COMPUTER SYSTEM COMPRISING PROCESSING CIRCUITRY CONFIGURED TO CONTROL PROPULSION OF A VEHICLE

A computer system has processing circuitry to control propulsion of a vehicle. The vehicle has a power unit to propel the vehicle and an accelerator pedal. The processing circuitry is configured to: obtain information indicative of a position of the accelerator pedal, control propulsion of the power unit based on the information indicative of the position of the accelerator pedal; and control the power unit in either a torque control mode or a speed control mode. In the torque control mode, the information indicative of the position of the accelerator pedal is indicative of a target torque of the power unit and the power unit is controlled based on the target torque of the power unit. In the speed control mode, the information indicative of the position of the accelerator pedal is indicative of a target speed and the power unit is controlled based on the target speed. The processing circuitry is configured to, in the torque control mode with the accelerator pedal depressed: determine an instant that an acceleration phase of the vehicle is complete, and in response thereto, switch control from the torque control mode to the speed control mode.
