard of the vehicle to be presented. It may be useful for a driver to know a current wear condition of the brake pads before the brake pads are fully worn, for example, to plan for vehicle maintenance. However, it can be difficult to determine a current wear of the brake pads.”
While not an official reason listed on the patent, one could also assume brake squealing as an annoying sound in itself would also merit the invention’s usefulness as a reliable preventative.

Overall, Rivian’s application calculates the amount of wear on its vehicles’ brakes by comparing data points gathered from two braking events. The amount of pressure applied plus the distance traveled at two different intervals is collected, then compared to a brake database, and an estimate of the mileage left before a change is needed is provided to the driver. The calculation can also include the driver’s braking history to more accurately reflect the mileage. In other words, if you’re a bit rough on the brake pedal, Rivian’s software will take that into account and probably shorten the mileage you have left before needing replacement parts compared to someone that drives…differently. Here’s the formal language for this ability:
“In some embodiments, the method further comprises associating a braking profile with an operator of the vehicle, wherein the indication of the wear amount of the brake pad includes a number of miles until the brake pad requires replacement that is estimated based on the associated braking profile.”
The method described in the claims of the application that calculate the wear on the brakes indicates a process initiated by the driver, i.e., the driver initiates a brake wear test on the center touchscreen and uses the brakes at two intervals as instructed by the vehicle’s computer to determine the wear percentage. However, the description of the application indicates that the brake testing can also happen in real-time during normal operation. The formal language for this reads as follows:
“…In some embodiments, [the testing] process…can receive a group of brake caliper measurements and corresponding brake pedal travel distances…during application of the brake pedal during normal operation of the vehicle…Additionally, in some such embodiments, [the testing] process can present indications of brake pad wear at any suitable time, such as a next time the vehicle is turned on, and/or at any other suitable time.”
This application is yet the latest nod towards Rivian’s development of a comfortable and luxury driving experience for its vehicle owners. The car maker’s branding as an outdoor electric adventure company really seems to have embraced its mission to get people outside exploring more by making the experience as convenient as possible. Whether it’s ample storage capacity, swapping out cargo modules, extending battery range with a digital jerry can, a portable kitchen built specifically for the R1T pickup truck, or now, being able to easily plan ahead for basic vehicle maintenance by checking a screen, Rivian is continuing its march against barriers to enjoying nature anywhere.
There’s a new phrase that seems to be developing based off of an old one about willpower: “Where there’s a Rivian, there’s a way.”
The Tesla Semi is entering a new Pilot Program with Paper Transport, LLC (PTI), a Wisconsin-based transportation provider. The company will test the Semi’s Long Range configuration through “dedicated operations within the Chicago market.”
Chicago presents an interesting challenge for the Semi, as it will be a colder-weather climate that will test the Semi’s ability to operate in lower temperatures and in potentially large accumulations of snow. This is something Tesla has been testing with the Semi in Alaska and even in Northern California during the colder months, but Chicago will present a truly tough midwestern winter.

PTI says it is using the Semi to evaluate its strategy of reducing transportation emissions while maintaining performance, reliability, and cost efficiency. These are major arguments for the Semi being introduced into new fleets.
CEO of PTI Tyler Ellison said:
“PTI has been a leader in sustainable transportation solutions for over 15 years. We take a consultative approach to helping customers identify and implement the right transportation solution for their network. Our partnership with Tesla expands our portfolio alongside renewable natural gas and intermodal, giving customers more ways to reduce Scope 3 emissions without compromising service or economics.”
PTI is far from the first company to adopt the Semi within a fleet, as Tesla entered strategic agreements with PepsiCo. and its subsidiary Frito-Lay for a Pilot Program that extended throughout the California region.
Tesla has let companies like those utilize the Semi to determine whether it would be suitable for their operations. Additionally, Tesla gets valuable information regarding the Semi’s performance, knowing what to improve and what is ideal for companies that will utilize the all-electric truck for regional and nationwide logistics.
PTI plans to utilize the Long Range configuration, which is priced at $290,000 and features a range of approximately 500 miles, a three-motor powertrain, up to 800 kW of drive power, and consumption of just 1.7 kWh per mile.

