Abstract
The present invention discloses a safe driving early warning system for intervention based on driver emotions. The system obtains current driver facial expression dynamics through a driver emotion real-time recognition unit, performs intelligent emotional analysis based on the obtained facial expression dynamics, and controls a vehicle running status based on a real-time emotion recognition result. The system monitors driver emotions in real time during driving, and controls a vehicle driving status and/or issues a safety warning to a driver according to a monitoring result, so as to ensure the traffic safety of various vehicles from the perspective of the driver.
Claims10
A safe driving early warning system for intervention based on driver emotions, comprising:
- a driver emotion real-time recognition unit, configured to obtain current driver facial expression dynamics, and perform intelligent emotional analysis based on the obtained facial expression dynamics or transmit the obtained facial expression dynamics to a vehicle-mounted gateway unit for intelligent emotional analysis;
- wherein the driver emotion real-time recognition unit can be directly associated with a vehicle control unit according to a real-time emotion recognition result or can be associated with the vehicle control unit through the vehicle-mounted gateway unit, to control a vehicle running status;
- the vehicle-mounted gateway unit, respectively associated with the driver emotion real-time recognition unit, the vehicle control unit, a warning prompt unit, and a remote management unit;
- wherein the vehicle-mounted gateway unit can further cooperate with the driver emotion real-time recognition unit to perform emotion recognition;
- the vehicle control unit, linked to a speed control system and a braking system of the vehicle and associated with the vehicle-mounted gateway unit and the driver emotion real-time recognition unit, wherein the vehicle control unit controls the vehicle driving status according to a driver real-time emotional status analysis result sent by the driver emotion real-time recognition unit or the vehicle-mounted gateway unit;
- the warning prompt unit, respectively connected and cooperating with the driver emotion real-time recognition unit and the vehicle-mounted gateway unit;
- and
- the remote management unit, wherein the remote management unit cooperates with the driver emotion real-time recognition unit to complete driver emotion recognition through the vehicle control unit, and can give corresponding vehicle management and driver management control instructions and feed back the instructions to the vehicle-mounted gateway unit,
- wherein the driver emotion real-time recognition unit comprises a facial high-speed camera module and an emotion intelligent analysis and recognition module;
- the facial high-speed camera module is configured to capture the current driver facial expression dynamics;
- and
- the emotion intelligent analysis and recognition module is configured to perform intelligent analysis and recognition on the facial expression dynamics captured by the facial high-speed camera module, and determine a current driver real-time emotional status;
- wherein the driver emotion real-time recognition unit is directly associated with the vehicle control unit or indirectly associated with the vehicle control unit and/or the remote management unit through a vehicle-mounted gateway.
