Control device for human-powered vehicle

A control device for a human-powered vehicle including a transmission device, a motor, a first detector including an acceleration sensor, and a second detector including a gyro sensor, the transmission device being configured to shift a transmission ratio that is a ratio of a wheel rotational speed of a drive wheel of the human-powered vehicle to a crank rotational speed of a crank axle of the human-powered vehicle, and the motor being configured to apply a propulsion force to the human-powered vehicle, the control device comprising:

• an electronic controller configured to control at least one of the transmission device and the motor;
• the electronic controller being configured to calculate an inclination angle of the human-powered vehicle from an output of the first detector and an output of the second detector;
• and
• the electronic controller being configured to perform at least one of a restriction of a first shifting action that increases the transmission ratio, a reduction of an assist ratio that is a ratio of an output of the motor to a human driving force applied to the crank axle, a reduction of an upper limit value of the output of the motor, and a reduction of the output of the motor in a case where an inclination change amount that is a change amount of the inclination angle is greater than or equal to a third change amount.
