KR20030066549A - Timer-Automobile Engine Control System - Google Patents

Abstract

PURPOSE: An automobile engine control system is provided to achieve improved user convenience and enable savings in time, while reducing fuel consumption. CONSTITUTION: An automobile engine control system is characterized in that the date and time are set manually through the use of a key pad, and an automatic switch control mode and an engine on/off mode are set by an engine start management schedule stored in an internal memory circuit. The system controls an engine start time by using a programming for memorizing the time set in the internal circuit and data corresponding to the repeated action, and transmitting the time set in the timer to the central processing unit.

Description

Engine control system using timers {Timer-Automobile Engine Control System}

(1) It is a system that can increase user convenience and save time by booking departure time reservation in a vehicle. In particular, in winter, buses and trucks outside the city cannot be parked in residential areas, so they are parked in a remotely designated parking lot. It causes fatigue accumulation and energy waste.

(2) If the driver can adjust the operating time in advance when getting off (reservation, etc.), it can save fuel and protect the environment by minimizing unnecessary engine idling.

(3) By setting several times of automatic operation and stop during the night parking, it is possible to prevent the freezing of LPG vehicles, etc., thereby improving the mechanical performance, thereby reducing resources and increasing productivity.

(4) This system can be applied to various fields such as agricultural machinery, small vessels, military equipment (tanks, etc.), fire trucks, police vehicles, emergency vehicles, etc.

(5) The operation method can be adjusted in various forms, and the mode can be set for each function to maximize user convenience (operation time, operation count, operation time, and simple functions can be adjusted in various forms, and can be adjusted in manual and automatic modes. Possible).

(6) Installation and use methods include attachment type, timer mixing type, remote control mixing type, and mobile mixing type.

(7) Safety mode can be set separately to prevent theft of the vehicle during operation.

(8) This system is applicable to all vehicles in the country where the summer season is divided, including Korea, and currently does not have similar functions in domestic and foreign luxury vehicles.

The present invention can be used without a distance / space / time / constraints to automatically start the system at a certain time.

In general, even when the user's commute time or bus departure time is constant, it is inconvenient to carry a separate remote control equipment, etc., to start the vehicle directly or with a remote controller, and to wait for a certain time after the start-up.

In cold weather, the temperature must be kept warm for engine freezing, etc., or the inconvenience caused by freezing.

In addition, emergency vehicles (fire trucks, ambulances, tanks, police cars, etc.) are often waiting 24 hours in winter. This results in significant fuel waste and air pollution. A further development is the startup management system using a remote control. However, there is a limitation of distance, and because of the limitation of the terrain, the user has to control near. And engine failure due to cold weather is a difficult problem to solve

The technical problem to be achieved in the present invention is introduced as an alternative to the above limitations and problems.

Automatic processing mode, designed circuit to be operated by controller processor by keypad, programing to transfer to controller for efficient start management, and starting for a certain period of time and having a rest period before starting several times Was administered.

Intelligent power management ensures that the vehicle starts at the correct time, and the vehicle's clock keypad adjusts the start time to save fuel. Maximized user convenience eliminates the need for separate switch operations or settings. Weather and terrain problems have been solved by automatically operating at a certain time.

If the engine is too cold in cold weather, the engine can be managed by the keypad to minimize the case of freezing and failure.

6. Overall system circuit diagram

Hereinafter, described in detail by the accompanying drawings as follows.

1 illustrates a mode in which a switch is automatically adjusted according to a startup management schedule stored in an internal memory circuit, and a state in which a reservation is manually made or a startup is turned on / off by a keypad.

Figure 2 illustrates the overall flow chart, which turns on and off the start-up at a designated time and enables manual operation by the keypad.

Figure 3 detects the time by the timer input by the central processing unit to turn the power on / off, by the input by the keypad to activate the relay by the reservation function and the user key operation and the start manager input management, The display is equipped to visually check the pressure by the keypad.

In FIG. 4, a timer that is processed in real time is separately configured to determine whether the start time coincides with the time stored in the internal circuit.

FIG. 5 shows that the central processing unit can be turned on / off when a signal is transmitted to the startup management unit by a timer and a time already stored in the startup management unit.

Intelligent power management allows the user to start at the correct time, maximizing user convenience, eliminating the need for separate switch operations or settings.

You can set the auto / manual mode as required. Weather and terrain problems have been solved by automatically operating at a certain time. The biggest effect is that it is possible to warm up for a certain time to minimize the disturbance of the cold winter weather engine.
