Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation. The embodiments and features of the embodiments of the present invention may be combined with each other without conflict.
As shown in fig. 1, a flowchart of a power control method according to an exemplary embodiment of the present disclosure is shown, and the method includes the following steps:
in step S11, detecting a remaining capacity of a battery of a vehicle when the vehicle is in an idle condition;
in step S12, when the remaining capacity is equal to or less than a first preset capacity, controlling an engine of the vehicle to increase an idle speed so as to charge the battery;
in step S13, the engine is controlled to return the idle speed to an initial idle speed before increasing the idle speed when the remaining amount of electricity of the battery after charging is equal to or greater than a second preset amount of electricity.
As shown in fig. 2, a vehicle electric quantity control system according to an exemplary embodiment of the present disclosure includes: a battery 21; a charge amount sensor 22 for collecting a remaining charge amount of the battery 21; an electronic control unit 23 connected to the electric quantity sensor 22; an engine 24 connected to the electronic control unit 23; a generator 25 connected to the engine 24 and the battery 21, respectively; the rotational speed sensor 26 is connected to the engine 24. The electronic control unit 23 is capable of receiving the remaining power of the battery collected by the power sensor 22, and generating a control signal according to the remaining power of the battery to control the rotation speed of the engine. When the engine 24 rotates, the generator 25 can be driven to work to charge the battery. The rotation speed sensor 26 is capable of detecting the rotation speed of the engine.
In the present disclosure, the engine may be the engine 24 shown in fig. 2, and the idle condition is a condition where the engine 24 is operating under no load. During idle conditions, the remaining capacity of the battery may be monitored by a charge sensor 22 provided on the battery. When the remaining power is less than or equal to the first preset power, it indicates that the current remaining power may not meet the power demand of the entire vehicle, at this time, the electronic control unit 23 generates a control signal for increasing the idle speed and sends the control signal to the engine 24, and the engine 24 increases the idle speed according to the control signal to increase the power generation amount of the generator 25 and charge the battery 21.
The first preset electric quantity can be set according to the electric quantity of the whole vehicle, the service durability evaluation of the battery and the like, and the disclosure is not limited. For example, the first preset electric quantity is 75%, and when the residual electric quantity of the battery is less than or equal to 75%, the engine is controlled to increase the idle speed.
The mode of increasing the idle speed may be set according to actual needs. In one embodiment, increasing the idle speed may increase the initial idle speed by controlling the engine to a predetermined speed, such as by 50rpm/min or 100 rpm/min. In another embodiment, the idle speed may be increased by controlling the engine to output a preset speed, for example, the initial idle speed is 600rpm/min, and the preset speed is 800rpm/min, and then when the remaining capacity of the battery is less than or equal to the first preset capacity, the speed of the engine is adjusted from 600rpm/min to 800 rpm/min. In the present disclosure, the electronic control unit 23 may control the engine to increase the idle speed by the rotation speed signal sent by the rotation speed sensor 26.
After the idle speed is improved, generator 25 to the battery charges, the residual capacity of battery increases gradually, and when the residual capacity after charging more than or equal to the second preset electric quantity, it shows that the residual capacity can satisfy current whole car power consumption demand, at this moment, can resume the idle speed to initial idle speed to reduce the oil consumption and discharge. The second preset electric quantity can be set according to actual needs, for example, the second preset electric quantity can be 90%, 95% and the like, the first preset electric quantity and the second preset electric quantity can be the same or different, and the disclosure is not limited.
It should be understood that the scheme in the present disclosure may be adopted in the case that increasing the idle speed does not affect the operation of the whole vehicle, and when increasing the idle speed has an effect on the current operation, the engine is controlled to return to the initial idle speed. For example, the current operation is that the brake pedal is depressed, and at this time, the engine returns to the initial idle rotation speed so that the entire vehicle responds to the operation that the brake pedal is depressed, in order not to affect the current operation.
As shown in fig. 3, a flowchart of a method for increasing idle speed according to a speed range is shown for an exemplary embodiment of the present disclosure, the method comprising:
in step S31, determining a maximum idle speed of the engine according to a noise level of the engine under the idle condition;
in step S32, determining a minimum idle speed of the engine based on a power demand of the vehicle;
in step S33, a rotation speed range for increasing the idle rotation speed is determined based on the maximum idle rotation speed, the minimum idle rotation speed, and the initial idle rotation speed.
In step S34, when the remaining capacity is equal to or less than the first preset capacity, the engine is controlled to increase an idle speed according to the speed range.
In the present disclosure, the Noise level may be Noise, Vibration and Harshness (NVH), the NVH can directly affect the riding feeling of the user, and the NVH may be deteriorated as the idle speed of the vehicle increases. In one embodiment, to ensure the ride quality of the user, NVH is required to be less than or equal to 65dBA + -5 dBA, and the maximum idle speed P that the engine can provide is selected when the NVH is ensured to be within the range.
In addition, a minimum idle speed M of the engine is determined according to a power consumption demand of the vehicle. In one embodiment, the current electrical equipment of the vehicle is an air conditioner, and the minimum idle speed can meet the power demand of the air conditioner. When the current electric equipment of the vehicle is an air conditioner and a lamp, the minimum idle speed is the minimum speed capable of meeting the power consumption requirements of the air conditioner and the lamp.