VP of Maintenance at PTI, Bryan Ellen, added:
“We are excited to partner with Tesla, leveraging their ever-evolving technology. We are bullish in our estimation of the parallels available between our dedicated model and the efficiency of their fully electric Class 8 tractor. We anticipate a growing synergy between our businesses as we work to facilitate this sustainable solution for our customers.”
PTI has logged more than 87 million miles using sources like compressed and renewable gas, but now is looking to take it a step further with fully electric operations.
Tesla revealed on Monday that it is building a new autonomous vehicle at Gigafactory Texas, its plant just outside of the City of Austin. This particular vehicle will be geared toward those who are in need of a wheelchair-accessible car that would require no human driver for operation.
According to a new report from Wired, Tesla’s Senior Policy Advisor, India Herdman, told members of the Washington D.C. City Council on Monday:
“We are in development for a purpose-built, wheelchair-accessible autonomous vehicle. We know that paratransit can be very difficult, and people who are confined to wheelchairs permanently should still be able to move around freely, so that is an active product being built by Tesla in Texas.”
This builds upon what CEO Elon Musk said last year on X, which confirmed the company was working on accessible rides within its Robotaxi platform, which currently is confined to the Model Y.

Tesla is also developing the Cybercab, which started employee rides last week. However, this vehicle is not necessarily geared toward wheelchair accessibility.
That leaves a major gap in the autonomous ride-sharing program that Tesla is attempting to build; the company has been pretty clear that it does not want to complicate its manufacturing lines by bringing in a wide array of body styles.
However, it seems necessary to have something larger that could help transport people to appointments when they cannot drive. For wheelchair accessibility, the Robovan, which was unveiled at the “We, Robot” event in October 2024, seems to be the most ideal solution:
Herdman did not indicate whether she was referring to the Robovan or if Tesla is building yet another body style that is geared toward full autonomy but also caters to the handicapped.
Tesla might need to develop something specifically for the handicapped in order to align with the Americans with Disabilities Act, which prevents discrimination against people with disabilities in transportation services. Uber was hit with a lawsuit late last year for “refusing to reasonably modify its policies, practices, or procedures where necessary to avoid discriminating against riders with disabilities.”
Tesla would obviously like to avoid this.
It will be interesting to see what Tesla will do with this project, and whether it will introduce something new to the market or just continue with the Robovan.
Tesla weirdly confirmed that its steering wheel-less and pedal-less Cybercab vehicle is now in the process of giving employees rides, a huge milestone for the vehicle program.
But the entire thing was super strange. On Friday, Tesla released a video stating that there was “Cool news from Giga Texas” and that employees were now taking rides in Cybercabs that have no manual controls. The units seen on public roads are engineering vehicles that have manual controls inside, a necessity as Tesla moved through the testing phase.
However, Tesla removed the video and reposted it shortly after with a more vague title. It seems like the employee rides are still going, but the video was adjusted slightly. The initial upload showed employees doing things like watching movies and adjusting the climate, but these snippets were removed in the second upload.

Nevertheless, the announcement from Tesla is that the Cybercab is operating with employees inside who can control the vehicle’s audio, video, climate, and destination settings through their smartphone app.
Tesla has already been testing Cybercab engineering units, but last month, it was able to self-certify for SAE Level 4, which would enable unsupervised self-driving in Texas. The company is moving toward that, and the plans have always been to launch Cybercab rides this year.
The Cybercab is potentially looked at as the next generation of Tesla’s mobility leg. For the past 15 years, the company has been known as somewhat of an automaker, among many other things. However, these passenger vehicles that Tesla has manufactured are now moving into a new realm, as they will eventually drive themselves with no supervision thanks to the Full Self-Driving suite.
The Cybercab is just the next step of that: a true vehicle developed for the sole purpose of ride-hailing. It has no human controls, it has only two seats, and it will get passengers from Point A to Point B with no awkward driver, no need for manual inputs, and with no stress.
Tesla is moving forward with other developments related to the Cybercab project as well. However, the big announcement will come when Tesla finally announces that it is launching Cybercab rides to the general public, something that it plans to launch either late this year or early 2027.
