Embodiment 1

[0048] see figure 1 , is a flow chart of the vehicle radar warning display method provided by the first embodiment of the present invention, including steps:

[0049] Step S10, obtaining the vehicle condition information of the current vehicle, and obtaining obstacle information when the vehicle condition information meets the alarm condition;

[0050] Wherein, the vehicle condition information includes gear position information and vehicle speed information of the current vehicle, and the obstacle information is obtained by using a vehicle-mounted radar. Specifically, the front end and rear end of the current vehicle in this embodiment Each is equipped with four vehicle-mounted radars, which are used to perform distance detection and angle detection between the front end, rear end and obstacles of the current vehicle;

[0051] Step S20, determining an alarm area and an alarm level according to the obstacle information, and displaying an alarm screen on the vehicle display sc...

Embodiment 2

[0058] see image 3 , is a flow chart of the vehicle radar warning display method provided by the third embodiment of the present invention, including steps:

[0059] Step S11, acquiring the vehicle condition information of the current vehicle, and determining that the vehicle condition information does not satisfy the alarm condition when it is determined that the current vehicle is in the parking gear;

[0060] Wherein, when it is determined that the vehicle condition information does not meet the alarm condition, the display of the alarm screen and the voice alarm prompt are not performed;

[0061] Step S21, when the vehicle condition information satisfies the alarm condition, obtain obstacle information, and when it is judged that there are obstacles in front and behind the current vehicle, perform distance collection respectively to obtain the front-end distance and the rear-end distance;

[0062] Wherein, the front end distance is the distance value between the front en...

Abstract

The invention is suitable for the technical field of vehicles, and provides a vehicle-borne radar alarm display method and system, and a vehicle-borne terminal. The method comprises the following steps that: obtaining the vehicle condition information of a current vehicle, and when the vehicle condition information meets an alarm condition, obtaining obstacle information; according to the obstacleinformation, determining an alarm area and an alarm level, and according to the alarm area and the alarm level, carrying out alarm picture display on a vehicle-borne display screen; and according tothe alarm level, inquiring alarm frequency, and giving a voice alarm according to the alarm frequency. By use of the method, on the basis of the acquisition of the obstacle information, the alarm areaand the corresponding alarm level are accurately determined, the alarm picture can be correspondingly displayed according to the alarm area and the alarm level, and radar alarm accuracy is improved.In addition, through the query of the alarm frequency, alarm sounds of different frequencies are adopted to give a prompt alarm to users so as to perform a difference prompt effect by aiming at obstacles of different distances, and accuracy and the reliability of vehicle-borne radar alarm display can be improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a vehicle-mounted radar alarm display method, system and vehicle-mounted terminal. Background technique [0002] Radar is a transliteration of English Radar, originally meaning "radio detection and ranging", that is, using radio methods to find targets and determine their spatial positions. Therefore, radar is also called "radiolocation". An electronic device that uses electromagnetic waves to detect objects. Emit electromagnetic waves to irradiate the target and receive its echo, thereby obtaining the distance from the target to the electromagnetic wave emission point, the distance change rate (radial velocity), azimuth, height and other information. Radar can be used to detect aircraft, ships, missiles and other military targets. In addition to military purposes, radar can be used to navigate aircraft and ships in transportation, to study stars in astronomy, a...
