The tank car rollover warning system and method based on slip rate and yaw force belong to the technical field of vehicle safety. The warning system includes a wheel speed sensor, a yaw rate sensor, a data storage module, a data processing module and an alarm device. The present invention proposes a rollover early warning system and method based on the inside wheel slip rate and the yaw force of the tank body without affecting the normal driving of the driver. The rollover threshold range is input into the data processing module, and through real-time data collection and calculation evaluation, the dangerous state of tanker rollover can be effectively predicted in advance, with better predictability and accuracy. The wheel speed sensor, the yaw rate sensor and the vehicle-mounted data processing module adopted in the present invention are small in size, low in cost, easy to install, and convenient to be popularized and popularized in dangerous goods transportation vehicles.
Description
technical field [0001] The invention belongs to the technical field of vehicle safety, in particular to a tank car rollover warning system and method based on slip rate and yaw force. Background technique [0002] Dangerous goods transport vehicles usually contain liquid hazardous chemicals in the tank, and the liquid in the tank swings during the turning process, which can easily cause the vehicle to become unstable, and in severe cases, directly cause the vehicle to roll over. The rollover of dangerous goods transport vehicles will not only cause casualties to drivers, passengers and other people on the road, but also the leakage of hazardous chemicals in tanks will have a huge impact on the environment and roads. Therefore, to prevent problems before they happen, it is very necessary to carry out effective early warning when the dangerous goods transport vehicle just produces a rollover tendency, and the accurate assessment of the rollover state of the vehicle is the prem...
