发明名称 Retarding system implementing transmission control
摘要 A retarding system for a work machine having a power source, a transmission, and a manually operated braking mechanism is disclosed. The retarding system has an engine retarder associated with the power source and a controller in communication with the transmission, the manually operated braking mechanism, and the engine retarder. The controller is configured to determine a deceleration rate of the work machine and compare the deceleration rate of the work machine to a predetermined threshold rate. The controller is also configured to determined if the manually operated braking mechanism is active and to cause the transmission to downshift if the deceleration rate is less than the predetermined threshold rate and the manually operated braking mechanism is determined to be active. The controller is further configured to prevent the transmission from downshifting if the deceleration rate is less than the predetermined threshold rate and the manually operated braking mechanism is determined to be inactive.
