Abstract
A computer is programmed to determine a trajectory of a first vehicle. The computer is programmed to determine whether a second vehicle blocks the trajectory. Upon such determination, the computer sends an instruction to the second vehicle to adjust the second vehicle speed. The computer is programmed to determine the instruction based on the determined trajectory of the first vehicle, a second vehicle location, and a second vehicle speed.
Claims17
A computer for a first vehicle that includes at least one of an autonomous or a semi-autonomous mode, programmed to:
- determine a first trajectory for the first vehicle to change from a first lane to a second lane;
- upon determining that a second vehicle blocks the first trajectory including the change from the first lane to the second lane, determine a speed adjustment for the second vehicle that will allow the first vehicle to proceed on the first trajectory to change from the first lane to the second lane;
- and
- send, via wireless vehicle-to-vehicle communications, to a second computer in the second vehicle, an instruction based on the determined first trajectory of the first vehicle, a second vehicle location, and a second vehicle speed, wherein the instruction includes an identifier of the second vehicle and at least one target speed for the second vehicle, the target speed determined according to the speed adjustment for the second vehicle that will allow the first vehicle to proceed on the first trajectory to change from the first lane to the second lane.
A method, for a first vehicle that includes at least one of an autonomous or a semi-autonomous mode, comprising:
- determining a first trajectory for the first vehicle to change from a first lane to a second lane;
- and
- upon determining that a second vehicle blocks the first trajectory including the change from the first lane to the second lane, determining a speed adjustment for the second vehicle that will allow the first vehicle to proceed on the first trajectory to change from the first lane to the second lane;
- sending, via wireless vehicle-to-vehicle communications, to a second computer in the second vehicle, an instruction based on the determined first trajectory of the first vehicle, a second vehicle location, and a second vehicle speed, wherein the instruction includes an identifier of the second vehicle and at least one target speed for the second vehicle, the target speed determined according to the speed adjustment for the second vehicle that will allow the first vehicle to proceed on the first trajectory to change from the first lane to the second lane.
