A recently granted patent (Publication Number: US11866117B2) discloses a vehicle equipped with an electric motor, a wheel drivably connected to the motor for propulsion, and controls for drive torque and regenerative braking. An electronic control unit is configured to detect the positions of these controls, map them to requested driving and braking torques, and transmit a torque command to the electric motor. The system allows for efficient control of the vehicle's propulsion and braking mechanisms, with regenerative braking being the sole braking mechanism for the wheel.

The patent also describes a method and system for operating the electric motor of the vehicle, involving detecting the positions of controls, mapping them to requested torques, and determining a torque command based on these inputs. The electronic control unit plays a crucial role in calculating the torque command, which can be done by summing or multiplying the requested torques. This innovative system ensures precise control over the vehicle's propulsion and braking functions, with regenerative braking being the primary mechanism for slowing down the wheel. Overall, the patent highlights a sophisticated approach to managing the performance of electric vehicles, enhancing efficiency and control for a smoother driving experience.