As can be seen from the above, when the initial idle speed of the vehicle is F, the maximum speed at which the idle speed can be increased is P-F, and the minimum speed at which the idle speed can be increased is M-F, so that the speed range N at which the idle speed can be increased can be determined as: M-F is not less than N and not more than P-F. In the rotating speed range, the NVF level of the whole vehicle can reach the optimal level, and the power consumption requirement of the whole vehicle can be met.
Correspondingly, when the residual electric quantity is less than or equal to the first preset electric quantity, the engine is controlled to increase the idle speed according to the rotating speed range. That is, the rotational speed is selected as the increment for raising the idle rotational speed in the rotational speed range. For example, the rotation speed range is 50rpm/min ≦ N ≦ 200rpm/min, the initial idle rotation speed F is 600rpm/min, and when the idle rotation speed needs to be increased, a rotation speed increment may be selected within the rotation speed range, for example, 50rpm/min, and the initial idle rotation speed is increased by 50rpm/min, and then the idle rotation speed is 650 rpm/min.
Optionally, the method further comprises: detecting the power consumption of the current electric equipment of the vehicle; and determining the ratio of the power utilization power to the total power utilization power of all the power utilization equipment of the vehicle when the power utilization equipment is turned on. And when the residual electric quantity is less than or equal to the first preset electric quantity, controlling the engine to increase the idle speed according to the ratio and the speed range.
The power consumption power of the current electric equipment can be acquired by various electric equipment sensors, and the total power consumption power can be stored in a memory of the vehicle in advance when the vehicle leaves a factory. When the remaining capacity is less than or equal to the first preset capacity, controlling the engine to increase the idle speed according to the ratio and the speed range, including: determining a rotational speed increment corresponding to the ratio in the rotational speed range; controlling the idle speed of the engine to increase from the initial idle speed by the speed increment.
In order to reasonably control the residual electric quantity and meet the current power consumption requirement of the whole vehicle, different idle speed increments can be set corresponding to the current power consumption power of the current power consumption equipment and the power consumption total power according to different ratios. In one embodiment, the rotation speed range may be segmented, for example the rotation speed range N is: n is more than or equal to 50rpm/min and less than or equal to 150rpm/min, and the rotating speed range can be divided into three sections, namely 50rpm/min, 100rpm/min and 150 rpm/min. When the range of the ratio A is more than 0 and less than or equal to 40 percent, selecting the increment of the idle speed as 50rpm/min, when the range of the ratio A is more than 40 percent and less than or equal to 70 percent, selecting the increment of the idle speed as 100rpm/min, and when the range of the ratio A is more than 70 percent and less than or equal to 100 percent, selecting the increment of the idle speed as 150 rpm/min. Of course, the segment of the rotating speed range may be selected according to actual needs, for example, the rotating speed range is divided into 4 segments, 5 segments, and the like, and the difference between adjacent rotating speed increments may be the same or different, and the disclosure is not limited.
Optionally, before controlling the engine to recover the idle speed to the initial idle speed when the remaining capacity of the battery after charging is greater than or equal to a second preset capacity, the method further includes: and determining the electric quantity corresponding to the ratio as the second preset electric quantity according to the ratio and the corresponding relation between the preset ratio and the electric quantity.
The ratio can indicate the current power demand of the whole vehicle, and the larger the ratio is, the larger the power consumption of the current electric equipment is, so that the second preset electric quantity can be set according to different power demands, the relation between the ratio and the second preset electric quantity can be stored in a corresponding relation table in advance, and after the ratio is determined, the corresponding second preset electric quantity is directly searched in the corresponding relation table. Continuing with the above example, when the range of the ratio a is 0 < a ≦ 40%, the second preset electric quantity is determined to be 90% in the correspondence table, when the range of the ratio a is 40% < a ≦ 70%, the second preset electric quantity is determined to be 95% in the correspondence table, and when the range of the ratio a is 70% < a ≦ 100%, the second preset electric quantity is determined to be 100% in the correspondence table. Of course, the corresponding relationship between the ratio and the electric quantity can be set according to actual needs.
Optionally, the method further comprises: upon detection of a running operation for the vehicle, an idle rotation speed of the engine is restored to the initial idle rotation speed to cause the vehicle to respond to the running operation.
In the disclosure, in order that the electric quantity control does not have any influence on the driving of the whole vehicle, when the driving operation of the vehicle is detected, such as the brake pedal is pressed down, the accelerator pedal is pressed down, and the like, the engine returns to the initial idle speed so that the vehicle responds to the driving operation. When the vehicle returns to the idle condition again, the electric quantity control method in the disclosure is executed again.
In addition, when the engine of the vehicle is restarted after flameout, in order to ensure the reliable operation of the engine, the electric quantity control method in the disclosure is executed again, and the engine does not continue the working condition state before flameout. For example, the engine is in a state of increasing the idle rotation speed before a shut down, the engine is operated at the initial idle rotation speed when a restart is performed, and the engine is increased the idle rotation speed when a remaining power amount is detected to be less than a first preset power amount, without being operated at the increased idle rotation speed before the shut down at the time of the start.
