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: A motor control method for coupled an electronic vehicle is provided. The motor controller controls a motor and is powered by a battery. The motor control method includes: when a main relay of the motor controller suddenly breaks contact, in a first phase, feeding back a surge current into the battery to suppress the surge current by a diode and a first current limit resistor of a first protecting circuit of the motor controller; and, in a second phase, conducting a discharge switch of a second protecting circuit of the motor controller by a control unit of the motor controller, and releasing the surge current to a reference voltage range by the discharge switch and a second current limit resistor of the second protecting circuit.

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.
