eMoSys 2.0

A modular drive and chassis system for electric vehicles

The aim of the eMoSys research project is to develop a highly adaptive and modular test vehicle. This vehicle will serve as a test vehicle to investigate various development and research topics, including in the field of driving dynamics, and to evaluate advanced control systems and new technologies.

The vehicle is based on a tubular frame, which forms the basis for the modularity of the vehicle. The removable front and rear modules allow the vehicle to be easily customised by exchanging components for different test requirements.

The vehicle design allows the customisation of various vehicle parameters such as wheelbase, track width, total weight, weight distribution and many more to simulate different vehicle types. In addition, the axle kinematics can be variably adjusted to set different driving characteristics. Together with a fully variable suspension system, this results in a large configuration range to set the vehicle dynamics according to the respective requirements.
The vehicle is equipped with extensive measurement technology that enables the vehicle data to be recorded and analysed in detail in real time and afterwards. This includes sensors for measuring vehicle dynamics parameters such as suspension travel, acceleration, yaw rate, speed, wheel slip and others.

The vehicle will serve as a test vehicle for investigating various development and research topics. In particular, this includes the development and optimisation of vehicle dynamics control systems in the area of over-actuated driving, which includes systems such as torque vectoring, brake-by-wire, steer-by-brake and all-wheel steering. Alternative HMI interfaces and ergonomic issues are also being researched. The next development goals are wheel-individualised electric drive, wheel-individualised steer-by-wire and wheel-individualised brake-by-wire.
