发明名称 Rollback prevention system for mobile machine
摘要 A rollback prevention system is disclosed for use with a mobile machine having an engine and a transmission. The rollback prevention system may have an input device configured to receive an input indicative of a desired travel direction of the mobile machine, a sensor configured to generate a signal indicative of an actual travel direction of the mobile machine, and a controller in communication with the input device, the sensor, the engine, and the transmission. The controller may be configured to make a determination that the actual travel direction of the mobile machine is opposite the desired travel direction based on the signal, and determine a load on the transmission. The controller may also be configured to selectively increase a torque output of the transmission based on the determination only when the load on the transmission is less than a threshold value.

主权项 1. A rollback prevention system for a mobile machine having an engine and a transmission, the rollback prevention system comprising: an input device configured to receive an input indicative of a desired travel direction of the mobile machine; a sensor configured to generate a signal indicative of an actual travel direction of the mobile machine; and a controller in communication with the input device, the sensor, the engine, and the transmission, the controller being configured to: make a determination that the actual travel direction of the mobile machine is opposite the desired travel direction based on the input and the signal;determine a load on the transmission based on a sensed pressure;monitor manual braking input from an operator of the mobile machine; andselectively control a torque output of the transmission based on the determination and based on whether a manual braking input from the operator is detected, and control the torque output of the transmission after an operator manual braking input is no longer detected to a same level of torque output as existed before the operator manual braking input was detected.
