Electronics In Today’s Cars

In today’s cars, electronics and computers have replaced many mechanical components This has been done to improve security, but are we sure about this improved safety? Or maybe the electronics have introduced a new kind of risk? Let’s study together which parts of a car have been upgraded with computer components.

First there is the cruise control that uses an electronic control module to maintain a fixed speed decided by the driver. The module actually sends a signal that opens or close the throttle and in this way a specific speed is maintained. But what happens if there is a fault in the system and the driver can’t disengage the control?

The anti lock braking systems are also controlled by electronics. They modulate the braking force during a stop and this should lower the risk of an emergency stop because the wheels do not lock, keeping the car in a controllable situation.

The most powerful computer system in a today’s car in the engine control module, which controls the engine using sensors on oxygen, exhaust gases, temperature and more. All of this info is used to calculate how much fuel should be injected into the engine. The aim of course is to have the best performance with the lowest fuel usage. But if the engine control module fails, the engine can stop.

The door locks are another mechanism which is electronically controlled. Operated by a remote control, they can be activated or deactivated at a distance, along with an alarm. Since the radio frequencies used can be influenced by other radio sourced, there could be situations where the door locks can’t be opened or closed and you can imagine the risk.

The power steering is another electronic mechanism, an electronically controlled power assisted steering which uses sensors to give information about the motion of the wheel to a computer unit. The aim is to reduce the physical effort required from the driver during the steering.

As you see, seems that computers and electronics are everywhere in today’s world so a correct information about computers and all their functions is really necessary for anyone.
