Gap indicator for the changing of lanes by a motor vehicle on a multilane road
First Claim
Patent Images
1. A gap indicator for a changing of lanes by a first motor vehicle on a multilane road, comprising:
- a surround sensor system for recording a traffic surround field including traffic in at least one adjacent lane, the surround sensor system including a distance measuring instrument, a length measuring instrument and a velocity measuring instrument for all other motor vehicles to the rear and to the side, detected within a limited distance range starting from the first motor vehicle, in the at least one adjacent lane; and
an identification device for determining gaps in the traffic sufficient for a lane change, wherein, by comparing parameters of a velocity of the first motor vehicle and velocities of the other motor vehicles and their distances from the first motor vehicle to setpoint values from a set including velocity, accelerating ability, driver-reaction time and gap size, the identification device predictively ascertains a coming gap sufficient for a lane change and outputs acceleration commands to an engine or deceleration commands to a brake system with the aid of a control device, or outputs detailed driving instructions to a driver of the first motor vehicle with the aid of a dialog device.
