Abstract
A new technical scheme of vehicle with electronic control and hydrostatic drive (ECHD) is proposed in the paper. To make out the drive/brake features of the vehicle, a model, combined with the vehicle dynamics and hydrostatic transmission dynamics, and the corresponding simulation program is developed, in which, a gas-charged accumulator is used as power source and energy storage component. In this paper, three main misuses are investigated, i.e. the energy recover and consumption of hydrostatic transmission when drive/brake, vehicle dynamics parameters in drive/brake and how the key components, hydraulic variable motor and accumulator, contributing to the performance. The result of simulation shows some characteristic features of the ECHD vehicle, which should be paid attention on when study the ECHD vehicle.
