Abstract: Updating of a program is realized even with a small-sized temporary storage area. A program update system distributes an update program from an update program distributing unit to a vehicle control device. The update program distributing unit encrypts an update program by a predetermined unit of encryption, and transmits the update program, which has been encrypted, by a predetermined unit of transfer to the vehicle control device to be updated, the vehicle control device decrypts the received update program by the unit of encryption, and stores the update program, which has been decrypted, by a predetermined unit of writing in a program storage unit, and the unit of writing is an integral multiple of the unit of encryption.

Abstract: To provide an airflow amount measuring device capable of accurately measuring a flow amount of air without occurrence of warpage in a thin film portion when an airflow measuring element is mounted on a lead frame to form a resin-sealed package in which the airflow amount measuring element and the lead frame are sealed. A chip package includes a lead frame, an element mounted on the lead frame and having a detection portion, and a structure for sealing the lead frame and the element such that at least the detection portion is exposed. Then, the curvature radius ρ of the exposed portion of the element exposed from the sealing resin member is 2.13 or less.

Abstract: An electronic control device that is mounted on a vehicle and performs automated driving control using map information includes: a storage unit that stores basic map data; a communication unit that communicates with a data center to acquire map data managed by the data center as external map data; and a processing unit that determines a control mode of the automated driving control according to the acquired external map data and performs the automated driving control based on the determined control mode, position information of the vehicle, the basic map data, and the external map data.
With the configuration, availability of map information is secured and continuity of an automated driving function is improved even in a case where a communication situation is not good while a required storage capacity is suppressed by limiting the map information stored in the vehicle.-

Abstract: In an engine including an auxiliary chamber having an ignition plug therein, an amount of heat generated in the auxiliary chamber tends to be large, and thus it is necessary to suppress abnormal combustion. However, when a sensor is added to the ignition plug, a manufacturing cost of the ignition plug tends to increase. An ECU 2 includes an auxiliary chamber temperature estimation unit 21 that estimates a temperature of the auxiliary chamber 42, and an ignition control unit 22 that delays an ignition timing at a first decrease degree defined in accordance with a change amount of the ignition timing with respect to the temperature of the auxiliary combustion chamber as the temperature of the auxiliary chamber 42 increases in a case where the estimated temperature of the auxiliary chamber 42 is included in a middle temperature region equal to or lower than a first set temperature.
