Traction control
Dynamically distributes torque when any wheel is in skid management mode to obtain optimum tractive effort and stability.
Steering sensor
Optional addition to provide feed forward input to traction control system. Allows driver intent and wheel alignment to influence vehicle stability and tractive effort functions.
Vehicle attitude, yaw and gyroscopic sensors
Optional addition to provide further stability inputs to traction control system. Allows vehicle orientation and direction (if different from steering wheel implied direction) to be accounted for in determining optimum tractive effort distribution.
Differential/torque share functions
Standard feature incorporated within each wheel to allow optimum speed and torque share when cornering. Minimises tyre scrub and power wasted energy.
Efficiency optimisation
Dynamic management of power delivery to wheel ensures best use of available power. Accounts for motor related efficiency variations across speed and torque ranges.
Key safety items
Dual circuit power distribution
Dual circuit brake and accelerator systems ensure 100% redundancy
Hi-Pa™ drive ensures multi level redundancy in critical power systems
Dual wheel sensors
Dual CAN bus systems
Temperature monitors of all drive electronics, motor windings, battery cells and ultra capacitors. All temperature monitors fitted with fold-back control function.
Software and hardware over voltage and over currentmonitors
CAN watchdog
Processor watchdogs
