Engine control system for a combination car system

摘要

A combination car system is 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, and an engine the output of which is controlled by a first engine output control element. The second car includes a pair of front wheels, a pair of rear wheels by which it is driven, and an engine the output of which is controlled by a second engine output control element. When the cars are running independently, displacement of an accelerator pedal in the first car is transmitted by a first displacement transmission mechanism to the first engine output control element, and displacement of an accelerator pedal in the second car is transmitted by a second displacement transmission mechanism to the second engine output control element. The second displacement transmission mechanism includes: a connection unit; a first displacement transmission submechanism which is detachably coupled to, and which transmits displacement of the accelerator pedal of the second car to, this connection unit; and a second displacement transmission submechanism, which transmits displacement of this connection unit to the second engine output control element. The first car and the second car are couplable together into a combination car which runs on the front wheels of the first car and on the rear wheels of the second car, the rear wheels of the first car and the front wheels of the second car being at this time removed from road contact. At this time, the coupling of the first displacement transmission submechanism is removed from the connection unit, and a third displacement transmission mechanism is fitted to extend between and to transmit displacement between a part of the first displacement transmission mechanism in the first car and the connection unit. Thereby both the engines of the combination car may be controlled by using the accelerator pedal of the first car, and the accelerator pedal of the second car is at this time disenabled.
