Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle theft detection device having a plurality of types of sensors including a tilt sensor for detecting a tilt of a vehicle as a sensor for detecting theft. More specifically, the present invention relates to a vehicle theft detection device having a multi-story parking mode in which a notification operation is not performed even if the inclination sensor detects when parking in a multistory parking lot. 2. Description of the Related Art An abnormal inclination, vibration, or door opening of a vehicle is detected by a sensor, and when an abnormality is detected, a GPS (global) is detected.
bal positioning system (global positioning system) is used to calculate the current position of the vehicle, and an abnormal signal is sent to a remote monitoring center of the current position data by wireless transmission using a mobile phone system or the like. It has come to be. [0003] The above-mentioned vehicle theft detection device utilizes an unnatural inclination of the vehicle when attempting to steal the vehicle using, for example, a towing vehicle. For example, the inclination of the vehicle at the time when the theft detection device is set to the alert state is stored, and the inclination sensor detects an abnormality when the vehicle is unnaturally inclined thereafter. However, for example, when the vehicle is parked in a multi-story parking lot, in addition to the theft by the towing vehicle as described above, the vehicle may shake or tilt due to the movement of the pallet in the parking lot when entering or leaving the vehicle. In the detection device,
There is a problem that the tilt sensor operates to perform an alarm operation. [0004] In order to solve the above problems, a vehicle theft detection device according to the present invention comprises at least an inclination sensor for detecting the inclination of the vehicle and an event associated with a theft other than the inclination of the vehicle. A three-dimensional parking mode having a theft detection sensor for detecting theft, and performing an alarm operation when a theft detection sensor other than the inclination sensor detects the detection, and a parking operation performing an alarm operation when the theft detection sensor including the inclination sensor detects the detection.

Reference numeral 1 denotes a CPU, a ROM storing a control program, and a RAM
The operation of the transmission unit 503 and the display unit 504 is controlled by an operation signal from the operation unit 502. Here, three operation modes that can be set in the main unit 41 using the remote control unit 50, that is, "parking mode", "multi-level parking mode", and "release mode" will be described. The “parking mode” is a mode that is set when the user of the vehicle parks the vehicle and leaves the vehicle. When the parking mode is set, when the main unit 41 receives a detection signal from any of the tilt sensor 43, the door open sensor 44, and the engine start sensor 45, the main unit 41 determines that theft has occurred, and determines that an abnormality described later has occurred. Perform notification operation. The “multilevel parking mode” is a mode set when the vehicle is parked in a multilevel parking lot. When the multi-story parking mode is set, the main unit 41 does not perform the abnormality notification operation even when receiving the abnormality signal from the inclination sensor 43. However, when a detection signal is received from the door open sensor 44 and the engine start sensor 45, an abnormality notification operation is performed.
The "cancel mode" is a mode set when the user of the vehicle uses the vehicle. The abnormality notification operation is performed even if a detection signal is received from any of the inclination sensor 43, the door open sensor 44, and the engine start sensor 45. Do not do. Next, the operation of setting the main unit 41 to the multi-story parking mode will be described. The user of the vehicle parks the vehicle in the multi-story parking lot, goes out of the vehicle, and locks the vehicle door.
The user presses the multi-level parking mode switch 507 of the remote control unit 50. Control unit 50 of remote control unit 50
When detecting that the multi-story parking mode switch 507 has been operated, the transmission unit 503 wirelessly transmits a setting command to the multi-story parking mode by a weak radio wave. Note that the transmission signal includes an ID code for authenticating whether or not the signal is from a predetermined remote control unit 50. When the main unit 41 receives a wireless signal from the remote control unit 50 via the antenna 415 and the remote control communication I / F 414, the main unit 41 transmits the signal from the remote control unit 50 which is predetermined by an ID code included in the signal received by the control unit 41. Authenticates whether the signal is
In the case of K, the operation mode is set to the “multilevel parking mode” and stored in the RAM. The operation for setting the “parking lot mode” or the “release mode” is the same as described above. Next, an example of the processing performed by the main unit 41 will be described with reference to the flowchart of FIG. The main unit 41 monitors via the sensor I / F 413 whether or not a detection signal is input from any of the tilt sensor 43, the door open sensor 44, and the engine start sensor 45. (Step S01) Here, when the detection signal from the sensor is received, it is determined whether or not it is the signal of the inclination sensor 43. (Step S02) When the signal is from the inclination sensor 43, it is determined whether or not the set operation mode is the “parking mode”. (Step S03) Here, when the mode is not the “parking mode”, since the “multi-level parking mode” or the “release mode” is set, the alarm operation is not performed, and the process returns to the step S01. In the case of the "parking mode", it is determined that theft has occurred, and an alarm operation is performed. The alarm operation will be described later. If it is determined in step S02 that the sensor is a sensor other than the tilt sensor 43, that is, the door open sensor 44 or the engine start sensor 45, it is determined whether the operation mode is the "release mode". (Step S04) If it is determined that the mode is the "release mode", the alarm operation is not performed, and the process returns to step S01. "Release mode"
If it is determined that the parking mode is not the same, that is, if the parking mode or the multi-story parking mode is set, an alarm operation is performed. (Step S05) Here, the alarm operation will be described. When the alarm operation starts, the main unit 41 transmits a notification command to the communication / position detection terminal 42. When the communication / position detection terminal 42 receives the report command via the connection I / F 425,
Operate the GPS position measurement function, and set the antenna 423, RF
The unit 422 receives a GPS signal. Next, using the cellular phone function, the communication terminal 2 connects to the position information management server 31 via the communication network 2, corrects the position and calculates an accurate current position, and transmits the result to the communication / position detection terminal. 42, and transmits an abnormal signal indicating that the inclination sensor has detected the position information together with the position information to the emergency response server 32 of the emergency response center 1 via the communication network 2. At the same time, the main unit 41 sounds the siren 49 and notifies the surroundings of the occurrence of theft. In this embodiment, the remote control unit 5
0 operation unit, parking mode switch 503, display unit 5
04 and the release switch 508 are provided independently, but the invention is not limited to this. For example, two switches are provided, and the parking mode and the release mode are alternately switched by pressing one of the switches. When set, the parking mode may be set by pressing another switch within, for example, 5 seconds after setting the parking mode. According to the vehicle theft detection device of the present invention, the vehicle can be used even when parking in a multi-story parking lot or the like where the vehicle is expected to incline. It is possible to prevent an alarm operation by sensing at.
