Description

  The present invention relates to an in-vehicle power saving control apparatus that saves power consumption of an in-vehicle battery in a vehicle.

  Many in-vehicle electrical components are mounted on the vehicle, and the power consumption of the in-vehicle battery is increasing with the progress of electric drive. However, since the capacity of the in-vehicle battery is finite, it is necessary to minimize power consumption. Therefore, the battery monitoring ECU is activated only when an abnormal discharge is detected by detecting the current consumed by the on-board battery when the electrical components at the time of parking are in a sleep state where normal functions other than some functions are stopped. An onboard battery monitoring system is disclosed (for example, Patent Document 1). The battery monitoring ECU performs control such as determination of an abnormal location and interruption of power supply to the electrical component in which the abnormality has occurred.

If the current consumption in the normal state is detected as abnormal discharge, the power supply to the electrical component may be cut off despite the necessity of providing the normal function of the electrical component. If it is not detected as abnormal discharge, the capacity of the in-vehicle battery may be depleted with no abnormal discharge detected.

  The in-vehicle power-saving control device according to claim 1 sets a detection means for detecting ignition off of the vehicle, and an upper limit value of current consumption of electrical components fed from the vehicle battery when the ignition off is detected. Setting means, current consumption amount acquisition means for repeatedly acquiring the current consumption amount of electrical components, integrated value acquisition means for acquiring an integrated value of the repeatedly acquired current consumption amount, and the integrated value exceeds the upper limit value of current consumption And stopping means for stopping the operation of the electrical component via in-vehicle communication.

  The in-vehicle power control information communication device 100 as the in-vehicle power saving control device in the embodiment described above has the following operational effects.

(1) The in-vehicle power control information communication device 100 includes a control device 215 and an in-vehicle communication device 210. The control device 215 includes an ignition signal detection processing unit 2151, an electrical component current consumption upper limit setting processing unit 2152, An electrical component consumption current amount acquisition control processing unit 2153, an electrical component consumption current amount integration processing unit 2154, and an electrical component operation stop control processing unit 2155 are included.

  The ignition signal detection processing unit 2151 of the control device 215 detects the ignition off of the vehicle 10. When the ignition-off is detected, the electrical component current consumption upper limit setting processing unit 2152 of the control device 215 causes the electrical components such as the air conditioner 120, the navigation device 130, and the electronic key unit 140 to be fed from the battery 115 of the vehicle 10. Set the upper limit of current consumption. The electrical component current consumption amount acquisition control processing unit 2153 of the in-vehicle communication device 210 and the control device 215 repeatedly acquires the current consumption amount of electrical components. The electrical component consumption current amount integration processing unit 2154 of the control device 215 acquires the integration value of the consumption current amount acquired repeatedly. The electrical component operation stop control processing unit 2155 of the control device 215 stops the operation of the electrical component via in-vehicle communication using the in-vehicle communication device 210 in the in-vehicle communication network 150 when the integrated value exceeds the upper limit value of current consumption. Let Therefore, when it is necessary to provide normal functions of the electrical components such as the air conditioner 120, the navigation device 130, and the electronic key unit 140 even when the vehicle 10 is parked, the provision of the battery 115 is performed within a range in which the capacity of the battery 115 is not exhausted. It becomes possible.

(2) When the electrical component consumption current amount acquisition control processing unit 2153 repeatedly acquires the current consumption amount and the electrical component is operating, the current that the air conditioner 120, the navigation device 130, and the electronic key unit 140 have The measured value of the meter is acquired as the amount of current consumption from the air conditioning control device 121, the navigation device 130, and the electronic key control device 141. Therefore, in-vehicle power saving control based on the accurate current consumption amount of each electrical component is possible.

(3) The electrical component current consumption upper limit setting processing unit 2152 of the control device 215 sets the current consumption upper limit value corresponding to each electrical component such as the air conditioner 120, the navigation device 130, and the electronic key unit 140. . When the electrical component operation stop control processing unit 2155 controls the electrical component control device to stop the operation of the electrical component, step S340 in FIG. 3 among the air conditioner 120, the navigation device 130, and the electronic key unit 140 is performed.

