Problems solved by technology

[0005] The existing automotive power management system cannot manage the power supply hierarchically, and all electrical appliances are directly related, which increases the load and risk of the system. It is far from meeting the actual needs of users in the complex power consumption environment and various fault handling, and In the case of insufficient power supply, the driving demand cannot be met, which may cause the engine to stall due to the generator not supplying power during driving

Embodiment 1

[0044] This embodiment provides a power level management method, such as figure 1 As shown, steps S101, S102, S103 and S104 are included. Each step will be described in detail below.

[0045] Step S101: Obtain a power signal indicating the remaining power of the power supply through the power sensor.

[0046] After the power sensor obtains the power signal indicating the remaining power of the power supply on the car, it sends it to the power classification management module. Specifically, the power sensor can send the power signal to the power classification management module through the CAN bus of the controller area network. A power sensor can be installed on the car power supply, or the power sensor can be shared with the vehicle start-stop system. In this way, the power sensor is always on to obtain a stable power signal.

[0047] Before the power sensor is used, it is necessary to calibrate the power sensor through a test to ensure that the power signal of the power s...

Embodiment 2

[0060] Corresponding to Embodiment 1, this embodiment provides a power level management system, such as figure 2 As shown, it includes a power sensor 201, a power level management module 202 and a power distributor 203, which will be described in detail below.

[0061] The power sensor 201 is used to acquire a power signal indicating the remaining power of the power supply, and send the power signal to the power level management module 202 .

[0062] After the power sensor 201 obtains the power signal of the power supply on the car, it sends it to the power management module 202. Specifically, the power sensor 201 can send the power signal to the power management module 202 through the CAN bus. A power sensor 201 can be installed on the vehicle power supply, or the power sensor 201 can be shared with the vehicle start-stop system. In this way, the power sensor 201 is always on to obtain a power signal with a stable power supply.

[0063] Before the power sensor 201 is used,...

Abstract

The present invention provides a power supply hierarchical management method and system. The method includes: obtaining a power signal indicating the remaining power of the power supply through a power sensor; The power level is set, and the power signal is converted into a corresponding preset level on-off control signal, and the preset level on-off control signal includes an instruction to instruct some electric equipment to be powered on and other electric equipment to be powered off; The on-off control signal of the preset level is sent to the power distributor; the power distributor receives the on-off control signal of the preset level, and controls the on-off of the electrical equipment according to the on-off control signal of the preset level. The power supply hierarchical management method and system provided by the present invention can manage the power supply hierarchically, reduce the load and risk of the system, and meet the driving demand when the power supply is insufficient.

Description

technical field [0001] The invention relates to the technical field of vehicle design, in particular to a method and system for hierarchical management of power supplies. Background technique [0002] At present, driving safety, as an important attribute of automobiles, has received more and more attention. This phenomenon has promoted the rapid development of various automotive safety systems from the level of product demand. As an extremely important safety system, the automobile power management system plays a vital role in the normal driving of the automobile. [0003] At present, the vast majority of automotive power management systems are still only at the level of power distribution, distributing power to different electrical appliances, forming a "one size fits all" management model. [0004] In the process of realizing the present invention, the inventor has found that there are at least the following problems in the prior art: [0005] The existing automotive po...
