AUBURN HILLS, Mich.,
Oct. 28, 2019 /PRNewswire/
-- BorgWarner has developed an innovative torque vectoring
system for electric vehicles which enables the use of just one
electric motor instead of the traditional two that are
typically found on electric vehicles. This solution is
cost-effective and features a compact design, significantly
reducing the vehicle space needed as well as the weight of the
system.
Leveraging its all-wheel drive (AWD) and coupling expertise and
portfolio, BorgWarner created its Torque-Vectoring Dual-Clutch
unit, which features two clutches – one inner and one outer – that
replace the conventional differential in an electric driveline.
Traditional torque-vectoring systems require two e-machines in the
rear, which are expensive and heavy, while BorgWarner's technology
conserves weight and space in the driveline, aiding in overall
vehicle efficiency.
"Our new Torque-Vectoring Dual-Clutch system, which minimizes
wasted torque, conserves energy and requires fewer components,
exemplifies how our existing internal combustion engine and
driveline expertise complements our work with electric vehicles,"
said Stefan Demmerle, President and
General Manager PowerDrive Systems, BorgWarner. "BorgWarner has the
extensive knowledge and expertise that customers need as the
industry evolves towards an electrified future."
Designed to improve electric vehicle handling and
maneuverability, BorgWarner's Torque-Vectoring Dual-Clutch commands
torque independently, distributing torque to the left and right
wheels from its position on the rear axle. The Torque-Vectoring
Dual-Clutch, connected to one electric motor and featuring two
reversible GenVI actuators (one per clutch), dynamically transfers
torque for improved steering response and controllability,
delivering a stable, fun-to-drive experience for the customer. This
system has a capacity of up to 2,600 Nm per clutch and has a
feature that disconnects the rear-axle when all-wheel drive isn't
needed. The vehicle then operates in front-wheel drive, resulting
in reduced losses and increased range for electric vehicles.
Start of production will kick off in the first half of 2022 for
a major, global OEM's electric vehicle.
