ELECTRIC VEHICLE CONTROL DEVICE AND BRAKE CONTROLLING METHOD FOR ELECTRIC VEHICLE |
摘要 |
An electric vehicle control device includes a calculation unit that calculates a regenerative-brake-torque load factor when a braking command is detected. The calculation unit includes a brake-torque load-factor determination unit that determines the regenerative-brake-torque load factor according to vehicle speed information that is a detection value of vehicle speed; and a brake-torque load-factor correction unit that corrects the regenerative-brake-torque load factor determined by the brake-torque load-factor determination unit using element temperature information that is temperature information of a switching element included in an inverter. |

1. An electric vehicle control device comprising:
an inverter to drive a motor; a calculation unit to calculate a regenerative-brake-torque load factor when a braking command is detected; and an element-temperature detection unit to detect a temperature of a switching element included in the inverter, wherein the calculation unit includes a brake-torque load-factor determination unit to determine the regenerative-brake-torque load factor according to vehicle speed information as a detection value of a vehicle speed, and a brake-torque load-factor correction unit to correct a regenerative-brake-torque load factor determined by the brake-torque load-factor determination unit using element temperature information detected by the element-temperature detection unit. |
