Emergency stopping for autonomous commercial vehicles
First Claim
1. A method for controlling an autonomous commercial highways vehicle, comprising:
- detecting a failure of a first component based on a first signal;
classifying, by an automated driving system on the vehicle, a severity of the failure of the first component;
determining to stop the vehicle, by the automated driving system on the vehicle, if the severity of the failure of the first component exceeds a threshold severity level;
determining an emergency stopping distance, by the automated driving system on the vehicle, based on the severity of the failure of the first component, a current momentum of the vehicle, and an effect of the failure of the first component on a maximum coasting distance;
determining, by the automated driving system on the vehicle, a stopping location within the emergency stopping distance; and
stopping the vehicle, by the automated driving system on the vehicle, at the stopping location.

Abstract
The present disclosure generally relates to autonomous commercial vehicles. In one aspect, the disclosure provides a method for controlling a commercial highway vehicle. The method includes detecting a failure of a first component based on a first signal from a first sensor. The method also includes classifying, by an automated driving system on the vehicle, a severity of the component failure. The method further includes determining to stop the vehicle if the severity exceeds a threshold severity level. The method also includes determining an emergency stopping distance based on the severity and a current momentum of the vehicle. The method further includes determining a stopping location within the emergency stopping distance. The method also includes stopping the vehicle at the stopping location. The present disclosure also provides an autonomous commercial vehicle and an emergency control system for performing the method.

19. An autonomous commercial highway vehicle, comprising:
-
a plurality of sensors that each monitor a respective component of the vehicle; a data bus that carries signals reported from the plurality of sensors; a memory; and a processor communicatively coupled to the data bus and the memory and configured to; detect, via the data bus, a failure of a first component based on a first signal; classify a severity of the failure of the first component; determine to stop the vehicle if the severity of the failure of the first component exceeds a threshold severity level; determine an emergency stopping distance based on the severity of the failure of the first component, a current momentum of the vehicle, and a maximum coasting distance of the vehicle without further energy provided by an engine of the vehicle; determine a stopping location within the emergency stopping distance; and control one or more vehicle components to stop the vehicle at the stopping location.
