Vehicle information control device, in-vehicle system, and driver assistance function information transmission device

Abstract

The present invention provides a vehicle information control device, an in-vehicle system, and a driver assistance function information transmission device that can avoid situations in which driver assistance functions become unavailable despite the vehicle being in a driving state where their use is permitted. [Solution] The vehicle information control unit 3B of the vehicle information control device 3, which is connected to the vehicle ECU 2 and the in-vehicle display device 4, is equipped with a specific road information transmission unit 34. When the vehicle is in motion, provided that it is in TV mode, the specific road information transmission unit 34 transmits road type information (specific road information) to the vehicle ECU 2 to enable the use of the driving assistance function. Alternatively, when the vehicle is in motion, provided that predetermined conditions for transmitting specific road information are met, the specific road information transmission unit 34 transmits specific road information to the vehicle ECU 2. This allows the driving assistance function to be used continuously.

Claims

1. In a vehicle information control device provided in a system having a vehicle control device that switches the use / disuse of the vehicle's driver assistance functions based on the type of road the vehicle is traveling on as a switching condition, A vehicle information control device is configured to transmit information about the type of road to the vehicle control device in order to enable the driving assistance function, provided that the vehicle is in at least a TV mode that allows television viewing while the vehicle is in motion.

2. In a vehicle information control device provided in a system having a vehicle control device that switches the use / disuse of the vehicle's driver assistance functions based on the type of road the vehicle is traveling on as a switching condition, The vehicle control device is configured to transmit information about the type of road, which enables the use of the driving assistance function, when predetermined conditions for transmitting specific road information are met while the vehicle is in motion. The in-vehicle display device, which can communicate with the vehicle information control device, is provided with either or both of the vehicle speed pulse signal and the vehicle speed signal on the in-vehicle network, as well as the GPS signal. The vehicle information control device is characterized in that the specific road information transmission condition is the occurrence of an error resulting from one or both of the provided vehicle speed pulse signal and the vehicle speed signal on the in-vehicle network indicating that the vehicle is stopped and the provided GPS signal indicating that the vehicle is moving.

3. A vehicle information control device provided in a system having a vehicle control device that switches the use / non-use of a vehicle's driver assistance function with the type of road on which the vehicle is traveling as a switching condition, The vehicle control device is configured to transmit information about the type of road, which enables the use of the driving assistance function, when predetermined conditions for transmitting specific road information are met while the vehicle is in motion. The vehicle information control device is characterized in that the conditions for transmitting specific road information are that the vehicle has traveled a predetermined distance at or above a predetermined speed, or that the vehicle has traveled for a predetermined time at or above a predetermined speed.

4. In the vehicle information control device according to claim 2 or 3, A vehicle information control device characterized in that, when the specified road information transmission conditions are not met, it controls the road type information transmitted to the vehicle control device for enabling the driving assistance function, based at least on information on the in-vehicle network.

5. In the vehicle information control device according to claim 1, 2, or 3, A vehicle information control device characterized in that, when the conditions for displaying a message are met due to one or both of the vehicle speed pulse signal and the vehicle speed signal on the in-vehicle network provided to an in-vehicle display device that can communicate with the vehicle information control device indicating that the vehicle has stopped, and the GPS signal provided to the in-vehicle display device indicating that the vehicle is moving, the device transmits information to the vehicle information control device to hide the message.

6. An in-vehicle system having a vehicle control device for switching the use / non-use of a vehicle's driver assistance function, An in-vehicle system characterized by comprising a driver assistance function information transmission unit that transmits driver assistance function information to the vehicle control device for enabling the driver assistance function, on the condition that at least one of the information output by the in-vehicle device and the information relating to the status of the in-vehicle device contains error information or inaccurate information.

7. An in-vehicle system having a vehicle control device for switching the use / non-use of a vehicle's driver assistance function, An information determination unit determines whether or not to transmit driver assistance function information to the vehicle control device to enable the driver assistance function if the information output by each of the multiple in-vehicle devices and the information relating to the status of each of the multiple in-vehicle devices include error information or inaccurate information relating to some of the in-vehicle devices, based on the information output by the other in-vehicle devices. When the information determination unit determines that the driver assistance function information should be transmitted, the driver assistance function information transmission unit transmits the driver assistance function information to the vehicle control device, An in-vehicle system characterized by having the following features.

8. An in-vehicle system having a vehicle control device for switching the use / non-use of a vehicle's driver assistance function, An in-vehicle system characterized by comprising a driver assistance function information transmission unit that transmits information to the vehicle control device for disabling the driver assistance function when the driver assistance function is enabled due to at least one of the information output by the in-vehicle device and the information relating to the status of the in-vehicle device containing error information or inaccurate information, and when the driver assistance function should be disabled.

9. A driver assistance function information transmitting device characterized by having at least the driver assistance function information transmitting unit provided in the in-vehicle system according to claim 6, 7, or 8.
