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 of the third processor are configured to perform communication between the second processor and the third processor.

Claims

1. A vehicle control system comprising:

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 a communication function processed on the real-time OS of the first processor and a communication function processed on the real-time OS of 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 processed on the multimedia OS of the third processor are configured to perform communication between the second processor and the third processor, in order to prevent the first vehicle control unit from being influenced by a failure occurring in the second vehicle control unit.

2. The vehicle control system according to claim 1, further comprising a third vehicle control unit configured to include a fourth processor installed with a multimedia OS, wherein the third processor and the fourth processor are configured to perform communication between the second vehicle control unit and the third vehicle control unit.

3. The vehicle control system according to claim 1, wherein the third processor is configured to access an external communication device.

4. The vehicle control system according to claim 2, wherein the fourth processor is configured to access an external communication device.

5. The vehicle control system according to claim 2, wherein the third vehicle control unit further includes a fifth processor installed with a multimedia OS, and wherein a communication function of the fourth processor and a communication function of the fifth processor are configured to perform communication between the fourth processor and the fifth processor, and the fifth processor is configured to access an external communication device.

6. The vehicle control system according to claim 1, wherein the second processor is formed of a processor-core in a multiple-core processor, and the third processor is formed of a processor-core in the multiple-core processor.

7. The vehicle control system according to claim 5, wherein the fourth processor is formed of a processor-core in a multiple-core processor, and the fifth processor is formed of a processor-core in the multiple-core processor.
