Easy Driver - The Filo concept car,
developed by SKF and Bertone, shows how drive-by-wire
Latest application of the Time-Triggered Protocol is the TTCar model built by TTTech to demonstrate drive, steer, and brake-by-wire functions. Seven computer nodes calculate and control all car functions, exchanging data over the TTP network. Engineers developed the fault-tolerant system with TTP-Tools based on The MathWorks' MATLAB and Simulink without writing a single line of code. The toolset supports rapid prototyping and algorithm testing of vehicle dynamics models and control systems. Operators monitor and control the car via a laptop linked by wireless Ethernet. The demonstrator vehicle control each wheel separately.
Californiaís plan to mandate an electric vehicle market isnít the first such undertaking and certainly wonít be the last. But as the Golden State ratchets up for its next big step toward zero-emission vehicle status in 2018, it might be wise to consider a bit of history.
