Abstract: This control system comprises: a control device which, while a vehicle is driven, receives power to control the operation of a moving part and which, while the vehicle is stopped, does not receive power; and a system which is capable of communicating with the control device, and which, when the vehicle is stopped, receives power so as to be capable of ascertaining first information pertaining to time or which is capable of acquiring, during the driving, second information pertaining to times before and after when the vehicle was stopped. When the vehicle is restarted after being stopped, the control device uses at least one of the first information and the second information received from the system to ascertain the time elapsed while the vehicle was stopped, and uses the elapsed time to control the operation of the moving part.

Abstract: This motor shaft state detection method has: a rotation determination step for determining, using a detected current waveform of a motor, whether or not to be a non-rotational state in which the rotational speed of the motor is smaller than a predetermined speed; a current determination step for determining whether or not to be a supply state in which the absolute value of current supplied to the motor is larger than a predetermined reference value; and a determination step for, when it is determined to be the non-rotational state in the rotation determination step and it is determined to be the supply state in the current determination step, determining that the motor is in a shaft locked state.

Abstract: A processing device is configured to perform a process of bringing a response speed of a first sensor close to a response speed of a second sensor when a value using a detection value of the first sensor is extracted at a timing determined by using an output value of the second sensor having a response speed different from that of the first sensor.

Abstract: A control device controls a damping force of a damping device, which damps a force generated between a vehicle body of a two-wheeled vehicle and at least one of a front wheel and a rear wheel, by using an angular velocity of rotational movement in a front-rear direction of an unsprung part of the two-wheeled vehicle, which is generated due to a difference between a velocity in an up-down direction of the front wheel and a velocity in the up-down direction of the rear wheel.
