KIEPE e-control system

For the individual control of heavy electric commercial vehicles (buses, trucks, special vehicles), KIEPE engineers rely on the latest generation of intelligent control units (ECU/TCU).

• The energy control unit (ECU) ensures optimized energy efficiency, regulates the charging processes and controls all auxiliary units up to the air conditioning system or air compressor.
• The traction control unit (TCU) is part of the drive system and controls the electric motors and all traction processes from braking to acceleration.

The KIEPE basic software is already programmed to ASIL level as standard. In addition, the legal requirements of cybersecurity are met.

Depending on the customer's requirements, the application software is developed by the engineering team according to the V model and offers countless control options - see the list below.

More than 30 years of experience in the system integration of electrical systems and components in e-buses are incorporated here.

The following list describes the properties of the traction control unit.

• Processing operating mode
• Processing direction selection
• Setpoint processing in the driving and braking program (torque)
  • Creeping
  • Anti-slip control
  • Torque limitation (temperature, articulation, ....)
  • One-pedal drive
  • Retarder lever
• Activation of emergency operation (drive)
• Traction locking during charging
• Interface to the HMI
• Warning and fault evaluation
• Fault memory
• Operating data acquisition
• Diagnostic interface
