Vehicle warning method

Abstract

The embodiment of the invention provides a warning method for a vehicle. The warning method comprises the following steps: establishing signal connection of a warning device, a vehicle control unit and a vehicle-mounted positioning device; acquiring a vehicle state, and judging the starting time of the warning device; obtaining the current position of the vehicle and the route of the running road,and planning the warning position and / or the warning route of the warning device; and enabling the warning device to execute a warning function according to the set time, position or route. By the adoption of the method, vehicles coming later can be reminded more intelligently and remarkably.

Description

technical field [0001] The invention belongs to the field of general vehicle signals, and in particular relates to a vehicle warning method. Background technique [0002] When the vehicle breaks down or has an accident, the driver of the vehicle needs to place a tripod behind the vehicle to warn other vehicles. However, the driver is prone to danger when placing the tripod. This danger generally comes from the impact of unconscious vehicles in the rear (because the rear vehicle cannot know in advance that the vehicle in front has an accident, so it cannot be avoided in time), resulting in road accidents. secondary accident. [0003] In order to solve this problem, there have been some designs in the prior art that place warning triangles on remote-controlled mobile cars, such as Beijing Institute of Technology's intelligent warning triangles for vehicles based on mobile terminal interaction (see patent document CN106218500A), The triangle warning device of Daimler AG (refe...

Problems solved by technology

[0004] The above designs can avoid the potential safety hazards caused by the artificial placement of the tripod, but the mobile car-mounted warning triangle is large in size. If the car coming from behind does not evade or slow down in time, it will even increase the collision damage of the car coming from behind. ; and the launch type warning triangle has a limited range, which is far less than the distance stipulated by traffic regulations. If a larger launch speed is used in order to increase the range, the launch itself is dangerous, and the fired warning triangle needs to be It is designed as a structure that can be retracted / deployed, and it is difficult to ensure accurate deployment and stability when landing, which affects the warning effect
