Vehicle-data recorder
First Claim
1. A vehicle-data recorder comprising:
- a steering-related-value sensor configured to detect a steering-related value representing one of;
(i) a state of a steering operation of a steering wheel of a vehicle, and (ii) a vehicle behavior caused by the steering operation;
a camera configured to capture object information relating to at least an object in an area surrounding the vehicle;
a first electronic control unit configured to record vehicle data into a memory in response to a recording condition being satisfied, the recording condition being satisfied when the detected steering-related value detected by the steering-related-value sensor is greater than or equal to a threshold value; and
a second electronic control unit connected to the camera, the second electronic control unit being configured to;
identify the object located in the area based on an image captured by the camera, and obtain a relative positional relationship between the identified object and the vehicle; and
in response to the obtained relative positional relationship being a specific relationship estimating that the steering operation is to be performed in a direction in which the vehicle avoids the object, change the threshold value of the recording condition to a smaller value than a value when the relative positional relationship is not the specific relationship.

Abstract
A vehicle-data recorder records vehicle data into a storage when a recording condition is satisfied. The recording condition includes a condition that a steering-related value representing a state of a steering operation performed by a driver or a vehicle behavior caused by the steering operation is greater than or equal to a threshold value. The vehicle-data recorder includes: an object-information obtainer that obtains object information relating to an object in an area; and a threshold-value changer that changes the threshold value to a smaller value when a relative positional relationship between an own vehicle and the object located in the area and identified based on the obtained object information is a specific relationship in which it is estimated that a steering operation is to be performed in a direction in which the own vehicle avoids the object, than when the relative positional relationship is not the specific relationship.

8. A vehicle-data recorder comprising:
-
a camera configured to capture object information relating to at least an object in an area surrounding a vehicle; and at least one electronic control unit connected to the camera, the at least one electronic control unit being configured to; identify the object located in the area based on an image captured by the camera, and obtain a relative positional relationship between the identified object and the vehicle; and record vehicle data into a memory in response to the relative positional relationship being a specific relationship estimating that a steering operation is to be performed in a direction in which the vehicle avoids the object.
