求翻译：在发生中低速追尾碰撞时可对追尾车辆有部分阻挡保护功能,但在高速情况下就形同虚设,无法起到阻止后车钻入碰撞的作用。是什么意思？

Low-speed rear-end collision in the event of a rear-end vehicle partially blocking protection function, but in the high case would be empty, can not play a role in prevent car drill into collision.

In the case when low speed rear impact can be to catch up with the vehicle tail section block protection features, but in high-speed connection with the useless, unable to stop the drilling into the collision of the car.

The low speed follows the collision when the occurrence may to follow the vehicles to have the part to prevent the protection function, but exists in name only in the high speed situation, after is unable the impediment the vehicle to drill into the collision the function.

In low-speed rear impact on rear of vehicle when there is some barrier protection, but useless in high speed situations, not to block drilled into the car after collision.
