Problems solved by technology

[0004] However, due to the cross-section in the design of different application loads during unified control, the portability of this method is not good, and the original application load needs to be changed accordingly when other application loads are added, which makes the scalability of this method not good. Since each application load is not independently controlled, when some of the application loads fail, other application loads will also be affected, reducing system stability

Abstract

The invention discloses a vehicle control device and method, and a vehicle. The device comprises a primary master control module and at least one secondary sub-control module; the primary master control module is respectively connected with each secondary sub-control module, and each secondary sub-control module is externally connected with at least one application load; each secondary sub-controlmodule is used for determining a target application load according to received application feedback information of the corresponding external application load and feeding back the target load information of the target application load to the primary master control module; the primary master control module is used for formulating a power supply distribution rule according to the target load information and supplying power to the secondary sub-control modules according to the power supply distribution rule; and the secondary sub-control modules are also used for supplying power to the externalapplication loads according to the power supply distribution rule. According to the technical scheme of the embodiment of the invention, the modularization of vehicle application load control is improved, the processing flow of electric quantity distribution management is simplified, the independence among application loads is improved, and the stability of vehicle operation is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of power supply control, in particular to a vehicle control device, method and vehicle. Background technique [0002] With the development of automobile intelligence, networking and sharing, the application of automotive electronic technology is becoming more and more extensive, and new electronic and electrical technologies are changing with each passing day. A large number of application loads are often integrated under the same control device in the vehicle. Under the condition that the power supply of the application load remains unchanged, higher requirements are put forward for the distribution and management of the power of the control device. [0003] In the prior art, a centralized power management method is often adopted, and a unified power management module performs power management work on all application loads under the control device. For example, the state transition of...
