Automobile fire early warning method

Abstract

The invention provides an automobile fire early warning method, and belongs to the technical field of automobiles. The problem that in the prior art, early warning is not carried out on a vehicle fire disaster in a power-off state is solved. The automobile fire early warning method comprises the steps of: temperature information of a passenger compartment, colleting a cabin and a battery pack in an automobile at a preset first time interval; when the acquired temperature is greater than or equal to a temperature threshold value I, activating acquisition of the carbon monoxide concentration in the vehicle, otherwise, returning to the temperature acquisition step; when the collected carbon monoxide concentration is larger than or equal to the carbon monoxide concentration threshold value or the collected temperature is larger than or equal to the second temperature threshold value, controlling a low-voltage circuit of the whole vehicle to be powered on, sending a corresponding control instruction out to an execution unit, and executing vehicle door unlocking, vehicle window descending, tire pressure relief and sound-light alarm operation through the execution unit; otherwise, returning to the temperature acquisition step when the temperature is continuously smaller than the first temperature threshold value. According to the invention, fire early warning can be realized when the vehicle is parked and flames out, and the safety of the vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to an automobile fire early warning method. Background technique [0002] With the increasing importance of automobiles in people's lives, and the rapid development of automobile intelligence, the circuits of vehicles are more complex, with more electrical components, higher voltage and current, which lead to an increase in the risk of vehicle fires trend. [0003] At present, in automobile fire incidents, the proportion of fires occurring when the vehicle is parked and turned off without electricity is relatively high, especially for electric vehicles, most of the fires occur in the parking or charging state, and because the vehicle is basically parked when charging At the location of the garage or the charging station, the spread of fire in the event of a large area, so the loss is huge. [0004] In view of the above existing problems, the current existing technical patents are...

Problems solved by technology

However, this invention is applied in the process of vehicle driving, and it is an early warning to the driver. In the unpowered state, such as when the power is turned off after parking, the fire safety early warning effect cannot be achieved.
