Notification device and vehicle using same

Abstract

An application processing unit executes an application that is performed as a notification device mounted in a vehicle. In the application processing unit, an input unit acquires information indicating that the vehicle is receiving driving assistance. In the application processing unit, an output unit outputs notifications to other vehicles in accordance with the information that has been acquired at the input unit.

What is claimed is: 
     
       1. A notification device mounted on a vehicle, comprising:
 a processor; and 
 a non-transitory memory, storing thereon a program that, when executed by the processor, causes the processor to: 
 an acquisition unit that acquiresacquire first information indicating that a driver's vehicle is receiving driving assistance in which a speed is controlled to allow the driver's vehicle to pass a signal with a traffic light of the signal turned green; 
 an output unit that outputsoutput first notification to other vehicles in accordance with the first informationacquired by the acquisition unit; and 
 a radio unit that transmitstransmit a packet signal including the first notificationoutput from the output unit, wherein 
 
 the acquisition unit also acquiresthe processor is further caused to:
 acquire second information indicating that a running condition is changed due to the driving assistance, and   the output unit outputsoutput second notification to the other vehicles before the running condition is changed, when the acquisition unit acquiresacquiring the second information indicating that the running condition is changed due to the driving assistance.   
 
     
     
       2. The notification device according to  claim 1 , further comprising wherein the processor is further caused to:
 a determination unit that determinesdetermine whether the running condition of the driver's vehicle approximates the running condition achieved by driving assistance, regardless of whether or not the acquisition unitprocessor acquires the first information indicating that the driver's vehicle is receiving driving assistance, and 
 when the determination unit identifies identifying similarity, the output unit similarly outputs output the information first notification as it does when the acquisition unit acquires acquiring the first information indicating that the driver's vehicle is receiving driving assistance. 
 
     
     
       3. A notification device mounted on a vehicle, comprising:
 a processor; and 
 a non-transitory memory, storing thereon a program that, when executed by the processor, causes the processor to: 
 an acquisition unit that acquiresacquire first information indicating that a driver's vehicle is receiving driving assistance in which the driver's vehicle is automatically driven; 
 an output unit that outputsoutput first notification to other vehicles in accordance with the first informationacquired by the acquisition unit; and 
 a radio unit that transmitstransmit a packet signal including the first notificationoutput from the output unit, wherein 
 
 the acquisition unit also acquiresthe processor is further caused to:
 acquire second information indicating that a running condition is changed due to the driving assistance, and   the output unit outputsoutput second notification to the other vehicles before the running condition is changed, when the acquisition unit acquiresacquiring the second information indicating that the running condition is changed due to the driving assistance.   
 
     
     
       4. The notification device according to  claim 3 , further comprising wherein the processor is further caused to:
 a determination unit that determinesdetermine whether the running condition of the driver's vehicle approximates the running condition achieved by driving assistance, regardless of whether or not the acquisition unitprocessor acquires the first information indicating that the driver's vehicle is receiving driving assistance, and 
 when the determination unit identifies identifying similarity, the output unit similarly outputs output the information first notification as it does when the acquisition unit acquires acquiring the first information indicating that the driver's vehicle is receiving driving assistance. 
 
     
     
       5. A vehicle having a notification device mounted thereon, wherein the notification device includes:
 a processor; and 
 a non-transitory memory, storing thereon a program that, when executed by the processor, causes the processor to: 
 an acquisition unit that acquiresacquire first information indicating that a driver's vehicle is receiving driving assistance in which a speed is controlled to allow the driver's vehicle to pass a signal with a traffic light of the signal turned green; 
 an output unit that outputsoutput first notification to other vehicles in accordance with the first informationacquired by the acquisition unit; and 
 a radio unit that transmitstransmitting a packet signal including the first notificationoutput from the output unit, wherein 
 
 the acquisition unit also acquiresthe processor is further caused to:
 acquire second information indicating that a running condition is changed due to the driving assistance, and   the output unit outputsoutput second notification to the other vehicles before the running condition is changed, when the acquisition unit acquiresacquiring the second information indicating that the running condition is changed due to the driving assistance.   
 
     
     
       6. A vehicle having a notification device mounted thereon, wherein the notification device includes:
 a processor; and 
 a non-transitory memory, storing thereon a program that, when executed by the processor, causes the processor to: 
 an acquisition unit that acquiresacquire first information indicating that a driver's vehicle is receiving driving assistance in which the driver's vehicle is automatically driven; 
 an output unit that outputsoutput first notification to other vehicles in accordance with the first informationacquired by the acquisition unit; and 
 a radio unit that transmitstransmit a packet signal including the first notificationoutput from the output unit, wherein 
 
 the acquisition unit also acquiresthe processor is further caused to:
 acquire second information indicating that a running condition is changed due to the driving assistance, and   the output unit outputsoutput second notification to the other vehicles before the running condition is changed, when the acquisition unit acquiresacquiring the second information indicating that the running condition is changed due to the driving assistance.   
 
     
     
       7. The notification device according to claim 1, wherein the second information indicating that the running condition is changed includes information of a right or left turn or information of a change in the speed.  
     
     
       8. The notification device according to claim 3, wherein the second information indicating that the running condition is changed includes information of a right or left turn or information of a change in the speed.  
     
     
       9. The vehicle according to claim 6, wherein the second information indicating that the running condition is changed includes information of a right or left turn or information of a change in the speed.
