Device for controlling vehicle travel
View Patent ↗To provide a device for controlling vehicle travel with which it is possible, when a host vehicle has malfunctioned, to prevent accidents and secondary disasters caused by the vehicle malfunction. The device for controlling travel is provided with: a malfunction detector for detecting the presence/absence of malfunctions in a variety of devices for assisting the driving of the host vehicle; a malfunction degree determining unit for specifying, when the malfunction detector detects a malfunction in any of the devices, the malfunction state of the device and determining whether or not the device can be driven; and an action instruction unit for generating, on the basis of determination information from the malfunction degree determining unit, an instruction signal for communicating an action instruction for another vehicle, and outputting the instruction signal out of the host vehicle.
1. A device for controlling vehicle travel, comprising:
a malfunction detector that detects malfunctions of various types of devices for supporting driving of an own vehicle;
a malfunction degree determining unit, when the malfunction detector detects that any device is malfunctioned, that specifies a malfunction state of the device and determines whether the device is driven; and
an action instruction unit that generates an instruction signal for changing an operation of at least one of a traffic signal in front of the own vehicle in a traveling direction thereof and another vehicle based on determination information of the malfunction degree determining unit, and outputs the instruction signal to at least one of the other vehicle and the traffic signal;
wherein the own vehicle includes an environment recognition unit, and
wherein the device for controlling travel includes a receiver that receives an external instruction signal output from the other vehicle, and a travel route changing unit that creates a collision avoidance route of the own vehicle to avoid a collision with the other vehicle based on environment information from the environment recognition unit and the determination information.
2. A device for controlling vehicle travel, comprising:
a malfunction detector that detects malfunctions of various types of devices for supporting driving of an own vehicle;
a malfunction degree determining unit, when the malfunction detector detects that any device is malfunctioned, that specifies a malfunction state of the device and determines whether the device is driven; and
an action instruction unit that generates an instruction signal for changing an operation of at least one of a traffic signal in front of the own vehicle in a traveling direction thereof and another vehicle based on determination information of the malfunction degree determining unit, and outputs the instruction signal to at least one of the other vehicle and the traffic signal;
wherein, in a case where an output destination of the instruction signal is the traffic signal, the own vehicle outputs the instruction signal to turn the traffic signal to red before and after a position of the own vehicle, or outputs the instruction signal to set a turning-on period of a red signal to be long enough for the own vehicle to pass the traffic signal.
3. A device for controlling vehicle travel, comprising:
a malfunction detector that detects malfunctions of various types of devices for supporting driving of an own vehicle;
a malfunction degree determining unit, when the malfunction detector detects that any device is malfunctioned, that specifies a malfunction state of the device and determines whether the device is driven; and
an action instruction unit that generates an instruction signal for changing an operation of at least one of a traffic signal in front of the own vehicle in a traveling direction thereof and another vehicle based on determination information of the malfunction degree determining unit, and outputs the instruction signal to at least one of the other vehicle and the traffic signal;
wherein, in a case where an output destination of the instruction signal is the other vehicle, the own vehicle outputs the instruction signal containing a position where the own vehicle is stopped or passes through while restricting the other vehicle from entering a traveling route of the own vehicle.
4. The device for controlling vehicle travel according to claim 1 ,
wherein the own vehicle is further configured to change a traveling route to a scheduled destination by the travel route changing unit, and
wherein, when the external instruction signal is received from the other vehicle, the traveling route is changed by the travel route changing unit based on position information of the other vehicle to avoid a collision therewith.
5. The device for controlling vehicle travel according to claim 1 ,
wherein, in a case where an output destination of the instruction signal is the traffic signal, the own vehicle outputs the instruction signal to turn the traffic signal to red before and after a position of the own vehicle, or outputs the instruction signal to set a turning-on period of a red signal to be long enough for the own vehicle to pass the traffic signal.
6. The device for controlling vehicle travel according to claim 1 ,
wherein, in a case where an output destination of the instruction signal is the other vehicle, the own vehicle outputs the instruction signal containing a position where the own vehicle is stopped or passes through while restricting the other vehicle from entering a traveling route of the own vehicle.
7. The device for controlling vehicle travel according to claim 6 ,
wherein the own vehicle is further configured to change a traveling route to a scheduled destination by the travel route changing unit, and
wherein, when the external instruction signal is received from the other vehicle, the traveling route is changed by the travel route changing unit based on stop position information of the other vehicle.
