e-4ORCE is an electric-drive four-wheel-control system that freely controls driving force via integrated control of the two front and rear high-output motors and brakes.
From everyday driving to winding and slippery roads, this unprecedented system improves all types of driving, providing powerful, high-quality, and responsive driving.
The system detects the slight slippages of each wheel and quickly distributes the driving force if slippage occurs.
e-4ORCE detects slight tire slippages and determines grip limits while driving. By calculating driving force that realizes turning, acceleration, and deceleration according to the driver's operation and then controlling the front and rear motors and the left and right brakes in an integrated manner, the system controls driving force to maximize the grip of the four wheels.
Compared to conventional mechanical 4WD that can only vary the distribution of driving force up to 50:50 due to their structure, a 4WD system with motors on each of the front and rear wheels has the potential to freely change the driving force from 100:0 to 0:100. By combining this with braking control, the driving force on the left and right can be changed, and the driving force on all four wheels can be controlled at high speed and with high precision.
- e-4ORCE is installed in electric vehicles such as the Nissan Ariya and the X-Trail e-POWER.
