A method for managing the power supply voltage (Vs) of an electronic computer of a motor vehicle, the electronic computer including: a microcontroller, a power supply circuit powered by a battery and supplying the microcontroller with a power supply voltage regulated by a regulator having a nominal regulation frequency (FREF) set by a clock, at least one electronic component connected to the microcontroller and the power supply circuit which supplies it with a regulated power supply voltage, a element of communication between the microcontroller and the power supply circuit, the method includes: identification of an imminent modification of the current demand, sending an instruction to increase the FREF, increasing its FREF to a higher regulation frequency (FACCEL), for a predetermined time period (T) measured by the internal clock, when T has elapsed, lowering the higher regulation frequency (FACCEL) to its nominal regulation frequency (FREF).