Control to stop. Therefore, in-vehicle power saving control is performed as designed.

  A modification of the in-vehicle power saving control device in the above-described embodiment of the present invention will be described below.

(1) The in-vehicle power control information communication device 100 as the in-vehicle power saving control device in the above-described embodiment has the table in FIG. 4 when the current consumption upper limit value of the electrical component is set in step S325 in FIG. The upper limit value of the current consumption amount of each electrical component registered in 400 is set as it is. However, with the current consumption upper limit value of each electrical component registered in the table 400 of FIG. 4 as the reference value, the current consumption upper limit value is set according to the reference value and the power supply capacity setting of the battery 115. It is good.

  FIG. 5 is a diagram showing a flowchart showing the electric current consumption upper limit setting processing procedure of the electrical component in this modification, and shows a portion sandwiched by points A and B before and after step S325 in the flowchart shown in FIG. ing. The processing before point A and the processing after point B are the same as in FIG.

  When an affirmative determination is made in step S315 immediately before point A, in step S510, the electric component consumption current amount upper limit setting processing unit 2152 of the control device 215 causes the electric components such as the air conditioner 120, the navigation device 130, and the electronic key unit 140 to be used. Is obtained by reading the table 400 of FIG. 4 from the storage device 225.

  In step S515, the battery information processing unit 2156 of the control device 215 controls the in-vehicle communication device 210 and acquires the power supply capacity setting information of the battery 115 from the battery control device 116 via the in-vehicle communication network 150. The power supply capacity setting information of the battery 115 is information regarding the use mode setting of the battery 115 such as an eco mode, a full operation mode, a long life mode, a normal mode, and the like.

  In step S325, as described above, the electrical equipment current consumption upper limit setting processing unit 2152 of the control device 215 sets the current consumption upper limit values of electrical equipment such as the air conditioner 120, the navigation device 130, and the electronic key unit 140. Set. At that time, the electric component consumption current amount upper limit value setting processing unit 2152 uses the reference value of the electric component consumption current amount upper limit value acquired in step S510 and the power supply capability setting information of the battery 115 acquired in step S515. Accordingly, the upper limit value of the current consumption amount of the electrical component is set. For example, when the power supply capacity setting information of the battery 115 acquired in step S515 indicates the eco mode, all the items registered in the table 400 indicating the reference value of the current consumption upper limit value of the electrical component acquired in step S510 are displayed. A value obtained by multiplying each value by 0.8 is set as the upper limit value of the current consumption amount of the electrical component.

(2) The in-vehicle power control information communication device 100 as the in-vehicle power saving control device in the above-described embodiment has the current that each electrical component has when the current consumption amount of the electrical component is acquired in step S330 of FIG. It was decided that data representing the total measured values would be collected. However, if the current consumption amount of an electrical component that is in a function-restricted state such as a sleep state is specified as a predetermined value in advance even if the measured value is not collected, the predetermined value is the electrical component. It may be acquired as the amount of current consumption. The sleep state is a state in which some of the functions of the electrical component are restricted. For example, standby current is consumed because only reception of a wake-up message is waited via the in-vehicle communication network 150. State. In this case, if the standby current amount is specified in advance as the predetermined value, the standby current amount is acquired as the current consumption amount of the electrical component. FIG. 6 shows the above-mentioned predetermined value, that is, the amount of current consumption per unit time in the function restricted state of each electrical component. As shown in the table 600 of FIG. 6, the predetermined values are, for example, 10 [mA · sec] for the air conditioner 120, 3 [mA · sec] for the navigation device 130, and the electronic key unit 0.1 [ mA · sec], and the table 600 is stored in the storage device 225.

