Description

The present invention specifies a vehicle used or used for crimes from a general vehicle, and remotely controls the vehicle to stop and stop the output of the engine (motor) of the vehicle by a remote operation. The present invention relates to a vehicle capturing method and an engine control system.

Technical background

In recent years, vehicles have been used for a wide variety of crimes such as runaway, theft, kidnapping, and terrorism, and it has become important to find out the vehicle used for the crime as quickly as possible to prevent the next crime.

In general, in order to identify vehicles used for crimes, it is necessary to identify the vehicle's color, size, type, number of doors, etc. It has become. Further, in order to stop the vehicle, there are many places that rely on the driver's intention, and it is very difficult to stop the vehicle of the driver who does not intend to stop safely.

In addition, a method and device that reads the number on the license plate, identifies the vehicle from the number, and lowers the traveling speed by remote control has been proposed. It is also assumed that the vehicle cannot be identified. Also, there are no early vehicle identification methods for crime resolution means such as kidnapping cases or effective means for preventing terrorist acts by vehicles.

Problems to be solved by the invention

The object of the present invention is to reduce the investigation time and labor by the police officer's vehicle identification work, and to establish a reliable and quick vehicle identification method and a safe stop system that do not depend on the license plate number.

Means for solving the problem

This device uses a device that transmits and receives several types of signals attached to the vehicle and a device that transmits and receives several types of signals that are attached to police cars and important facilities to identify dangerous behavior vehicles from the reception time and reception level of the signals. A signal is sent from this device attached to an important facility, and the vehicle-side engine control system (ECU) and ignition are remotely controlled from this device attached to the vehicle side to forcibly stop the vehicle from engine stop and idling. It is an apparatus and method, and it is not necessary to visually check the number of the license plate, and it is possible to avoid a sudden stop state. FIG. 1 shows a flowchart of the present apparatus.

This device (hereinafter referred to as a vehicle-side device) is attached to a general vehicle (FIG. 2). The function of the vehicle side device has an individual number (referred to as an authentication number) for distinguishing the vehicle, and is based on a reception function of an authentication number transmission request signal (hereinafter referred to as an inquiry signal), an authentication number transmission function, and a confirmation signal. It has an alarm system issuing function inside and outside the vehicle, a function for receiving an engine stop or idling signal (hereinafter referred to as a control signal), a control function for controlling an ECU, and the like.

Attach this device to a police car or a facility to be managed. This apparatus attached to the police car side is called a police car side apparatus, and this apparatus attached to a facility to be managed is called a facility side apparatus. The functions of both the police car side and the facility side devices include an inquiry signal transmission function, an authentication signal reception function, a confirmation and control signal transmission function, a screen for displaying the authentication signal and supplementary data, and a captured data recording function. (Figure 3)

The inquiry signal is transmitted only while the inquiry signal is received, and the individual device number is always transmitted from the vehicle side device so as not to adversely affect the electronic equipment in the surrounding electric field strength. It is desirable to do. You can use any number (authentication number) for identifying the vehicle, but it is better to use the vehicle number on the car inspection card or the number on the license plate so that you can identify the owner of the vehicle. Judging from the convenience at the time of installation of this apparatus, a chassis number or the like given before selling the vehicle is desirable. The authentication signal is a transmission / reception signal of an authentication number of the vehicle side device. The confirmation signal informs the driver of the dangerous vehicle that it is currently being caught, warns the driver by voice or horn, etc. in order to urge the driver to stop at his own will, and also operates the police car side device. Is a signal that blinks a brake lamp or parking light that can visually check the vehicle.

When a police car on the road (A vehicle in FIG. 4) finds a dangerous vehicle that is running and issues a stop instruction, but the dangerous vehicle ignores the stop instruction, an inquiry signal is sent from the police car side device to the vehicle side device. The vehicle-side device that has received the inquiry signal transmits the authentication signal, but the police-car-side device receives a plurality of irrelevant general vehicle authentication signals within the communication range as shown in the police-car-side screen of FIG. Become. Therefore, while confirming the supplementary time of the authentication signal that changes on the monitor screen by tracking driving, the authentication signal captured for the longest time is determined to be a dangerous vehicle and a confirmation signal is transmitted.

