Nissan introduces e-4orce

New EV all-wheel control technology enhancing steering, braking and cornering performance to help improve driving confidence has been released by Nissan.

Pioneering the Nissan Leaf a decade ago, Nissan is introducing e-4orce to boost acceleration and torque – the “4” representing four-wheel control.

Now in final development stages, Nissan’s e-4orce balances powerful performance and control, enhancing driver confidence by tracing the intended driving line on a variety of surfaces, without the driver having to change driving style or input.

During the 2019 Tokyo Motor Show and at CES 2020 in Las, Nissan privately demonstrated e-4orce in a specially constructed test car using a Leaf e+ to allow drivers to experience the technology’s potential.

It’s an advanced system built around dual electric motors instead of the single motor Nissan has been using until now.

Nissan says an all-wheel-drive system is a logical next step, especially with the Ariya Concept strongly hinting at a future EV crossover.

The new tech reacts to driver input with ultra-precision control three times faster than the blink of an eye.

This not only provides the driver with instant, smooth acceleration but also ensures the control technology can handle a wide range of scenarios.

The e-4orce shines when the driver has to suddenly react to avoid something in the road, the system managing and conveying the driver’s intentions and expectations smoothly and efficiently.

Nissan’s engineers built on the know-how gained from the Nissan GT-R’s Attessa E-TS torque split system and the Nissan Patrol’s intelligent 4×4 system to maximise power output, braking and chassis control.

“This technology offers a new level of control,” Nissan’s powertrain and EV engineering division leader Ryozo Hiraku says.

The system constantly modulates the output of each onboard twin electric motor as well as each wheel brake control to create dependable control for the driver.

Typically when turning, a vehicle tends to veer outside of the corner during acceleration, causing the driver to either apply more steering input or reduce speed (understeer).

The e-4orce distributes torque to the vehicle’s front and rear wheels to maximise tyre grip according to road surface conditions and the vehicle’s situation.

Its all-wheel-drive balance defaults to a 50/50 distribution, but it can also transfer up to 100% of power to either the front or rear wheels, and a mix in between, for various road and driving conditions.

Deceleration force is optimally controlled at each of the four wheels, though a combination of regenerative braking and hydraulic braking, thereby improving turning performance in addition to deceleration.

The new system also delivers a smooth ride quality for all occupants under multiple driving scenarios, reducing vehicle pitch and dive which keeps occupant more level, helping prevent motion sickness such as in stop-and-go traffic.
