Problems solved by technology

The current vehicle-mounted terminal can only obtain the vehicle's own information or information from the satellite positioning system. Through the application of electronic maps, it can only prompt qualitative information such as "slow down" and other information, but cannot quantitatively and comparatively control the speed. precise guidance

Embodiment Construction

[0033] The steering anti-rollover information of the vehicle to be acquired by the present invention includes two aspects, one is the information of the vehicle itself, and the other is the road information. Therefore, the supporting hardware facilities include the on-board unit for information acquisition and processing and radio frequency roadside equipment. The information of the vehicle itself is loaded through the on-board unit, and the road information is obtained through the roadside radio frequency device. The on-board unit is pre-installed on the car body and connected to the CAN network of the whole vehicle. It can not only obtain vehicle information, but also has the function of information and data processing. The radio frequency equipment on the roadside is installed next to the turning road, about 50-100 meters away from the turning point in front (such as figure 2 shown), obtain the road information, and broadcast it to the vehicle-mounted unit through the DSRC...

Abstract

The invention discloses a method for obtaining and processing vehicle swerving anti-overturn information, and the method is characterized in that radio frequency equipment on a roadside broadcasts road information; a vehicle-mounted unit installed in the vehicle obtains information broadcast by the radio frequency equipment; meanwhile, the vehicle-mounted unit obtains the self information of the vehicle and the real-speed information of the vehicle, and obtains a swerving speed limit by calculation; and the swerving speed limit is compared with real-time vehicle speed to give an alarm to a driver in real time. By utilizing the method, vehicle situation information and road information are combined and integrated to obtain a reasonable speed limiting upper limit by calculation, vehicle difference is considered, and road conditions are considered, thus the speed guidance for the driver is more accurate.

Description

technical field [0001] The invention relates to the acquisition and processing of vehicle safety information, in particular to an information acquisition and processing method for assisting vehicles in turning safely on turning roads, which is mainly applied to vehicles and roadsides. Background technique [0002] Rollover accidents are more likely to occur when vehicles are turning, and rollovers can easily cause casualties, especially rollovers of commercial passenger cars, commercial trucks, and semi-trailers, which often cause major safety accidents. Due to differences in geographical conditions, roads have different restrictions on the turning speed of vehicles. If you do not pay attention to the control of driving speed when turning, it is easy to cause the danger of rollover. [0003] Typically, steering speed is controlled empirically by the driver. When entering an unfamiliar road, because the driver is not familiar with the road information, if the speed of the ve...
