Design and implementation of automatic transmission electronic control system for mining trucks

Based on the algorithm and control strategies of automatic transmission in the Truck, electronic control unit (ECU) are designed. Furthermore, a design model is applied to optimize shift quality and also to reduce test time. The circuit diagram of electronic control unit (ECU) hardware composes of power supply module, signal input channels, signal output channels, data storage module, driver circuits, and communication interface module. They are designed and then ECU hardware is manufactured. Installed in TEREX TR100 mining truck, the test results of ECU system is satisfied and worked stably and reliably.
