Abstract
A method performed by an intention indicating system of a vehicle, for indicating to a potential observer an ongoing or impending autonomous kinematic action of said vehicle, said method including: determining an ongoing or impending autonomous kinematic action of said vehicle; and performing a vertical vehicle motion representing said autonomous kinematic action, said vertical vehicle motion including raising and/or lowering a front portion and/or a rear portion of a vehicle body of said vehicle.
Claims15
A method performed by an intention indicating system of a vehicle, for indicating to a potential observer an ongoing or impending autonomous kinematic action of said vehicle, said method comprising:
- determining an ongoing or impending autonomous kinematic action of said vehicle;
- and
- performing a vertical vehicle motion representing said autonomous kinematic action, said vertical vehicle motion comprising raising and/or lowering a front portion and/or a rear portion of a vehicle body of said vehicle, wherein said vertical vehicle motion comprises:
- when said autonomous kinematic action comprises a transition from a standstill state to a shut down state, lowering said vehicle body front portion and rear portion from a nominal suspension level (N) to a lower suspension level (L);
- when said autonomous kinematic action comprises a transition from said shut down state to said standstill state, raising said vehicle body front portion and rear portion from said lower suspension level (L) to said nominal suspension level (N);
- when said autonomous kinematic action comprises an acceleration, raising said front portion and/or lowering said rear portion;
- and/or
- when said autonomous kinematic action comprises a deceleration, lowering said front portion and/or raising said rear portion.
An intention indicating system of a vehicle, adapted for indicating to a potential observer an ongoing or impending autonomous kinematic action of said vehicle, said intention indicating system comprising:
- an action determining unit adapted for determining an ongoing or impending autonomous kinematic action of said vehicle;
- and
- a vertical motion performing unit adapted for performing a vertical vehicle motion representing said autonomous kinematic action, said vertical vehicle motion comprising raising and/or lowering a front portion and/or a rear portion of a vehicle body of said vehicle, wherein said vertical vehicle motion comprises:
- when said autonomous kinematic action comprises a transition from a standstill state to a shut down state, lowering said vehicle body front portion and rear portion from a nominal suspension level (N) to a lower suspension level (L);
- when said autonomous kinematic action comprises a transition from said shut down state to said standstill state, raising said vehicle body front portion and rear portion from said lower suspension level (L) to said nominal suspension level (N);
- when said autonomous kinematic action comprises an acceleration, raising said front portion and/or lowering said rear portion;
- and/or
- when said autonomous kinematic action comprises a deceleration, lowering said front portion (and/or raising said rear portion.
