摘要： A software updating device is provided which executes a process for updating software used for operating vehicle-mounted equipment. The software updating device includes a controller that acquires the software and applies the software to the equipment in order to update the software. The controller is configured to: cause a warning device to output a warning when an abnormality relating to the equipment occurs. The controller is further configured to prohibit outputting of the warning by the warning device when the abnormality relating to the equipment is detected while the software update process is being executed.

摘要： Provided is a software updating device for executing processing for updating software causing an equipment mounted on a vehicle to operate. The software updating device includes a controller that acquires the software, and controls the equipment by applying the software to the equipment. The controller includes a first storage unit that stores acquired first software and a second storage unit that stores acquired second software. In a state where no driving force is output by a power train of the vehicle, the controller executes processing for updating the software by changing software to be applied to the equipment from the first software to the second software.

摘要： A software update device is configured to update software for an in-vehicle control device mounted in a vehicle. The software update device includes an information acquisition unit, an output unit, an execution unit, a communication status acquisition unit, a correction unit, and a notification unit. The information acquisition unit is configured to acquire, from a server provided outside the vehicle, update process information related to an update of the software. The output unit is configured to output consent request information for asking a user whether to consent to the update of the software. The execution unit is configured to execute an update process for the software according to response information that is a response to the consent request information from the user. The calculation unit is configured to calculate an estimate time required for the update. The communication status acquisition unit is configured to acquire communication status information related to a communication status with the server. The correction unit is configured to correct the estimated time based on the communication status information. The notification unit is configured to output information on the corrected estimated time. The notification unit is configured to, when the corrected estimated time is shorter than the estimated time before correction, not output information on the corrected estimated time.

摘要： An electronic control system for vehicles includes an electronic control device and a master device. The master device is connected to at least two or more groups of electronic control devices each including the electronic control device and gives an instruction to the electronic control device. The electronic control device includes a storage unit including a data storage side; a second detection unit that detects a state of a vehicle; a rewrite execution unit that writes update data acquired from the master device to the data storage side to rewrite a program; an activation determination unit that determines whether or not to activate the program rewritten with the update data; and an activation execution unit that activates the program. The master device includes an update data acquisition unit that acquires the update data from an external instrument; a first detection unit that detects the state of the vehicle, the first detection unit being different from the second detection unit; a rewrite instruction unit that instructs the rewrite execution unit to write the update data to the data storage side; and an activation instruction unit that instructs the activation execution unit to activate the program when determining that the vehicle is parked using the first detection unit after the rewrite execution unit writes the update data to the data storage side according to the instruction from the rewrite instruction unit. The activation determination unit determines whether or not the vehicle is parked using the second detection unit when the activation execution unit activates the program according to the instruction from the activation instruction unit. The activation execution unit activates the program when the activation determination unit determines that the vehicle is parked using the second detection unit. The activation determination unit determines whether or not the vehicle is parked using an index different from that for the activation instruction unit. Each of the first detection unit and the second detection unit acquires the state of the vehicle from a group of electronic control devices selected from the at least two or more groups of electronic control devices. The group of electronic control devices from which the first detection unit acquires the state of the vehicle is different from the group of electronic control devices from which the second detection unit acquires the state of the vehicle.
