Abstract: During turning of a vehicle, a vehicle body deceleration due to a cornering drag is obtained. An electronically controlled coupling is controlled to give, to rear wheels, a pre-torque set to be larger as the vehicle body deceleration is larger. Also, the pre-torque is restricted by an upper limit of the pre-torque that is set to be lower as a differential rotational speed of the front and rear wheels is smaller. By giving the pre-torque to the rear wheels, if a shift condition for a four-wheel drive state is established subsequently, a driving force can be generated in the rear wheels substantially at the same time that a fastening force of the electronically controlled coupling is increased, thereby the shift to the four-wheel drive state is immediately completed. Consequently, delay in response is not generated in the shift.

The first light module emits light that indicates the angle of the tow bar respective to the surface of the vehicle and the second light module emits light that indicates the direction of the wheels of the vehicle.

Abstract: A propulsion system for human powered vehicles includes an outer lever having an input end and an output end. An orbiting sprocket is coupled to the output end of the outer lever. A fixed sprocket is also provided, with the orbiting sprocket orbiting around the fixed sprocket. A closed tension-bearing member engages an outer circumference of both the orbiting sprocket and the fixed sprocket. A driveshaft is co-axial with the fixed sprocket, the driveshaft being free to rotate with respect to the fixed sprocket and the crank lever being fixedly connected to the driveshaft and rotationally connected to the orbiting sprocket. A chassis is propelled by the driveshaft. Wherein application of a force on the input end of the outer lever causes the orbiting sprocket to orbit around the fixed sprocket and thereby rotate the crank lever to impart rotation to the driveshaft and propel the chassis.
