Problems solved by technology

[0004] However, when operating a plurality of virtual machines on a plurality of processors, there is a problem that it is appropriate to allocate each of the plurality of virtual machines to which processor.
[0005] The virtual machine system disclosed in Japanese Patent Application Laid-Open No. 2019-57162 above has the problem of being unable to dynamically change the allocation of virtual machines to processors.
[0006] In addition, in the system disclosed in the above-mentioned International Publication No. 2011 / 119444, when moving a virtual machine from a certain computer to another computer, only power consumption
Therefore, for example, when distributing a virtual machine running on a certain processor of an ECU (Electronic Control Unit) mounted on a vehicle to another processor, there is a problem that the state of the vehicle cannot be properly considered.
[0007] Therefore, in the prior art, when a plurality of virtual machines are operated on a plurality of processors mounted in a vehicle, there is a problem that power consumption cannot be reduced while considering the state of the vehicle.

no. 1 Embodiment approach ＞

[0044] figure 1 It is a figure which shows an example of the hardware structure of the vehicle control system 10 which concerns on 1st Embodiment. Such as figure 1 As shown, the vehicle control system 10 according to the first embodiment includes a vehicle-mounted sensor group 12 , an actuator group 14 , and an ECU (Electronic Control Unit) 16 as an example of a vehicle control device. Among them, the ECU 16 of the embodiment is an integrated ECU in which a plurality of functions are integrated.

[0045] In the present embodiment, a case where the vehicle equipped with the vehicle control system 10 is a plug-in hybrid vehicle that supports both external charging and engine power generation and is capable of both automatic driving and manual driving will be described as an example. . In addition, the vehicle control system 10 of the present embodiment can also be applied to gasoline vehicles, hybrid vehicles, or electric vehicles.

[0046] The ECU 16 includes a plurality of...

no. 2 Embodiment approach ＞

[0133] Next, a second embodiment will be described. However, since the configuration of the vehicle control system according to the second embodiment is the same as that of the first embodiment, the same reference numerals are assigned and description thereof will be omitted.

[0134] The vehicle control system 10 according to the second embodiment differs from the first embodiment in the determination method when changing the allocation of processors.

[0135] The operation of the vehicle control system 10 of the second embodiment will be described. The ECU 16 of the vehicle control system 10 of the second embodiment performs the same operation as that of the first embodiment whenever information output from the on-vehicle sensor group 12 is received. Figure 12 The vehicle control processing routine shown.

[0136] Similar to the first embodiment, the vehicle control system 10 of the second embodiment executes Figure 12 Step S100 to step S114. However, the assignment de...

Abstract

The invention relates to a vehicle control device, a vehicle control method, and a vehicle control program. When a plurality of virtual machines are operated on a plurality of processors mounted on a vehicle, the state of the vehicle can be considered and the power consumption can be reduced. An acquisition unit of an ECU (16) acquires a state of the vehicle. A change unit of the ECU (16) changes the assignment of the processors to the target virtual machines in accordance with the state of the vehicle acquired by the acquisition unit (44) so that the target virtual machine operating in the first processor operates in the second processor. A termination unit (52) of the ECU (16) terminates the operation of the first processor to which the assignment has been changed by the change unit (50).

Description

technical field [0001] The present disclosure relates to a vehicle control device, a vehicle control method, and a vehicle control program. Background technique [0002] Japanese Patent Laid-Open No. 2019-57162 discloses a virtualization system capable of suppressing communication delays between a virtual computer and hardware. In this virtualization system, VM cores (cores) 11a to 11c operate as ECUs that provide functions related to vehicle running control such as running, turning, and stopping. In addition, JP-A-2019-57162 discloses that the VM core 11a can operate as an ECU that provides functions of a multimedia system such as a navigation device, an audio device, and the like. In addition, JP-A-2019-57162 discloses that the VM core 11a can operate as an ECU of body systems such as seats and power windows. [0003] Also, International Publication No. 2011 / 119444 discloses a system for moving a virtual machine from the computer to another computer when there is a compu...
