DTC C1805-81: LKAS CAN Signal Error: General Description

Autonomous Emergency Braking (AEB) is designed to avoid collision or reduce damages from an accident caused by delayed braking or insufficient braking power due to distraction of the driver.

System control process is as follows:

1. AEB uses a Radar sensor and LDWS (Lane Departure Warning System, LKAS (Lane Keeping Assist System)) uses a Camera sensor to detect vehicles ahead and data fusion.
2. AEB identifies the AEB controllable status using fusion detection data.
3. AEB calculates required deceleration speed depending on the speed/distance of vehicles ahead.
4. AEB transmits the calculated "Required Deceleration Speed' to Integrated Brake Actuation Unit (IBAU) through CAN (Controller Area Network) communication.
5. Integrated Brake Actuation Unit (IBAU) calculates a required torque to implement "Required Deceleration Speed", and then controls the brake control.
