Lamborghini develops “next-generation” vehicle dynamic control
aerobd.news : The announcement of a new model of Lamborghini is always exciting, especially when it is a special model like the Huracán EVO, a next generation V10 super sports car based on the performance of the Huracán Performante. However, what makes the EVO extra special is that Lamborghini has stated the car will incorporate “next-generation” vehicle dynamic control technology. As Stefano Domenicali, CEO of Automobili Lamborghini stated, the Huracán EVO, “takes the extraordinary abilities of the Huracán Performante and combines state-of-the-art vehicle dynamic control to amplify the everyday Huracán driving experience. The Huracán EVO is the very definition of evolution: it is a step ahead, redefining the segment parameters.
It is remarkably easy to drive, while delivering the most responsive, sensory and agile driving experience, in every environment.” It all sounds impressive – as will the car’s 640hp, 5.2-liter naturally-aspirated V10 – but what is the technology that will make the EVO a worthy successor to the Performante? Key features include the Huracán EVO’s new rear-wheel steering system, as well as the torque vectoring system working on the four wheels. Even more important is the new Lamborghini Dinamica Veicolo Integrata (LDVI) system, a central processing unit that controls every aspect of the car’s dynamic behavior, integrating all of the car’s dynamic systems and set-up to anticipate the next move and needs of the driver, interpreting this into what Lamborghini says will be “perfect driving dynamics”.
The supercar maker has also developed an enhanced, more precise version of Lamborghini Piattaforma Inerziale (LPI), a comprehensive set of accelerators and gyroscope sensors placed at the car’s center of gravity. LPI monitors in real-time the vehicle’s dynamic attitude with regard to lateral, longitudinal and vertical accelerations, as well as roll, pitch and yaw rate. The magnetorheological suspension – also upgraded from the Performante spec – instantaneously adapts the damping following inputs from the LPI. The enhanced all-wheel drive and torque vectoring, combined with a new advanced traction control system, allows traction to be directed to a single wheel, as required. The enhancements don’t need there, as the Lamborghini Dynamic Steering (LDS) system has also been tweaked to provide higher responsiveness in corners while requiring the lowest steering angles. Coupled with the rear-wheel steering, agility at low speed is assured, as is stability in high-speed cornering and severe braking.
The combination of all these systems is governed by the LDVI, which can process data in real time, recognizing the driver’s intentions as transmitted to the car through the steering wheel, brake and accelerator pedal inputs, engaged gear – and of course the driving mode selected, whether the normal Strada mode, Sport or the hard-edged Corsa mode.
External conditions are determined through the active suspension and all-wheel drive grip estimation function. All of this information is analyzed and processed by the LDVI, which turns them into precise inputs for the vehicle dynamics systems. A ‘feed forward logic’ is implemented via the dynamic controller, which means the car doesn’t just react, but can intelligently try to ‘predicts’ the best driving set-up for the next moment.
