Definitions
- said other sensors are suitable for sampling said measurements obtained from said associated rocket carriers at a frequency greater than or equal to 2000 Hz.
- an anti-aliasing filter costs in latency and signal delay.
- a better performance of the system is ensured by this unfiltered sampling. Indeed, a sufficient sampling frequency is obtained to guarantee robust consideration of the vibratory dynamics of rolling while having negligible aliasing of the spectrum for noise control up to 300 Hz.
- Figure 1 is a schematic view of a motor vehicle comprising an assembly according to the invention
- the trajectory control device 2 comprises in particular for each wheel 10, 10′ of the motor vehicle a wheel speed sensor 21, 21′, generally mounted on the stub axle carrier 20, 20′ of the corresponding wheel 10, 10′.
- Rolling noise is random and therefore makes it unpredictable unlike engine noise whose harmonics have a slower phase and amplitude evolution.
- the accelerations measured by the accelerometers 22, 22' are sampled at a relatively high frequency, preferably greater than 2000 Hz.
- a relatively high frequency preferably greater than 2000 Hz.
- this communication is optimized by the communication bus 5 by transmitting the unfiltered raw data.
- Each accelerometer 22, 22' being associated with three axes in this embodiment, and the vehicle comprising, in this embodiment, four wheels 10, 10', it is a total of 12 sampled signals to be transmitted between the device path control 2 and the anti-noise device 3.
- the anti-noise device 3 then implements a method comprising on the one hand the reception 201 of the sampled signals, the generation of an anti-noise signal 202, then the emission 203 of the anti-noise signal by the loudspeaker 31 in the passenger compartment.
