After
passed the stages of development of independent brands the main cost, the degree of consumer desire for a functional configuration of start gradually, and as a standard to measure other joint ventures, import models, and then gradually formed a view of today’s consumers choose a car. Today, many consumers before buying a car, most will be carefully watching the configuration table, pre-assess their favorite new car price performance in the end how the car is able to meet their own needs.
For this reason, the joint venture makes a lot of brands new cars are efforts in the functional configuration. Some focus on entertainment, intelligent network linking aspects of the user experience, some of the models focus on the performance of active and passive safety; but no matter which direction is focused on, the aim is to owners who have a better, safer car feel . The best embodies the degree of convenience car configuration, to the number keyless start function. But some time ago, there are two small car accident, let us take for granted a function, a new understanding.
Shortly before ten Henan high-speed traffic police detachment in seen within the jurisdiction of the highway at 624 km in the command center of the monitor screen, the smooth flow of traffic had no idea what the reason and the slow movement of the vehicle. Arrived at the scene and found an unexpected traffic jam at the point position a kilometer away, there is a Prado was parked in the fast lane.
The reason for the stop in the fast lane wonderful also sufficient, turned out to be the owner of a hurry to go out, the return trip in the car stalled halfway only to find himself, had carelessly car keys at home; and the vehicle’s gearbox lock, the car can not be started only stop on the highway.
with another accident on a key to start the function, another is from the owner of Yangzhou, this accident is even more bizarre. Parking security personnel found a white Buick Hideo car is at idle start, but the strange thing is that the door is in a locked state; for the presence of security personnel feel more surprisingly, the car is idling has accumulated more than 24 hours , their owners still have not seen the vehicle drove away.
It is understood that the above-described Prado and Hideo are equipped with keyless start function. After starting the vehicle owners Prado left the car keys at home, and then there was later could not move in the highway. The Yangzhou Hideo owners, is not accustomed to using vehicles with keyless start functions, anxious to catch a flight directly to lock the door to leave the vehicle launch condition.
seemingly convenient keyless start Why cause these car accident, which comes to the principle of non-key start. In general, keyless start function usually combined with keyless entry (collectively referred to as PEPS system) to work together. Keyless car suggests that it is the conventional way of rotation starting key, to be operated by a start button. Without keyless entry refers to when the user wants to enter the car, simply touch the button on the door handle to unlock the door will be able to function.
in order to achieve these two functions, first of all smart car key transmission frequency signal (433MHz) and receiving a low frequency (125kHz) signal, while the motor vehicle in the ECU is responsible for receiving the high frequency signal, the low frequency signal and transmitting low-frequency antenna is connected to the vehicle interior ECU, when the two signals match, i.e., verification by can be keyless entry.
without the principle key to start, actually part of the same signal transmission. Only, PEPS system after receiving the key location determination algorithm according to the internal and the calibration data set. Essentially, PEPS system is to demarcate the border inside and outside the car, inside the car keys when entering the range to start the car.
It is determined by means of vehicle interior region of the vehicle body in the antenna intersection within the boundary determination, section determines that the vehicle exterior region by respective farthest position within the antenna side door removed. So start keyless different models functions, there will also be a key phenomenon in the door to start the vehicle, which is different PEPS system caused by the demarcation of the border. The above-mentioned two cases of small accident, believed to be the keyless start system deviation related to the key position calibration limits will let Prado owner can start the vehicle in the car, engine running time and the emergence of still achieve close and lock the door case occur.
After all, in fact, are in the habit of users after the technology brings convenience, ignoring the proper driving habits lead car. Think of another angle, when engineers design and calibration of these new features, although their designs will have redundancy, accident situation, but did not think users will engineer a way ordinary driver understood beyond to use the new features of these vehicles.

see here, some friends will think or traditional key to start will be better. From the perspective of changing habits, the key to start mechanical or reasonable for its existence. But on the other hand we can not erase this no-tech key to start brought toAnd decent use of experience and perfect technological alternation. It is thanks to new technology, just let our car life easier and comfortable compared to the past, but bear in mind that we also need to have some sense of ritual and the fear of driving behavior, in order to avoid some difficult to understand the situation appears .
