Abstract: There is provided an electrically driven vehicle that well balances calculation volumes and communication volumes of two control devices configured to drive and control motors for driving. The electrically driven vehicle comprises at least one motor for driving and a first control device and a second control device configured to control the motor. The first control device is configured to calculate a target torque that is to be output from the motor, based on information including an accelerator position, to calculate a current command based on the calculated target torque, and to send the calculated current command to the second control device. The second control device is configured to use the current command, a phase current of the motor and a rotational angle of the motor such as to drive the motor by feedback control.

Abstract: A sensor holding member holding a position sensor and an attachment member that attaches the sensor holding member to a cylinder tube are formed separately. The sensor holding member is placed with a sensor attachment groove oriented in the direction of the axis of the cylinder tube and in contact with the outer surface of the cylinder tube. The attachment member is placed so as to straddle the sensor holding member. By tightening an attachment screw and fixing the attachment member with an attachment band, the sensor holding member is pressed against and fixed to the outer surface of the cylinder tube by the attachment member. Loosening the attachment screw allows the sensor holding member to be displaced relative to the attachment member in the direction of the axis of the cylinder tube.
