Abstract
System, methods, and other embodiments described herein relate to stabilizing a vehicle. In one embodiment, a method for stabilizing a vehicle with a drivetrain having a clutch includes obtaining data indicating one or more aspects of a turning condition of the vehicle, detecting that a hazard state exists based on a comparison of one or more parameters of the turning condition against one or more predetermined thresholds, and executing a clutch kick in response to detecting the hazard state. The clutch kick includes disengaging the clutch and rapidly reengaging the clutch.
Claims17
A stabilization system for a vehicle having a clutch, comprising:
- a sensor configured to generate sensor data indicating one or more aspects of a turning condition of the vehicle in an environment of the vehicle;
- a processor;
- and
- a memory, communicably connected to the one or more processors, storing:
- a detection module including instructions that, when executed by the processor, cause the processor to detect a turning condition of the vehicle based at least in part on the sensor data and determine that a hazard state exists based on a comparison of one or more parameters of the turning condition against one or more predetermined thresholds, and
- a clutch kick module including instructions that, when executed by the processor, cause the processor to execute a clutch kick in response to the hazard state, wherein the clutch kick comprises disengaging the clutch and rapidly reengaging the clutch and actuating a gear up-shift while the clutch is disengaged.

- a processor;
- and
- a memory, communicably connected to the one or more processors, storing:
- a detection module including instructions that, when executed by the processor, cause the processor to detect a turning condition of the vehicle based at least in part on the sensor data and determine that a hazard state exists based on a comparison of one or more parameters of the turning condition against one or more predetermined thresholds, wherein the hazard state comprises a projected trajectory of the vehicle intersecting an obstacle, and
- a clutch kick module including instructions that, when executed by the processor, cause the processor to execute a clutch kick in response to the hazard state, wherein the clutch kick comprises disengaging the clutch and rapidly reengaging the clutch.
A method for controlling a vehicle with a drivetrain having a clutch, comprising:
- obtaining data indicating one or more aspects of a turning condition of the vehicle;
- detecting that a hazard state exists based on a comparison of one or more parameters of the turning condition against one or more predetermined thresholds;
- and
- executing a clutch kick in response to detecting the hazard state;
- wherein the clutch kick comprises disengaging the clutch and rapidly reengaging the clutch and actuating a gear up-shift while the clutch is disengaged.

- detect that a hazard state exists based on a comparison of one or more parameters of the turning condition against one or more predetermined thresholds;
- and
- execute a clutch kick in response to detecting the hazard state;
- wherein the clutch kick comprises disengaging the clutch and rapidly reengaging the clutch and actuating a gear up-shift while the clutch is disengaged.
