Abstract

See full text

A method of controlling a solenoid valve of an automotive system, the valve being charged by a pulse width modulated signal (PWM) and determining an actuation of an automotive system component is provided. The method comprises the following: determining a target end of command of the valve as a function of a PWM state and a time interval from a last change of PWM state; monitoring a current value, a PWM phase period and the PWM state of a last pulse width modulated signal; and correcting in the next pulse width modulated signal at least one of said current value and PWM phase period, so that a next end of command of the valve will occur at the target end of command.
