Adaptive driving system

A vehicle system for a host vehicle traveling in a driving lane with an object adjacent to the driving lane, the vehicle system comprising:

• a set of sensors being configured to detect a position and a speed of the host vehicle within the driving lane, and to detect a position and a speed of the object adjacent to the driving lane;
• and
• a control system configured to determine an operational state based on input from the sensors, to operate the host vehicle in an autonomous mode wherein the control system controls the speed of the host vehicle and a spacing between the host vehicle and the object, and to switch from the autonomous mode to a learning mode in response to the driver taking control of the speed or steering of the host vehicle;
• wherein when in the learning mode, the control system learns a preferred spacing between the host vehicle and the object and a preferred speed of the host vehicle relative to the object;
• wherein the control system is configured to control the host vehicle in the autonomous mode based on the preferred spacing and preferred speed during similar operational states;
• and
• wherein the control system is configured to store multiple overtaking policies for a particular operational state and to prompt the driver to choose a preferred overtaking policy from a list including the multiple overtaking policies.

A method of controlling a host vehicle traveling in a driving lane with an object adjacent to the driving lane, the method comprising:

• detecting a first operational state including a position and speed of the host vehicle relative to the object;
• determining a planned overtaking policy based on the first operational state;
• operating the host vehicle in an autonomous mode according to the planned overtaking policy;
• operating the host vehicle in a learning mode in response to a driver taking over control during the autonomous mode;
• storing an actual overtaking policy based on the first operational state and input from the driver during the learning mode;
• and
• operating the host vehicle in the autonomous mode based on the actual overtaking policy in response to the vehicle encountering operational states similar to the first operational state;
• and
• prompting the driver to select a preferred overtaking policy from a selection of overtaking policies corresponding to the first operational state.

A method of controlling a host vehicle traveling in a driving lane, the method comprising:

• detecting a first operational state that includes a lateral spacing of the host vehicle relative to an object adjacent to the driving lane, a speed of the host vehicle relative to the object, and a size or a type of the object;
• determining a planned overtaking policy for overtaking the object, the planned overtaking policy including a planned lateral spacing and a planned speed of the host vehicle relative to the object;
• operating the host vehicle in an autonomous mode according to the planned overtaking policy;
• detecting an actual overtaking policy based on manual input by a driver during the autonomous mode, the actual overtaking policy including an actual lateral spacing and an actual speed of the host vehicle relative to the object;
• storing the actual overtaking policy in a database of overtaking policies;
• and
• operating the host vehicle in the autonomous mode according to a preferred overtaking policy that is based on the actual overtaking policy in response to the host vehicle encountering a second operational state that is similar to the first operational state;
• and
• prompting the driver to select the preferred overtaking policy from a selection of overtaking policies.
