Compared with the brake pedal fracture, the consequence of the accelerator pedal fracture can be said to be "safe", because the vehicle can not refuel, through the inertia car will slowly stop. But there may also be another situation, that is, if the broken accelerator pedal gets stuck under the brake pedal, making it impossible for you to hit the brake, the vehicle may cause a major accident at high speed.

Recently, there was an incident in the United States, Tesla Model X accelerator pedal broke. It is understood that at that time, the owner was driving normally on the way home, and when he passed a red street light, he stopped because it was a red light, and then he stepped on the accelerator, only to find that the vehicle had lost its power. fortunately, the traffic on the road was not there at that time, and the owner slipped the vehicle slowly aside, like stepping on the throttle again but found that the throttle pedal had broken and fell off.

Then the owner clarified, "I wanted to step on the gas, only to find that the pedal was gone." It should be pointed out that although his 2017 Model XP100D was equipped with an ejection start mode, he didn't use it very often and didn't turn it on at the time.

In fact, this is not the first case of Tesla. Texas modelS owners posted photos on the forum in 2017. Similarly, the accelerator pedal broke while driving. In June 2018, the hostess complained that the pedals of the vehicle had been broken, causing a traffic accident. From the video and pictures, it is not difficult to see that this is a Tesla model.

As can be seen from these cases, the accelerator pedal is broken at the same point on the plastic rod. Although most people have never heard of this defect, there is no doubt that it is not an isolated incident.

Broken pedal is not Tesla's patent, it was first revealed that a media friend test-driven Chery Erize 5 kicked the accelerator pedal, the incident caused an uproar in the industry.

In addition, plastic throttle electric pedals are also used in many luxury cars, but fracture accidents are relatively rare. For safety reasons, car owners have complained to the National Highway Safety Administration (NHTSA), but so far there is no exact record of the problem.

Why is the accelerator pedal broken? In fact, the throttle pedal is designed to be broken under certain circumstances. The fracture of the electronic throttle pedal of the passenger car is mainly due to the protection of the driver's leg in the collision. When the active or passive collision occurs, if the driver's foot is still on the throttle pedal, the huge impact force will be transferred to the calf through the throttle pedal, causing personal injury.

If the accelerator pedal breaks after the collision, the transmission of force will be avoided and the driver's leg will be protected. The location of this fracture is generally through a specific structural design to ensure that it can be broken in case of emergency. If you look closely, you can see that the connecting rod of the throttle pedal is plastic instead of metal.
