Problems solved by technology
In the existing radar activation scheme, when the radar fails, although the alarm can be given, other normal radars can still work normally. When the driver is driving, it is easy to ignore the alarm sound and mistakenly think that the radar is working normally, so that the car may collide. obstacles, causing safety accidents

Embodiment Construction
[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0036] Please refer to Figure 1-3 , in a specific embodiment, a kind of automobile radar start-up detection method provided by the present invention, the vehicle body controller is provided with the position identification of the radar that identifies each position, namely several radars are distributed in different parts of the vehicle body, each Each part has a corresponding position identification, including:
[0037] Step S1: The car key is turned to the ON position, the current radar is powered on, initialized, and self-diagnosed;
[0038] Step S2: The current radar waits to receive the loc...

The invention belongs to the technical field of automobile control and provides an automobile radar start detection method and system. The method includes the steps that a current radar device is powered on, initialized and self-diagnosed; till position identification sent by an automobile body controller is received, the position identification is stored, and self-diagnosis data are sent to the automobile body controller; the current radar device judges whether the self-diagnosis data are fault information or not; if the self-diagnosis data are the fault information, the current radar device stops supplying power to a rear radar device, and meanwhile the automobile body controller stops sending position identification corresponding to the rear radar device to the rear radar device; and the automobile body controller sends a radar fault signal to an instrument, the position identification of the current failing radar device is recorded, a buzzer is driven to give an alarm, and then all the radar devices are shut down. The method that all the radar devices are shut down if one radar device breaks down is adopted, a driver can be better reminded of the breakdown of one radar device, and the radar devices cannot work, so that unnecessary collisions of an automobile are prevented, and the safety of the whole automobile and passengers is improved.
Description
technical field [0001] The invention belongs to the technical field of automobile control, and in particular relates to a method and system for detecting the start of an automobile radar. Background technique [0002] Automotive radar is a reminder device that reminds the driver of the distance of obstacles while the car is running. If the car is close to the obstacle, the buzzer will sound an alarm; the closer the car is to the obstacle, the higher the frequency of the alarm. The existing radar startup scheme is: if there is a radar failure, when the radar is started, the buzzer in the radar driving instrument will beep twice; if there is no radar failure, when the radar is started, the buzzer in the driving instrument will beep once Beeps followed by normal operation of the radar without radar failure. In the existing radar activation scheme, when the radar fails, although the alarm can be given, other normal radars can still work normally. When the driver is driving, it...
