How computers control a car on the go

    Probably, many saw or heard the news that Toyota recently recalled almost millions of its cars due to malfunctions in the brake system. So, the problem was not in mechanics, but in software.



    How seriously computers got into machine control can be viewed under the cut. And those who want to read the original text in English - can follow the link . For those who don’t have time to follow the links under the cut, there is also a little translation for the seed (note: a seasoned motorist may not find anything new for himself)

    [Addition after a somewhat strange reaction of some readers: the following text also does not call for opposing a hedgehog - namely : Some side effects of modern marketing of business-class cars and the safety of AvtoVAZ products].

    All modern cars have electronic brakes. Anti-lock braking system (ABS) detects whether the wheel is blocked, which can cause skidding, and corrects mechanical pedal depressions, if necessary, loosening the wheel lock.
    Along with ABS, from the 80s on, cars were equipped with an electronic injection system. Initially, this electronics was more of a marketing move, but now it is mandatory by law, because it is impossible to automatically control the exhaust of harmful gases without an electronic injection system, and now such an injection is even cheaper than mechanical.

    For the sake of greater efficiency and safety of cars of recent years, the use of electronics in the engine and gearbox has increased. If the driver squeezes the gas pedal, then it is the electronics that control the engine and transmission in order to optimize fuel consumption. Many computers in the car are designed to reduce the load on the driver, his convenience and ensure traffic safety. High-class cars are equipped with cruise control, which works on the basis of data from the radar and monitors the safe distance to other road users and obstacles along the way. The shock mitigation system in such cars can even press the brakes before the driver, if he himself did not manage to react.

    Any electronic system of a car that regulates and modulates its movement can be reprogrammed. Today. when the car is often a means of expression, the quality of its electronics provides sellers and successful marketing.

    Not without some side effects, however ...
    PS Gentlemen have suffered from AvtoVAZ products! "Side effects", as can be seen from the previous phrase, in this case are meant for successful marketing ! A mistake crept into the program - and the recall of huge batches of products. So forgive me generously for my unfortunate memories of such sad memories ...
