Abstract
Road vehicle provided with an electric drive and having: at least one pair of drive wheels; at least one electric machine; a mechanical transmission that connects the electric machine to the drive wheels; a passenger compartment; at least one seat, which is housed in the passenger compartment and is provided with at least one mechanical exciter that is designed to generate mechanical vibrations at variable frequencies and intensities; and a control unit, which is designed to drive the mechanical exciter using a driving signal that derives from the noise generated by an internal combustion thermal engine and based on the speed of rotation of the electric machine and/or on the speed of rotation of the drive wheels and/or on the torque generated/absorbed by the electric machine.
Claims18
A road vehicle (1) provided with an electric drive (4);
- the road vehicle (1) comprises:
- at least one pair of drive wheels (3);
- at least one electric machine (8, 15), which is connected to the drive wheels (3);
- a passenger compartment (17);
- at least one seat (22), which is housed in the passenger compartment (17) and is provided with at least one mechanical exciter (26) configured to generate mechanical vibrations with variable frequency and intensity;
- and
- a control unit (27) configured to drive the at least one mechanical exciter (26) to generate the mechanical vibrations, wherein the variable frequency is dependent on a rotational speed of the electric machine (8;
- 15) and/or a rotational speed of the drive wheels (3) and wherein the intensity is dependent on torque generated and/or absorbed by the electric machine (8;
- 15).
