FIELD: engines and pumps. ^ SUBSTANCE: proposed method uses the value of at least one operating parametre selected to allow required braking moment. This method comprises determining required braking moment developed by the brake-decelerator and difference between required and developed braking moments. If said difference exceeds first tolerable value, brake-decelerator is controlled using the value of at least one second operating parametres. Second operating parametre is selected or adapted, or tuned to produce corrected developed braking torque. Developed braking moment is determined by actual or virtual braking moment transducer 3. First or second operating parametres are stored in memory in tabulated form. Operating parametres may be selected to the group of parametres including ICE exhaust system back pressure, supercharging pressure, pressure ahead or behind the turbine, turbine rpm or its variable geometry and position of vanes. In case difference between required and developed braking moment exceeds second tolerable value that exceeds first preset value, signal on fault is generated. Method of controlling is implemented by ICE brake-decelerator control system. Said control system comprises ICE control unit 12. Torque transducer 3 is mounted on ICE power transfer shaft 1a, 9, 10. ICE control unit 12 controls ICE operation and allows the control over brake-decelerator operation in compliance with selected control method. Said control unit 12 makes a part of transport facility control unit 14. ^ EFFECT: higher accuracy and reliability, optimum control. ^ 11 cl, 2 dwg |
