Title (EN) EXTERNAL WATCHDOG WITH INTEGRATED BACKWARD REGENERATION SUPPORT
(FR) DISPOSITIF DE SURVEILLANCE EXTERNE À SUPPORT DE RÉGÉNÉRATION ARRIÈRE INTÉGRÉ
Abstract:
(EN) The present invention relates to an electric power steering apparatus for assisting steering of a motor vehicle by conferring torque generated by an electric motor to a steering mechanism, the apparatus comprising: • a steering controller, which receives signals representative of at least the torque applied to a steering wheel and determining a target motor torque, with a microcontroller MCU and a watchdog WD; • a motor controller comprising an inverter which transforms from target motor toque generated target voltages into motor currents, wherein the watchdog WD comprises a memory in which state variables of the MCU are stored and a timer which monitors a blackout time of the MCU, wherein the MCU and the watchdog are linked via a communication bus and a reset line.
(FR) La présente invention concerne un appareil de direction assistée électrique qui permet d'assister la direction d'un véhicule automobile en conférant un couple généré par un moteur électrique à un mécanisme de direction et qui comprend : • un dispositif de commande de direction, qui reçoit des signaux représentant au moins le couple appliqué à un volant de direction et la détermination d'un couple moteur cible, ayant un microcontrôleur (MCU) et un dispositif de surveillance (WD) ; • un dispositif de commande de moteur comprenant un onduleur qui transforme des tensions cibles, générées par un couple moteur cible, en courants de moteur, le dispositif de surveillance (WD) comprenant une mémoire dans laquelle des variables d'état du MCU sont stockées et un minuteur qui surveille un temps de coupure du MCU, le MCU et le dispositif de surveillance étant reliés par l'intermédiaire d'un bus de communication et d'une ligne de réinitialisation.
