electronic control unit

Abstract

The radio data obtained via the radio equipment (91) stored in the buffer (5A) for the radio equipment control unit is moved by the radio data receiving unit (321) to the intermediate buffer (5M) for radio data. In addition, the in-vehicle data stored in the buffer (5B) for the in-vehicle communication control unit is moved from the in-vehicle data receiving unit (331) to the intermediate buffer (5N) for in-vehicle data. At this time, the radio data reception task is performed in priority over other processing such as the in-vehicle data reception task for transferring various data. That is, once the radio data received by the radio equipment control unit (22) is stored in the buffer area (5A) for the radio equipment control unit, it is sequentially moved to the intermediate buffer area (5M) for radio data, so that the radio equipment control can be suppressed. Possibility of internal buffer (5A) being filled with radio data.

Description

[0001] Cross-reference of related applications [0002] This disclosure is based on Japanese Application No. 2013-239171 filed on November 19, 2013, and the content of the description is incorporated herein. technical field [0003] The present disclosure relates to an electronic control device for a vehicle. Background technique [0004] In recent years, it has been proposed to implement each vehicle based on data (referred to as radio equipment data or radio data) from other vehicles or roadside equipment received by a radio equipment for implementing vehicle-to-vehicle communication and road-to-vehicle communication. An electronic control device that controls the process. Such an electronic control device is mainly composed of a known microcomputer including a CPU, RAM, ROM, etc., and programs (that is, application programs) corresponding to various control processes are stored in nonvolatile memories such as ROM. [0005] In addition to radio data, data indicating the ...

Problems solved by technology

[0016] In particular, since radio data is data received from a dynamically changing communication partner, there is no guarantee that the same data will be acquired again later, so it is required to avoid discarding the radio data as much as possible
