Abstract

The invention provides a voltage holding device for an unmanned vehicle and the unmanned vehicle, and can be applied to the technical field of unmanned driving. The device comprises a first field effect transistor comprising a first source electrode, a first drain electrode and a first grid electrode, the first source electrode is configured to be connected with a positive electrode of a power supply of the unmanned vehicle, the first drain electrode is configured to be connected with an energy storage module, and the first grid electrode is configured to be connected with a control module; the control module is configured to be connected with the first field effect transistor in parallel, and the control module is configured to control the first field effect transistor to be in a conduction state or a cut-off state; the energy storage module is configured to be connected with a load of the unmanned vehicle in parallel, and the energy storage module is configured to store electric energy from a power supply; under the condition that the voltage of the power supply drops suddenly, the control module is configured to control the first field-effect tube to be in a cut-off state in response to the fact that the voltage of the first source electrode and the voltage of the first drain electrode meet a first voltage threshold condition, and the energy storage module is configured to supply power to the load in response to the fact that the first field-effect tube is in the cut-off state.

Description

technical field [0001] The present disclosure relates to the technical field of unmanned vehicles, and more particularly, to a voltage maintaining device for unmanned vehicles and unmanned vehicles. Background technique [0002] With the rapid development of unmanned technology, unmanned vehicles are increasingly used in many fields such as industrial and agricultural production, construction, logistics and daily life. As the application environment and the functions that need to be implemented become more and more complex, the unmanned vehicle needs to load more and more loads, and the power consumption of the load also increases. [0003] In the process of realizing the concept of the present disclosure, the inventor found that there are at least the following problems in the related art: the sudden drop of the power supply voltage of the unmanned vehicle will affect the normal operation of the load, thereby affecting the operation safety of the unmanned vehicle.
