EMS Calibration

Vehicle
Calibration

 

TENERGY provides vehicle calibration services which cover SULEV, EURO 5/6 and Tier 4 regulations and clients can choose total calibration services including emission, drivability and OBD-II or selective calibration one.

TENERGY has also very strong point in the fuel economy analysis of whole vehicle which evaluates individual effects of all fuel consumption elements quantitatively.

Our service work is increasing every year in cooperation with Korean car makers.

Principle of Energy
Flow-Down Method

To improve fuel economy of your car, understanding of engine + T/M + vehicle interaction and control strategy (ECU, TCU) are very Important

  • Needs for sub-system

  • Subsystem technology

  • Needs for component technology

  • Components

  • Component technology development and optimization

 
 

Benefits of Energy
Flow-Down Method

  • Energy Flow-Down Method can analyze the fuel consumption and contribution of each component and ECU/TCU control data through systematic approach.
  • Client can have the whole view for the quantitative fuel consumption and contribution of each component.
  • Client can recognize the weak and strong points against target vehicle.
  • Client can understand how top maker optimizes every component and control data to improve fuel economy.
  • Client can make catch-up plan of short, mid, long term in the most efficient cost.

How to improve fuel economy

 
 

Shift indicator principle

  • Fuel economy can be maximized in case that vehicle is driven in the area of engine highest efficiency.
  • Shifting point, optimized in terms of fuel economy is indicated to the driver.
  • Quick acceleration and deceleration are especially managed in consideration of passenger's safety.
  • The system that driving pattern can be managed by scoring system
 

  • Vehicle data
    (ECU)

  • Shift indicator
    (Data analysis)

  • Transfer to the driver
    (display, sound)

  • Shifting
