Example 1
As shown in fig. 1, a preceding vehicle starting and driving reminding method based on a preceding radar includes the following steps:
step one, setting a calibration distance;
step two, when the vehicle is in a stop state, if the distance between the vehicle and the front vehicle is detected to be unchanged for 2 seconds by the radar in front of the vehicle, entering a mode of continuously detecting a starting state of the front vehicle, and under the mode, when the radar in front of the vehicle detects that the distance between the vehicle and the front vehicle is increased by a calibration distance, judging that the front vehicle is started to run, and sending a reminding signal;
and step three, the vehicle instrument receives the reminding signal transmitted by the radar in front of the vehicle and sends out a reminding voice or a set reminding sound.
And setting the standard distance to be 10cm in the first step.
And in the second step, the vehicle is in a stop state, and the vehicle speed is less than 1 km/H.
And in the second step, the distance between the vehicle and the front vehicle detected by the front radar of the vehicle is the distance between the head of the vehicle and the tail of the front vehicle. Specifically, the distance between the position at the forefront of the head of the vehicle and the position at the rearmost of the rear of the front vehicle.
And in the second step, if the vehicle front radar detects that the distance between the vehicle and the front vehicle is not changed within 2 seconds, the vehicle front radar does not enter a mode of continuously detecting the starting state of the front vehicle.
And in the second step, in the mode of continuously detecting the starting state of the front vehicle, when the radar in front of the vehicle detects that the distance between the vehicle and the front vehicle is not increased to the calibrated distance, judging that the front vehicle does not start to run, and not sending out a reminding signal.
Example 2
A front radar-based front vehicle starting and running reminding method is mainly realized by the following two parts:
1. front radar
The distance reminding method is used for identifying the distance between the vehicle and the front vehicle, and the specific reminding distance is realized by calibration. For example, if the nominal distance is 10cm, when the vehicle is in a stopped state (the vehicle speed is less than 1km/H, the parameter can be changed), if the distance from the vehicle to the preceding vehicle is detected to be unchanged for 2 seconds, the vehicle enters a mode of continuously detecting the starting state of the preceding vehicle, and when the distance is increased by 10cm, the vehicle is judged to have started to run, and a reminding signal is sent.
2. Instrument and meter
After the instrument receives the reminding signal, the instrument sends out a reminding voice or a set reminding sound. The presentation mode is set in the meter.
Although the preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, the scope of the present invention is not limited to the specific details of the above embodiments, and any person skilled in the art can substitute or change the technical solution of the present invention and its inventive concept within the technical scope of the present invention, and these simple modifications belong to the scope of the present invention.
