  Exemplary embodiments of an electronic control device and an operation management device for managing the operation of the electronic control device according to the present invention will be described below in detail with reference to the accompanying drawings.

  First, the concept of the embodiment according to the present invention will be described with reference to FIG. In this embodiment, since the function executed by the electronic control unit (ECU) is changed in accordance with the situation of the host vehicle, the operation management device manages the function of the ECU.

  In FIG. 1, the operation management device 1 and the ECU 11 are connected via a bus 3. The operation management apparatus 1 is further connected to a hard disk drive (HDD) 2. The HDD 2 is a storage unit that stores various programs such as a navigation program 2a, an audio program 2b, and a security program 2c. In addition to the program, the HDD 2 stores various data such as map data and music data. The operation management device 1 determines a situation of the host vehicle, selects a necessary function, reads a program for realizing the function from the HDD 2, and sends the program to the ECU 11.

  For example, when the power state of the host vehicle is accessory on (ACC on: the ignition key is in the accessory on position (energized state of the on-vehicle electronic device such as audio) or the ignition on position), the vehicle is running. Alternatively, the traveling management device 1 reads out the navigation program 2a from the HDD 2 and sends it to the ECU 11. ECU11 implement | achieves the navigation function which guides the path | route to the destination by running the navigation program 2a.

  On the other hand, when the power supply of the own vehicle is in the accessory off (ACC off) state, the vehicle is stopped (parked), so the operation management device 1 reads the security program 2c from the HDD 2 and sends it to the ECU 11. The ECU 11 implements a security function for preventing vehicle theft by executing the security program 2c.

  As described above, the operation management device 1 switches the necessary function of the ECU 11 based on the power supply state, so that the ECU 11 has a necessary function according to the state, in this example, the navigation function when the ACC is on. When the ACC is turned off, a security function is provided.

  Next, the schematic configuration of the in-vehicle system according to the embodiment of the present invention is shown in the schematic configuration diagram of FIG. In the configuration shown in the figure, the operation management device 1, the ECUs 11 to 13, the input device 4, the output device 5, and the communication device 6 are connected to the bus 3. In addition to this, various information such as a power state, vehicle speed, weather, time, place, presence / absence of vibration, detection result by radar, and the like flow through the bus 3 from sensors and the like.

  The communication device 6 is a device used for communication with an external server or another vehicle, the output device 5 is an output device group such as a display or a speaker, and the input device 4 is an input device that receives input from a user such as a switch or a touch panel. Is a group. The communication device 6, the output device 5, and the input device 4 are shared by various in-vehicle devices including the operation management device 1 and the ECUs 11 to 13.

  The ECU 11 has a program receiving unit 11a and a program executing unit 11b therein. The program receiving unit 11 a is a processing unit that receives a program from the operation management unit 1. The program execution unit 11b includes a CPU and a memory as a hardware configuration, and performs a process of executing the program received by the program reception unit 11a.

  That is, the ECU 11 operates as a general-purpose electronic control device that bears a function provided by an arbitrary program transmitted from the operation management device 1 instead of a fixed specific function.

  The ECU 12 is a general-purpose electronic control device that has a program receiving unit 12 a and a program execution unit 12 b as with the ECU 11 and executes an arbitrary program transmitted from the operation management device 1. Similarly to the ECUs 11 and 12, the ECU 13 includes a program receiving unit 13 a and a program executing unit 13 b and operates as a general-purpose electronic control device that executes an arbitrary program transmitted from the operation management device 1.

  The operation management device 1 includes a situation determination unit 1a, an ECU state monitoring unit 1b, and a program control unit 1c. The situation determination unit 1a acquires information such as the power supply state from the bus 3 and determines the situation of the host vehicle. Further, the ECU state monitoring unit 1b monitors whether the operation states of the ECUs 11 to 13 are normal. As a method for determining whether or not the operation state is normal, for example, a test signal that returns a predetermined signal may be output, and the return signal may be compared with a normal signal.

  The program control unit 1c selects a necessary function based on the determination result by the situation determination unit 1a, reads a program for executing the function from the HDD 2, and transmits the program to the ECUs 11 to 12. At this time, if there are a plurality of transmission destination candidates, the monitoring result obtained by the ECU state monitoring 1b is used, and the normally operating ECU is set as the transmission destination. The operation management device 1 includes a CPU, a memory, an interface for bus communication, and the like, and performs the above-described processing. The power is directly supplied from the battery and is always operating.

  Next, the processing operation of the operation management apparatus 1 will be described. FIG. 3A and FIG. 3B are flowcharts for explaining the processing operation of the operation management apparatus 1 and are repeatedly executed while the operation management apparatus 1 is in operation. As illustrated in FIG. 3A, the situation determination unit 1a first acquires information indicating the power state from the bus 3 and determines whether or not the ACC is in an on state (step S101).

  As a result, if the ACC is on (step S101, Yes), the program control unit 1c transmits the navigation program 2a read from the HDD 2 to the ECU 11 for reading (step S102), and the audio program also read from the HDD 2 2b is transmitted to the ECU 12 for reading (step S103), and the process is terminated.

