Abstract
A method for controlling the acceleration rate of a vehicle based on the vehicle's location includes determining, via one or more sensors, that the vehicle is at a first location and reducing the vehicle's initial target acceleration rate to a first adjusted target acceleration rate in response to the location satisfying a first location condition. Subsequently, the method includes determining that the vehicle has reached a second location and increasing the first adjusted target acceleration rate to a second adjusted target acceleration rate in accordance with determining that the vehicle has reached the second location. This method can be applied to vehicles operating in autonomous or semi-autonomous modes.
Claims17
A method for controlling an acceleration rate of a vehicle, comprising:
- determining, via one or more sensors associated with the vehicle, that the vehicle is at a first location, the vehicle being at a standstill at the first location, the first location is a crosswalk or an intersection;
- reducing an initial target acceleration rate of the vehicle to a first adjusted target acceleration rate in accordance with the location satisfying a first location condition;
- determining, via the one or more sensors, that the vehicle has moved from the first location to a second location;
- increasing the first adjusted target acceleration rate to a second adjusted target acceleration rate in accordance with determining the vehicle is at the second location.
An apparatus for controlling an acceleration rate of a vehicle, comprising:
- at least one processor;
- and
- at least one memory coupled with the at least one processor and storing instructions operable, when executed by the at least one processor, to cause the apparatus to:
- determine, via one or more sensors associated with the vehicle, that the vehicle is at a first location, the vehicle being at a standstill at the first location, the first location is a crosswalk or an intersection;
- reduce an initial target acceleration rate of the vehicle to a first adjusted target acceleration rate in accordance with the location satisfying a first location condition;
- determine, via the one or more sensors, that the vehicle has moved from the first location to a second location;
- and
- increase the first adjusted target acceleration rate to a second adjusted target acceleration rate in accordance with determining the vehicle is at the second location.
A non-transitory computer-readable medium having program code recorded thereon for controlling an acceleration rate of a vehicle, the program code executed by at least one processor and comprising:
- program code to determine, via one or more sensors associated with the vehicle, that the vehicle is at a first location, the vehicle being at a standstill at the first location, the first location is a crosswalk or an intersection;
- program code to reduce an initial target acceleration rate of the vehicle to a first adjusted target acceleration rate in accordance with the location satisfying a first location condition;
- program code to determine, via the one or more sensors, that the vehicle has moved from the first location to a second location;
- and
- program code to increase the first adjusted target acceleration rate to a second adjusted target acceleration rate in accordance with determining the vehicle is at the second location.
