CONTROL SYSTEM FOR SHIFTING A GEARBOX |
摘要 |
A power shift stage in the driveline of an internal combustion engine, is shifted depending on the load on the engine between at least two rotational speed ratios. A control system automatically controls shifting to improve driving comfort and increase productivity. The control system includes a switch connected to a fuel adjusting element or throttle, an engine rotational speed sensor and a control unit. The control unit automatically shifts the power shift stage in dependence upon the status of the switch and upon the sensed engine speed.
