Claims

[Claims for Utility Model Registration] A shift actuator that changes the gear position of a mechanical automatic transmission, a fuel adjustment actuator that adjusts the injection amount of an injection pump, a clutch actuator that connects and disconnects a clutch, and A selector lever sensor detects the shift operation position of a selector lever for performing a shift operation, an accelerator sensor detects the pedal stroke of the accelerator pedal, a latch position sensor of the injection pump, and a stroke of the clutch actuator. a clutch sensor, an engine rotation sensor, a gear position sensor of the transmission, a vehicle speed sensor, and a controller that controls the plurality of actuators to achieve appropriate operating conditions based on the outputs of each of the plurality of sensors. A shift control device for a mechanical automatic transmission, comprising: a brake sensor that detects the operating status of a brake pedal; and the vehicle speed sensor detects a vehicle speed lower than a predetermined vehicle speed while the accelerator sensor detects an idle stroke. and when the brake sensor detects release of the brake, the controller controls the clutch actuator and the shift actuator to shift the current shift gear position to a predetermined low speed gear position. A speed change control device for a mechanical automatic transmission.
