30results about How to "Avoid dangerous driving" patented technology

The application provides a message pushing method, device and equipment. The method comprises the steps of: acquiring a notification message; acquiring a current scene of a vehicle; determining a message pushing mode corresponding to the current scene; and pushing the notification message to a receiving object in the message pushing mode, so that the acquired notification message can be combined with the current scene to be pushed to a user in a targeted mode. Therefore, the user can simply and effectively acquire the notification message in a corresponding driving scene and dangerous driving of the user is avoided, so that experience of the user is improved.

The invention discloses a method and system for assisting driving, belonging to the technical field of driving safety, which includes an input module: input driving state value warning range, driver's fingertip temperature x and the driver's grip force of the palm holding the steering wheel measured by the fingertip c; calculation module: read the steering wheel grip c and fingertip temperature x in the input module, and substitute them into the mathematical model established by the genetic programming method to calculate the driving state value y; logic judgment module: receive the calculation result of the calculation module, and judge the driving Whether the state value y is within the early warning range of the driving state value; if it is not within the early warning range of the driving state value, send control information; output module: receive the control information from the logic judgment module and send out a driving signal. The present invention adopts the measurement method with the infinite norm as the optimization target to obtain a measurement model of the driving safety fitness value related to the driver's palm temperature and grip strength, and obtains an optimal estimated value through the calculation of the measurement model, the value These two abilities of the driver can be reflected in real time, and then the driving state can be monitored to avoid the occurrence of dangerous driving states.

The invention discloses a device and method for fatigue driving early warning of a driver of a truck. The device and the method are characterized in that the heart rate before driver driving is preliminarily detected through a first preset heart rate, so that the driver is warned to avoid dangerous driving when the heart rate of the driver is too low due to disease, fatigue driving and the like, the fatigue state of the driver is preliminarily determined through the rapid comparison of the initial heart rate and the first judgment heart rate, so that the method and the device are beneficial toimproving the detection accuracy. According to the method and the device, the first judgment face model is generated by combining the initial face information of the driver with the existing public face three-dimensional model, and then the first facial expression three-dimensional contrast library is generated by combining the existing fatigue driving expression library, so that the driver of different facial features can have the own individual facial expression three-dimensional contrast library, and the recognition accuracy of the fatigue state of the driver is improved.

The invention discloses an early warning system and method for a time pressure state of a driver. According to the early warning system for the time pressure state of the driver, a millimeter wave radar, a data collector, a heart rate sensor and other equipment are mounted on a vehicle to collect driving habit parameters of the driver and used for judging whether the driver is in the time pressurestate or not, and the early warning system for the time pressure state of the driver is formed. The early warning method for the time pressure state of the driver comprises the steps that the drivinghabit parameters are determined; a voice prompt threshold value and a time pressure state threshold value are set; whether the voice prompt is carried out or not is determined; and whether the driveris in the time pressure state or not is determined. According to the early warning system and method for the time pressure state of the driver, a driving state of the driver can be monitored and judged in real time, the voice prompt is given, and the driver is avoided to enter a dangerous driving state; and whether the driver is in the time pressure state or not is judged, a real-time operation mode is compared with a normal operation mode, and suitable auxiliary is given to achieve the purpose of safe driving.
