The whole complex of problems arising with the operation of the car can be divided into two categories. The first will include solvable problems, and the second - unsolvable at this stage of technological development. But there is an intermediate layer. These are problems that, with varying degrees of success, are solved by folk remedies, and only a narrow group of motorists can afford more efficient factory methods to get out of the situation. Until recently, these included the task of heating the engine. But today, even a poor driver can set autostart on the car and completely forget about the problem of a frozen power unit. Of course, such systems require investments, but the current level of costs for such devices fits into the price lists of mandatory car devices.
What is autostart?
Typical equipment includes an engine start module and controls. To organize the operation of the system, auxiliary components are also provided, including those that allow linking functional blocks into a single network. The main functional device is a blocker. If an alarm is applied to a car with auto start, then it will get more wide possibilities for regulating access to the power unit. At a minimum, it supports remote engine start. In more modern models, automatic start is also provided. For example, if the temperature drops to a certain level, then the heating is activated even without user intervention.
The second important component of autorun is the management tool. As a rule, a keychain acts in this capacity, through which the owner can give a signal at the right time. Today, even low-cost autostart on the car is installed with the ability to transmit commands through the channel of the GSM module. That is, the distance from the car to the owner does not really matter, since the signal coverage area corresponds to the range of mobile communications. Moreover, modern models support data transmission standards with the connection of satellite navigation, which also extends the potential of the control system.
With or without an alarm?
Modern car alarms in the integrated version practically cannot do without the autostart function. This is a logical combination, since in both systems the engine is activated via the same control channels. The preliminary start of the engine in this case can be considered as one of the alarm options. The central unit of the system also focuses on the control of switches for doors, shock sensors, trunk and hoods, ignition activation, brake lock, etc. The problem of combining security and heating functions is that the driver will have to bypass the immobilizer each time, which is responsible for access to all components covered by the alarm. A second key is usually provided for this. In the car, autostart is blocked through a relay, access to which is provided both through the internal button and remotely. The difficulty of accessing from a distance will depend largely on the settings that the user has made for the main key fob.
System Features
One of the most important startup options is the coverage area. There are different methods of signal transmission, and in addition to the above-mentioned GSM module, there are more reliable and high-speed radio channels, usually operating at a frequency of 434 MHz. The main coverage area most often varies from 1 to 2 km. At the same time, the radius of the keyfob is 500-1000 m. Direct control of the system is realized in this radius. Auxiliary trinkets usually have a small radius of up to 50 m. Next, you should evaluate the temperatures at which the system will operate. A typical car alarm with auto start supports its functions and control stability in conditions from -40 to +80 ° . As for power supply, in protection modes, devices usually consume current at 25 mA. The on-board voltage should be between 9-18 V.
Additional functionality
In the alarm complex functions will be represented by two categories. The first will be expressed by the protection tasks with a set of blocking options, and the second will completely cover the regulation of engine starting. But there are also individual functions that, in general, can facilitate the operation of the machine already in the context of other tasks. For example, the presence of the same GPS or GLONASS navigation sensor will allow you to determine the location of the car, record the facts of exits from the protected area, notify about evacuation, etc. Such functions, by the way, can be deprived of auto-start to the car without an alarm. On the other hand, such devices offer more advanced remote engine control capabilities. But in both cases, it is worth considering the means of self-diagnosis. For example, automatic monitoring of the state of the system will allow you to find out about possible malfunctions of critical modules until the moment when their activation is required.
Pros and cons of autorun
The indisputable advantages of such systems include the advance warming up of the engine. This eliminates the need to return to folk methods for quickly warming up the machine, which are not convenient. But the disadvantages of such systems can alert. Firstly, leaving the car unattended with the power plant turned on is dangerous in itself. Either the additional integration of mechanical locks, or the competent setting of electronic alarms, coupled with the automatic start of the engine, can prevent the risks of hijacking a wound-up car. Secondly, the integration of this system with improper connection can disrupt other functions of the car. For example, if the car does not start up several times from autorun, it is more likely that the alarm will block the starter. There are two ways to fix this problem. Either pre-configure the launch for coordinated work with a regular starter, or even disable the function of its blocking from the alarm side.
How to install autorun on a car?
The principle of operation of the autorun module is somewhat similar to the electrical circuit breaks. The installation will depend on how the powertrain is locked. Typically, a tachometer, oil sensor, or generator is used as the transition link when connecting the system to the engine. The task is simplified if the kit is suitable for a specific car model. How to install autorun on a car if it comes with an alarm? In this case, the installation of the control unit will also be required, which will also be connected to the locks, sensors and stoppers of the functional parts of the machine. Physical installation is done using an installation box and brackets, which are usually included in the kit. Wiring comes from the battery or cigarette lighter. It is desirable that all cable circuits have reliable insulation protection.
How to start a car with auto start?
Activation of the engine can be performed by the user remotely or in the programmed automation mode. In the first case, the start is realized by pressing the corresponding button on the key fob. As a rule, this is a dedicated main key, but some systems provide the ability to reconfigure by buttons. It is important to note that some situations may not allow you to activate the autostart function remotely. This control can be blocked if the parking brake is applied or the hood is open. That is, these are situations when, without car supervision, an attacker will have the opportunity to commit theft. Now another question - how to start the car with startup programmatically? To do this, you must first perform the assignment of the algorithm, according to which the system activates the start on its own. The algorithm may be based on time points or temperature sensor readings.
Conclusion
There are other ways of efficient and convenient heating of the power plant. It can be a blanket, or even a standard heating system. Why is it advantageous to install autostart on a car in order to heat the engine? This option is mainly recommended because of its convenient handling. The possibility of programming completely saves the car owner from the hassle associated with preparing the car for movement on a frosty morning. At the same time, the cost of high-tech complexes is not so high. A reliable startup system can be purchased for 7-10 thousand rubles.
