Surrey team to improve torque vectoring in EVs

摘要

Researchers at Surrey University have created a new method of torque vectoring aiming to improve electric vehicle (EV) safety and range.Developed as part of the EU's € 9.5m STEVE project to deliver new concepts in urban mobility, the Surrey team's method is suitable for implementation in everyday consumer EVs and aims to solve impracticalities in traditional torque vectoring approaches.Torque vectoring allows different amounts of drive power to be delivered to each wheel, improving the vehicle's power consumption, safety and control.Professor Aldo Sorniotti, head of the Centre for Automotive Engineering at Surrey University explained how multiple drive motors and torque vectoring techniques can allow for 'always-on' stability control systems, as opposed to a conventional stability system which only becomes activated when a vehicle is braking hard.
