Vehicle system and vehicle controller for controlling vehicle
A vehicle system includes a road sensor mounted in a subject vehicle, the road sensor configured to detect a high occupancy vehicle (HOV) lane of a road on which the subject vehicle is traveling, and a processor coupled to the road sensor. The processor is programmed to receive a lane change request for the subject vehicle to enter or exit the HOV lane, determine, using the road sensor, whether an entrance or exit for the HOV lane is present, and upon determining that no entrance or exit for the HOV lane is present, suppress the lane change request.
1. A vehicle system, comprising:
a road sensor mounted in a subject vehicle, the road sensor configured to detect a high occupancy vehicle (HOV) lane of a road on which the subject vehicle is traveling; and
a processor coupled to the road sensor, wherein
the processor is programmed to
receive a lane change request for the subject vehicle to enter or exit the HOV lane,
determine, using the road sensor, whether an entrance or exit for the HOV lane is present, and
upon determining that no entrance or exit for the HOV lane is present, suppress the lane change request.
2. The vehicle system of claim 1 , wherein
the road sensor includes a front camera configured to acquire an optical signal of the road in front of the subject vehicle.
3. The vehicle system of claim 1 , wherein
the road sensor includes a surround view camera configured to acquire an optical signal of the road around the subject vehicle.
4. The vehicle system of claim 1 , wherein
the road sensor is a location sensor configured to detect a location of the subject vehicle, and includes a memory device having stored thereon road information describing the HOV lane of the road on which the subject vehicle is traveling.
5. The vehicle system of claim 1 , further comprising:
a vehicle passenger sensor configured to detect a number of passengers in the subject vehicle, wherein
the lane change request is a request for the subject vehicle to enter the HOV lane, and
the processor is further programmed to
determine, using the vehicle passenger sensor, whether the number of passengers is under a predetermined number, and
upon determining that the number of passengers is under the predetermined number, suppress the lane change request.
6. The vehicle system of claim 5 , wherein
the vehicle passenger sensor includes a driver monitoring camera configured to acquire an optical signal of an interior of the subject vehicle.
7. The vehicle system of claim 5 , wherein
the vehicle passenger sensor includes a seatbelt sensor that determines the number of passengers based on a number of seatbelts in the subject vehicle which are engaged.
8. The vehicle system of claim 5 , wherein
the vehicle passenger sensor includes a weight sensor that determines the number of passengers by detecting a weight applied to each seat in the subject vehicle.
9. The vehicle system of claim 1 , further comprising:
an output device coupled to the processor, wherein
the processor is further programmed to, upon suppressing the lane change request, operate the output device to notify a passenger of why the lane change request was suppressed.
10. The vehicle system of claim 9 , further comprising:
an input device coupled to the processor, wherein
the processor is further programmed to receive an input from the passenger through the input device to override the suppression of the lane change request.
11. A vehicle controller for controlling a subject vehicle, comprising:
a central processing unit; and
a memory coupled to the central processing unit, wherein
the central processing unit is coupled to a road sensor mounted in the subject vehicle, the vehicle size sensor configured to detect a high occupancy vehicle (HOV) lane of a road on which the subject vehicle is traveling, and
the central processing unit is programmed to
receive a lane change request for the subject vehicle to enter or exit the HOV lane,
determine, using the road sensor, whether an entrance or exit for the HOV lane is present, and
upon determining that no entrance or exit for the HOV lane is present, suppress the lane change request.
12. The vehicle controller of claim 11 , wherein
the road sensor includes a front camera configured to acquire an optical signal of the road in front of the subject vehicle.
13. The vehicle controller of claim 11 , wherein
the road sensor includes a surround view camera configured to acquire an optical signal of the road around the subject vehicle.
14. The vehicle controller of claim 11 , wherein
the road sensor is a location sensor configured to detect a location of the subject vehicle, and includes a memory device having stored thereon road information describing the HOV lane of the road on which the subject vehicle is traveling.
15. The vehicle controller of claim 11 , wherein
the central processing unit is coupled to a vehicle passenger sensor mounted in the subject vehicle, the vehicle passenger sensor being configured to detect a number of passengers in the subject vehicle,
the lane change request is a request for the subject vehicle to enter the HOV lane, and
the central processing unit is further programmed to
determine, using the vehicle passenger sensor, whether the number of passengers is under a predetermined number, and
upon determining that the number of passengers is under the predetermined number, suppress the lane change request.
16. The vehicle controller of claim 15 , wherein
the vehicle passenger sensor includes a driver monitoring camera configured to acquire an optical signal of an interior of the subject vehicle.
17. The vehicle controller of claim 15 , wherein
the vehicle passenger sensor includes a seatbelt sensor that determines the number of passengers based on a number of seatbelts in the subject vehicle which are engaged.
18. The vehicle controller of claim 15 , wherein
the vehicle passenger sensor includes a weight sensor that determines the number of passengers by detecting a weight applied to each seat in the subject vehicle.
19. The vehicle controller of claim 11 , wherein
the central processing unit is further coupled to an output device mounted in the subject vehicle, and
the central processing unit is further programmed to, upon suppressing the lane change request, operate the output device to notify a passenger of why the lane change request was suppressed.
20. The vehicle controller of claim 19 , wherein
the central processing unit is further coupled to an input device mounted in the subject vehicle, and
the central processing unit is further programmed to receive an input from the passenger through the input device to override the suppression of the lane change request.
