Will new technology reduce the safety of the car?

From leaded dyed toys to food contaminated with bacteria, product recalls exist in all walks of life. However, in recent years, vehicle recalls have been caused by technical reasons.

For example, in 2009, Volvo announced the recall of the car because the on-board software could not deliver the correct signal to the fuel pump, which could lead to a sudden stop or crash. At about the same time, Yamaha announced the recall of motorcycles that were produced between October 2004 and April 2005. Because of problems with the sensor on the valve, it could lead to abrupt flameouts and crashes. Not long afterwards, Daimler Truck Company also announced a recall because the LED lights of the Thomas School Bus made it difficult for the driver to see the road surface.

High-tech systems began to be used in the automotive sector in the 1980s. Today, automotive electronics systems and engine engines can solve everything from fuel regulation to fault diagnosis. Most cars today have 30 -80 independent electronic controllers. Some devices will obviously affect the safety performance of the car.

Two examples are: adaptive cruise system, if a car rushes directly in front of your car, the system will automatically decelerate; there is a lane assist system, if the driver goes in the wrong lane without indicating, the system will Will make a reminder. Systems like this raise a logical question: Should the car not be handed over to intelligent systems management? In addition, people will not rely too much on automation? However, as these technologies have just emerged, it is still too early to determine their impact on the safety performance of the car.

The security impact of other systems is less of a concern. The on-board computer provides the driver with a way to control multiple devices in the car.

For example, the BMW Smart Driving Control System includes a handle and a screen through which you can control the car stereo, driving route and air conditioning system. This leads the driver to concentrate on the road conditions when operating it. This system is used on most BMW cars, and car manufacturers such as Audi and Mercedes also use similar smart electronic systems. Driving on a wide, freeway in Germany, it doesn't matter if the decentralized points are focused on the road conditions to operate an intelligent system, but on congested American roads, this can cause safety problems.

In today's society, automotive sensors are everywhere. Sensors with a simple function such as inductive outdoor temperatures, if they fail, may not cause major problems. However, some automotive sensors are responsible for some important tasks. Once they fail, they will directly affect traffic safety. For example, some sensors can maintain proper gear speeds by measuring the angle of the car, and other sensors can sense whether the tires are slipping in bad weather. This is a signal for turning on the electronic stability control system of an automobile.

Like other computer system failures, automotive sensors may experience errors. Although unlikely, or due to hardware and software failures connecting them, they can also cause safety problems. However, as of now, the advantages of these systems outweigh the disadvantages.
