Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of active safety control method is present embodiments provided, applied to the active safety system of vehicle, the master of vehicle
Dynamic security system includes but is not limited to AEB (Autonomous Emergency Braking, automatic breaking system) and FCW
(Forward Collision Warning, frontal collisions early warning system) etc..Referring to Fig. 1, which can
With comprising steps of
S11: the driving status of the target vehicle of car load, the driving status of this vehicle and this front side road is obtained.
Car load is the total weight of current vehicle；The total amount of the weight of people, the weight of object and vehicle itself on vehicle
Constitute the total weight of current vehicle.The driving status of this vehicle includes but is not limited to this vehicle vehicle velocity V h and Ben Che acceleration A h.Mesh

Spacing time Th and collision time Tc.
Step S32 is consistent with step S22, and this embodiment is not repeated.
S33: it is added after spacing time Th is distinguished corresponding multiplied by weight with collision time Tc, obtains crashworthness
Tcrash。
Step S33 is consistent with step S23, and this embodiment is not repeated.
S34: according to car load, this vehicle travelling state and the alarm signal threshold value T pre-establishedFCWCorresponding relationship,
With the corresponding alarm signal threshold value T of the driving status of car load and Ben Che for obtaining with obtainingFCW。
The method for first passing through calibration in advance establishes car load, this vehicle travelling state and alarm signal threshold value TFCWCorresponding close
System, i.e. TFCW=f (O, Vh, Ah), wherein O indicates car load, and Vh indicates this vehicle speed, and Ah indicates this vehicle acceleration.Execute step
Rapid S34 matches to obtain alarm signal threshold value T corresponding with car load, this vehicle speed and this vehicle accelerationFCW。
S35: judge crashworthness TcrashWhether alarm signal threshold value T that matching obtain is greater thanFCW, if so, sending alarm signal
To entire car controller.
After entire car controller receives alarm signal, anti-collision warning before triggering FCW function is realized.In order to reduce erroneous judgement, also
Crashworthness T can be judged at least continuous two periodscrashThe alarm signal threshold value T obtained greater than matchingFCWAfterwards, report is retransmited
Signal is warned to entire car controller.
