Claim 10:
11. A method comprising:
providing a blind spot warning system of a motor vehicle, with the motor vehicle having a longitudinal axis, a sideview mirror, a steering wheel attached to a steering shaft that turns the motor vehicle relative to the longitudinal axis, a steering angle sensor coupled to the steering shaft for generating a steering signal associated with a wheel angle in response to the steering shaft rotating, a light projector, wherein the light projector is one of a laser and a light emitting diode, and a computer including at least one processor and a non-transitory computer readable storage medium storing instructions;
rotating, using the steering wheel, the steering shaft;
generating, using the steering angle sensor, a steering signal in response to the steering shaft being rotated;
determining, using the at least one processor, a blind spot region extending from the sideview mirror of the motor vehicle in response to the at least one processor receiving the steering signal from the steering angle sensor, with the blind spot region being spaced from a line of sight of a driver and having a current size and a current location that are based on the wheel angle, and the blind spot region having a forward boundary that is angularly spaced from the longitudinal axis by a first angle and a rear boundary that is angularly spaced from the forward boundary by a second angle;
generating, using the at least one processor, an actuation signal associated with the blind spot region; and
projecting, using the light projector, a light onto a roadway adjacent to the motor vehicle in response to the light projector receiving the actuation signal from the at least one processor, with the light indicating the current size and the current location of the blind spot region relative to the motor vehicle.
