Abstract

Provided is an electronic control apparatus including a reconfigurable logic circuit. The electronic control apparatus includes an information collection unit which collects information and a processing determination unit which determines a combination of processing information to be executed by the logic circuit, from a processing information storage unit that stores a plurality of pieces of processing information, on the basis of the collected information. The logic circuit is reconfigured on the basis of the combination of processing information determined by the processing determination unit.

Claims (30)

1. An electronic control apparatus including a reconfigurable logic circuit, comprising:

an information collection unit which collects information; and

a processing determination unit which determines a combination of processing information to be executed by the logic circuit, from a processing information storage unit that stores a plurality of pieces of processing information, on a basis of the collected information,

wherein the logic circuit is reconfigured on a basis of the combination of processing information determined by the processing determination unit,

wherein the processing information storage unit stores a division number of a circuit region where the logic circuit is reconfigured, and

the processing determination unit divides the circuit region based on the division number and reconfigures the logic circuit in each divided circuit region.

2. The electronic control apparatus according to claim 1 , further comprising:

an operation mode storage unit which stores a correspondence between the collected information and an operation mode; and

a mode selection unit which selects the operation mode from the operation mode storage unit, on a basis of the collected information,

wherein the processing determination unit determines the combination of processing information to be executed by the logic circuit, on a basis of the operation mode selected by the mode selection unit.

3. The electronic control apparatus according to claim 1 ,

wherein the processing information storage unit stores the number of times of reconfiguring the logic circuit, and

the processing determination unit reconfigures the logic circuit on a basis of the number of times.

4. The electronic control apparatus according to claim 1 ,

wherein the processing information storage unit stores an order in which the logic circuit is reconfigured, and

the processing determination unit reconfigures the logic circuit on a basis of the order.

5. The electronic control apparatus according to claim 2 ,

wherein the information collection unit collects at least one of information regarding a travelling situation including expressway travelling, city travelling, or parking of an own vehicle, information regarding a weather situation including sunny, rainy, day, or night, and information regarding an emergency situation including an abnormality of the own vehicle.

6. The electronic control apparatus according to claim 5 ,

wherein the mode selection unit selects the operation mode according to at least one of the travelling situation including expressway travelling, city travelling, or parking of the own vehicle, the weather situation including sunny, rainy, day, or night, and the emergency situation including the abnormality of the own vehicle, on a basis of the information collected by the information collection unit.

7. An electronic control system, comprising:

the electronic control apparatus according to claim 1 ; and

a communication unit connected to a network,

wherein the electronic control apparatus updates the processing information to be stored by the processing information storage unit, on a basis of processing information collected from the communication unit.

8. An electronic control method, comprising:

causing an electronic control apparatus to collect information; and

causing the electronic control apparatus to determine a combination of processing information to be executed by a reconfigurable logic circuit, from a processing information storage unit that stores a plurality of pieces of processing information, on a basis of the collected information,

wherein the logic circuit is reconfigured on a basis of the determined combination of processing information,

wherein the processing information storage unit stores a division number of a circuit region where the logic circuit is reconfigured, and

the circuit region is divided based on the division number and the logic circuit is reconfigured in each divided circuit region.
