A transmission device includes a mounting frame having an abutting member, a driving sleeve sleeved fixedly on a drive shaft extending through the base plate, a transmission wheel sleeved rotatably on the driving sleeve, and a connecting post extending through a radially extending through hole in the transmission wheel and into a spiral first guiding groove in the driving sleeve having opposite first and second ends. A position-limiting member is disposed rotatably on a side surface of the transmission wheel. A ball is disposed in a ball-receiving hole in the position-limiting member and is movable in a curved second guiding groove in the side surface of the transmission wheel having a shallower first end and a deeper second end. When the drive shaft rotates regularly and reversely, the ball is spaced apart from the abutting member.

A vehicle stability control method is to be performed by a vehicle stability control system of a motor vehicle, and includes the steps of: detecting an actual yaw rate, and obtaining a plurality of detection values by detecting a vehicle speed and a steering wheel angle, and at least one operation status selected from a lateral acceleration status, a load status and a steering wheel angular speed status; obtaining a plurality of intermediate weight values, from which a steering characteristic value is determined, based on the obtained detection values; obtaining a target yaw rate based on the vehicle speed, the steering wheel angle and the steering characteristic value; and controlling steering of road wheels according to difference between the target and actual yaw rates.

A driving device for a parking brake system includes a casing shift member, a brake cable and a driving member. The casing shift member includes a cable casing. The brake cable is mounted through the cable casing. The driving member has a driving unit connected to and driving the casing shift member to perform a longitudinal motion. Thus the cable casing applies a force on the brake cable so as to perform a brake work. Because the brake cable is tightened with the force provided by the cable casing, the brake cable is only bent slightly. Thus the curvature of the brake cable is small. That prevents the brake cable from being damaged and prolongs a life span of the brake cable. Moreover, a mechanical efficiency of the driving device is improved because the brake cable is tightened with the force provided by the cable casing.
