Are the consequences of a broken accelerator pedal serious?
Compared with a broken brake pedal, the consequences of a broken accelerator pedal can be said to be much “safer” – basically it just prevents you from stepping on the accelerator and the car slowly stops.
But there is one situation that is extremely dangerous, that is, if the broken accelerator pedal gets stuck under the brake pedal, preventing you from depressing the brake, it may cause a serious accident on the highway.
So, if you unfortunately encounter such an incident, please be calm and steady, keep your steering wheel steady, make sure that the broken pedal is not under the brake pedal, then slowly apply the brakes and park the car. Double jump, place the warning triangle and wait for rescue – remember to take out the broken pedal after stopping.
Why does the accelerator pedal break?
Many people have already mentioned this issue. In fact, the accelerator pedal was originally designed to break under certain circumstances.
The electronic accelerator pedal of a passenger car breaks mainly to protect the driver’s legs in a collision. When an active or passive collision occurs, if the driver’s feet are still on the accelerator pedal, a huge The impact force will be transmitted to the lower legs through the accelerator pedal, causing personal injury. If the accelerator pedal breaks after a collision, force transmission will be avoided and the driver’s legs will be protected.
The breaking position is generally designed through a specific structure to ensure that it can break in an emergency. If you look closely, you’ll notice that the accelerator pedal’s connecting rod is made of plastic rather than metal.
Of course, this pedal should also have a certain strength to ensure that it will not be broken during normal use. According to the data provided by the Autohome article, the national industry recommendation standard “QC/T977-2014” recommends the strength of the automotive electronic accelerator pedal as follows:
1. Apply 550 N+/ in the positive direction of the pedal -10 N force, the pedal should be free of breakage and damage
2. Apply a force of 200 N+/-10 N in the opposite direction of the pedal, and the pedal should be free of breakage and damage
3 . Apply a force of 200 N +/-10 N in the vertical direction of the pedal rotation surface. The pedal should be free of breakage and damage.
It can be seen that if a relatively small force is applied in the opposite direction, the pedal may break. of.
