s401, acquiring the running data of the target vehicle, and identifying whether the target vehicle has abnormal running according to the running data.
It should be noted that, in the running process of the vehicle, the running data of the vehicle uploaded by the bus may be acquired through the vehicle-mounted T-BOX, and the fault diagnosis may be performed on the target vehicle according to the acquired running data of the vehicle, so as to identify whether the target vehicle has a running abnormality.
Alternatively, a fault diagnosis result of the target vehicle may be received, and whether or not the target vehicle has a driving abnormality may be identified based on the received fault diagnosis result.
S402, if the target vehicle has abnormal running, determining that the target vehicle has a collision risk.
Optionally, if the fault diagnosis result of the target vehicle is recognized to be that the driving abnormity exists, determining that the target vehicle has a collision risk; and if the fault diagnosis result of the target vehicle is identified to be that no driving abnormity exists, determining that the target vehicle does not have collision risk.

On the basis of the above embodiment, the following describes a process of sending a deceleration reminding message to a rear vehicle.
As a possible implementation manner, on the basis of the above embodiment, after the step S102 is completed, the deceleration reminding message may be sent to the rear vehicle.
Optionally, after controlling the elastic anti-collision component of the target vehicle to be turned on, it is indicated that a collision may occur between the target vehicle and a rear vehicle belonging to the same vehicle fleet and located behind the target vehicle, and at this time, a deceleration reminding message may be sent to the rear vehicle.
The sending mode of the abnormal reminding can be set according to the actual situation.
For example, the abnormal alert may be information including a voice alert, a text alert, an APP (Application) notification, and the like, for example, the vehicle may be equipped with an alarm to send an alarm sound, or the vehicle-mounted display screen of the vehicle displays alert text, or the APP installed on the mobile phone of the rear vehicle driver is sent notification information in a wireless communication manner to alert the rear vehicle driver to decelerate.
