The present disclosure relates to an electronic parking brake system including a motor actuator operated by an electric motor, wherein the electronic parking brake system further includes a motor driving circuit provided to drive the electric motor, and a controller configured to determine a temperature of the electric motor from a temperature of a brake disc during a parking operation, determine a target current based on the determined motor temperature, and control the electric motor depending on the determined target current.

Apparatuses, systems, and methods apply, with a fan, a braking force to a vehicle that includes an axle. The fan is rotated at a first rotational speed based on a rotation of the axle that rotates at a second rotational speed. The first rotational speed is different from the second rotational speed. The fan applies the braking force when the fan rotates at the first rotational speed.

An in-wheel motor drive device (1) is arranged inside a wheel (W) of a wheel (92). The in-wheel motor drive device (1) includes a motor rotating shaft that rotates the wheel, as well as a motor unit (21) including a motor casing (29) that houses the motor rotating shaft, and a plurality of cooling fins (41) provided protruding from an inner end surface (29e) in a vehicle width direction of the motor casing and extending along a vehicle front-rear direction.
