Proposal to allow the use of a haptic signal as an alternative to the current requirement for an acoustic signal for the corrective steering function, provided the vehicle is equipped with a lane-departure warning system approved under UN R130. The proposal also introduces a requirement that the haptic warning must extend beyond the steering wheel (e.g., the signal would also include the driver’s seat) in order to address misuse (i.e., hands off the steering wheel use).
