Abstract: One general aspect includes a method to indicate the space available to open a vehicle door, the method including: sensing, via a processor, a horizontal distance between the vehicle door and an object in an environment surrounding a vehicle; determining, via the processor, if the horizontal distance is greater than or less than a first threshold value; determining, via the processor, if the horizontal distance is greater than or less than a second threshold value; and providing, via the processor, an indicator based on the determination of whether the horizontal distance is greater than or less than the first threshold value and the determination of whether the horizontal distance is greater than or less than the second threshold value.
