no. 1 Embodiment approach

[0025] figure 1 It is a functional block diagram showing an example of the functional configuration of the route search system 1 according to the first embodiment of the present invention. The route search system 1 of the present embodiment is composed of a server device 10 and a high-precision map management device 20 . The server device 10 is installed in a predetermined place such as a data center. The high-resolution map management device 20 is a type of electronic control unit (ECU: Electronic Control Unit) mounted on a vehicle, and is configured using, for example, an MPU (Micro Processing Unit, micro processing unit). The server device 10 and the high-resolution map management device 20 are connected to each other via a mobile phone line or a public communication network such as the Internet. In this system, a plurality of vehicles equipped with the high-resolution map management device 20 are managed.

[0026] The server device 10 includes a server map database (her...

no. 2 Embodiment approach

[0065] Next, a route search system according to a second embodiment of the present invention will be described. The path search system of this embodiment has the same figure 1 The same functional configuration as the route search system 1 of the first embodiment described above. Therefore, the following uses figure 1 The functional configuration of the route search system of this embodiment will be described.

[0066] Figure 5 It is a figure explaining the outline|summary of 2nd Embodiment of this invention. exist Figure 5 In , the range indicated by reference numeral 61 represents the map range covered by the server map information stored in the server map DB 101 in the server device 10 (hereinafter referred to as "server map range"). In addition, the range indicated by reference numeral 62 represents the map range covered by the high-resolution map information stored in the high-precision map DB 201 in the high-precision map management device 20 (hereinafter referred ...

no. 3 Embodiment approach

[0083] Next, a route search system according to a third embodiment of the present invention will be described. The path search system of this embodiment has the same figure 1 The same functional configuration as the route search system 1 of the first embodiment described above. Therefore, the following uses figure 1 The functional configuration of the route search system of this embodiment will be described. Hereinafter, the description of the case where the same processing as in the first embodiment is performed will be omitted. In this embodiment, an example of a case in which the departure location is different from the current location of the vehicle will be described.

[0084]In this embodiment, a case where the user calls a taxi to an arbitrary departure point facility and moves to an arbitrary destination facility by operating an information terminal will be described as an example. Users can designate any facility as a departure point as well as a destination. Des...

Abstract

An electronic control device acquires route information to a destination on the basis of first map information, and if a part of the route to the destination is outside of a map range of either the first map information or second map information having a map range different from the first map information, transmits the acquired route information to the destination on the basis of the second map information. The destination is changed, and a route to the destination based on the second map information is generated.

Description

technical field [0001] The invention relates to an electronic control device. Background technique [0002] Devices that search for a route to a destination using map information and guide a vehicle according to the searched route are widely used. In such a device, there is a problem that route search cannot be performed when there is a place where map information cannot be acquired between the current location and the destination. [0003] Patent Document 1 is known as prior art related to the invention of the present application, for example. Patent Document 1 discloses a route search device in which detailed map data that is different from normal map data and capable of short-distance route search is stored in advance, and when the current location deviates from the route Next, until a new route search is completed, a temporary destination is set a certain distance ahead along the traveling road, and a temporary route is searched based on detailed map data. [0004] pr...
