Smart Managing System ECO  Chip 3.0

With strong computing capacity of 32-bit dual-core VCU processor  and upgrading the control hardware and control strategy, ECO-Chip 3.0 system greatly improve the safety, stability, comfort and charging safety and achieve the function of  EAPM (Emergency Assist for Pedal Misapplication), HAC(Hill-start Assist Control), ASR( Anti-skidding control) and Crawl Control  etc.

ECO-Chip 3.0 system is easy to update by  OTA (Over the Air Technology).

EAPM preventing pedal misapplication

Intelligent identify of driving intention and intervene to avoid safety accidents caused by pedal misapplication

ASR drive anti-skidding control

Limit the tire slip ratio when accelerating, enhance the traction power for better running stability.

DSAC (downhill safety auxiliary control)

Dynamically adjust the electric braking force for cruise speed downhill, reduce driving fatigue and brake wear.

EPB electronic parking brake

One button to achieve temporary parking or long-time parking


Life-cycle Optimal Control(LOC)

Real-time prediction of power battery life

Optimization of energy distribution and drive control strategy

Ensure high-efficiency operation of the vehicle  with the power battery performance gradual decreases during the life cycle
Comprehensive Thermal Management(CMT)

Adopting King Long Patented technology of thermal management

Comprehensive control and Multi-objective arrangement for thermal management of power battery, motor, and high-voltage controller

Ensure all systems to operate within optimum temperature range.

Improve energy utilization efficiency,reduce power consumption with intelligent control algorithm( around 5% energy saving). 

SOH: Battery State of Health
SOC: Battery State of Charge

Dynamic Calibration of Electric Accessory Consumption(DCEAC)

Real-time dynamic calibration for energy consumption of  the electrical accessories

More accurate energy distribution

Ensure power output more aligned with driving intention

Further improve control reliability and energy comsumption (around 2% energy saving)




Intelligent Driving Guidance System

Driver Monitor System(DMS)

Real-time monitoring of driver's facial emotion, posture and driving behavior,

Timely warning and alert if abnormal detected and report to the cloud/remote system.

Intelligent Guidance Control  

Speed management in the crossing
