摘要: An electrically driven vehicle equipped with electric motors (1, 4) for driving or braking drive wheels (3, 6), and an electric motor controller (33) for controlling the electric motors includes: wheel speed detectors (9 to 12) for detecting the wheel speed of the drive wheels and that of idler wheels (7, 8); computing means (22 to 28, 35 to 38) for computing the slip ratio of the drive wheels based on the wheel speed of the drive wheels and that of the idler wheels; and a determiner (29) for determining that the drive wheels are slipping if the slip ratio exceeds a slip ratio determination value. If the wheel speed of the idler wheels is lower than set speeds Va2, Vb2, then the determiner (29) changes the slip ratio determination value to a value having as the same sign as, and a larger absolute value than, the values λa2, λb2 used when the wheel speed of the idler wheels is higher than the set speeds Va2, Vb2. This structure shortens acceleration time during acceleration traveling and reduces braking distance during deceleration traveling while inhibiting vibrations of the electrically driven vehicle.

摘要: Disclosed is a driving force control device that includes a determination section (12), a driving force command value calculation section (13), and a command value output section (14). The determination section (12) determines whether each of a plurality of motors (106), which independently drive a plurality of wheels (107), can be operated within a desired operating range when driven by a target driving force calculated for each of the motors (106). The driving force command value calculation section (13) adjusts the distribution of driving force for each of the motors in accordance with the target driving force for each of the motors and with the operating status of each of the motors and calculates an actual driving force command value for each of the motors for the purpose of operating each of the motors within the desired operating range if the determination means determines that each of the motors cannot be operated within the desired operating range. The command value output section (14) outputs the driving force command value to each of a plurality of inverters (105). Therefore, a target vehicle motion can be maximally realized while appropriately maintaining the drive status of each of the motors.
