Method for attenuating interference in the measurement of a tilt angle of a vehicle

A method for attenuating interference in the measurement of an angle of sideways tilt of a motorized two-wheeled vehicle, said vehicle comprising an engine, an electronic control unit and a speed-measuring module, said electronic control unit comprising a tilt sensor and a memory region containing at least one predetermined attenuation interval, said electronic control unit being configured to compute the angle of sideways tilt of the vehicle from the measurements of the tilt sensor, to receive a value of the speed of the vehicle measured by the speed-measuring module and to receive the number of revolutions per minute of the engine, said method comprising of:

• reception, by the electronic control unit, of the value of the speed of the vehicle measured by the speed-measuring module,
• reception, by the electronic control unit, of the number of revolutions per minute made by the engine,
• computation, by the electronic control unit, of the ratio between the received speed value and the received number of revolutions per minute,
• comparison, by the electronic control unit, of the ratio between the received speed value and the number of revolutions per minute with the at least one predetermined attenuation interval,
• if the ratio between the received speed value and the number of revolutions per minute is outside the attenuation interval, computation, by the electronic control unit, of the tilt angle without attenuation,
• if the ratio between the received speed value and the engaged gear ratio is within the attenuation interval, computation by the electronic control unit, of the tilt angle with attenuation.
