Abstract: A vehicle gearshift autonomous control device including a first actuator module, a second actuator module and an electronic control unit, is provided in an add-on manner to retrofit the vehicle transmission with both autonomous and human control gearshift functions. In an autonomous gearshift mode, the electronic control unit executes the vehicle gearshift autonomous control method and receives an autonomous gearshift command to drive the first actuator module to push a shift lever to implement a lateral shift selection, or to drive the second actuator module to spin a spin lever to implement a longitudinal gearshift. For vehicle security, whenever a vehicle gearshift autonomous control device failure or a human control gearshift intervention is detected in the autonomous gearshift mode, the electronic control unit shuts off the autonomous gearshift mode and switches to a human control gearshift mode to perform the human control gearshift function.

Abstract: For a manual gearshift control of conventional vehicle transmission, a vehicle gearshift automatic control device including a first actuator module, a second actuator module and an electronic control unit, is provided in an add-on manner to retrofit the vehicle transmission with both automatic and manual gearshift functions. In an automatic gearshift mode, the electronic control unit executes the vehicle gearshift automatic control method and receives an automatic gearshift command to drive the first actuator module to push a shift lever to implement a lateral shift selection, or to drive the second actuator module to spin a park lever to implement a longitudinal gearshift. For vehicle security, whenever a vehicle gearshift automatic control device failure or a manual gearshift intervention is detected in the automatic gearshift mode, the electronic control unit shuts off the automatic gearshift mode and switches to a manual gearshift mode to perform the manual gearshift function.

Abstract: A series-parallel coupling control method and system for a hybrid driver are suitable for a hybrid power vehicle. The hybrid driver is used to produce a driving force to drive a load. The hybrid driver includes a first power generation unit, a second power generation unit, and a main controller. The main controller selectively controls the system to drive the load in a series power coupling mode or a parallel power coupling mode. The main controller switches between the series coupling mode and the parallel coupling mode by using rotation speed compensation or torque/power compensation. Therefore, the driven load will not suffer from sudden thrust or jerk.
