Method and device for outputting driving information indicating an acceleration option that is optimal in terms of power consumption in a motor vehicle
First Claim
1. A method for outputting driving information to indicate a power consumption-optimized driving state to a driver of a motor vehicle, the method comprising:
- ascertaining, by a computer processor, a target value of an acceleration of the vehicle that is calculated to provide consumption that is optimal at conditions of at least one current operating state quantity of the vehicle and at least one tractive-resistance quantity;
ascertaining an actual vehicle acceleration by a transducer device;
generating the driving information as a function of the ascertained target vehicle acceleration and of the actual vehicle acceleration by the processor; and
determining, by the processor and based on the at least one tractive-resistance quantity, whether to output the driving information via an output device, the determining being performed according to a condition that the driving information is not output because of a value of the at least one tractive-resistance quantity, even where the actual vehicle acceleration deviates from the ascertained target value of the acceleration.
