Onboard electronic control unit configured to perform an operation check

A computer program product comprising a non-transitory, machine-readable medium storing instructions which, when executed by at least one programmable processor, causes at least one programmable processor to perform operations comprising:

• referring to a storage unit configured to store a control program for controlling an onboard apparatus, an inspection program for performing an operation check of the onboard apparatus or an onboard Electronic Control Unit (“ECU”) for controlling the onboard apparatus, and validity information indicating whether the inspection program is valid or invalid;
• executing the inspection program if the validity information indicates that the inspection program is valid;
• and
• executing the control program if the validity information indicates that the inspection program is invalid,
• wherein the storage unit stores a boot program that is executed when the onboard ECU is started,
• the storage unit includes a first region accessible by a control unit that is executing the control program, and a second region to which access by the control unit that is executing the control program is restricted,
• the validity information is stored in the second region,
• the control unit that is executing the boot program accesses the second region using a physical address,
• the control unit that is executing the control program writes log data of control or drive of the onboard apparatus, in the first region, and
• a storage capacity of the second region is smaller than a storage capacity of the first region.

An information processing method for causing a computer to execute processing for:

• referring to a storage unit configured to store a control program for controlling an onboard apparatus, an inspection program for performing an operation check of the onboard apparatus or an onboard Electronic Control Unit (“ECU”) for controlling the onboard apparatus, and validity information indicating whether the inspection program is valid or invalid;
• executing the inspection program if the validity information indicates that the inspection program is valid;
• and
• executing the control program if the validity information indicates that the inspection program is invalid,
• wherein the storage unit stores a boot program that is executed when the onboard ECU is started,
• the storage unit includes a first region accessible by a control unit that is executing the control program, and a second region to which access by the control unit that is executing the control program is restricted,
• the validity information is stored in the second region,
• the control unit that is executing the boot program accesses the second region using a physical address,
• the control unit that is executing the control program writes log data of control or drive of the onboard apparatus, in the first region, and
• a storage capacity of the second region is smaller than a storage capacity of the first region.
