摘要:
The present invention relates to a method for adjusting the acceleration of a vehicle travelling along a route, comprising the steps of continuously detecting the presence of speed-limiting features along the vehicle's route and, when speed-limiting features are detected, of determining the acceleration required for reaching a prescribed target speed at such a detected coming speed-limiting feature. The method is characterised by the step of detecting the presence of external road users along the vehicle's route, involving determination of characteristics of such external road users, comprising vehicles behind, vehicles in front and/or lateral positions of such external road users, and the step of determining required acceleration involves the step of determining braking strategy taking the presence of such detected external road users into account. The present invention relates also to a system for adjusting the acceleration of a vehicle travelling along a route. The present invention relates also to a motor vehicle. The present invention also relates to a computer programme and a computer programme product.

摘要:
The present invention concerns a method for adapting the velocity of a vehicle during driving of the vehicle along a route of travel, comprising the steps of: prescribing (S1 ) velocity in the form of a velocity profile comprising retardations along the route of travel of the vehicle based on the occurrence of velocity-limiting factors along the route of travel of the vehicle. The method comprises the step of prescribing (S2) a target velocity associated with a velocity-limiting factor. The method further comprises the step of controlling (S3) the vehicle velocity so that a velocity associated with said target velocity is permitted to be higher than the target velocity by a given offset, wherein said offset is adapted so that a relatively larger offset is permitted in connection with a non-safety-critical velocity-limiting factor and a relatively smaller offset is permitted in connection with a safety-critical velocity-limiting factor. The present invention also concerns a system for adapting the velocity of a vehicle during driving of the vehicle along a route of travel. The present invention also concerns a motor vehicle. The present invention also concerns a computer program and a computer program product.

The present invention relates to a method to assess (S1) the risk of change of traffic lane during the driving of a vehicle on a roadway with at least two neighbouring traffic lanes, comprising the step: to detect (S2) the presence of objects in traffic lanes neighbouring to the traffic lane in which the said vehicle is being driven, comprising the steps: to determine, based on specifications concerning the extent of a defined traffic lane in which the vehicle is being driven, the extent of at least one neighbouring traffic lane based on continuously determined reference positions at the vehicle relative to the said neighbouring traffic lane, in order to determine an action zone extending a specified extent in the said neighbouring traffic lane alongside the said vehicle, and, in the event of the presence of objects in the said action zone, to take measures (S3) in association with the change of traffic lane. The present invention relates also to a system to assess the risk of change of traffic lane during the driving of a vehicle on a roadway with at least two neighbouring traffic lanes, and a motor vehicle comprising such a system. The present invention relates also to a computer program and a computer program product.

Method and control unit for predicting a path of a vehicle are provided. The method comprises measuring velocity of the vehicle; measuring steering wheel angle (αsw); measuring steering wheel angle rate (α′sw); calculating a future steering wheel angle (αsw), based on the measured steering wheel angle (αsw) and the measured steering wheel angle rate (α′sw); calculating a future yaw rate (ω) of the vehicle based on the measured velocity of the vehicle and the calculated future steering wheel angle (αsw); extrapolating a vehicle position of the vehicle in a set of future time frames, based on the calculated future yaw rate (ω) and the vehicle velocity; and predicting the path of the vehicle based on the extrapolated vehicle positions in the set of future time frames.

The present invention relates to a method for the adaptation of the speed of a vehicle when taking a curve. The method comprises the step to control (S1 ) the speed of the vehicle and in this case limit the increase of a maximum permitted instantaneous speed based on the rate of change of angle of the steering wheel position in such a manner that the increase to a determined extent is allowed only when the rate of change of angle has fallen below a predetermined value. The present invention relates also to a system for the adaptation of the speed of a vehicle when taking a curve. The present invention relates also to a motor vehicle. The present invention relates also to a computer program and a computer program product.
