There is provided a solar battery control apparatus comprising: a solar battery in a vehicle; a vehicle speed detecting unit; a load circuit capable of be controlled to vary a generated current; and a control unit configured to perform MPPT control while controlling the load circuit to vary the generated current, wherein the control unit varies the generated current within a range having a certain upper limit value upon the speed of the vehicle being detected to be greater than a predetermined speed. The predetermined speed is set to be less than a speed at which the generated current becomes unable to be varied to correspond to a change in an i-V output characteristic of the solar battery, and the certain upper limit value is set to be less than a value of short-circuiting current having been reduced according to the change.

Die Erfindung betrifft ein Verfahren zum Betreiben eines Kraftfahrzeugs (10), bei welchem wenigstens eine zum Antreiben des Kraftfahrzeugs (10) ausgebildete elektrische Maschine (12, 14) zum Rekuperieren von elektrischer Energie genutzt wird. Hierbei wird eine Fahrt des Kraftfahrzeugs (10) während eines bevorstehenden Zeitraums berücksichtigt. Beim Nutzen der wenigstens einen elektrischen Maschine (12, 14) zum Rekuperieren der elektrischen Energie wird berücksichtigt, ob aufgrund einer thermischen Belastung der wenigstens einen elektrischen Maschine (12, 14) in dem Zeitraum eine Verringerung der von der wenigstens einen elektrischen Maschine (12, 14) abgebbaren Leistung zu erwarten ist. Dann rekuperiert die wenigstens eine elektrische Maschine (12, 14) während eines Verzögerns des Kraftfahrzeugs (10) eine Menge an elektrischer Energie, welche geringer ist als die während des Verzögerns mittels der wenigstens einen elektrischen Maschine (12, 14) rekuperierbare Menge an elektrischer Energie. Des Weiteren betrifft die Erfindung ein Kraftfahrzeug (10).
摘要:
The invention relates to a method for calculating a setpoint for managing the fuel and electricity consumption of a hybrid motor vehicle. According to the invention, the method comprises steps of: a) acquiring, by means of a navigation system on board the hybrid motor vehicle, a route to be travelled; b) dividing said route into consecutive portions; c) assigning attributes that characterise each portion; d) determining, for each of said portions, a curve or a map that links each fuel consumption value of the hybrid motor vehicle over the portion to a charge or discharge value of the traction battery; e) determining an optimal point of each curve or map, which makes it possible to minimise the fuel consumption of the hybrid motor vehicle over the entire route and to completely discharge the traction battery by the end of said route; and f) producing an energy management setpoint in accordance with the coordinates of said optimal points.

A target power value determining unit (200) determines target power values Pc1* and Pc2* such that a sum £Pc* of target load powers as a sum of target load power Pc1* and target load power Pc2* does not exceed a sum £Win of allowable charging powers and a sum £Wout of allowable discharging powers. In accordance with the generated target load power values Pc1* and Pc2*, switching commands PWM1 and PWM2 are generated. Consequently, an inverter executes a power conversion operation such that the powers exchanged between a main line ML and motor generators attain to the target load power values Pc1* and Pc2*, respectively.
