A generalized model of thermofrictional contact was proposed which describes thermoelastic effects in the contact zone as well as a dependence of the friction coefficient on temperature and sliding velocity. Dissipative mechanisms responsible fordifferent modes of sliding instability were revealed. Domains of sliding instability were determined in the space of the parameters which define the system response to the dissipative, mechanical, and thermoelastic disturbances. It was shown that thethermoelastic deformations in the contact zone may produce stabilizing or destabilizing action on time history of sliding depending on the system parameters. Oscillation regime was found for sliding velocity, temperature and pressure in the contact zonewhich corresponds to the stable limit cycle on the phase plane of the system.
