Embodiment 1

[0045] An embodiment of the present invention provides a method for controlling vehicle early warning, see figure 1 , the method flow includes:

[0046] 101: Detect the motion state of the vehicle;

[0047] 102: If the state of the vehicle satisfies the preset early warning condition, confirm whether there is an obstacle in the target area according to the radar signal;

[0048] 103: If there is an obstacle in the target area, detect the movement state of the obstacle;

[0049] 104: According to the movement state of the obstacle, control the designated early warning equipment in the vehicle to send an early warning signal.

[0050] Wherein, in the embodiment of the present invention, the vehicle early warning system is used to control the implementation of the vehicle early warning method. Among them, the early warning system is composed of early warning controller and various input and output interfaces. The main control DSP (Digital Signal Process, digital signal process...

Embodiment 2

[0056] An embodiment of the present invention provides a method for controlling vehicle early warning, see figure 2 , the method flow includes:

[0057] 201: Detect the motion state of the vehicle.

[0058] Wherein, this step may be performed periodically after the vehicle is started.

[0059]The motion state of the vehicle can be determined by detecting the moving speed of the vehicle. Among them, the moving speed of the vehicle is determined from the received wheel speed pulse signal through the early warning system.

[0060] After detecting the moving speed of the vehicle, if the moving speed is greater than or equal to the preset speed, it is further detected whether the duration of the vehicle’s moving at a moving speed greater than the preset speed is greater than the preset time, when the above two conditions are met , it can be determined that the vehicle is in a normal driving state, and there is no need to enter the vehicle warning state, so the warning system ca...

Embodiment 3

[0090] An embodiment of the present invention provides a device for controlling vehicle early warning, see image 3 , the device consists of:

[0091] The first detection module 301 is used to detect the motion state of the vehicle;

[0092] A confirmation module 302, configured to confirm whether there is an obstacle in the target area according to the radar signal if the state of the vehicle meets the preset early warning condition;

[0093] The second detection module 303 is used to detect the movement state of the obstacle if there is an obstacle in the target area;

[0094] The first control module 304 is configured to control the designated early warning device in the vehicle to send out an early warning signal according to the movement state of the obstacle.

[0095] Wherein, the first detection module 301 is used for:

[0096] If it is detected that the vehicle is in a stationary state, it is determined that the state of the vehicle meets a preset pre-warning condit...

Abstract

The invention discloses a method and a device for controlling vehicle early warning, and belongs to the field of automobile control. The method comprises the following steps: detecting the motion state of a vehicle; if the state of the vehicle meets preset early warning conditions, determining whether an obstacle exists in an object region according to radar signals; if the obstacle exists in the object region, detecting the motion state of the obstacle; according to the motion state of the obstacle, controlling appointed early warning equipment in the vehicle to send out an early warning signal. Whether the obstacle exists in the object region is determined when the vehicle is detected to meet the preset early warning conditions, and the appointed early warning equipment in the vehicle is controlled to send out the early warning signal according to the motion state of the detected obstacle when the obstacle exists. A user in the vehicle can receive early warning information when the obstacle is close to the vehicle, so that an active early warning mode for the vehicle is realized, and the early warning efficiency of the vehicle is improved.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a method and device for controlling vehicle early warning. Background technique [0002] With the development of the automobile industry, more and more people have their own private cars. Due to the narrowness of urban roads and the concentration of people, it is easy to cause collision accidents with pedestrians or vehicles around the car when the vehicle is parked. [0003] In the prior art, in order to prevent the above-mentioned collision accidents after the vehicle is parked, after the vehicle is determined to be in a stationary state, the lights of the vehicle are controlled to flash or light up when the door is opened to remind pedestrians and other vehicles around to pay attention to safety. [0004] The inventor finds that the prior art has at least the following problems: [0005] The above-mentioned early warning method belongs to the passive early warning method. It c...
