Abstract
A vehicle control system includes a controller circuit in communication with a steering sensor and one or more perception sensors. The steering sensor is configured to detect a steering torque of a steering wheel of a host vehicle. The one or more perception sensors are configured to detect an environment proximate the host vehicle. The controller circuit is configured to determine when an operator of the host vehicle requests a take-over from fully automated control of the host vehicle based on the steering sensor. The controller circuit classifies the take-over request based on the steering sensor.
Claims25
A vehicle control system, comprising:
- a controller circuit configured to:
- receive, from a steering sensor, a steering torque of a steering wheel of a host vehicle;
- receive, from one or more perception sensors, an environment proximate the host vehicle;
- responsive to a determination that the steering torque meets a first threshold, determine that an operator of the host vehicle requests a take-over from fully automated control of the host vehicle;
- responsive to the determination that the operator of the host vehicle requests the take-over from fully automated control of the host vehicle, classify, based on at least one of a steering angle and a steering angle rate or the environment proximate the host vehicle, the take-over as one of a plurality of take-over types;
- determine, based on the take-over type for the take-over and on the environment proximate the host vehicle, a level of automated driver assistance of the host vehicle;
- and
- operate the host vehicle according to the determined level of automated driver assistance.
A method of operating a vehicle control system,
- the method comprising:
- receiving, from a steering sensor, a steering torque of a steering wheel of a host vehicle;
- receiving, from one or more perception sensors, an environment proximate the host vehicle;
- responsive to determining that the steering torque meets a first threshold, determining that an operator of the host vehicle requests a take-over from fully automated control of the host vehicle based on the steering sensor;
- responsive to determining that the operator of the host vehicle requests the take-over from fully automated control of the host vehicle, classifying, based on at least one of steering angle and steering angle rate or the environment proximate the host vehicle, the take-over as one of a plurality of take-over types;
- determining, based on the take-over type for the take-over and on the environment proximate the host vehicle, a level of automated driver assistance of the host vehicle;
- and
- operating the host vehicle according to the determined level of automated driver assistance.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processor of a host vehicle, cause the processor to:
- receive, from a steering sensor, a steering torque of a steering wheel of the host vehicle;
- receive, from one or more perception sensors, an environment proximate the host vehicle;
- responsive to a determination that the steering torque meets a first threshold, determine that an operator of the host vehicle requests a take-over from fully automated control of the host vehicle;
- responsive to the determination that the operator of the host vehicle requests the take-over from fully automated control of the host vehicle, classify, based on at least one of steering angle and steering angle rate or the environment proximate the host vehicle, the take-over as one of a plurality of take-over types;
- determine, based on the take-over type for the take-over and on the environment proximate the host vehicle, a level of automated driver assistance of the host vehicle;
- and
- operate the host vehicle according to the determined level of automated driver assistance.
