AutoBeta(AutoBeta.net)09/16 Report--

Today, some netizens reflected to us that the Honda Accord hit a mobile roadblock and the hood bounced up when there was nothing wrong with the front of the car, requiring more than 10,000 maintenance fees. It is understood that this is the pedestrian protection device of Honda Accord.

The purpose of pedestrian protection device is to reduce the damage to pedestrians caused by collision as much as possible. The pressure sensor of the front bumper is used to detect whether a pedestrian collision accident occurs, and then a special lifting mechanism is used to lift the engine hatch cover a certain distance in a short time. When the pedestrian head or torso collides with the engine cabin cover, more buffer space can be obtained to avoid violent collision with the engine body with strong rigidity.

The starting point of the device is certainly good, but many users report that it is "too sensitive" to start pedestrian protection in the event of a slight collision, causing losses. For example, if you hit a chicken, cat or dog, the collision degree may not be serious and there is no obvious damage, but if the pedestrian protection device is activated, it will bring maintenance trouble and loss.

An Accord owner said on the short video platform that the cover of the new car was deformed when it hit a chicken on the road less than a month after it was bought.

Another Accord owner said that when the new car is intact, the pedestrian protection device pops up, the maintenance cost is more than 10,000, and the maintenance cycle is long, time-consuming and costly. The car owner also believes that the use of the pop-up device is one-time, the bounce has to be completely replaced, and the design is unreasonable.

Once the pedestrian protection device is started, including the engine hood, airbag computer, engine hood hinge active lifting device, collision sensor and so on, all need to be replaced, the fixed loss cost is more than 10,000 yuan.

Although this function is a good way of pedestrian protection, but under some abnormal circumstances, it not only does not play a role, but also causes burden and loss to car owners. As a result, many users try to block this function, or reduce its trigger sensitivity to solve, some of them even think that the device is a "means of increasing income." There are a large number of posts on the Internet to increase resistance and install harmonic solutions, and there are also solutions for users to reduce trigger sensitivity by adjusting the position of the sensor.

Industry insiders said, "pedestrian protection cover bullet top mechanism, whether it is Toyota Crown or Honda Accord, users complain a lot, many users directly remove the associated actuator with a resistor device to shield use." For users, it is like high-end chicken ribs or icing on the cake. It should be triggered by setting a more reasonable collapse amount sensing or modifying the detection threshold sensitivity.

Netizens said: "pedestrian protection device, routine operation, hit the dog, the dog stood up and ran away, and the cover bounced ten thousand at a time." This can not be regarded as a defect, it can only be said that it is the choice of the manufacturer's design concept, and most models will have it in the future.

As the cost of only one-time use is too high, car owners hope that manufacturers can improve it, set it up for repeated use, or further reduce maintenance costs. It is reported that Honda manufacturers have reduced maintenance costs.

Whether it is regulations or manufacturers, the original intention of setting up pedestrian protection devices is believed to be good, in order to protect the lives of pedestrians, in the event of an accident can really save lives. However, in the view of some car owners, it is not very friendly. It seems that manufacturers still need to make continuous improvements to ensure that pedestrian protection devices are triggered reasonably.
