The course stability and the steerability of the two-section wheeled vehicle at high velocities during the lane change manoeuvreare studied in this paper. Mechanic-mathematical model is developed, on which base simulation programmes are elaborated. Simulation studies of the course stability at different velocities depend on some constructive and exploitation factors are made by these models. Based on the simulation results an idea for an algorithm and a semi-active control system of the resistance in the pulling-supporting device is proposed.

A three output microelectronic circuit functionally equivalent to a hydrogen bonding network is modeled. Proton transfer characteristics of each hydrogen bond of the network are emulated by block-elements in the microelectronic circuit with their respective l-V characteristics. These characteristics are coded in Matlab where the dynamic and static analyses are carried out. The results imply that in static mode the functionally analogous circuit operates as a current source or an amplifier. In dynamic mode the circuit behaves as a voltage driven triangular pulse signal source. The simulations show that the generated pulses at the three circuit outputs have different frequency, amplitude, and width.
