1. An apparatus for recording vehicular data, comprising:
- a first memory device which temporarily stores vehicular data, wherein the vehicular data includes at least operating data of an actuator and/or detecting data of a sensor;
a second memory device which has control data area for storing control data in nonvolatile manner, wherein the control data is data used to control a vehicle; and
a controller which records the vehicular data stored in the first memory device into the control data area of the second memory device by overwriting the control data in response to vehicular accident.

Abstract
An apparatus includes a first memory device, a second memory device and a controller. The first memory device stores vehicular data in accident. The second memory device has control data area for storing control data in nonvolatile manner. The controller records the vehicular data stored in the first memory device into the control data area of the second memory device by overwriting the control data in response to vehicular accident. It is possible to increase a recordable amount of vehicular data in vehicular accident without increasing recording capacity exclusively preserved to vehicular data.
