Abstract

An in-vehicle device controls activation and deactivation of a monitoring device configured to monitor a suspicious person around the vehicle, and if a suspicious person is detected by the monitoring device, the in-vehicle device executes predetermined processing related to security of a user of the vehicle. The in-vehicle device includes a transmission unit configured to, if a motor of the vehicle is stopped, intermittently transmit a signal from a transmission antennas with which the vehicle is provided, a reception unit configured to receive a response signal transmitted from a portable device that has received this signal, and a controller configured to activate the monitoring device if the response signal is received.

Claims

1. An in-vehicle device configured to control an activation and deactivation of a monitoring device associated with a vehicle, the monitoring device configured to monitor a periphery of the vehicle and detect a suspicious person, and the in-vehicle device configured to execute a predetermined processing related to security of a user getting into the vehicle if a suspicious person is detected by one or more sensors connected to the monitoring device after the activation of the monitoring device, the in-vehicle device comprising a processor and a memory having instructions stored which, when executed by the processor, cause the processor to:

determine if the vehicle is stopped, and as a result of determining that the vehicle is stopped, intermittently transmit a signal to at least the outside of the vehicle from a transmission antenna with which the vehicle is provided;

receive a response signal transmitted from a legitimate portable device associated with the user, that has received the transmitted signal; and

activate the monitoring device if the processor has received the response signal from the legitimate portable device, wherein the processor;

if the suspicious person is no longer detected based on sensing information of the one or more sensors connected to the monitoring device after the predetermined processing related to security is started, measures a lapse of time from when the suspicious person is no longer detected based on the sensing information;

if the lapse of time has passed a predetermined time period from when the suspicious person is no longer detected based on the sensing information, stops the predetermined processing related to security; and

if the lapse of time has not passed the predetermined time period from when the suspicious person is no longer detected based on the sensing information, and the user performs an unlocking operation, unlocks a door of the vehicle and automatically locks the door after the door is opened and closed.

2. The in-vehicle device according to claim 1, wherein, if a predetermined time period has elapsed from a reception of the response signal from the legitimate portable device, the processor deactivates the monitoring device.

3. The in-vehicle device according to claim 1,

wherein, if a predetermined time period has elapsed from when a door of the vehicle was unlocked, the processor deactivates the monitoring device.

4. The in-vehicle device according to claim 1, wherein, if a predetermined time period has elapsed from when a motor of the vehicle was activated, the processor deactivates the monitoring device.

5. The in-vehicle device according to claim 1,

wherein the predetermined processing related to security includes at least one of (i) processing in which an interior light or an exterior light of the vehicle is turned on (ii), processing in which a horn of the vehicle is honked, (iii) processing in which an open or close door of the vehicle is locked, and (iv) processing in which information related to the suspicious person is wirelessly transmitted to the outside.

6. A vehicle security system of a vehicle comprising:

the in-vehicle device according to claim 1;

the monitoring device configured to monitor a suspicious person around the vehicle; and

the portable device configured to receive a signal transmitted from the in-vehicle device and transmit a response signal.
