Abstract
The hybrid vehicle kit comprises a vehicle body capable of being interchangeably coupled to either one of a wheel kit thus forming a hybrid vehicle in a wheel mode, the wheel kit having a number of ground-engaging wheels; and a track kit, thus forming the hybrid vehicle in a track mode, the track kit having a pair of ground-engaging tracks carried by track wheels. The vehicle has a pair of powered driving hydraulic pumps and a number of wheel drives powered by a corresponding one of the driving hydraulic pumps. In the wheel mode the ground-engaging wheels are operatively mounted to corresponding wheel drives and an electronic circuit calculates hydraulic rate data on the basis of speed data to control the first and second driving hydraulic pumps so that they will administer a hydraulic rate to the wheel drives which is representative of the hydraulic rate data to control the rotational speed of the ground-engaging wheels which will propel the hybrid vehicle. In the track mode at least some of the track wheels are operatively mounted to corresponding wheel drives and the electronic circuit calculates hydraulic rate data on the basis of the speed data and of the steering data to cont…
