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.
Claims7
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, and
- reducing the instantaneous velocity of the motor vehicle.
A device for controlling a velocity of a motor vehicle, comprising:
- a distance sensor determining at least one distance between the motor vehicle and an object in front of the motor vehicle, the object being one of a further vehicle and an obstacle;
- a velocity measuring arrangement measuring an instantaneous velocity of the motor vehicle;
- a control unit determining at least one control quantity as a function of the measured at least one distance and the measured instantaneous velocity;
- a plurality of actuators controlling at least one of a motor controller functional unit, a transmission controller functional unit and a brake controller functional unit as a function of the at least one control quantity;
- a blinding detection arrangement detecting a driver blinding condition for a driver of the motor vehicle;
- and
- a controlling arrangement performing one of the following:
- preventing or reducing an acceleration of the motor vehicle, and
- reducing the instantaneous velocity of the motor vehicle as a function of the driver blinding condition.
