Abstract

A communication system for a vehicle includes: a plurality of controllers mounted on the vehicle; a data communication network for coupling the plurality of controllers with each other so that the controllers transmit data to and receive data from each other via the data communication network; a failure diagnosis device for diagnosing whether each controller is normal; a failure diagnosis activation device for activating the failure diagnosis device; and an avoiding condition setting device for setting an avoiding condition, which provides to avoid execution of the failure diagnosis when the failure diagnosis device is activated.

Claims

1. A communication system for a vehicle comprising:

a plurality of controllers mounted on the vehicle;

a data communication network for coupling the plurality of controllers with each other so that the controllers transmit data to and receive data from each other via the data communication network;

a failure diagnosis device for diagnosing whether each controller is normal;

a failure diagnosis activation device for activating the failure diagnosis device; and

an avoiding condition setting device for setting an avoiding condition, which provides to avoid execution of failure diagnosis when the failure diagnosis device is activated.

2. The communication system according to claim 1,

wherein the avoiding condition setting device has a function for canceling the avoiding condition.

3. The communication system according to claim 1,

wherein the plurality of controllers includes an in-vehicle navigation device, and

wherein the in-vehicle navigation device provides the failure diagnosis device, the failure diagnosis activation device and the avoiding condition setting device.

4. The communication system according to claim 3,

wherein the in-vehicle navigation device displays an initial screen when the in-vehicle navigation device turns on, and

wherein the in-vehicle navigation device controls the avoid condition setting device to set the avoiding condition when a predetermined special key operation is performed on the initial screen.

5. The communication system according to claim 4,

wherein the in-vehicle navigation device controls failure diagnosis activation device to activate the failure diagnosis device when another predetermined special key operation is performed on the initial screen.

6. The communication system according to claim 5,

wherein the in-vehicle navigation device determines whether the avoiding condition is met,

wherein the failure diagnosis device executes the failure diagnosis when the in-vehicle navigation device determines that the avoiding condition is not met, and

wherein the failure diagnosis device does not execute the failure diagnosis when the in-vehicle navigation device determines that the avoiding condition is met.
