CN-113492874-B - Device and method for warning about vehicle driving

Abstract

The present invention relates to an apparatus and method for alerting about vehicle driving. The means for providing a warning about the driving of the vehicle comprise sensors which obtain the status of the driver and the status of the vehicle. The input device receives risk criterion information from the driver, the risk criterion information including a critical speed defined based on a tendency of the driver and a holding time of the driving assistance function. The memory device stores at least one program instruction for execution by the controller. The controller sets at least one additional warning output condition based on the risk criterion information, determines whether the additional warning output condition is satisfied based on a state of the driver and a driving state of the vehicle, and outputs a driving warning based on a result of the determination.

Description

Device and method for warning about vehicle driving Cross Reference to Related Applications The present application claims priority from korean patent application No.10-2020-0041120, filed on 3 months 4 in 2020, the entire contents of which are incorporated herein by reference. Technical Field The present invention relates to an apparatus and method for providing warning about driving of a vehicle. Background In recent years, intelligent driver assistance systems have been developed to improve the convenience of the driver. The intelligent driver assistance system may perform a driving assistance function that assists a driver of the vehicle in driving while maintaining a lane or speed in consideration of a road in front of the vehicle and obstacles around the vehicle. Also, the intelligent driver support system may alert the driver that the driving assistance function is disabled when the driving assistance function cannot be performed. However, since the warning based on disabling the driving assistance function is intensively performed, the driver may not recognize the warning and may determine that the usability is lowered. Or the driver may feel danger due to lack of warning. Therefore, a technique capable of outputting a warning based on the tendency of the driver even when the driving assistance function is disabled is demanded.

The controller may be configured to receive risk criterion information input from the driver when the controller determines to deactivate the driving assistance function based on the state of the vehicle obtained from the sensor. The controller may be configured to adjust the additional alert output time based on the threshold speed and the hold time. In addition, the controller may be configured to set an additional warning output condition that the driver is in the hand-off state, no warning according to the hand-off state is output, the speed of the vehicle exceeds the critical speed, the holding time of the driving assistance function exceeds the holding time input from the driver. The sensor may be configured to obtain the state of the driver by sensing a state in which the driver does not grasp the hand away of the steering wheel. The sensor may be configured to obtain a state of the vehicle by sensing a speed of the vehicle. The controller may be configured to output the additional warning through the output device at an output time adjusted based on the critical speed and the holding time when the condition for outputting the additional warning is satisfied based on the state of the driver and the state of the vehicle. Further, the controller may be configured to output, by the output device, a warning based on the disabling of the driving assistance function when the condition for outputting the additional warning is not satisfied, based on the state of the driver and the state of the vehicle. The output means may be configured to output an alarm based on the disabling of the driving assistance function through an image representing the alarm, and to output an additional alarm through a visual pop-up function and an audible function. The driving assistance function may include a lane keeping function. According to another aspect of the present invention, a method for warning about driving of a vehicle may include obtaining a state of a driver and a driving state of the vehicle, receiving risk criterion information from the driver, the risk criterion information including a critical speed defined based on a tendency of the driver and a holding time of a driv
