摘要:
The present invention relates to a slope feedback device for determining and presenting feedback to a driver of a vehicle, comprising a slope determining unit adapted to determine a slope profile of a slope passed by the vehicle, based upon output signals from a slope profile sensing means and driving sensing means to continuously sense and calculate a driver's driving activity during passage of a slope. The driving sensing means in addition continuously calculates a driving resistance force F res and a specific driving resistance point F res ≤o is determined, where the driving resistance force F res is less or equal to zero. The slope determining unit is further adapted to calculate for each F res ≤o a slope balance point P bal defined as the theoretical point where the gas should be released in order to balance consumed energy, by the vehicle, before said F res≤o and gained energy, by the vehicle, after said point, and to determine an optimal driving activity in dependence of P bal . The device further comprises a driving ability calculating means adapted to match the driving activity to the determined slope profile, and to generate a grade in dependence of how well the driving activity coincides with the optimal driving activity. The grade is further presented to the driver of the vehicle.

The present invention concerns a method for adapting the acceleration of a vehicle (1 ) during driving of the vehicle along a route of travel. The method comprises the steps of: continuously determining (S1 ) the occurrence of velocity-limiting factors along the route of travel of the vehicle; and, in connection with the determination of a velocity-limiting factor, prescribing (S1 a) a velocity based on occurring velocity-limiting factors and determining (S2) the acceleration required to achieve the prescribed velocity at an occurring velocity-limiting factor. The step of determining the acceleration required to achieve the prescribed velocity at the occurring velocity-limiting factor comprises the step of continuously determining the driving resistance along the route of travel of the vehicle. The present invention also concerns a system. 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 for the adaptation of the driving of a vehicle on a roadway in association with taking a curve. The method comprises the steps to determine (S1 ) the degree of curvature along the route of the vehicle and to adapt (S2) the speed of the vehicle based on the lateral acceleration of the vehicle. The method comprises further the steps to determine (S3) a maximum permitted lateral acceleration; and to adapt (S4) the maximum permitted lateral acceleration depending on properties of the vehicle and/or the surroundings that influence the safe driving of the vehicle when taking a curve. The step to adapt the maximum permitted lateral acceleration includes the step to determine a factor that corresponds to the degree to which the said properties of the vehicle and/or the surroundings influence safe driving of the vehicle when taking the curve, whereby the said factor includes the influence of properties of the surroundings in the form of the effective width of the traffic lane in which the vehicle is being driven. The present invention relates also to a system for the adaptation of the driving of a vehicle on a roadway in association with 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.

The present invention relates to a method for the adaptation of the driving of a vehicle on a roadway in association with taking a curve. The method comprises the steps: to determine continuously (S1) the current lateral acceleration of the vehicle; to compare (S2), based on a maximum permitted lateral acceleration of the vehicle that has been determined, the current lateral acceleration with the maximum permitted lateral acceleration; and, in the case in which the current lateral acceleration lies below the maximum permitted lateral acceleration, to apply (S3) an automatic limitation of the longitudinal acceleration of the vehicle and/or the speed of the vehicle, in order to avoid that the current lateral acceleration exceeds the maximum permitted lateral acceleration. The present invention relates also to a system for the adaptation of the driving of a vehicle on a roadway in association with 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.

Method and control unit, for avoiding a potential collision between the vehicle and a Vulnerable Road User, VRU. The method comprises: predicting a future path of the vehicle; detecting the VRU and the position of the VRU; determining velocity of the detected VRU; predicting a future position of the detected VRU, based on the VRU position upon detection and the determined VRU velocity; and performing an action for avoiding a collision, when the predicted future position of the VRU is overlapping the predicted future path of the vehicle.
