Method for assisting a driver in the driving of a motor vehicle

A method for assisting a driver with driving a motor vehicle, the method comprising:

• ascertaining, by a controller of the motor vehicle, a permissible driving speed in a route section that is presently driven or may be driven in a future by evaluating environmental data describing a motor vehicle environment;
• comparing, by the controller, a residual range of the motor vehicle to a distance from a predefined destination, the residual range determined based at least in part on a detected state of charge of an energy store of the motor vehicle or a detected fill level of a fuel tank of the motor vehicle, the distance from the predefined destination determined by a navigation device of the motor vehicle;
• ascertaining, by the controller, at least one of a predefined reduction amount or a predefined scaling factor as a function of at least a range surplus determined from the comparing, wherein the at least one of the predefined reduction amount or the predefined scaling factor is ascertained based at least in part on a distance of the range surplus being less than a first distance threshold and a driver type, the driver type being ascertained based at least in part on a statistical evaluation of a driving behavior of the driver;
• ascertaining, by the controller, at least one of a further reduction amount or a further scaling factor based at least in part on the distance of the range surplus being less than a second distance threshold;
• calculating, by the controller, a target maximum speed, which is lower than the permissible driving speed, by at least one of subtracting the predefined reduction amount and the further reduction amount from the permissible driving speed or multiplying the permissible driving speed by the further scaling factor;
• and
• instructing, by the controller, a longitudinally guiding driver assistance system of the motor vehicle to control a driving speed of the motor vehicle based at least in part on the target maximum speed, wherein the target maximum speed is used as a maximum speed or as a target speed.
