example 1

[0029] Example 1: Used for lane safety monitoring

[0030] Assume that a vehicle breaks down in the overtaking lane 5 kilometers ahead of the vehicle and occupies the driving lane. Then, the vehicle in front of the fault will upload the corresponding information to the cloud safety map processing platform. The cloud safety map processing platform can generate safety information about 5 kilometers ahead according to the uploaded information, and update the safety map data (compared to the previously existing safety map data, it can also create a new safety map data). combined reference Figure 4As shown, the content of the safety map data can include: types and conditions of safety incidents - Beijing-Shanghai Expressway heading for Beijing, a bicycle broke down 500 meters away from Kunshan Exit and occupied the traffic lane; active intervention area setting - active intervention area is set to a distance Within 50 meters of the accident site, the intervention action is spe...

[0031] Example 2: Hazardous Object Identification

[0032] Assume that in heavy rain, vehicles in many places on the road ahead of the vehicle lose control and skid, causing traffic accidents. Then, the vehicle in front of the accident place uploads the corresponding information to the cloud safety map processing platform. Based on the uploaded information, the cloud safety map processing platform can generate safety information about multiple accident locations ahead and update the safety map data. According to the updated safety map data, the vehicle's safety map processing module can identify the information of multiple accidents ahead, and can provide safety warnings. The content of the safety warning can be: heavy rain, please slow down or re-plan the route. Thus, the driver is reminded in advance to avoid unsafe road sections or take safe measures to pass through these road sections safely.

Abstract

A driving assistant system based on an advanced driver assistant system (ADAS) comprises a man-computer interaction module, a safety map processing module, a vehicle environment data acquisition module, a vehicle environment data processing module, a position module and a communication module, wherein the surrounding environment data collected by all sensors of the ADAS are obtained through the vehicle environment data acquisition module and sent to a cloud safety map processing platform through a network after an object and / or an event is recognized by the vehicle environment data processing module, so that safety map data are generated; the safety map processing module processes the safety map data, so that a safety alarm is generated; the safety alarm contains corresponding position information; and the man-computer interaction module is used for presenting the safety alarm. According to the driving assistant system based on the ADAS, the safety pre-warning range is greatly widened, and the driving safety is further improved.

Description

technical field [0001] The invention relates to safe driving assistance technology, in particular to an ADAS-based driving assistance system. Background technique [0002] At present, with the gradual popularization of the use of automobiles, automobiles have become an indispensable means of transportation in people's daily life. Safe driving has also become an issue of increasing concern. For this reason, advanced driver assistance systems (ADAS, Advance Driver Assistant System) are installed on many cars to enhance the safe driving of users during driving. ADAS uses a variety of sensors installed on the car to collect environmental data inside and outside the car, and perform technical processing such as identification, detection and tracking of static or dynamic objects, so that the driver can be aware of it in the fastest time Potential hazards to draw attention to and improve safety. The sensors used in ADAS mainly include cameras, radars, lasers and ultrasonics, etc...
