Title: METHOD FOR DETERMINING A LOAD SPECTRUM FOR A TRANSMISSION IN MOTOR VEHICLES
Abstract:
According to the invention, for determining the load spectrum of a transmission for motor vehicles, the transmission torque at the transmission input is calculated continuously from prescribed operating parameters. A matrix is generated from the continuously calculated transmission torque values, in which the frequency of occurrence of a transmission torque in a defined transmission torque class is entered and stored for each gear. The stored values in the matrix are preferably saved in a non-volatile memory for each shifting procedure during motor vehicle operation, and evaluated external to the vehicle for new development of transmissions.
