Product Overview

Developed by Horstman, the power regeneration system of the active suspension reduces the vehicle electrical power requirements. Key elements are:

  • An electromechanical actuator at each wheel, driven bi-directionally by a servomotor (PMSM), which can be used in both motor or generator mode.
  • A drive and power amplifier module that controls the commutation of the servomotor to produce the desired suspension force.
  • A storage element to temporarily store the actuator energy recovered when the motors are back driven, and to return the energy when the actuators need it. This device acts as a power filter to prevent overloading the power supply and to smooth out peak power demands.

Excess electrical energy is directed toward the vehicle battery system in full regenerative mode.

FeatureBenefit
Mild terrain regenerative modeActive suspension consume only few hundreds watts , no regeneration is produced
Good ride quality and mobility
Medium terrain  regenerative modeSome regeneration energy is stored and used during fast transient where high peak power is needed
Good Ride quality, good mobility and reduced vehicle body pitch and roll
Higher speed achieved compared to passive vehicle
Rough terrain regenerative modeActive suspension is acting as a generator, high peaks or power are produced in excess of system power demand
Energy stored in vehicle battery or in energy storage bank
Rolling resistance reduced, good ride quality and mobility
Energy absorbed by driver and crew significantly reduces
Electric vehicle compatibleImplementation vehicle with high voltage bus (300 VDC or 600 VDC) is simplified
System connects directly to High Voltage bus s connection to the high voltage bus with minimal interface
High voltage bus allows for faster system response and increase of efficiency
