Integrated Traction Control with Model-based Feed-forward Portion
- 37 Downloads
Bosch Engineering has adapted the concept of nonlinear model-based control, a proven approach to controlling lateral dynamics, to the control of traction. The applied algorithm consists of three main elements: an inverse model of the control travel, a feedback controller, and a set-point generator. Using road tests with a sports car, the performance of an integrated traction control system has been confirmed.
Traction Control Systems (TCS) debuted in series-production vehicles in 1987 , primarily to serve as an active safety feature. This safety aspect remains one of the key deliverables for the TCS; as such, it must always be factored in when writing new algorithms. However, for years now, automakers have been keen to save time and cut costs when calibrating controllers for vehicle dynamics. At the same time, the drive architecture has grown more complex with advancing electrification and hybridization. And customers and automakers are increasingly focusing...
