Embodiment Construction

[0020] In the following description of the figures, identical elements or functions are provided with the same reference symbols.

[0021] figure 1 A schematic diagram showing important components according to an embodiment of the present invention. Today's on-board electrical network of a vehicle 100 basically consists of a generator, one or more energy accumulators 1, 11 and different energy consumers 2, 3, 4, one of which is usually a lead-acid battery and the other The accumulator is an accumulator with a high power input capability such as a lithium-ion battery. The energy consumers 2 , 3 , 4 have been further developed from the beginning when only the starting system, the ignition system and the lighting system were already in operation. Today, a plurality of consumers 2 , 3 , 4 are installed in a vehicle 100 , which mostly carry out control, comfort and safety functions. Due to the plurality of energy consumers 2 , 3 , 4 , the power demand placed on the energy supply...

Abstract

The invention relates to a method for the situation-based adaptation of the charging strategy of energy stores of a vehicle having automatic start-stop functionality, comprising at least one energy store having high charge absorption capability, wherein, in a first step, a detection as to whether a current stop-and-go situation is present is carried out on the basis of predefined criteria during the current driving situation of the vehicle and, in a second step, if a current stop-and-go situation has been detected, intensified charging of the energy store is carried out during engine running between two automatically initiated engine-stop phases.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for adapting a charging strategy for an energy store of a vehicle to operating conditions. Background technique [0002] The on-board electrical system and its supply are at the heart of vehicle development during this period. Micro-hybrids have been in series for a long time and have the advantage that they have an automatic start-stop system—that is, the following electronic system—and a regenerative function (that is, recuperation of braking energy) for charging the starter battery (Charge: Laden), the electronic system shuts down the engine when the vehicle has been braked towards a stop and the driver keeps the brake pedal depressed (in vehicles with automatic transmission), and when the driver removes his foot from the brake The electronic system then switches the engine back on. Fuel can be saved through this technology. Micro-hybrids can use their accumulators instead of ...
