Research and development activities in the first years of the 21st century will be focused on achieving goals such as intelligent transportation systems (ITS) and intelligent vehicles systems (IVS). The main goal for ITS is to achieve greater road capacity and safety of travelling. Creating intelligent vehicle platoons, controlling vehicle position should prevent collisions at closer spacing and higher travelling speed. The goal of IVS is to equip vehicles with collision avoidance devices, instruments enabling the introduction of X-by-Wire (XBW) automotive control technology, devices enabling participation of automotive vehicles made by different manufacturers in controlled platoons - this requires standardisation of automotive vehicles electronic control units (ECU). The improvement of comfort and safety in IVS includes: GPS systems, high-intensity lighting, cruise control, electronically controlled seats, windows and mirrors, air conditioning, control of poweertrain, immobilization, entral locking and alarm system, computer trip planning and antilock braking. For the family of XBW systems such as throttle by wire (TBW) it is very useful to combine facility of control system prototyping using fuzzy logic (FL) with the possibility of neural network (NN) training through learning on the basis of input data sets. In such a case neuro-fuzzy (NF) controllers-throttle controller and brake controller - are used for the cruise control system. Invehicle networks are based on two main standards: protocol J1850 in the USA and protocol CAN in Europe. Both standards make it possible to reduce harness wiring and are predisposed for the introduction of XBW technology. Protocol J1850 uses pulse-width modulation (PWM). Protocol CAN is a real-time (RT) control bus designed for multiple nodes with different levels of priorities. For the future both protocols should be integrated into a common standard.
