Abstract

Un dispositif de commande de moteur embarqué sur un véhicule (1) comprend un circuit de commutation de puissance (7) disposé sur une carte de circuit (10) pour fournir du courant d'une batterie (12) à un moteur (13), un microcalculateur (2) disposé sur la même carte de circuit (10) qui commande le circuit de commutation de puissance (7) dans un mode de commande à modulation PWM pour minimiser la différence entre le courant fourni au moteur (13) et un courant préétabli. Le microcalculateur (2) diminue le courant préétabli lorsque la tension de batterie est plus élevée qu'une limite supérieure ou lorsqu'à la fois la tension de batterie et la tension d'un signal IG sont plus élevées que des limites supérieures respectives.A vehicle-mounted engine control device (1) comprises a power switching circuit (7) provided on a circuit board (10) for supplying current from a battery (12) to an engine (13), a microcomputer (2) disposed on the same circuit board (10) which controls the power switching circuit (7) in a PWM modulation control mode to minimize the difference between the current supplied to the motor (13) and a current pre-established. The microcomputer (2) decreases the preset current when the battery voltage is higher than an upper limit or when both the battery voltage and the voltage of an IG signal are higher than respective upper limits.
