7. the control method of the security system of vehicle according to claim 6, which is characterized in that in the step S2,
If the data processing module thinks that the operation of footfeed is maloperation, the data processing module controls the brake module
Start the braking system of vehicle.
8. the control method of the security system of vehicle according to claim 5, which is characterized in that the security system is also wrapped
It includes: warning module；
In the step S2, if the data processing module thinks that the operation of footfeed is maloperation, the data processing
Module controls the warning module and issues warning signal to driver.
9. the control method of the security system of vehicle according to claim 5, which is characterized in that in step sl, if institute
It states barrier sensing module and detects that barrier, the barrier sensing module issue signal；
In step s 2, the information that the data processing module is transmitted according to the signal acquisition module carries out analysis and measurement and goes out vehicle
Maximum stopping distance, if maximum stopping distance beyond vehicle between front obstacle at a distance from when, and have footfeed behaviour
Make, the data processing module thinks that the operation of footfeed is maloperation.
10. the control method of the security system of vehicle according to claim 5, which is characterized in that in the step S1,
When vehicle start and parking, whether the barrier sensing module detection vehicle-surroundings have mobile barrier, if the barrier
Hinder object sensing module to detect the barrier for having mobile in vehicle-surroundings preset range, and have footfeed operation, in step S2
In, the data processing module thinks that the operation of footfeed is maloperation.
11. the control method of the security system of vehicle according to claim 5, which is characterized in that in step s 2, if institute
When stating data processing module and analyze car speed greater than safe speed, and having footfeed operation, the data processing module
The operation for thinking footfeed is maloperation.
12. a kind of vehicle, which is characterized in that the control of the security system including vehicle described in any one of claim 5-11
Method.
