An automatic driving warning method, device and vehicle

Abstract

The invention discloses an automatic driving warning method, device and vehicle, which comprises the following steps: judging whether the automatic driving function is on, and if so, acquiring abnormal road condition information in front of the vehicle and driver's attention information in real time, wherein the driving The driver’s attention information is the effective time when the driver’s attention is not on the road ahead; judge whether the vehicle’s distance from the abnormal road ahead is greater than the distance threshold; if so, execute the corresponding The level of warning reminder; if not, the warning reminder will be executed directly. Through a combined warning strategy, the present invention can not only meet the requirements of high-level automatic driving in terms of functional safety, but also can truly and effectively remind the driver, so that the driver can clearly realize the actions that need to be taken at present, so as to Avoid hazards caused by high-level automatic driving functions.

Description

technical field [0001] The invention relates to the field of automatic driving safety, in particular to an automatic driving warning method, device and vehicle. Background technique [0002] With the rapid development of automatic driving technology, especially the application of L3 and L4 automatic driving technology, the human-computer interaction strategy is becoming more and more important. How to effectively warn the driver so that the driver will not be concerned about the automatic driving function The generation of trust is particularly important to avoid the occurrence of harm. Most of the current market only uses instrument panel display and vehicle sound reminders. For a high-level automatic driving function, it cannot effectively attract drivers and cannot meet high-level functional safety requirements. Therefore, a combined warning strategy is particularly important. [0003] With the improvement of the level of automatic driving function, the hands and feet of...

Problems solved by technology

Most of the current market only uses dashboard display and vehicle sound reminders. For a high-level automatic driving function, it cannot effectively attract drivers and cannot meet high-level functional safety requirements. Therefore, a combined warning strategy is particularly important.

[0003] With the improvement of the level of automatic driving function, the hands and feet of the driver are gradually liberated, and the driver does not need to control the steering wheel and the brake accelerator pedal. If there is no appropriate driver warning strategy, the driver will lose concentration and Excessive trust in functions, inability to take over the vehicle in an emergency, resulting in hazards. As we all know, the current update frequency of high-precision maps is too slow, and most of them are updated 4 to 6 times a year. The actual road conditions Construction areas often appear, and the frequency is much greater than 4 to 6 times a year. Road construction areas are often constructed by personnel and the blocking signs of temporary construction areas are not obvious. It is difficult for existing sensors of autonomous vehicles to detect construction signs and Doing avoidance will cause the vehicle to enter the construction area, hit the construction workers or conflict with the lane, so it is extremely important to avoid the road construction area when the automatic driving function is turned on

Most of the current warning strategies are relatively simple, only reminding from the instrument panel display and sound, which cannot meet the requirements of functional safety level ASIL C or ASIL D, and cannot really and effectively remind the driver to prevent the driver from misunderstanding, so new ones are urgently needed Technical solutions to solve current problems
