Abstract

A vehicle-mounted control system to prevent an execution of an improper request of a center apparatus is provided. The vehicle-mounted control system executes an impropriety determination process, which determines whether a center request signal is an improper signal, based on circumstance information representing a circumstance where a vehicle is placed. Accordingly, it may be possible to determine whether the center request signal is an improper signal transmitted by an operation of a center apparatus by an improper person. When it is determined as the improper center request signal (S2: No), a vehicle control based on the center request signal is not executed.

Claims

1. A vehicle-mounted control system comprising:

a center request receiver receiving a center request signal transmitted from a center apparatus placed outside a vehicle so as to request a predetermined control to the vehicle;

a control execution portion executing a vehicle control based on the center request signal received by the center request receiver; and

an impropriety determination portion determining whether the center request signal transmitted by the center apparatus is an improper signal transmitted by an operation of the center apparatus by an improper person, based on circumstance information representing a circumstance where the vehicle is placed, wherein

the control execution portion does not execute the vehicle control based on the center request signal when the impropriety determination portion determines that the center request signal transmitted from the center apparatus is an improper center request signal.

3. The vehicle-mounted control system according to claim 1 comprising:

a user request receiver receiving a user request signal transmitted from a portable apparatus carried by a user of the vehicle so as to perform a remote control of the vehicle;

an authentication portion authenticating whether the user carrying the portable apparatus is a regular user of the vehicle; and

a priority level change portion being made a priority level of the user request signal higher than the priority level of the center request signal when the authentication portion authenticates that the user carrying the portable apparatus is the regular user, wherein

the control execution portion executes a control having a higher priority level of the center request signal and the user request signal when the control execution portion receives the center request signal and the user request signal, and control contents requested by the center request signal and the user request signal mutually conflict.

4. The vehicle-mounted control system according to claim 1, wherein

the impropriety determination portion uses at least one of location information of the vehicle and time information as the circumstance information.

5. The vehicle-mounted control system according to claim 1, comprising

a notification portion notifying a user of the vehicle of a determination result when the impropriety determination portion determines that the center request signal corresponds to the improper center request signal.

6. The vehicle-mounted control system according to claim 1, wherein

the control execution portion is configured from a plurality of ECUs, and

the impropriety determination portion is provided with one ECU, which is connected to the plurality of ECUs configuring the control execution portion.

2. A vehicle-mounted control system comprising:

a center request receiver receiving a center request signal transmitted from a center apparatus placed outside a vehicle so as to request a predetermined control to the vehicle;

a user request receiver receiving a user request signal transmitted from a portable apparatus carried by a user of the vehicle so as to perform a remote control of the vehicle;

a control execution portion executing a vehicle control based on the center request signal and the user request signal received by the center request receiver and the user request receiver;

an authentication portion authenticating whether the user carrying the portable apparatus is a regular user of the vehicle; and

a priority level change portion being made a priority level of the user request signal higher than the priority level of the center request signal when the authentication portion authenticates that the user carrying the portable apparatus is the regular user, wherein

the control execution portion executes a control having a higher priority level of the center request signal and the user request signal when the control execution portion receives the center request signal and the user request signal, and control contents requested by the center request signal and the user request signal mutually conflict.

7. A vehicle-mounted control device comprising

an impropriety determination portion determining whether a center request signal transmitted by a center apparatus is an improper signal transmitted by an operation of the center apparatus by an improper person, based on circumstance information representing a circumstance where a vehicle is placed.

8. The vehicle-mounted control device according to claim 7, wherein

the vehicle-mounted control device functions as a gateway ECU connected to a plurality of control execution portions executing a vehicle control based on the center request signal through a communication line.

9. The vehicle-mounted control device according to claim 7, further comprising:

an authentication portion authenticating whether a user carrying a portable apparatus is a regular user of the vehicle; and

a priority level change portion being made a priority level of a user request signal transmitted from the portable apparatus higher than a priority level of the center request signal when the authentication portion authenticates that the user carrying the portable apparatus is the regular user.

10. The vehicle-mounted control device according to claim 9, further comprising:

a notification portion notifying the user of the vehicle of a determination result when the impropriety determination portion determines that the center request signal corresponds to an improper center request signal.
