Embodiment Construction

[0069] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0070] Such as figure 1 Shown is the location map of the road water vehicle online monitoring and driving assistance system on the car. The present invention provides a vehicle-mounted online monitoring and driving assistance system for road water accumulation, which is divided into four parts:

[0071] 1. Input module:

[0072] Including camera one 1, camera two 2, ultrasonic radar 4, vehicle body inclination sensor 5, auxiliary wading button 11.

[0073] The two cameras 1 and 2 are used to collect images of the road ahead. In order to avoid adverse environments such as rain and water from affecting the reliability of the camera, and to provide a better field of view for the camera, the cameras 1 and 2 are placed inside the windshield On the back of the interior rearview ...

Abstract

The invention relates to the field of automobile wading driving safety, and discloses a road ponding vehicle-mounted online monitoring and driving assistance system which comprises input modules, namely two cameras, a vehicle body tilt angle sensor, an ultrasonic radar and an auxiliary wading key, and output modules, namely a laser transmitter, a loudspeaker, a display screen and vehicle control equipment, the processing module is a control unit, and the energy module is a power supply. The invention further discloses a control method of the system. The method comprises the following steps: 1, acquiring required information including a road condition image, an automobile pitch angle and water depth of a position where an automobile is located; 2, processing information and calculating to obtain the water depth of the road surface at the laser point; and 3, according to the water depth information, judging and providing a suggested vehicle speed and a suggested gear, broadcasting a wading driving safety warning sound to a driver by a loudspeaker, providing driving suggestion prompt information to the driver by a display screen, or assisting the driver in controlling the vehicle to slowly run at a constant speed to pass through a waterlogged road surface by the vehicle control equipment, and the driving safety on the waterlogged road surface is improved.

Description

technical field [0001] The invention relates to the safety field of automobile wading driving, in particular to a vehicle-mounted online monitoring and driving assistance system and method for road water accumulation. Background technique [0002] The safety of automobiles in waterlogged roads has always been one of the focuses of people's attention to automobiles. Waterlogged roads mostly occur on low-lying roads in rainy weather, and sometimes in areas with rivers and lakes nearby. When a car falls into water, for the driving of the vehicle, if the speed is too high, hydroplaning will occur and the car will become unstable; for pedestrians on the road, it will also cause social morality problems because the tires splash water on the pedestrians on the side of the road. When the depth of the accumulated water is large, the car may even cause the accumulated water to enter the engine exhaust pipe, causing the engine to stall. If water enters the cylinder, it will directly ...
