Abstract
An inter-vehicle communication device for a vehicle includes: a transmission element for transmitting information about the vehicle to other vehicles with a predetermined period; a transmission controller for controlling the transmission element; and a detector for detecting a state of an indicator in the vehicle. The indicator informs a person around the vehicle about a state and existence of the vehicle, and the transmission controller controls the transmission element to transmit the information with a period shorter than the predetermined period when the detector detects that the indicator functions.
Claims14
An inter-vehicle communication device for a vehicle comprising:
- a transmission element for transmitting information about the vehicle to other vehicles with a predetermined period;
- a transmission controller for controlling the transmission element;
- and
- a detector for detecting a state of an indicator in the vehicle,
- wherein the indicator informs a person around the vehicle about a state and existence of the vehicle, and
- wherein the transmission controller controls the transmission element to transmit the information with a period shorter than the predetermined period when the detector detects that the indicator functions.
A method for communicating between vehicles comprising:
- obtaining information about a vehicle;
- detecting a speed of the vehicle;
- calculating a transmission period as a first transmission period when the speed of the vehicle is not larger than a predetermined value;
- calculating the transmission period as a second transmission period when the speed of the vehicle is larger than the predetermined value, wherein the second transmission period is shorter than the first transmission period;
- transmitting the information about the vehicle to other vehicles with the calculated transmission period;
- determining whether a hazard indicator turns on;
- determining whether the speed of the vehicle is larger than the predetermined value;
- maintaining the calculated transmission period when the hazard indicator does not turn on or the vehicle speed is larger than the predetermined value;
- and
- changing the calculated transmission period to the second transmission period when the hazard indicator turns on and the vehicle speed is not larger than the predetermined value.
A method for communicating between vehicles comprising:
- obtaining information about a vehicle;
- detecting a speed of the vehicle;
- calculating a transmission period as a first transmission period when the speed of the vehicle is not larger than a predetermined value;
- calculating the transmission period as a second transmission period when the speed of the vehicle is larger than the predetermined value, wherein the second transmission period is shorter than the first transmission period;
- transmitting the information about the vehicle to other vehicles with the calculated transmission period;
- determining whether a blinker indicator turns on;
- determining whether a brake device functions;
- determining whether the speed of the vehicle is larger than the predetermined value;
- maintaining the calculated transmission period when the blinker does not turn on, the brake device does not function, or the vehicle speed is larger than the predetermined value;
- and
- changing the calculated transmission period to the second transmission period when the blinker turns on, the brake device functions, and the vehicle speed is not larger than the predetermined value.
