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.”

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.

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 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

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 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 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.

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.

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.
