Abstract
Disclosed are a vehicle control system and a driving method of a vehicle using the vehicle control system. The vehicle control system includes a processor that processes data related to driving of a vehicle, and a vehicle controller that controls the driving of the vehicle, wherein the processor analyzes characteristics of a risk section of a road corresponding to a signal received from a beacon installed in the risk section of the road, based on a sparse map including an installation position of the beacon, and characteristic information of the risk section.
Claims9
A vehicle control system comprising:
- a processor configured to process data related to driving of a vehicle;
- and
- a vehicle controller configured to control the driving of the vehicle,
- wherein the processor is configured to:
- receive a plurality of images captured by cameras of a plurality of vehicles while the plurality of vehicles travels along a road,
- identify road surface features associated with the road from the plurality of images,
- simplify line representations of the road surface features,
- identify a plurality of sections of a road based on the simplified line representations,
- generate a sparse map representing the plurality of sections,
- identify a risk section among the plurality of sections based on section information of each of the plurality of sections, the section information including at least one movement depiction of the vehicle and at least one road feature,
- analyze characteristics of the risk section of the road corresponding to a low-energy Bluetooth signal received from a communication with a beacon installed in the risk section of the road and classify the risk section into a high risk section and a low/medium risk section, based on the sparse map including an installation position of the beacon, and characteristic information of the risk section, wherein the high risk section includes an accident-prone section and the low/medium risk section includes an intersection section and a long term construction section,
- when the vehicle is approaching or arriving at the high risk section of the risk section, the processor is configured to control the vehicle controller to reduce a speed in a longitudinal direction of the vehicle to a predefined speed or lower,
- the processor is further configured to identify a target section corresponding to an area where a satellite signal is not received among the plurality of sections, based on the identification of the target section, the processor is further configured to control at least one operation of the vehicle, at least one operation including tunnel driving, window control operation and air cleaning function control.
A method for driving a vehicle using a vehicle control system, the method comprising:
- receiving a plurality of images captured by cameras of a plurality of vehicles while the plurality of vehicles travels along a road,
- identifying road surface features associated with the road from the plurality of images,
- simplifying line representations of the road surface features,
- identifying a plurality of sections of a road based on the simplified line representations,
- generating a sparse map representing the plurality of sections,
- identifying a risk section among the plurality of sections based on section information of each of the plurality of sections, the section information including at least one movement depiction of the vehicle and at least one road feature,
- analyzing characteristics of the risk section of the road corresponding to a low-energy Bluetooth signal received from a communication with a beacon installed in the risk section of the road and classifying the risk section into a high risk section and a low/medium risk section, based on the sparse map including an installation position of the beacon, and characteristic information of the risk section, wherein the high risk section includes an accident-prone section and the low/medium risk section includes an intersection section and a long term construction section;
- and
- when the vehicle is approaching or arriving at the high risk section of the risk section, reducing a speed in a longitudinal direction of the vehicle to a predefined speed or lower,
- the method further comprising identifying a target section corresponding to an area where a satellite signal is not received among the plurality of sections, based on the identification of the target section, and controlling at least one operation of the vehicle, at least one operation including tunnel driving, window control operation and air cleaning function control.
