Drive system with in-wheel motors which enables light-weight body structure, high energy efficiency and low road noise
For 2WD four wheel vehicles, 4WD four wheel vehicles, and 8WD eight wheel vehicles.
Can be used in both "ground up" models (newly designed electric cars) or existing cars.
The car is comprised of a platform installed with a drive system consisting of an in-wheel motor, inverter, and battery.
Cars installed with components certified by SIM-Drive will be labeled "by SIM-Drive" or "Platform by SIM-Drive".
This is technology for inserting motors inside the vehicle wheels.
The technology has been made feasible by developing a compact, high-efficiency motor.
The main advantages are the high energy efficiency, large usable space in the vehicle body, and highly simple vehicle structure.
While there have been concerns that this design, with the large weight under the suspension springs, would result in poorer riding comfort, demonstration tests have shown this not to be the case.
Four-wheel independent control makes full use of characteristic that each wheel has independent motor and is a control system which can adjust each wheel’s torque independently according to vehicle attitude, load distribution, acceleration rate.
Stable high-speed running and turning performance
Vehicle attitude stabilization
Ride quality improvement
Improvement of efficiency, elongation of range per charge
Brake mechanism simplification
