Terminal device carried at vehicle, vehicle, prompting method of puddle pavement

Abstract

The embodiment of the invention, which relates to the technical field of the vehicle, provides a terminal device carried at vehicle, a vehicle, a prompting method of a puddle pavement, so that the potential safety hazard that a vehicle is trapped in or submerged in a puddle can be effective reduced or eliminated. The terminal device comprises: a storage unit, which is used for storing cartographic information and vehicle information of a vehicle itself; a sensor, which is arranged in front of the vehicle and is used for detecting a pavement condition of the vehicle driving path, particularly for detecting reflected wave information of the pavement ahead of the vehicle driving path, and sending the reflected wave information to a control unit; and the control unit, which is used for carrying out information processing including controlling of the storage unit and the sensor. The control unit determines whether a puddle exists at the pavement ahead according to the cartographic information, the vehicle information, and the pavement reflected wave information detected by the sensor and obtains maximum depth information of the puddle, thereby warning and reminding the driver. The provided terminal device can be applied to a vehicle.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a terminal device mounted on a vehicle, and a reminder method for the vehicle and puddle road surface. Background technique [0002] In recent years, there have been many traffic accidents caused by rainfall. When there is a lot of rainfall, rainwater will accumulate on the relatively low road surface, especially when there are potholes on the road surface, puddles will form at the potholes. There is a risk that vehicles that will pass through the side road will be trapped or submerged in the puddle, which may cause casualties. [0003] In the prior art, a path search technology based on vehicle width is disclosed to determine whether the width of each road is sufficient for vehicles to pass, but there is currently no technology that can solve the above-mentioned problem that vehicles may be trapped or submerged in puddles And the problem of risk.
