    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 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 heavy vehicle brake control method includes: activating two electro-pneumatic proportional valve control modules to perform braking along a front-axle electrical brake loop and a rear-axle electrical brake loop, respectively; while the two electro-pneumatic proportional valve control modules perform braking along the front-axle electrical brake loop and the rear-axle electrical brake loop, judging malfunctions by detecting the two electro-pneumatic proportional valve control modules; if none of the malfunctions is detected, the two electro-pneumatic proportional valve control modules continuing to perform braking along the front-axle electrical brake loop and the rear-axle electrical brake loop; and, if one or more malfunctions are detected, then switching on a brake-pedal cable control module to control the brake pedal of the brake valve to perform braking. In addition, a heavy vehicle brake control device is also provided.
