SYSTEMS AND METHODS FOR CONTROLLING LONGITUDINAL ACCELERATION BASED ON LATERAL OBJECTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17808422 titled 'SYSTEMS AND METHODS FOR CONTROLLING LONGITUDINAL ACCELERATION BASED ON LATERAL OBJECTS

Simplified Explanation

The patent application describes a system and method for controlling the acceleration of a vehicle during autonomous driving. Here are the key points:

  • The system detects the lateral distance between the vehicle's trajectory and a nearby object.
  • Based on this distance, the system determines whether to limit the vehicle's acceleration.
  • If acceleration limiting is required, the system calculates the amount by which the acceleration should be limited based on the vehicle's trajectory and margin.
  • The system then instructs the vehicle to perform autonomous driving operations while adhering to the limited acceleration.

Potential applications of this technology:

  • Autonomous vehicles: The system can be used in self-driving cars to ensure safe acceleration while navigating through traffic.
  • Delivery robots: Autonomous delivery robots can benefit from controlled acceleration to avoid collisions with pedestrians or obstacles.
  • Industrial automation: This technology can be applied in automated vehicles used in warehouses or factories to prevent accidents during movement.

Problems solved by this technology:

  • Collision avoidance: By limiting acceleration based on the lateral distance to nearby objects, the system helps prevent collisions and improves overall safety.
  • Smooth driving experience: The controlled acceleration ensures a smoother and more comfortable ride for passengers, reducing jerky movements.

Benefits of this technology:

  • Improved safety: By considering the lateral distance to objects, the system helps prevent accidents and reduces the risk of collisions.
  • Enhanced efficiency: The system optimizes acceleration based on the vehicle's trajectory, leading to more efficient and controlled driving.
  • Passenger comfort: The limited acceleration results in a smoother driving experience, enhancing passenger comfort during autonomous journeys.


Original Abstract Submitted

Disclosed herein are systems, methods, and computer program products for controlling acceleration of a vehicle. The methods comprising: detecting a lateral distance from a point on a trajectory of the vehicle to a first object the vehicle is expected to pass when following the trajectory; selecting whether acceleration limiting is to be performed by the vehicle based on the lateral distance; obtaining a margin of the vehicle defined by a sequence of points; obtaining an amount by which the acceleration of the vehicle is to be limited based on the trajectory and the margin of the vehicle, when a selection is made that acceleration limiting is to be performed by the vehicle; and causing the vehicle to perform operations for autonomous driving with limiting of acceleration by the obtained amount.
