Embodiment 1

[0045] figure 1 This is the first embodiment of the vehicle control system of the present invention. The vehicle control system according to the first embodiment includes a control system ECU 100 as a control system electronic control device and an information system ECU 200 as an information system electronic control device. Both the control system ECU 100 and the information system ECU 200 are mounted on the vehicle and communicate with each other.

[0046] The control system ECU is an ECU that has a vehicle control function and controls the behavior of the vehicle such as starting / turning / stopping. Specific examples of the control system ECU include an engine ECU that controls the engine, a steering ECU that controls the steering operation, and a brake ECU that controls the braking operation. Control system ECU100 such as figure 1 As shown in (a), the processor core has a single-core processor 10 (hereinafter referred to as "core 10"), and a real-time operating system (h...

Embodiment 2

[0062] figure 2 This is the second embodiment of the vehicle control system of the present invention. The vehicle control system of the second embodiment also has a control system ECU 100 and an information system ECU 200 as in the first embodiment. Regarding the functions / configurations of the second embodiment, parts having the same functions / configurations as those of the first embodiment are denoted by the same reference numerals, and description thereof will be omitted or simplified. In the second embodiment, both control system ECU 100 and information system ECU 200 are mounted on a vehicle, and communicate with each other.

[0063] Information system ECU 200 of the second embodiment accesses a communication device outside the vehicle by connecting to communication network 52 outside the vehicle such as the Internet. Specific examples of communication devices outside the vehicle include personal computers, mobile terminals, other vehicle-mounted communication devices ...

Embodiment 3

[0069] image 3 This is the third embodiment of the vehicle control system of the present invention. The vehicle control system of the third embodiment includes a control system ECU 100 , an information system ECU 200 , and an information system ECU 300 . Regarding the functions / configurations of the third embodiment, parts having the same functions / configurations as those of the first and second embodiments are denoted by the same reference numerals, and description thereof will be omitted or simplified. In the third embodiment, control ECU 100 , information system ECU 200 , and information system ECU 300 are all mounted on a vehicle. Control system ECU 100 and information system ECU 200 communicate with each other, and information system ECU 200 and information system ECU 300 communicate with each other.

[0070] image 3 Communication between information system ECU 200 and information system ECU 300 having the configuration shown in (a) is performed by kernel 20d includi...

Abstract

A vehicle control system including: a first vehicle control unit configured to include a first vehicle control unit configured to include a first processor installed with a real-time OS; and a second vehicle control unit configured to include a second processor installed with a real-time OS and a third processor installed with a multimedia OS, wherein the first processor and the second processor are configured to perform communication between the first vehicle control unit and the second vehicle control unit, and a communication function of the second processor and a communication function ofthe third processor are configured to perform communication between the second processor and the third processor.

Description

technical field [0001] The present invention relates to a vehicle control system that communicates between a plurality of vehicle control devices. Background technique [0002] Conventionally, there is known a multiprocessor system that transmits and receives information among a plurality of processors (for example, refer to Patent Document 1). In this multiprocessor system, event information is transmitted and received between processors each equipped with a real-time OS (operating system). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2000-293499 [0004] However, in recent years, vehicles are becoming more value-added and functional by combining multimedia functions (information system) and vehicle control functions (control system). For example, developments have been made in which a curve in front is detected using map information of a navigation system equipped with a multimedia function, and a vehicle control system equipped with a vehicle control functi...
