Title:
VOLTAGE HOLDING DEVICE FOR UNMANNED VEHICLE AND UNMANNED VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/231318
Kind Code:
A1
Abstract:
The present 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, a first drain and a first gate, the first source being configured to be connected to a positive electrode of a power supply of the unmanned vehicle, the first drain being configured to be connected to an energy storage module, and the first gate being configured to be connected to a control module; the control module, configured to be connected to the first field effect transistor in parallel, the control module being configured to control the first field effect transistor to be in a turn-on state or a turn-off state; and the energy storage module, configured to be connected to a load of the unmanned vehicle in parallel, the energy storage module being configured to store electric energy from the power supply. Under the condition that a voltage of the power supply drops sharply, the control module is configured to control the first field effect transistor to be in the turn-off state in response to the fact that a voltage of the first source and a voltage of the first drain 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 transistor is in the turn-off state.
