determining a steering angle and a steering direction based on a radius and a rotational direction of the continuous rotary input; actuating a steering component of the vehicle based on the steering angle and the steering direction; and actuating a propulsion component of the vehicle based on detecting a speed of the continuous rotary input above a threshold. ### Claim 2 (depends on 1) The method of claim 1, further comprising, upon detecting the vehicle is stopped, displaying at least one of a gear selector and a speed selector on the touchscreen. ### Claim 3 (depends on 1) The method of claim 1, further comprising operating the vehicle at a vehicle speed based on the speed of the continuous rotary input. ### Claim 4 (depends on 1) The method of claim 1, further comprising operating the vehicle at a vehicle speed below an upper speed limit. ### Claim 5 (depends on 1) The method of claim 1, further comprising operating the vehicle at a vehicle speed below a lower speed limit based on detecting a trailer angle above a threshold. ### Claim 6 (depends on 1) The method of claim 1, further comprising actuating a brake component of the vehicle based on detecting the speed of the continuous rotary input below the threshold. ### Claim 7 (depends on 1) The method of claim 1, wherein the speed of the continuous rotary input is determined by one of an angular velocity and a tangential velocity. ### Claim 8 (depends on 1) The method of claim 1, further comprising operating the vehicle along a straight path based on one of detecting the steering angle below a radius threshold, detecting a button pressed on the portable device, and detecting a continuous non-rotary input. ### Claim 9 (depends on 1) The method of claim 1, further comprising displaying an indicator on the touchscreen based on the steering angle and the steering direction of the continuous rotary input. ### Claim 10 A system, comprising a computer including a processor and a memory, the memory storing instructions executable by the processor to: detect a continuous rotary input on a touchscreen of a portable device in communication with a vehicle; determine a steering angle and a steering direction based on a radius and a rotational direction of the continuous rotary input; actuate a steering component of the vehicle based on the steering angle and the steering direction; and actuate a propulsion component of the vehicle based on detecting a speed of the continuous rotary input above a threshold. ### Claim 11 (depends on 10) The system of claim 10, wherein the instructions further include instructions to, upon detecting the vehicle is stopped, display at least one of a gear selector and a speed selector on the touchscreen. ### Claim 12 (depends on 10) The system of claim 10, wherein the instructions further include instructions to operate the vehicle at a vehicle speed based on the speed of the continuous rotary input. ### Claim 13 (depends on 10) The system of claim 10, wherein the instructions further include instructions to operate the vehicle at a vehicle speed below an upper speed limit. ### Claim 14 (depends on 10) The system of claim 10, wherein the instructions further include instructions to operate the vehicle at a vehicle speed below a lower speed limit based on detecting a trailer angle above a threshold. ### Claim 15 (depends on 10) The system of claim 10, wherein the instructions further include instructions to actuate a brake component of the vehicle based on detecting the speed of the continuous rotary input below the threshold. ### Claim 16 (depends on 10) The system of claim 10, wherein the speed of the continuous rotary input is determined by one of an angular velocity and a tangential velocity. ### Claim 17 (depends on 10) The system of claim 10, wherein the instructions further include instructions to operate the vehicle along a straight path based on one of detecting the steering angle below a radius threshold, detecting a button pressed on the portable device, and detecting a continuous non-rotary input. ### Claim 18 (depends on 10) The system of claim 10, wherein the instructions further include instructions to display an indicator on the touchscreen based on the steering angle and the steering direction of the continuous rotary input. ### Claim 19 A system, comprising a computer including a processor and a memory, the memory storing instructions executable by the processor to: detect a continuous rotary input on a touchscreen of a portable device in communication with a vehicle; determine a steering angle and a steering direction based on a radius and a rotational direction of the continuous rotary input; actuate a steering component of the vehicle based on the steering angle and the steering direction; and operate the vehicle along a straight path based on one of detecting the steering angle below a radius threshold, detecting a button pressed on the portable device, and detecting a continuous non-rotary input.
