Problems solved by technology

[0004] In the process of implementing the present application, the inventor found that the above-mentioned technology has at least the following problems: when the engine of the new energy vehicle is turned off, that is, when the new energy vehicle is in the static working mode, on the one hand, the radio, indicator light and other on-board equipment on the car And the control system in the car may still need to run. On the other hand, when the user restarts the engine or the off-vehicle equipment, the control system also needs to be able to respond in time. Therefore, the static power supply is usually kept at a high level power supply, which brings a large static power consumption and wastes energy

Embodiment Construction

[0051] The following is attached Figure 1-4 The application is described in further detail.

[0052] The embodiment of the present application discloses a static power supply control method for a new energy vehicle, which can be applied to a control system of a new energy vehicle. The new energy vehicle is equipped with a main power supply for normal driving, and a static power supply for powering on-board equipment in the vehicle when the new energy vehicle is in a static working mode. Wherein, the vehicle-mounted device may be an instrument, a display screen, a controller, a radio, an indicator light, a lighting lamp, and the like on the vehicle. refer to figure 1 , the control system of the new energy vehicle includes a central controller and several equipment controllers. The central controller is used for overall control and monitoring of the main power supply, static power supply and equipment controllers. Car Equipment. The device controller includes two working st...

Abstract

The invention relates to a static power supply control method and system for a new energy vehicle, and belongs to the field of vehicle control, the method is based on a central controller in a control system of the new energy vehicle, a main power supply and a static power supply are arranged in the new energy vehicle, and the control system further comprises a plurality of equipment controllers. The equipment controllers are in one-to-one correspondence with the vehicle-mounted equipment, the working states of the equipment controllers comprise a running state and a standby state, and the method comprises the following steps: after it is recognized that the main power supply is turned off, controlling the static power supply to continuously supply power at a high level, so that the control system is in a normal working mode; detecting the working states of all equipment controllers according to a preset detection period; and when it is detected that all the equipment controllers are in the standby state, controlling the static power supply to supply power through square waves, so that the control system enters a sleep mode. The method and the system have the effects of reducing static power consumption and saving energy.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to a static power supply control method and system for a new energy vehicle. Background technique [0002] With the development of automotive electronic products, more and more automotive electronic products are used in automobiles, especially the new energy vehicles that have been promoted and used in recent years. In order to improve user experience, new energy vehicles are usually equipped with numerous on-board devices such as instruments, displays, controllers, and radios, and each on-board device usually corresponds to a dedicated device controller. [0003] Under normal circumstances, new energy vehicles are equipped with two sets of power supplies, that is, a main power supply for power supply during driving, and a static power supply for power supply in a static state. When the engine of the new energy vehicle is turned off, the power supply of the on-board equipment and ...
