    • The invention relates to a method for managing the supply voltage (Vs) of an electronic computer (1) of an automobile, wherein the electronic computer (1) comprises: a microcontroller (4), a power supply circuit (3) powered by a voltage (V1) from a battery and supplying the controller (4) with a supply voltage (Vs) controlled by a controller (8) having a nominal control frequency (FREF) set by a clock (7); at least one electronic component (5) connected to the microcontroller (4) and connected to the power supply circuit (3) which supplies a controlled supply voltage (Vs) thereto; a means (9) for communication between the microcontroller (4) and the power supply circuit (3), characterized in that said method comprises the following steps: the identification, by the microcontroller (4), of an impending change in the usual demand (lD) of at least one electronic component (5); the transmission, by the microcontroller (4) and to the power supply circuit (3) via the communication means (9), of an instruction (S) for increasing the nominal control frequency (FREF) of the power supply circuit (3); the increase, by the power supply circuit (3), of the nominal control frequency (FREF) thereof to a higher control frequency (FACCEL) for a predetermined period of time (T) measured by the internal clock (7) of the power supply circuit (3); when the predetermined time period (T) has elapsed, the decrease, by the power supply circuit (3), of the higher control frequency(FACCEL) to the nominal control frequency (FREF) thereof.
    • 本发明涉及一种用于管理汽车电子计算机(1)的电源电压(Vs)的方法,其中电子计算机(1)包括:微控制器(4),由 从电池供给电压(V1)并向控制器(4)提供由具有由时钟(7)设置的标称控制频率(FREF)的控制器(8)控制的电源电压(Vs); 连接到微控制器(4)并且连接到向其提供受控供电电压(Vs)的电源电路(3)的至少一个电子部件(5) 一种用于在微控制器(4)和电源电路(3)之间通信的装置(9),其特征在于所述方法包括以下步骤:微控制器(4)识别通常需求即将发生变化 (1D)至少一个电子部件(5); 经由通信装置(9)由微控制器(4)和电源电路(3)传输用于增加电源电路(3)的标称控制频率(FREF)的指令(S); 由供电电路(3)将其额定控制频率(FREF)增加到较高的控制频率(FACCEL)一段预定时间段(T),由电源的内部时钟(7)测量 电路(3); 当经过预定时间段(T)时,由电源电路(3)将较高控制频率(FACCEL)降低到其额定控制频率(FREF)。
