Autonomous vehicle and method for driving of autonomous vehicle on high-curvature curve

A method performed by an apparatus of a vehicle, the method comprising:

• starting a cruise control operation of the vehicle;
• determining that the vehicle is traveling on a high-curvature road having a curvature value above a threshold curvature value;
• determining, by an autonomous driving controller of the apparatus and based on a determination that the vehicle is traveling on the high-curvature road, that the vehicle is likely to depart from a driving lane in which the vehicle is traveling;
• determining, based on a determination that the vehicle is likely to depart from the driving lane, that driving control is required for the vehicle;
• and
• controlling, based on a determination that the driving control is required for the vehicle, an autonomous driving operation of the vehicle by inhibiting upshifting in a transmission of the vehicle.

A control device for a vehicle, the control device comprising:

• at least one sensor comprising an inertial measurement sensor and a camera;
• a processor;
• and
• a memory storing at least one instruction that is configured, when executed by the processor communicating with the memory, to cause the control device to:
• start a cruise control operation of the vehicle;
• determine, based on measurements of the inertial measurement sensor and at least one image captured by the camera, that the vehicle is traveling on a high-curvature road having a curvature value above a threshold curvature value;
• during an autonomous driving operation of the vehicle, determine, based on a determination that the vehicle is traveling on the high-curvature road, that the vehicle is likely to depart from a driving lane in which the vehicle is traveling;
• determine, based on a determination that the vehicle is likely to depart from the driving lane, that driving control is required for the vehicle;
• and
• control, based on a determination that the driving control is required for the vehicle, an autonomous driving operation of the vehicle by inhibiting upshifting in a transmission of the vehicle.
