Description

  The present invention is an apparatus that automatically stops idling of a vehicle in the absence of a driver in order to control idling of the vehicle while the vehicle is stopped and suppress emission of carbon dioxide, which is a global warming gas, as much as possible.

  Minimizing idle idling and unmanned vehicle idling seen in cold regions in winter, etc., and minimizing unnecessary carbon dioxide emissions to help prevent global warming. I want.

  Many drivers have a selfish idea that only they are good. Regardless of the driver's will, we want to limit unnecessary idling while the vehicle is stopped, forcibly suppress wasteful CO2 gas emissions, and prevent wasteful consumption of energy.

  Stop idle idling of commercial vehicles that load and unload luggage while idling, control gas emissions and minimize wasteful energy consumption by idle idling such as taxis waiting for customers while idling I want to suppress it.

  Prevents remote engine start and long-time warm-up operation by remote control, especially in cold regions. In particular, long warm-up operations in the idling state during the winter period in cold regions are commonplace. It is normal that the inside of the vehicle is idle for a long time so that it is too hot. Idling is set to the extent that the engine is warmed up, and after reaching a certain temperature, selfish demands are suppressed and idling is forcibly stopped to minimize exhaust emissions.

Means for Solving the Invention

  Sensors are installed around the engine and the driver's seat, respectively, and the ignition current is turned on and off by the controller based on the signals generated by these sensors to minimize exhaust gas.

  The engine's ignition circuit incorporates an engine coolant temperature sensor and a driver's absence sensor, which are connected to a control device to continue warm-up operation in a cold region to a certain water temperature. When it exceeds the temperature, it automatically stops and automatically controls idling to the minimum necessary.

  The idling is continued until the cooling water temperature reaches a certain temperature, and after reaching the set temperature, the idling is automatically stopped after a short time when the absence of the driver's seat is detected by the sensor.

  After the idling is automatically stopped, when the driver returns to the driver's seat, the ignition circuit immediately returns to a restartable state and can be restarted manually as in the start.

The invention's effect

  Eliminate unnecessary long unnecessary idling such as warm-up operation in cold districts and engine start by remote control, and the exhaust gas can be minimized regardless of the driver's will.

  Driving of people who are indifferent to the emission of greenhouse gases, such as cooling and heating of parked unmanned vehicles, other people who do business such as shopping while idling, people who load and unload luggage without stopping the engine In this case, it is possible to regulate the emission of greenhouse gases.

  Regardless of the driver's will, wasteful emission of greenhouse gases can be suppressed as much as possible, contributing to the reduction of greenhouse gases as a national strategy.

  As a driver of automobiles, it is necessary to make it mandatory to cooperate in exhaust gas control.

  FIG. 1 shows a flowchart of the operation of the present invention.

  The features of the operation will be described below based on the flowchart.

  Sensor A measures the engine coolant temperature and sends the data to 2. If the temperature is 50 ° C. or less, go to 5 to determine whether to continue idling.

  When the temperature is 50 ° C. or higher, the process proceeds to 3 and the data on the presence / absence of the driver is checked by the sensor B.

It judges that it is “50 ° C. or more”, moves to 3 and waits for data on the presence / absence of the driver from the sensor B.
In the case of “yes” with a driver, a continuation signal is sent to 5 to continue the engine operation.

  When “50 ° C. or higher” is determined, the process proceeds to 3, and when “No” (absence) data is received from the sensor B as a driver presence / absence data, a circuit OFF signal is transmitted to the controller 5 and the engine is stopped.

When the driver continues idling while staying in the driver's seat, the sensor C senses that the vehicle is stopped without stepping on the accelerator pedal (not running), and stops the engine after a certain time. That is, a timer that limits the idle idling state.
When the driver is in the driver's seat and the idling state continues, if the idle idling time is long, the timer works to stop idling after a certain time and stop the exhaust gas.

Claims (2)

  A device related to idling of an internal combustion engine, in which when the driver leaves the driver's seat in the idling state, the system detects that the driver's seat is absent and automatically stops idling. If the engine coolant temperature is below a certain temperature, idling is continued until the coolant temperature reaches a certain temperature even when the driver's seat is absent.
A mechanism that automatically stops idling when the absence of a driver is detected after the water temperature reaches a certain temperature.
