Proposal to allow the use of the flashing electronic stability control (ESC) tell-tale to indicate the intervention of a corrective steering function (CSF) in cases where the CSF is controlled by the ESC (or other vehicle stability function) system. Outside such cases, CSF interventions are indicated by a continuous optical signal displayed for the duration of the intervention.

Proposal to resolve measurement concerns in the test requirements for ACSF of Category B1 and C by introducing provisions for tolerances, including:

1. inclusion of the position at which the lateral acceleration was measured and the position of the centre of gravity of the vehicle for better traceablility,
2. sampling rate of at least 100 Hz for dynamic testing,
3. specification of filters and cut-off frequency for determination of lateral acceleration,
4. option to measure “overriding force” torque via an internal sensor or an external device (e.g., steering robot).

The proposal also would modify the high-speed test to end once the system has given an optical “hands-off” warning since the entire warning cascade is checked during the low-speed test. For M₂ and M₃ vehicles, the amendment allows a corrective steering function to use haptic signals as an alternative to acoustic signals for these categories of vehicles that are equipped with Lane Departure Warning System compliant with UN R130. This change would specify that the haptic warning may not be given solely via the steering wheel (e.g., provided in the driver’s seat).

Proposal from GRVA to allow continuous movement of the driver as an alternative to the continuous actuation of the remote-control device as a means to assure driver attentiveness.