  On the other hand, if the ACC is off (step S101, No), then the state of the security program operation ECU setting by the user operation is determined, and if the ECU setting is "automatic" (step S120, Yes), the next Then, the ECU state monitoring unit 1b determines whether the ECU 11 is normal (step S104). If the ECU 11 is normal (step S104, Yes), the security program 2c read from the HDD 2 by the program control unit 1c is sent to the ECU 11. The data is transmitted and read (step S105), and the process ends.

  If the ECU 11 is not normal (step S104, No), the ECU state monitoring unit 1b determines whether the ECU 12 is normal (step S106). If the ECU 11 is normal (step S106, Yes), the program control unit The security program 2c read from the HDD 2 by the computer 1c is transmitted to the ECU 12 to be read (step S107), and the process is terminated.

  Further, if the ECU 12 is not normal (step S106, No), the ECU state monitoring unit 1b determines whether the ECU 13 is normal (step S109). If the ECU 12 is normal (step S109, Yes), the program The control unit 1c transmits the security program 2c read from the HDD 2 to the ECU 13 for reading (step S108), and the process is terminated.

  Further, if the ECU 13 is not normal (No at Step S109), it is notified that the security program 2c is inoperable due to ECU abnormality (Step S110), and the process is terminated.

  Next, when the state of the security program operation ECU setting by the user operation is not “automatic” (step S120, No) and “ECU11” (step S111, Yes), it is determined whether the ECU 11 is normal (step S112). If it is normal (step S112, Yes), the program control unit 1c transmits the security program 2c read from the HDD 2 to the ECU 11 for reading (step S113), and the process is terminated.

  If the ECU 11 is not normal (No at Step S112), the security program 2c is inoperable due to an abnormality in the ECU (Step S110), and the process ends.

  Next, when the state of the security program operation ECU setting by the user operation is not “ECU11” (No in step S111) and “ECU12” (step S114, Yes), it is determined whether the ECU12 is normal (step S115). If it is normal (step S115, Yes), the program control unit 1c transmits the security program 2c read from the HDD 2 to the ECU 12 for reading (step S116), and the process is terminated.

  If the ECU 12 is not normal (No at Step S115), the security program 2c is inoperable due to ECU abnormality (Step S110), and the process is terminated.

  Next, when the security program operation setting state by the user operation is not “ECU12” (step S114, No) and “ECU13” (step S117, Yes), it is determined whether the ECU 13 is normal (step S118). If it is normal (step S118, Yes), the program control unit 1c transmits the security program 2c read from the HDD 2 to the ECU 13 for reading (step S119), and the process is terminated.

  If the ECU 13 is not normal (No at Step S118), the security program 2c is inoperable due to an abnormality in the ECU (Step S110), and the process ends.

  Next, when the state of the security program operation ECU setting by the user operation is not “ECU13” (No in step S117), the process is terminated.

  As described above, the operation management device 1 transmits a program to each ECU according to the power supply state, so that the navigation function and the audio function can be executed when the ACC is on, and the security function can be executed when the ACC is off. Therefore, the number of ECUs can be reduced as compared with a configuration in which a dedicated ECU is provided for each function, and the configuration can be downsized and the ECU can be used efficiently.

  For example, when the navigation program 2a is read, the ECU 11 obtains information such as location and time from the bus 3 and executes route guidance. When the security program 2c is read, the ECU 11 detects vibration and radar from the bus 3. Information such as results is acquired to detect the occurrence of vehicle theft.

  Further, even when an abnormality has occurred in any ECU, the security function is executed by selecting a normal ECU, so the reliability of the security function can be improved.

  In the above description, the case where a necessary function is selected based on the power supply state has been described. However, the situation determination by the situation determination unit 1a can be executed using not only the power supply state but also arbitrary information.

  A specific example of the situation determination and the function to be selected is shown in FIG. As shown in the figure, in the situation judgment using the vehicle speed information, a high-speed tracking control program that keeps the distance between the preceding vehicle and the preceding vehicle on the expressway is selected if the speed is higher than the predetermined speed, and if the speed is lower than the predetermined speed, the general road For example, select a low-speed tracking control program that prevents accidents by leaving an interval with the preceding vehicle.

  In the situation determination using the weather information, a sunroof control program for opening and closing the sunroof is selected when it is clear, and a wiper control program for controlling the operation of the wiper is selected when it is raining.

  Similarly, in the situation determination using the time information, a function that is highly likely to be operated in that time zone is selected based on, for example, designation from the user or an operation history (stored in the HDD 2). In FIG. 4, the radio reception program is selected from 7:00 am to 8:00 am, and the content reproduction program in the HDD for reproducing the content data such as music data stored in the HDD 2 is selected during other time periods. It is said.

