Abstract

An information collection system includes an on-vehicle device and a server, wherein the on-vehicle device includes a first transmission signal transmitting part configured to transmit a first transmission signal to the server when the vehicle event is detected, and an upload executing part configured to transmit the vehicle event data to the server when the upload demand is received. The server includes a determining part configured to determine, based on the determination purposes information, when the first transmission is received, whether the information acquisition condition is met, an upload demanding part configured to transmit the upload demand to the on-vehicle device when it is determined that the information acquisition condition is met, and a vehicle event data receiving part configured to receive the vehicle event data transmitted from the on-vehicle device.

First claim

What is claimed is:

1. An information collection system, comprising:
an on-vehicle device installed in a vehicle, and
a server disposed remotely from the vehicle, the server being configured to communicate with the on-vehicle device in a bidirectional manner, wherein
the on-vehicle device includes:
a first storage,
a vehicle event detection part configured to detect a vehicle event,
a vehicle information generating part configured to generate vehicle information representing a state of the vehicle,
a data recording part configured to record vehicle event data in the first storage when the vehicle event is detected, the vehicle event data including the vehicle information for a predetermined period according to a detection timing of the vehicle event,
a first transmission signal transmitting part configured to transmit a first transmission signal to the server when the vehicle event is detected, the first transmission signal including vehicle event detection report information for informing that the vehicle event has been detected,
an upload demand receiving part configured to receive an upload demand from the server, and
an upload executing part configured to transmit the vehicle event data to the server when the upload demand is received, and wherein
the server includes:
a first transmission signal receiving part configured to receive the first transmission signal,
a second storage configured to store an information acquisition condition that is predetermined to be determined based on determination purposes information, the determination purposes information including at least one of timing-based information relevant to the detection timing of the vehicle event, type information relevant to a type of the vehicle event, and configuration information relevant to a vehicle configuration that has influence on the vehicle event,
a determination purposes information acquisition part configured to obtain the determination purposes information,
a determining part configured to determine, based on the determination purposes information, when the first transmission is received, whether the information acquisition condition is met,
an upload demanding part configured to transmit the upload demand to the on-vehicle device when it is determined that the information acquisition condition is met, and
a vehicle event data receiving part configured to receive the vehicle event data transmitted from the on-vehicle device.

2. The information collection system of claim 1 , wherein the determination purposes information includes first information,
the first information includes at least one of the timing-based information and the type information,
the first transmission signal transmitting part includes a first information acquisition part configured to obtain the first information when the vehicle event is detected,
the first transmission signal includes the first information, and
the first transmission signal transmitting part obtains the first information, which is included in the determination purposes information, from the received first transmission signal.

3. The information collection system of claim 2 , wherein the first information includes at least one of (1) first item information representing a surrounding circumstance of the vehicle at the detection timing of the vehicle event, (2) second item information representing a state of the vehicle at the detection timing of the vehicle event, (3) third item information representing the type of the vehicle event, and (4) forth item information representing a past detection situation of the same type of the vehicle event.

4. The information collection system of claim 3 , wherein the information acquisition condition includes a first acquisition condition that is predetermined and associated with the surrounding circumstances,
the first information includes the first item information,
the information acquisition condition is met when the surrounding information represented by the first item information meets the first acquisition condition.

5. The information collection system of claim 4 , wherein the vehicle event includes a plurality of types of the vehicle events,
the vehicle event detection part, the data recording part, and the first transmission signal transmitting part are provided for respective types of the vehicle events,
the first acquisition condition is set for respective types of the vehicle events,
the first information further includes the third item information, and
the information acquisition condition is met when the surrounding information represented by the first item information meets the first acquisition condition that is associated with the type of the vehicle event represented by the third item information.

6. The information collection system of claim 5 , wherein the information acquisition condition includes a second acquisition condition that is predetermined and associated with only the types of the vehicle events, and
the information acquisition condition is met when the type of the vehicle event represented by the third item information meets the second acquisition condition or the surrounding information represented by the first item information meets the first acquisition condition that is associated with the type of the vehicle event represented by the third item information.

7. The information collection system of claim 4 , wherein the first item information includes at least one of information representing a detection date/time of the vehicle event and information representing a detection position of the vehicle event.

8. The information collection system of claim 7 , wherein the determination purposes information acquisition part includes a circumstance information acquisition part configured to obtain, based on the first item information, circumstance information representing at least one of the surrounding circumstance of the vehicle at a detection date/time of the vehicle event and the surrounding circumstance at a detection position of the vehicle event, and
the determining part determines, based on the circumstance information, whether the first acquisition condition is met.

9. The information collection system of claim 3 , wherein the vehicle event includes a plurality of types of the vehicle events,
the vehicle event detection part, the data recording part, and the first transmission signal transmitting part are provided for respective types of the vehicle events,
the information acquisition condition includes a second acquisition condition that is predetermined and associated with only the types of the vehicle events,
the first information includes the third item information, and
the information acquisition condition is met when the type of the vehicle event represented by the third item information meets the second acquisition condition.

10. The information collection system of claim 1 , wherein the on-vehicle device includes a control part configured to perform automatic control or alarm control for assisting traveling of the vehicle, and
the vehicle event includes an operation of the automatic control or the alarm control.

11. The information collection system of claim 10 , wherein the on-vehicle device includes;
a detection/measurement apparatus configured to detect or measure a predetermined parameter,
a plurality of control units configured to control the vehicle, and
a communication module configured to communicate with the control units and the server in a bidirectional manner, wherein
the vehicle event detection part, the data recording part, and the control part are implemented by a predetermined first control unit of the control units,
the first storage i
