Method and device for controlling a velocity of a motor vehicle
DCFirst Claim
1. A method for adjusting a velocity of a motor vehicle to a programmable target velocity, comprising the steps of:
- measuring an instantaneous velocity of the motor vehicle;
measuring, using a distance sensor, at least one distance from the motor vehicle to an object which is in front of the motor vehicle, the object being one of a further vehicle and an obstacle;
accelerating or decelerating the motor vehicle as a function of at least the measured at least one distance and the measured instantaneous velocity; and
if a blinding sensor determines that a driver of the motor vehicle is blinded by a light of oncoming traffic, performing one of the following;
reducing or eliminating a positive acceleration of the motor vehicle, andreducing the instantaneous velocity of the motor vehicle.

Abstract
A method and a device for adjusting the velocity of a motor vehicle to a programmable target velocity, with a current velocity of the controlled vehicle being measured. A distance sensor measures at least one distance to a vehicle or another obstacle in front of the controlled vehicle. The controlled vehicle is accelerated or decelerated as a function of at least the measured distance and the measured instantaneous velocity. A positive acceleration of the controlled vehicle ceases or is reduced, or the instantaneous velocity of the controlled vehicle is reduced, if a blinding sensor is used to determine that the driver of the controlled vehicle is being blinded by the light of oncoming traffic.
