Embodiment 1

[0041] The embodiment of the present invention provides a kind of automobile power supply management method, see figure 1 , the method includes:

[0042] Step 101: Monitor the turn-on signal and turn-off signal of the high-power load.

[0043] In this embodiment, the high-power load is a load whose power is greater than a predetermined power, such as a headlight, a wiper, a blower, a defrosting device, and the like. This step 101 is executed after the vehicle is started.

[0044] Step 102: Determine the number of currently turned on high-power loads according to the monitored on-signal and off-signal of the high-power loads.

[0045] Step 103: When the engine is in an idling state, adjust the rotational speed of the engine according to the number of currently turned on high-power loads.

[0046] It should be noted that idling refers to a working condition in which the engine is idling. When the engine is running, if the accelerator pedal is fully released, the engine is in...

Embodiment 2

[0051] The embodiment of the present invention provides a kind of automobile power supply management method, see figure 2 , the method includes:

[0052] Step 201: Monitor the turn-on signal and turn-off signal of the high-power load.

[0053] In this embodiment, the high-power load is a load whose power is greater than a predetermined power. This step 201 is executed after the vehicle is started.

[0054] Optionally, high power loads include headlights, wipers, blowers and defrosting equipment.

[0055] Step 202: Determine the number of high-power loads that are currently turned on according to the detected on-signal and off-signal of the high-power load.

[0056] Step 203: When the engine is in an idle state and the number of currently turned on high-power loads is equal to 1, adjust the engine speed to the sum of the initial speed and the first set value, where the initial speed is the rated speed of the engine when it is in an idle state .

[0057]Optionally, the ran...

Embodiment 3

[0068] An embodiment of the present invention provides an automobile power management device, see image 3 , the device consists of:

[0069] The monitoring module 301 is used to monitor the opening signal and closing signal of the high-power load, where the high-power load is a load with power greater than a predetermined power;

[0070] A determination module 302, configured to determine the number of currently opened high-power loads according to the monitored open signal and close signal of the high-power load;

[0071] The adjustment module 303 is configured to adjust the rotational speed of the engine according to the number of currently turned on high-power loads when the engine is in an idle state.

[0072] The embodiment of the present invention adjusts the rotational speed of the engine according to the number of currently opened high-power loads when the engine is in an idle state, so when the high-power load is opened, the rotational speed of the engine will incre...

Abstract

The invention discloses a management method and device for an automobile power source, and belongs to the field of automobile power sources. The management method comprises the steps that an opening signal and a closing signal of each large-power load are monitored, and each large-power load is a load with the power larger than a preset power; according to the monitored opening signal and closing signal of each large-power load, the number of opened large-power loads is determined; when an engine is in an idling state, the rotation speed of the engine is adjusted according to the number of the currently opened large-power loads. According to the management method and device for the automobile power source, when the engine is in the idling state, the rotation speed of the engine is adjusted according to the number of the currently opened large-power loads. Therefore, when the large-power loads are opened, the rotation speed of the engine is improved, the generation power of a generator provided with energy by the engine is further improved, discharging of the storage battery and decrease of the voltage of an electric system are avoided, and work stability of the electric system is guaranteed.

Description

technical field [0001] The invention relates to the field of automobile energy, in particular to an automobile power management method and device. Background technique [0002] With the increasing diversification of consumers' needs for communication and entertainment, the power consumption of automotive electrical systems is getting higher and higher, and the management of automotive power systems is becoming more and more important. [0003] The automotive power supply system includes an engine, a generator that provides energy from the engine and outputs electrical energy, a battery that outputs or stores electrical energy, and a load that consumes electrical energy. In order to meet the requirements for vehicle noise and fuel consumption, many cars currently define lower and lower speeds when the engine is idling. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] When...
