ROME – A project by the University of Surrey in Great Britain has developed advanced methods that could significantly improve the performance of future electric vehicles. As part of the Steve project of the European Union, the university has developed several innovative approaches to “torque-vectoring” in battery-powered vehicles. In electric vehicles with multiple motors, different amounts of drive power can be supplied to each wheel, which improves the energy consumption, safety and driveability of the vehicles.
The process of calculating and optimizing the amount of power needed while the vehicle is moving is decidedly complex and requires a detailed knowledge of the environmental conditions to which considerable resources must be added in terms of calculation to process the data in real time, often making the techniques scarce. practices for everyday vehicles.
However, researchers from the British university have managed to develop advanced methods to improve torque-vectoring that can also be used in large-scale electric vehicles. For example, to improve the safety of electric vehicles, the team has created a stability control system that anticipates the curvature of the road, allowing the car to brake proactively when approaching a curve at too high a speed.
The researchers’ torque-vectoring system combines a predictive control model with fuzzy logic to adaptively prioritize vehicle dynamics or energy efficiency based on driving conditions. In short, the search for new technologies for the Evs continues at full speed and this latest discovery is added to the various studies carried out by researchers from the British university who had already developed a highly energy efficient torque-vectoring algorithm for an electric vehicle. with in-wheel motors.
