Abstract

To propose a technology for suppressing consumption power of an on-vehicle communication system.SOLUTION: A vehicle comprises a vehicle theft prevention alarm and an on-vehicle communication system. The on-vehicle communication system executes intermittent action of repeatedly executing communication operations with a quiescent time being interposed and makes the quiescent time be longer in a first period of the first period and a second period which are set in a day than that in the second period except when the vehicle theft prevention alarm is outputting a warning. The vehicle can set the first period when a use frequency of a user is low and set the second period when the use frequency of the user is high. The on-vehicle communication system shorten the quiescent time in the second period. Therefore, a real-time property of communication can be implemented. In the first period, the on-vehicle communication system elongates the quiescent time except when the vehicle theft prevention alarm is outputting a warning. Therefore, consumption power of the on-vehicle communication system can be suppressed.SELECTED DRAWING: Figure 3

Description

[Technical Field]

[0001] The technology disclosed in this specification relates to vehicles. [Background technology]

[0002] An in-vehicle communication system is installed in the vehicle of Patent Document 1. When a user operates a mobile terminal, the in-vehicle communication system performs wireless communication via a network. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-146874 Summary of the Invention [Problem to be solved by the invention]

[0004] This specification proposes a technology for reducing power consumption in an in-vehicle communication system. [Means for solving the problem]

[0005] The vehicle disclosed in this specification comprises a vehicle anti-theft alarm and an on-board communication system, wherein the on-board communication system performs intermittent operation in which communication operations are repeatedly performed with pauses in between, and during the first period of a first and second period set within a day, the pause time is longer than during the second period, except when the vehicle anti-theft alarm is outputting a warning.

[0006] The output of the warning by the vehicle anti-theft alarm may be an operation of sounding a warning sound or an operation of transmitting a warning signal to the outside.

[0007] In the above vehicle, a first period can be set when the user's use frequency is low, and a second period can be set when the user's use frequency is high. During the second period when the user's use frequency is high, the in-vehicle communication system shortens the pause time. This enables real-time communication. During the first period when the user's use frequency is low, the in-vehicle communication system lengthens the pause time, except when the vehicle anti-theft alarm is outputting a warning. A long pause time reduces the real-time communication, but since the user's use frequency is low, low real-time communication does not cause any problems in convenience. Furthermore, by lengthening the pause time, the power consumption of the in-vehicle communication system can be reduced. Furthermore, when the vehicle anti-theft alarm is outputting a warning, the in-vehicle communication system shortens the pause time to increase the real-time communication, thereby achieving high security. [Brief explanation of the drawings]

[0008] [Figure 1] FIG. [Figure 2] 10 is a flowchart executed by the control device. [Figure 3] FIG. 2 is an explanatory diagram of a period during which each operation is performed. DETAILED DESCRIPTION OF THE INVENTION

[0009] 1 includes a vehicle anti-theft alarm 10 and an in-vehicle communication system 20. The vehicle anti-theft alarm 10 outputs a warning when there is a possibility that the vehicle 100 may be stolen. The output of the warning by the vehicle anti-theft alarm 10 may be an operation of sounding a warning sound or an operation of transmitting a warning signal to the outside.

[0010] The in-vehicle communication system 20 performs wireless communication with a mobile terminal (e.g., a smartphone) carried by a user. The user can check the status of the vehicle 100 or control the vehicle 100 by accessing the in-vehicle communication system 20 via the mobile terminal. For example, the user can check the remaining battery charge of the vehicle 100 via the mobile terminal. Furthermore, for example, the user can start the engine of the vehicle 100 via the mobile terminal. The in-vehicle communication system 20 repeatedly performs communication with the mobile terminal. Between communications, there is provided a pause period during which communication with the mobile terminal is not performed. In other words, the in-vehicle communication system 20 performs intermittent operation in which communication is repeatedly performed with a pause period in between.

[0011] The in-vehicle communication system 20 includes a control device 22 and a storage device 24. The control device 22 executes communication while changing the pause time.

[0012] The storage device 24 stores a first period and a second period set within a day. The first period and the second period may be set by the manufacturer of the vehicle 100 or by the user. The first period is set to a period (e.g., night) when the user uses the in-vehicle communication system 20 less frequently. The second period is set to a period (e.g., morning) when the user uses the in-vehicle communication system 20 more frequently. The first period and the second period may be permanently stored in the storage device 24, or the storage device 24 may temporarily store the first period and the second period acquired through communication with an external server.

[0013] The control device 22 executes the process shown in the flowchart of Fig. 2. The control device 22 acquires the current time in step S1. In step S2, the control device 22 determines whether the current time is in the first period or the second period.

[0014] If the current time is in the first period, the control device 22 determines in step S4 whether the vehicle anti-theft alarm 10 is outputting a warning. If the vehicle anti-theft alarm 10 is not outputting a warning (NO in step S4), the control device 22 sets the pause time to a long time t1 in step S6. Therefore, as shown in Fig. 3, in the first period, the pause time is the long time t1 except when the vehicle anti-theft alarm 10 is outputting a warning.

[0015] If it is determined in step S2 that the current time is in the second period, or if it is determined in step S4 that the vehicle anti-theft alarm 10 is sounding (i.e., YES), the control device 22 sets the pause time to time t2, which is shorter than time t1, in step S8. Therefore, as shown in Fig. 3, the pause time is the short time t2 during the second period and the period when the vehicle anti-theft alarm 10 is outputting a warning.

[0016] If the pause time is long, the communication frequency decreases, allowing the in-vehicle communication system 20 to reduce power consumption. However, if the pause time is long, the real-time nature of communication decreases. In this embodiment, during the first period, which is a period in which the user's frequency of use is low, the control device 22 lengthens the pause time except when the vehicle anti-theft alarm 10 is outputting an alarm. Since the user's frequency of use is low, low real-time nature of communication does not pose a problem. Furthermore, by lengthening the pause time, the power consumption of the in-vehicle communication system 20 can be reduced. Furthermore, when the vehicle anti-theft alarm 10 is outputting an alarm (i.e., when there is a possibility that the vehicle 100 may be stolen), high real-time nature of communication is important. Therefore, even during the first period, when the vehicle anti-theft alarm 10 is outputting an alarm, the pause time is shortened to increase the real-time nature of communication. Furthermore, in this embodiment, during the second period, when the user's frequency of use is high, the pause time is shortened to increase the real-time nature of communication. Therefore, the user can smoothly access the in-vehicle communication system 20.
