Energy saving control method for vehicular system

Abstract

The invention provides an energy saving control method for a vehicular system. A single-chip microcomputer and an analog switch are added to the vehicular system. A main chip and a communication module are connected with a power module through the single-chip microcomputer. The single-chip microcomputer is communicated with the main chip through a bus. The analog switch is connected to the bus for the main chip and the communication module and is also connected with the single-chip microcomputer through the bus. When a vehicle runs, the communication module, an external GPS device and other peripherals are all controlled to operate through the main chip; when a vehicle stops, the single-chip microcomputer controls the communication module to operate while the main chip, the external GPD device and other peripherals are turned off. The method has the advantages that operating status of corresponding high-power equipment can be controlled according to the status of a vehicle so as to achieve an energy saving scheme, and the service lives of certain devices can be prolonged.

Description

technical field [0001] The invention relates to an energy-saving control method for vehicle-mounted high-power equipment. Background technique [0002] As a separate system platform (such as a platform based on the arm main chip), the vehicle-mounted device needs to consume the power of the vehicle. With the increase in the functional requirements of the vehicle-mounted device, the type and quantity of the hardware (such as external GPS, communication module) configured by the vehicle-mounted device And the continuous improvement of performance also brings greater energy consumption. The traditional vehicle-mounted platform is based on a main chip (such as an arm chip) plus various external devices. The work of the vehicle-mounted devices is controlled by the main chip during work. According to different scenarios of the vehicle, some external devices do not need If used, it can be turned off to save energy. In extreme cases, only a few of the peripherals are required to wo...

[0004] In the parking state, since the vehicle is not started, the position remains unchanged. At this time, the external GPS device of the vehicle system can be turned off. The setting can be turned off. At this time, only the main chip and the external communication module are actually working in the entire vehicle system, that is, figure 2 The state shown, but in fact there is no corresponding energy-saving control method at present. In the parking state, in order to ensure the normal operation of the communication module, it is necessary to keep the main chip in the working state, resulting in a lot of waste
