Abstract
An apparatus and a method for detecting an abnormal ECU in a vehicle network are provided. The apparatus detects an abnormal ECU with high accuracy by storing status information of a vehicle and status information of the vehicle network, determining an activation maintenance time of the vehicle network based on status information of the vehicle and status information of the vehicle network, monitoring the vehicle network during the activation maintenance time of the vehicle network, and detecting an ECU that wakes up abnormally first in a plurality of ECUs as an abnormal ECU.
Claims14
An apparatus for detecting an abnormal ECU in a vehicle network, the apparatus comprising:
- storage configured to store status information of a vehicle and status information of the vehicle network, wherein the status information of the vehicle includes at least one piece of cumulative mileage information of the vehicle and state of charge (SOC) information of a battery provided in the vehicle;
- and
- a controller configured to
- determine an activation maintenance time of the vehicle network based on the status information of the vehicle and the status information of the vehicle network,
- monitor the vehicle network during the activation maintenance time of the vehicle network,
- detect an electronic control unit (ECU) that wakes up abnormally first in a plurality of ECUs as an abnormal ECU, and
- control the detected abnormal ECU based on an SOC of the battery.
A method of detecting an abnormal ECU in a vehicle network, the method comprising:
- storing, by a storage, status information of a vehicle and status information of the vehicle network, wherein the status information of the vehicle includes at least one piece of cumulative mileage information of the vehicle and state of charge (SOC) information of a battery provided in the vehicle;
- determining, by a controller, an activation maintenance time of the vehicle network based on the status information of the vehicle and the status information of the vehicle network;
- monitoring, by the controller, the vehicle network during the activation maintenance time of the vehicle network;
- detecting, by the controller, an electronic control unit (ECU) that wakes up abnormally first in a plurality of ECUs as an abnormal ECU;
- and
- controlling, by the controller, the detected abnormal ECU based on an SOC of the battery.