  In addition, in the situation judgment using location information, normal mode engine control that executes normal engine control is selected on general roads and expressways, and power mode engine control that executes engine control suitable for running on slopes in mountainous areas. Select. This determination is based on map data (stored in the HDD 2 or read from a recording medium such as a DVD or CD-R) for realizing a navigation function and own vehicle position data from a own vehicle position detector such as GPS. Can be done.

  In this way, by determining in detail the situation of the host vehicle using various information, a necessary function can be selected and allocated to the ECU, and the configuration can be reduced by further reducing the number of ECUs.

  Next, a modification of the in-vehicle system will be described. In the configuration shown in FIGS. 1 and 2, the operation management unit 1 is directly connected to the HDD 2, and a program that realizes a necessary function is read from the HDD 2 and transmitted to the ECUs 11 to 13. Then, the ECUs 11 to 13 can read a necessary program directly from the HDD 2.

  FIG. 5 shows a configuration example when the ECU directly reads the program from the HDD. In the figure, the operation management device 7, the HDD 8, and the ECU 14 are connected to the bus 3. And ECU14 has the reading process part 14a and the program execution part 14b in the inside.

  In this configuration, the operation management device 7 determines the situation of the host vehicle, selects a necessary function, and requests the ECU 14 to read a program that realizes the selected function (1. read request).

  Upon receiving a read request from the operation management device 7, the read processing unit 14a in the ECU 14 accesses the HDD 8 (2. HDD access) and causes the program execution unit 14b to read the designated program (3. program read). .

  Thus, by reading and executing the program designated from the operation management device 7, the ECU 14 can operate as a general-purpose electronic control device that provides a function according to the situation.

  Further, the ECU does not necessarily need to be a general-purpose processing device, and can be implemented as a configuration in which an ECU having a specific function temporarily executes another function. A configuration example in this case is shown in FIG.

  In the configuration shown in the figure, the operation management device 9, the navigation ECU 15, the audio ECU 16, the input device 4, the output device 5, and the communication device 6 are connected to the bus 3. In addition to this, various information such as the power state, vehicle speed, weather, time, place, presence / absence of vibration, detection result by the radar, etc., flow from the various sensors to the bus 3.

  The navigation ECU 15 includes a navigation function 15a for guiding a route to a destination therein and an external function execution unit 15b for executing an arbitrary function designated by the operation management unit 9.

  That is, the navigation ECU 15 provides a navigation function in a normal state (for example, ACC on state), but when the navigation is not necessary (for example, when ACC is off), the external function execution unit 15b temporarily performs other functions. Can be provided.

  Similarly, the audio ECU 16 includes therein an audio function 16a that performs broadcast reception and content reproduction, and an external function execution unit 15b that executes an arbitrary function designated by the operation management unit 9. Therefore, an audio function can be provided in a normal state (for example, ACC on state), and another function can be temporarily provided by the external function execution unit 15b in a state where the audio function is not necessary (for example, ACC off state). .

  The operation management device 9 determines the state of the host vehicle by the internal state determination unit 9a, and the ECU state monitoring unit 9b monitors the operation states of the navigation ECU 15 and the audio ECU 16. Then, the program control unit 9c selects a necessary function based on the determination result by the situation determination unit 1a, and the ECU that can assign the function selected based on the monitoring result by the ECU state monitoring unit 9b, that is, operates normally. And a program is transmitted to ECU of the state which does not require an original function.

  For example, when the situation determination unit 9a detects that the ACC is off, the program control unit 9c reads the security program 2c from the HDD 2 and transmits it to the navigation ECU 15 or the audio ECU 16.

  In this way, even an ECU having a predetermined specific function can execute an arbitrary function designated from the outside, thereby reducing the number of ECUs and reducing the configuration in size and efficiency. The ECU can be used. Further, even when an abnormality occurs in any ECU, reliability can be improved by selecting a normal ECU and assigning functions. In addition, engine control that requires advanced and reliable control (control of functions that will not be able to run if an abnormality occurs, causing serious trouble) is dedicated, and an abnormality occurs by having the program stored in the internal ROM etc. Even if an abnormality occurs, the vehicle does not become incapable of running, and control with a relatively light influence is assigned to each ECU, so that certainty and efficiency can be realized in a balanced manner.

  As described above, the operation management device according to the present embodiment determines a vehicle condition, selects a necessary function, reads a program for realizing the function from the HDD, and sends the program to the electronic control unit. The number of ECUs can be reduced as compared with a configuration in which a dedicated ECU is provided, and the configuration can be reduced in size and the ECU can be used efficiently.

  Then, the operation state of the electronic control device is monitored, and reliability can be improved by setting the electronic control device that is operating normally among the plurality of ECUs as the transmission destination of the program. Further, even an electronic control device having a specific function can contribute to the reduction of the ECU and the downsizing of the configuration by enabling execution of an arbitrary function designated from the outside.

  As described above, the on-vehicle electronic control device and the operation management device according to the present invention are useful for operation control of the vehicle and various on-vehicle devices, and are particularly suitable for the operation management of the electronic control device in a vehicle equipped with various functions.
