Abstract

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.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to an early warning system and method for a driver's time pressure state. Background technique [0002] Time pressure has become an important reason for dangerous driving behavior, especially professional drivers need to reach their destination within the specified time, which increases the incidence of traffic accidents. The vehicle motion parameters and the driver's physiological indicators can reflect the impact of time pressure on driving behavior in real time, and can be used as the basis for judging the driver's time pressure state. [0003] When the driver is under time pressure, the driver's perception of the environment, judgment of danger, and ability to control the vehicle all decline to varying degrees. Compared with the state of no time pressure, the acceleration of the vehicle and the distance between the vehicle and the vehicle in front will change significant...
