Abstract

Abstract A combination car system made up from a first car and a second car, both of which are capable of running independently. The first car includes a pair of front wheels by which it is driven, a pair of rear wheels, an engine, a braking system, and a transmission; and the engine, the braking system, and the transmission, when the first car is running independently, are controlled from the first car. The second car includes a pair of front wheels, a pair of rear wheels by which it is driven, an engine, a braking system, and a transmission. The engine, the braking system, and the transmission, when the second car is running independently, are controlled from the second car. The first car and the second car are couplable together into a coupled car which runs on the pair of front wheels of the first car and the pair of rear wheels of the second car, with the pair of rear wheels of the first car and the pair of front wheels of the second car being removed from road contact. The operation of the engine of the first car is at this time coupled to the operation of the engine of the second car, so that the combined operation of both these engines is controlled from the first car; and the operation of the braking system of the first car is coupled to the operation of the braking system of the second car, so that the combined operation of both these braking systems is controlled from the first car. Further, at this time the transmission of the second car is controlled from the first car.
