Embodiment Construction

[0026] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0027] The inventors found that when remotely upgrading the VCU of vehicles, especially electric vehicles, unmanned vehicles and other equipment, it is necessary to provide constant power supply to the devices that assist the VCU in remote upgrading when the vehicle is in standby. However, for equipment such as electric vehicles, providing constant power supply for these devices that assist VCU up...

Abstract

The invention is suitable for the technical field of vehicle battery control, and provides a power supply control circuit and method supporting vehicle VCU background remote upgrading and an unmanned vehicle. The power supply control circuit comprises a VCU unit, a VCU upgrading control unit, a constant power supply and a switch unit, the VCU unit is connected with the VCU upgrading control unit, the switch unit comprises a first switch circuit unit and a second switch circuit unit, the VCU upgrading control unit is connected with the constant power supply through the first switch circuit unit and the second switch circuit unit, the VCU unit is connected with the first switch circuit unit and can control the first switch circuit unit to be switched on periodically, and when the VCU upgrading control unit detects that the VCU unit needs to be upgraded, the VCU upgrading control unit can control the second switch circuit unit to be switched on. In addition, the power supply control circuit can be applied to the unmanned vehicle supporting automatic driving or / and unmanned driving, and the effect of reducing power consumption of the unmanned vehicle in a standby state is achieved.

Description

technical field [0001] The invention belongs to the technical field of vehicle battery control, and in particular relates to a power supply control circuit, a method and an unmanned vehicle that support the remote upgrade of the vehicle VCU background. Background technique [0002] VCU (full name in English: Vehicle Control Unit), translated in Chinese as: vehicle controller or vehicle control unit, as the central control unit of the vehicle, is the core of the entire control system. Specifically, the VCU controls the vehicle's power, steering, power management, etc., while monitoring the vehicle status, fault diagnosis, etc. Therefore, the power supply of the VCU is generally a constant power supply, that is, it is powered by the battery, while the power supply of other devices is mostly controlled by the VCU. That is to say, even if the vehicle is in the standby state, the VCU is still in the power-on state. [0003] When the vehicle is running, the VCU software will be ...
