Abstract: There are provided methods, systems, and computer-readable media for maintain distance during vehicle interactions. The method comprises determining a first path for a vehicle traversing an environment, determining a second path for an object traversing the environment, determining a region of potential collision between the vehicle and the object, determining that one of the vehicle or the object is in or will be in the region of potential collision first, determining a stopping distance for at least the other of the vehicle or the object from a location in the region of potential collision, determining a current distance of at least said other of the vehicle or the object from the location in the region of potential collision, calculating a cost value based at least in part on the stopping distance and the current distance, and controlling the vehicle based at least in part on the cost value.

Abstract: Techniques for vehicle deceleration planning are discussed. The techniques include determining a first location and a first velocity of a vehicle. The techniques further include determining a second location and a second velocity of an object. Based on the first location, the second location, the first velocity, and the second velocity, a relative stopping distance between the vehicle and the object can be determined. If the relative stopping distance is less than a threshold distance, the first maximum deceleration value can be increased to a second maximum deceleration value, and the techniques determine a trajectory for the vehicle based at least in part on the second maximum deceleration value.
