Kiepe Traction Control KTC
The Kiepe Traction Control KTC software was developed to optimize the drive control in electric trolleybuses and offers the following advantages:
- Fast torque control in every operating situation.
- Active damping of drivetrain oscillations even during passing a line-insulator with high traction torque effort (international patent).
- Gentle driving characteristics due to highly dynamic damping of torsional drivetrain oscillations.
- Reduction of wear on mechanical drive train components by active damping of mechanical oscillations.
- Optimized wheel slide and slip protection.
- Improved efficiency by using synchronous pulse patterns in the upper speed range. This increases the overall efficiency of the traction machine and traction converter.
- Reduction of noise and energy consumption with optimized machine flux control.
- Reduction of acoustic resonances in drivetrain and in braking resistor by optimized switching frequency modulation.
- Optimized driving characteristics in condition of icy overhead line.
- Reliable and stable start on very high inclines (tested on slopes up to 23 %)
- Highest priority on electrical braking capability, even in case of the overhead line voltage failure.
- High recuperation level and protection against consumption of the external energy.
- Controlled acceleration and deceleration at different loads and road profiles.
