Situation determines.Such as, predetermined threshold can be 0 degree, it is also possible to is 5 degree.
Step 304c, in the process of moving, continues to obtain the distance between barrier and vehicle, when this distance
During less than second distance, persistently export information.
Second distance can be set by system developer, it is also possible to is set by the user.When barrier and vehicle
Between distance less than second distance time, illustrate that this vehicle distances barrier is relatively near, continuously send out alarm.Make
Obtain user and know that the distance between vehicle and barrier is less by continuous print alarm song.
For example, when system developer can set second distance as 1 meter, when barrier and vehicle it
Between distance less than 1 meter time, continuously send out alarm.
Due to the distance between barrier and vehicle less than second distance time, the most only by conversion vehicle before
Enter direction and can not avoid the shock of vehicle base and barrier, now need to detect whether driver touches on the brake
Make vehicle deceleration or stopping, if driver does not takes measures, automatically control vehicle and carry out slowing down or stopping.
Concrete, whether the brake of detection vehicle is braked, if the brake of this vehicle is not braked, then
This brake operation is controlled by brake monitor.Here the brake said is the brake in vehicle, is to make
Vehicle deceleration, stop or keeping the dress that the device of halted state, brake monitor are control brake work
