Development Calculation and Simulation

For the SpeedE sporty full electric vehicle electric motors positioned near the rear wheels were combined with a steer-by-wire system, which allows high steering angles. To design the rear axle of the three seater optimally the ika at RWTH Aachen University uses the simulation software Aksis, which includes newly developed modules for elasto-kinematics calculation and suspension characteristic optimisation.

Research Vehicle Speede

The Institute for Automotive Engineering (ika) at RWTH Aachen University is currently designing SpeedE, a research platform as a sporty full electric vehicle. The concept combines two electric motors positioned near the rear wheels, an innovative steer-by-wire system controlled by sidesticks and a newly designed front axle allowing exceptionally high steering angles. Together this setup creates a highly manoeuvrable and agile three seater.

During the suspension design process the simulation software Aksis is used among others. Besides the existing...
