Above-mentioned current radar information can be the automobile body of vehicle and the interval information of surrounding barrier, and current radar information is gathered to the distance sensor of the equipment accessible external connection or internal integration of collapsing.
The current vehicle distance information may be information on a distance between the vehicle and a surrounding obstacle or other vehicles, and the crush control apparatus may also recognize a surrounding environment of the vehicle through an Advanced Driving Assistance System (ADAS) installed in the vehicle to acquire current image information and current radar information.

Step S203: and judging whether the current driving information meets the collision condition or not according to the safety braking distance.
The collision condition may be a condition in which the vehicle is involved in a collision when safety braking is performed, and for example, the collision condition may be a safety distance threshold between the vehicle and the preceding vehicle. The collapse control device can acquire the following distance between the current vehicle and the surrounding vehicles through an externally connected or internally integrated sensor, and determines the collision condition according to the following distance.
It should be understood that, in order to determine whether a collision risk exists in a vehicle at present, in this embodiment, the crumple control device acquires a vehicle following distance through a sensor, determines a collision condition according to the vehicle following distance, and compares the safe braking distance with the vehicle following distance to determine whether the current driving information meets the collision condition, and if the safe braking distance exceeds the vehicle following distance, it is determined that the collision risk exists, that is, the current driving information meets the collision condition; and if the safe braking distance does not exceed the distance between the vehicles, judging that no collision risk exists, namely the current driving information does not meet the collision condition.
In this embodiment, the current vehicle speed is determined according to the current driving information, the safety braking distance is determined according to the current vehicle speed, and whether the current driving information meets the collision condition is determined according to the safety braking distance. According to the invention, the safe braking distance of the vehicle is determined according to the current vehicle speed, and then whether the current driving information meets the collision condition is judged according to the safe braking distance, so that whether the vehicle has collision risk is accurately and timely determined, the safety performance of the vehicle is improved, and the safety of a driver is ensured.
