Embodiment approach 1

[0030] ***Description of structure***

[0031] figure 1 An example of the hardware configuration of the control device 200 and elements located around the control device 200 according to Embodiment 1 is shown.

[0032] The control device 200 is a computer mounted on the vehicle 100 to be driven by automatic driving. The control device 200 corresponds to a vehicle-mounted device. In addition, the operations performed by the control device 200 correspond to an information processing method.

[0033] The control device 200 is mounted on an ADAS-ECU (Advanced Driver Assistance System-Electronic Control Unit) 101 .

[0034] ADAS-ECU101 realizes automatic driving.

[0035] The control device 200 is multiplied in order to ensure safety against failure during automatic driving.

[0036] The control device 200 includes a processor 300 , a storage device 301 , and an input / output device 302 connected via a bus.

[0037] All control devices 200 have the same hardware configuration....

Embodiment approach 2

[0129]In Embodiment 1 above, the failure handling method updating unit 404 can extract failure handling influence changes using the map information, traffic information, and weather information obtained from the dynamic map 600, and determine whether to update the handling method. However, the information provided by the dynamic map 600 is huge, and processing of the information provided by the dynamic map 600 is expected to take a long time depending on the hardware performance of the control device 200 mounted on the vehicle 100 . Therefore, sometimes it is not effective to extract fault responses from the dynamic map 600 to affect changes.

[0130] In this embodiment, an example in which the failure response method update unit 404 acquires failure response influence change information showing a change in failure response influence from the dynamic map 600 will be described.

[0131] Differences from Embodiment 1 will be described below.

[0132] Matters not described below...

Abstract

A storage device (301) stores a failure handling table (405) that describes methods for handing failures occurring in devices mounted in a vehicle (100). A failure handling method update unit (404) updates the failure handling methods described in the failure handling table (405), in accordance with changes in the traveling environment of the vehicle (100).

Description

technical field [0001] The present invention relates to control when a failure occurs in equipment mounted on a vehicle. Background technique [0002] In the electronic control device of the advanced driving support system represented by the automatic driving system that requires high safety, the system is multiplied so that even if a malfunction occurs in the equipment mounted on the vehicle, the control will not be lost. By multiplexing the systems, even if one system fails, it is possible to continue processing with the fallback function through the remaining normal systems. In such an advanced driving support system, when a failure occurs in a vehicle-mounted device, it is important to select a countermeasure (stop on the shoulder, continue driving, let the driver take over, etc.) and execute it. It is especially important to choose the best response method to ensure the safety of users. [0003] Patent Document 1 discloses the following technology: when the advanced d...
