Abstract
A vehicle having a motor with a transmission, provided with a fixed gear ratio, to a propelling unit includes a virtual gearbox including a microprocessor, operatively interfaced with the motor and programmed to manage and check the generation of motor driving torque, limiting, at the motor output, a maximum angular velocity and a maximum torque which are variable with a predetermined law.
Claims20
A method comprising:
- programming a microprocessor to emulate a virtual gearbox of a vehicle, wherein the programming comprises setting limits of a maximum angular velocity and a maximum torque according to a predetermined rule, wherein the predetermined rule is set according to a speed of the vehicle;
- providing, by an electric motor, an angular velocity and a torque to a transmission with a fixed gear ratio;
- and
- limiting, using the microprocessor, the angular velocity and the torque of the electric motor according to the maximum angular velocity, the maximum torque, and the speed of the vehicle, wherein the virtual gearbox simulates a plurality of gear ratios of a mechanical gearbox.
