Stellantis To Use Patented Vibration System To Simulate ICE Vehicles On EVs

Trying To Bridge The Gap Between ICE and EV Driving Experience...

Stellantis continues to bridge the gap between traditional internal combustion engine (ICE) powered vehicles and the next generation of electric vehicles (EVs). With gimmicks like Dodge’s Fratzonic Chambered Exhaust and eRupt multi-speed transmission, both of which are scheduled to debut in the upcoming Dodge Charger Daytona, they are trying to convince the public that EVs can be just as thrilling as their ICE counterparts. However, a patent filed last year by Stellantis suggests that the automaker is looking to go above and beyond to have EVs simulate ICE vehicles.

A patent filed with the World Intellectual Property Organization (WIPO) reveals a new Active Sound Enhancement (ASE) system that aims to blur the lines between EVs and traditional ICE vehicles, providing drivers with an immersive driving experience unlike any other.

The ASE system is at the forefront of Stellantis’ mission to make EVs more appealing and accessible to a broader audience. It addresses a common concern with EVs: their near-silent operation, which can pose safety challenges for pedestrians. To overcome this, Stellantis engineers have developed a system that not only replicates the authentic engine sounds of ICE vehicles but also simulates the tactile sensations of driving one.

At its core, the ASE system utilizes a sophisticated setup that combines sensor technology with advanced signal processing. Sensors strategically placed throughout the vehicle monitor various parameters such as motor speed, acceleration, wheel speed, and torque. This real-time data is then fed to a central controller, which orchestrates the generation of engine sounds tailored to the driving conditions.

However, Stellantis goes beyond just recreating sound. They recognize that the driving experience is multi-sensory, which is why they’ve integrated the Active Vibration Enhancement (AVE) system alongside ASE. AVE complements ASE by generating vibrations within the vehicle’s structure that mimic those produced by an ICE engine. These vibrations, transmitted through the vehicle body to the occupants, create a sensation akin to driving a traditional sports/muscle car.

The AVE system employs a force generator coupled to the vehicle’s body or chassis, capable of focusing vibrations to specific points within the vehicle such as the steering wheel and driver’s seat. This level of customization ensures a seamless and immersive driving experience, particularly for enthusiasts accustomed to the visceral sensations of ICE vehicles.

Moreover, Stellantis acknowledges that traditional “muscle cars” or “high-performance” vehicles may no longer have their characteristic exhaust sounds in an electric future. Additionally, current sound simulation systems may feel unnatural due to the lack of tactile feedback experienced with ICE engines.

By incorporating ASE and AVE systems into their EVs, Stellantis aims to offer consumers the best of both worlds: the environmental benefits of electric propulsion combined with the thrilling driving experience of a traditional sports car. Furthermore, these technologies could potentially improve safety by alerting pedestrians and cyclists to the presence of EVs in low-speed environments.

So, can Stellantis deliver a parallel driving experience to a traditional ICE vehicle? It remains to be seen.

But what do you think about all of these new gimmicks to blur the lines between EV and traditional ICE vehicles? Is it enough to sway you to transition to an EV? Leave your comments below.

at least they are trying to give an artificial authentic driving experience.

This is nothing new. I remember the rides in front of the grocery stores. Darn, I should have patented putting a playing card on the spokes of my bicycle.

there is prior art on that one.

While some of this may be new to the auto industry in this aspect, haptic feedback is a technology that has been around for quite some time. from Video game controllers to cell phones, we've been using this tech for so long, half of us don't even think about it anymore. I give Dodge alot of credit for putting the amount of time and energy into trying to make something that will appeal to their customers as they shift from living in the past to moving into the present and future with their new offerings. While everyone else is just making their EVs efficient, the Mopar brand is doing what it can to at least inject an amount of excitement and stimulation into something that would otherwise be just as boring and mundane as the rest of the EV world. The same goes for the fact that they're doing what they can to offer ICE performance even if it's not with the V8 engine. The Hurricane-6 is a beast of a three-liter engine with it's standard output variant putting out nearly the same horsepower as a 6.1L "Hemi" V8 with way more torque. This engine is capable of producing over 1000hp in whatever the CAT-X version may be and seeing that it will have forged internals, this powertrain can do way more than the factory 5.7L 6.1L or 6.4L can do and can potentially handle more power than a forged 6.2L with less than half the size. That's honestly impressive. We know already that Stellantis has the STLA: Large platform and STLA: Frame platform. Both of which will really cater to these new powertrains and alot of this new technology in ways that are alot more dynamic than what we currently have with the L-platform muscle cars, the current Durango platform and the Ram 1500 platform so it's pretty clear that performance is still on the agenda for the brand. I also look at the potential that the 3.0L has as a hybrid. Seeing that the new hybrid 4th-gen ZF 8-speed is a power adder in itself, what happens when you take a 550hp twin turbo inline-6 and connect it to a hybrid transmission that's able to make its own horsepower and torque? Not only that let's take it a few steps further. If Dodge is planning stage kits for it's EVs, why can't a Direct Connection Stage kit not only come with hardware to upgrade the power output of the turbocharged engine but also tuning algorithms to increase the EV output of the hybrid transmission? On the EV side of things, who's to say that Borla won't offer their own sound upgrade "Fratzonic" system with Acoustically Tuned Applied Kinetics (A.T.A.K) technology or Polyphonic Technology with no drone technology offering deeper, louder systems than what is on the car from the factory. Honestly, there is way more performance potential with what is coming that what we currently have. I think we may be pleasantly surprised with what is coming from the Brand in the next few years.

Knowing it has forged internals and comes from the factory with 26psi of boost tells you you can increase boost safely at least %20 more, and the 1000hp on the road version is not that hard to get compared to the Hellcat engines.

... If Dodge is planning stage kits for it's EVs, why can't a Direct Connection Stage kit not only come with hardware to upgrade the power output of the turbocharged engine but also tuning algorithms to increase the EV output of the hybrid transmission? ...

I wouldn't bet money on DC for the ICE engines.. They took a long time to certify their kits for the 6.2 engines, and that's only up to stage 2, and stage 3, from what it seems, is dead in the water.
