FYI: Stellantis patents a new hybrid-specific launch control system designed to optimize both electric and combustion power while reducing stress on motors.
### Stellantis’ New Hybrid-Specific Launch Control May Revolutionize Performance Hybrids
Future Stellantis performance hybrids could soon feature an innovative launch control system, as indicated by a recently discovered patent filing.
### New Hybrid-Specific Launch Control Patent
Stellantis submitted a patent application in February 2024, which was subsequently published by the United States Patent and Trademark Office (USPTO) on Aug. 8, 2024. The patent outlines a cutting-edge launch control mechanism tailored for hybrids, aiming to enhance acceleration performance.
### Enhancing Launch Control for Hybrids
Current launch control systems generally involve the driver simultaneously pressing the brake and accelerator pedals before releasing the brake to launch. However, according to Stellantis, this method doesn’t translate well to hybrid powertrains. Traditional systems prioritize the transmission control unit, which can strain electric motors and cause uneven starts.
To combat this, Stellantis proposes an alternative approach. Their method allows the hybrid system’s controller to take the lead, ensuring that the internal combustion engine (ICE) and the electric motor work in harmony. This system introduces a “preparation phase” to reduce electric motor torque before ramping up the engine revs. Following this, a “launch phase” will gradually integrate the electric motor’s torque with that of the ICE.
### Potential Layout and Components
While the patent does not specify the exact type of internal combustion engine, it does mention critical components such as a dual-clutch transmission, a propulsion electric motor, and a secondary belt-driven starter/generator motor. This indicates the possibility of this launch control system being employed in future Stellantis hybrid models.
### Ideal Fit for Dodge
Among Stellantis’ portfolio of brands, Dodge stands out as a prime candidate for incorporating launch control in its hybrid models. Known for its muscle cars and high-performance image, Dodge’s dedication to speed and acceleration perfectly aligns with this new technology. The 2024 Dodge Charger Daytona, set to debut later this year in an all-electric variant, will be followed by a twin-turbo inline-6 in 2025. This progression suggests that a hybrid variant equipped with launch control could also be on the horizon.
### Conclusion
Stellantis’ proposed hybrid-specific launch control system marks a significant step forward in optimizing hybrid powertrains for performance driving. By balancing the roles of the electric motor and ICE, it promises smoother and more efficient launches, potentially setting a new standard in the industry.
