PCT No. PCT/FR96/01232 Sec. 371 Date Apr. 27, 1998 Sec. 102(e) Date Apr. 27, 1998 PCT Filed Aug. 2, 1996 PCT Pub. No. WO97/06374 PCT Pub. Date Feb. 20, 1997The method for eliminating an oscillation phenomenon in a motor vehicle with an automatic transmission system. The mass of the vehicle is determined on the basis of the measured speed, the current ratio of the transmission, the engine speed and the opening angle of the engine throttle. The acceleration of the vehicle and a higher ratio is predicted from the mass of the vehicle. The total amount of tractive resistance applied to the vehicle is determined. The probability that there will be an oscillation phenomenon at a higher ratio termed "oscillation risk" is determined from the acceleration and tractive resistance information. A signal for preventing shifting to the higher ratio is generated from the oscillation risk information, with the signal being adapted to be applied to a transmission control device. |
