Title (EN) SELECTING PARTICULAR TRANSISTORS IN AN ELECTRIC VEHICLE TO BE ACTIVATED/DEACTIVATED IN RESPONSE TO CURRENT CONDITIONS TO IMPROVE MILEAGE AND RESPONSE OF ELECTRIC VEHICLE
(FR) SÉLECTION, DANS UN VÉHICULE ÉLECTRIQUE, DE TRANSISTORS PARTICULIERS À ACTIVER/DÉSACTIVER EN RÉPONSE À DES CONDITIONS COURANTES POUR AMÉLIORER LE KILOMÉTRAGE ET LA RÉPONSE DU VÉHICULE ÉLECTRIQUE
Abstract:
(EN) A method, system and computer program product for optimizing the performance of an electric vehicle. An electronic controller controlling the operation of hub motors monitors the temperature of transistors in the electric vehicle, monitors the speed of the electric vehicle and monitors the rate at which an accelerator pedal is pressed. Furthermore, the electronic controller searches a look-up table containing the characteristics (e.g., switching characteristics) of the transistors. The electronic controller then determines whether there should be a change in the particular transistors that are activated/deactivated based on the temperature of the transistors, the speed of the electric vehicle, the rate at which the accelerator pedal is pressed and the characteristics of the transistors. In this manner, the performance of the electric vehicle is optimized since the transistors that are currently activated are those that would be most efficient to operate at that moment based on the current operating condition.
(FR) La présente invention concerne un procédé, un système et un programme d'ordinateur pour optimiser les performances d'un véhicule électrique. Un contrôleur électronique commandant le fonctionnement de moteurs d'élévation surveille la température de transistors dans le véhicule électrique, surveille la vitesse du véhicule électrique et surveille la cadence à laquelle une pédale d'accélérateur est enfoncée. Par ailleurs, le contrôleur électronique recherche dans une table de correspondance contenant les caractéristiques (par ex., caractéristiques de commutation) des transistors. Le contrôleur électronique détermine ensuite s'il doit y avoir un changement parmi les transistors particuliers qui sont activés/désactivés sur la base de la température des transistors, de la vitesse du véhicule électrique, de la cadence à laquelle la pédale d'accélérateur est enfoncée et des caractéristiques des transistors. De cette manière, les performances du véhicule électrique sont optimisées puisque les transistors qui sont couramment activés sont ceux qui seraient les plus efficaces pour fonctionner à ce moment sur la base de la condition courante de fonctionnement.
