Abstract:
1. A method for optimized starting of an internal combustion engine with a starter, which is connected to a capacitor store, the capacitor store connected via a first DC/DC converter to a vehicle electrical system of a vehicle, the vehicle electrical system including an energy store for supplying electrical energy having a nominal voltage, and the starter consuming a starting energy for starting the internal combustion engine, which is a function of a temperature of the internal combustion engine, comprising: measuring the temperature of the internal combustion engine by at least one temperature sensor; charging the capacitor store to a setpoint voltage by a battery via a second DC/DC converter, which connects the battery in parallel to the capacitor store parallel to a switch; setting the setpoint voltage by a control device such that the electrical energy stored in the capacitor store charged to the setpoint voltage is greater than the starting energy ascertained on the basis of the measured temperature.
