Temperature rise control for disc type friction torque transmitters |
摘要 |
A multi-speed transmission control has a CPU which utilizes a pre-programmed computer to control the interchange of the friction devices in the transmission. A routine within the CPU is executed by the computer at least when an impending ratio interchange is sensed. The routine uses stored data which includes friction disc parameters, engine operating parameters and vehicle performance parameters to determine if the impending shift will result in sufficient excess heat energy to cause the temperature of components in the friction device to exceed a predetermined design limit. If the temperature design limit will be exceeded, a reduced energy ratio interchange is commanded utilizing adaptive parameters for the upcoming shift; and if the temperature design limit will not be exceeded, the ratio interchange proceeds without adaptive parameters.
