prices continue to edge lower, so that more and more families, young people can easily have their own car, live a convenient car life. It is because there is a long time to get along with the car, for the car driving experience and understanding of the terms will change, there are more and more eager to “interact” with their car. Recall that in the past, and “interaction” between the car in front of basically rely on the dashboard to achieve, which is a mechanical pointer and lights, can only be done, “black and white” display: either a normal condition or situation occurs .
development of electronic technology to make our lives convenient many, cell phone pocket from the past “squares” typing, voice input into now. We understand the status of the vehicle followed up more channels, dashboard styles from the past purely mechanical layout, began to join LCD screen display other data, to the current trend of the prevalence of the full LCD screen. Now it is by adding the condition of the vehicle in the vehicle computer system information module, allowing users to more detailed understanding of various aspects of the state of the vehicle. With the pace towards intelligent “problems – prompted owners – into the store to solve the” problem solutions, it will be replaced by new technologies, such as self-healing Self-healing automotive technology.
Today’s automotive past is no longer a simple product mechanization , electronically is becoming more even able to achieve a certain degree of automation driving. Intellectualization become one of the main selling points of the current car, in order to achieve such a function, from the trip computer to the vehicle computer network systems need to be upgraded in order to achieve real-time data exchange, sharing and executed.
Remember the “Fast and Furious 8” it? This year the car was very popular movie, there is a plot to let the fans thought. In order to get the movie villain Seve secret Russian minister, the use of on-board corePiece vulnerabilities black market area of the vehicle and turn on the autopilot, forming a huge zombie car camp. This scene was originally just a movie plot, but the familiar car friends all know that in reality, to achieve black car into a host and a remote control, although difficult but can be done.
For example, a few years ago two US network security experts , Miller and Valasek use a section of the US Department of SUV car system vulnerabilities, first remote dramatically increase the volume of the car stereo, air conditioning as well as open and wiper, then you can remotely control the throttle and brakes of the vehicle.
car embodies intelligent, should not only while driving the level, should spread to other aspects of life in the car, at the same time can bring more convenience is the intelligent vehicle should go route for the user. As Tesla Model 3 above the call of the function, allowing users to within 200 meters of remote mobile vehicles, users avoid the vehicle went in the rain, and let physical disabilities groups are more likely to get on the train.
Similarly, the convenience of intelligent vehicle should also be reflected in terms of fault detection. Due to the structure of the vehicle are not familiar with, most owners know how to drive the vehicle and do not understand the maintenance of vehicles. To this end, an Israel-based start-up company Aurora Labs, a research and development since the automobile repair software. And active intervention by remote operation, failure to realize the potential problem of vehicle condition detection and handling of the vehicle.
from technical foundation repair software it comes from the behavior of code technology this is an embedded software-based technology of machine learning. Since the battery for the ECU, and many other electronicElement powered car trouble code stored in the ECU is therefore a long random access memory, when the ECU detects the system is running automatically in the background, the code will find abnormal behaviors and conditions.
When the detection mechanism of the ECU in the code error or fault code identifying the level of abnormality, will be made by analyzing the fault code, and thus determines whether the possibility of downtime. When the event is a high possibility, ECU software detection mechanism will be restored to a safe and secure version and make sure the car can be normal driving.
In addition to automatically restore software, the self-healing technique to the vehicle the OTA update also has some help. The OTA-called, a large number of sensor data is transmitted to the vehicle by the sensor, to the cloud after a consistent format for processing, and then sent back to the vehicle patches or updates. The system updates OTA auto update and intelligent products is quite similar, both need to shut down and restart the system, which makes the vehicle impossible to simultaneously achieve operational update in motion.
The OTA update is a vehicle-linked network between the car need to overcome technical, OEMs and component suppliers, in order to achieve its desired function will choose different programs and code design, different transmission protocols also stands between the different parts of the information transmission path. The self-healing technology can provide standard programming protocols, eliminating the different transport protocols between OEMs and parts suppliers caused by regeneration barriers, to achieve the target ECU update needs.
Electronic improvement in the level, so that the car needs more the TCU and the ECU auxiliary work, just the engine ECU of more than 10 million lines of code, the high-end of the intelligent network linking cars and even reached 100 million lines of code. The role of the car has become a holistic system from a mobile carrier; level when the software fails, it is possible to affect the normal use of the vehicle.
Self-healing technology appears, the fault is processed from its own software level, to avoid a wide range of data and complex software systems are affected and then let other function failure. On the other hand, Self-healing also broke all kinds of vehicle components had “fragmented” approach, using standard programming protocols deal with issues and updates, for the Alliance of Automobile network provides the technical basis for security.
