Method and device for assisting a vehicle operator
First Claim
1. A method for assisting an operator of a vehicle which is approaching a set of traffic lights which permits a stop line to be crossed in at least one first operating state and does not permit the stop line to be crossed in a second operating state, the method comprising:
- receiving, by a processor in the vehicle, a signal which describes a current operating state of the set of traffic lights and a time period until the operating state changes,verifying, by the processor, whether the vehicle can reach the stop line at a speed from a predefined speed range while the set of traffic lights is in the first operating state based on the received signal, andcontrolling, by the processor, a speed of the vehicle based on a result of the verification as long as a measured distance between the vehicle and an object located in front of the vehicle is greater than or equal to a threshold value,wherein the speed of the vehicle is controlled to maintain a predefined distance between the vehicle and the object located in front of the vehicle when the measured distance is less than the threshold value.

Abstract
A method for assisting an operator of a vehicle which is approaching a set of traffic lights which permits a stop line to be crossed in at least one first operating state and does not permit the stop line to be crossed in a second operating state. The method provides that (i) a signal which describes the current operating state of traffic lights and the time period until the operating state changes is received in the vehicle, (ii) in the vehicle, verification is carried out on the basis of the received signal as to whether the vehicle can reach the stop line at a speed from a predefined speed range while the set of traffic lights is in the first operating state, and (iii) a speed of the vehicle is influenced and/or a recommendation for influencing the speed is generated as a function of the result of the verification.

14. A system for assisting an operator of a vehicle which is approaching a set of traffic lights which permits a stop line to be crossed in at least one first operating state, and does not permit the stop line to be crossed in a second operating state, said system comprising:
-
a communication interface which is configured to receive a signal which describes a current operating state of the set of traffic lights and a time period until the operating state changes, an evaluation unit which is configured to verify, on a basis of the received signal, whether the vehicle can reach the stop line at a speed from a predefined speed range while the set of traffic lights is in the first operating state, and a control unit which is configured to influence a speed of the vehicle and/or to control generation of a recommendation for influencing the speed as a function of a result of the verification as long as a measured distance between the vehicle and an object located in front of the vehicle is greater than or equal to a threshold value, wherein the speed of the vehicle is controlled to maintain a predefined distance between the vehicle and the object located in front of the vehicle when the measured distance is less than the threshold value.