When the electrical components such as the air conditioner 120, the navigation device 130, and the electronic key unit 140 transition from the normal state to the function restricted state, the air conditioning control device 121, the navigation device 130, and the electronic key control device 141 each perform in-vehicle communication. The function restriction state transition notification data is transmitted to the in-vehicle communication device 210 of the in-vehicle power control information communication device 100 via In response to the reception of the function restriction state transition notification data, the control device 215 of the in-vehicle power control information communication device 100 can store the fact that each electrical component is in the function restriction state. The device 215 can determine whether or not each electrical component is in a function restriction state. If the determination is negative, the process proceeds to step S720. If the determination is affirmative, the process proceeds to step S730.

  In step S720, as described above, the electrical component consumption current amount acquisition control processing unit 2153 of the control device 215 can acquire the measured value of the ammeter of each electrical component as the current consumption amount of each electrical component. The in-vehicle communication device 210 is controlled so that it can be performed.

  In step S730, the electrical component consumption current amount acquisition control processing unit 2153 refers to the storage device 225, for example, sets a predetermined value as shown in FIG. Get as a quantity.

(3) The consumption current determined for each electrical component such as the air conditioner 120, the navigation device 130, and the electronic key unit 140 is stored in the table 400 in which the upper limit value of the consumed current amount of the electrical component in the above-described embodiment is registered. The amount upper limit was to be registered. However, a plurality of current consumption upper limit values for all of the plurality of electrical components may be provided in stages. FIG. 8 is a diagram illustrating an example in which the upper limit value of the current consumption amount of the entire three electrical components such as the air conditioner 120, the navigation device 130, and the electronic key unit 140 is provided in two or three stages.

  In the table 810 shown in FIG. 8A, the minimum value 50,000 [mAh] as the first current consumption amount upper limit value of all three electrical components, and the maximum value 100,000 [mAh] as the second current consumption amount upper limit value. ] Is registered. The table 810 is stored in the storage device 225.

In this case, the electrical component operation stop control processing unit 2155 of the control device 215 controls the operation of one of the electrical components from the operation of the other electrical components according to the frequency of use and the amount of current consumption per unit time. Is also controlled to stop preferentially. When the integrated value exceeds the maximum value 100,000 [mAh] that is the second current consumption amount upper limit value, the electrical component operation stop control processing unit 2155 of the control device 215 is configured to stop the operation of all electrical components. Control.

The table 820 is stored in the storage device 225.

  As a result of integrating the consumption current amounts of the three electrical components by the electrical component consumption current amount integration processing unit 2154 of the control device 215, the integrated value exceeds the minimum value 50,000 [mAh] which is the first consumption current amount upper limit value. In this case, the electrical component operation stop control processing unit 2155 of the control device 215 controls the operation of one of the electrical components from the operation of the other electrical components according to the frequency of use and the amount of current consumption per unit time. Is also controlled to stop preferentially. When the integrated value exceeds the intermediate value 80,000 [mAh], which is the upper limit value of the second current consumption amount, two electrical components in operation according to the frequency of use and the amount of current consumption per unit time Control is performed so that the operation of any one of the electrical components is preferentially stopped over the operation of the other electrical component. When the integrated value exceeds the maximum value 100,000 [mAh] that is the third current consumption amount upper limit value, the electrical component operation stop control processing unit 2155 of the control device 215 stops the operation of all electrical components. Control.

  An example of priority control in the operation stop control of the electrical component described above will be described with reference to FIG. FIG. 9 is a diagram exemplifying a table 900 in which setting values relating to the frequency of use of three electrical components such as the air conditioner 120, the navigation device 130, and the electronic key unit 140 and the current consumption amount per unit time are registered.

  For example, when the electrical component operation stop control using the table 810 shown in FIG. 8A is performed, priority control based on the use frequency registered in the table 900 shown in FIG. 9 is performed. When the integrated value of the current consumption amounts of the three electrical components exceeds the minimum value of 50,000 [mAh], which is the upper limit value of the first current consumption amount, the electronic key unit 140 registered in the table 900 as being less frequently used.
