Method, device, electronic device and medium for reminding driver during lane keeping

Abstract

The invention relates to a method, a device, an electronic device and a medium for reminding a driver during lane keeping. The method includes the following steps: detecting the parallel moment acting on the center of the steering wheel; if it is judged that the parallel moment is outside the range of the preset parallel moment, then detecting the vertical moment acting on the center of the steering wheel; if it is judged that the vertical moment is within the preset If it is judged that the parallel moment is within the preset parallel moment range, the temperature information on the steering wheel is detected; if it is judged that the temperature information is outside the preset temperature information range, the driver is reminded to take over the vehicle. This method can ensure that when the driver is normally supervising the vehicle, the lane keeping function will not generate false prompts due to its own sensors and judgment logic problems, avoid false alarms and false prompts to the greatest extent, improve functional reliability and user satisfaction, and at the same time Prevent the driver from using other objects to monitor the vehicle illegally and improve driving safety.

Description

technical field [0001] The present invention relates to the field of intelligent driving, in particular, to a method, device, electronic device and medium for reminding a driver in lane keeping. Background technique [0002] The lane keeping function belongs to the L2 level driving assistance function. The national law stipulates that when the L2 level driving assistance function is running, the driver cannot deviate from the driving behavior, and it is necessary to maintain the supervision of the operation of the vehicle driving function. In other words: the driver is in the lane keeping function. During operation, hands cannot be taken off the steering wheel. Therefore, the lane keeping function will monitor the steering torque on the steering wheel when the function is running, thereby ensuring that the driver does not deviate from the driving behavior when the function is running, in line with the requirements of relevant national laws and regulations. [0003] Since th...

Problems solved by technology

[0004] Assume that when the lane keeping function is running, the driver needs to provide a torque of 0.5-3N m, and the radius of the steering wheel is 0.2m. At this time, if the driver's hands are placed on the left and right sides of the steering wheel, when the force is 5N, it can generate about 5N ×0.2m=1N·m moment (0.2m is the horizontal distance between the point of action of the arm and the center of the steering wheel), which meets the requirements; if the driver’s hand is placed on the upper and lower sides of the steering wheel, and the acting force is 5N, the generated moment is only about 5N×0.05m=0.25N m (0.05m is the horizontal distance between the point of action of the arm and the center of the steering wheel), if the requirements are not met, the lane keeping function will remind the driver to take over the vehicle, causing false alarms and discomfort to the driver
