Abstract
(EN)
Provided is a vehicle power assist system by which rotary driving or regenerative braking of drive wheels or driven wheels is performed and with which it is possible to suppress the generation of heat in a motor generator. This vehicle power assist system comprises a DC power source (10), a motor generator (14), a control device (39) that controls the motor generator (14), and a temperature detection means (15). The motor generator (14) is supported by a vehicle-wheel bearing and generates drive assist force or regenerative braking force, the vehicle-wheel bearing rotatably supporting a vehicle wheel (5). The control device (39) comprises a power conversion circuit (12) that converts DC power from the DC power source (10) to AC power, and a control circuit (13) that controls the power conversion circuit (12). The temperature detection means (15) is positioned radially inward of a brake rotor and a brake caliper and radially outward of a stator of the motor generator (14), and detects the temperature produce by heat generated by the brake rotor, the brake caliper, and the stator. When the detected temperature exceeds a threshold value, the control circuit (13) limits the current flowing from the DC power source (10) to the motor generator (14).

La présente invention concerne un système d’assistance pour véhicule au moyen duquel un entraînement rotatif ou un freinage régénératif de roues motrices ou de roues entraînées est effectué et avec lequel il est possible de supprimer la génération de chaleur dans un moteur-générateur. Ce système d’assistance pour véhicule comprend une source d’alimentation CC (10), un moteur-générateur (14), un dispositif de commande (39) qui commande le moteur-générateur (14), et un moyen de détection de température (15). Le moteur-générateur (14) est soutenu par un roulement de roue de véhicule et génère une force d’assistance d’entraînement ou une force de freinage régénératif, le roulement de roue de véhicule soutenant de façon rotative une roue de véhicule (5). Le dispositif de commande (39) comprend un circuit de conversion d’électricité (12) qui convertit une électricité CC provenant de la source d’alimentation CC (10) en électricité CA, et un circuit de commande (13) qui commande le circuit de conversion d’électricité (12). Le moyen de détection de température (15) est positionné radialement vers l’intérieur d’un rotor de frein et d’un étrier de frein et radialement vers l’extérieur d’un stator du générateur de moteur (14), et détecte la température produite par la chaleur générée par le rotor de frein, l’étrier de frein et le stator. Lorsque la température détectée dépasse une valeur de seuil, le circuit de commande (13) limite le courant circulant de la source d’alimentation CC (10) vers le moteur-générateur (14).