In FIG. 4A-2, when it is assumed that a few seconds have elapsed from FIG. A-1, vehicle B at the time of inquiry signal transmission (FIG. 4-1) (vehicle B was blamed on the shoulder for patrol car traveling) Assuming that the authentication signal of the opposite lane E is still captured, the dangerous vehicle cannot be identified from the reception time. Further, even at the reception level, it cannot be specified due to the influence of the authentication signal of the vehicle E returning from the vehicle in the opposite lane. However, in Fig. 4-3, a few seconds have passed since Fig. A-2, the vehicle at the time of capture has gone out of the communication distance, so it disappears from the screen, and a new L, M, N, K vehicle is captured. From this, it can be seen that the acquisition time of the authentication signal of the vehicle other than the D vehicle in FIGS. 4 and 3 is short, and the supplementary time of the authentication signal of the D vehicle is the longest. The dangerous vehicle can be identified as the vehicle D from this capture time.

In addition, as shown in Fig. 5, when protecting facilities from terrorist acts using vehicles, the radio wave coverage is limited, so it is unlikely to affect electronic devices, so send inquiry signals at regular intervals. Then, the authentication signal is set to the capture state. In Fig. 5-1, it can be inferred that the C vehicle stops and is close to it because the reception time of the authentication signal of the C vehicle is long and the reception level has not changed. It cannot be specified. If the vehicle position that has passed the time from FIG. 5-1 is taken as FIG. 5-2, the authentication signal has become stronger with the passage of time from FIG. The reception level is not possible. 5-3 assumes that the vehicle B is approaching the management facility rapidly from the reception time and reception level of FIG. From this, the vehicle B is determined to be a dangerous vehicle.

Both the police car side and the facility side can send a control signal to the vehicle side device at the above-mentioned time point, but the meaning of prompting the driver to stop and the police car side device to identify the vehicle more reliably A confirmation signal is transmitted to the vehicle side device. The vehicle-side device that has received the confirmation signal notifies the inside of the vehicle by horn or voice, and the police officer who operates the police car-side device blinks the brake lamp or parking light to visually confirm the vehicle.

If there is no problem in identifying the vehicle by blinking the brake lamp of the vehicle to be stopped by visual confirmation, a control signal is transmitted from the police car side device to the vehicle side device. The vehicle-side device that has received the control signal sends a signal such as engine (motor) stop or engine (motor) output suppression to the ECU, and brings the engine (motor) to a stop or idling state to stop the vehicle. When the vehicle main body does not have an ECU, the ignition side cutting or the like is directly performed by the vehicle side device.

When the safety confirmation is completed, a reset signal is sent from the police car side device to the vehicle side device to initialize the vehicle side device. By this initialization, the engine (motor) returns to a state where it can run.

Next, the device for identifying the vehicle when used for crimes such as kidnapping, sends an inquiry signal to the vehicle-side device at regular intervals, like the facility-side device, and authenticates the vehicle passing within the capture range. Added a function to automatically record changes in number, supplemental date / time, reception time, supplementary reception level and a function to send record data in response to a record read request signal from a police car side device, etc., and a data display screen and confirmation signal / control No signal transmission function is required.

When there is an incident such as kidnapping and it is necessary to identify the vehicle, the vehicle is identified based on the data recorded in the device at the same time zone as the time of the kidnapping. In FIG. 6, nine units from (1) to (9) are set as the capture points at the intersection of school roads, and the children are missing around X: X o'clock on X month X around X. First, it is read from the data of the devices (4) and (6) near the missing place, and from the recorded data of FIG. It is understood that the vehicle has passed the vehicle, and only the C vehicle in the vehicle has a capture time that cannot be a normal run. Further, the reception level data of devices (4) and (6) can be seen from FIG. 6-2 that the C vehicle was temporarily stopped because the reception level did not change temporarily. If it is normal, you can stop the vehicle, but the vehicle C is identified as an important reference vehicle because it was stopped at the same time on the day of the missing incident. By comparing the authentication numbers of this device, the owner of the vehicle can be specified. In addition, by examining the records of the surrounding device, it is also possible to determine where the important reference vehicle came from and where it left.

The invention's effect

This device has a very simple function and structure for both the vehicle side, the police car side, and the facility side device, and can be carried by automation from the transmission of the inquiry signal to the transmission of the control signal and reduction in size and weight. In addition, a crime suppression effect can be expected by displaying that this device is installed in a school road or the like.
