Abstract
A hybrid-power driving system (HPDS) (110) includes an engine, a motor, and a transmission. The HPDS may include a single clutch and the transmission can provide at least six forward speed ratios and can provide for a reverse speed ratio. The transmission can include three synchronizers and multiple gearwheels that are used in multiple speed ratios. In addition to a pure engine driving mode and a pure motor driving mode, the HPDS can operate using a hybrid-power driving mode (HDM). In the HDM, the HPDS can provide for shifting of gears without power interruption to the half-axles and wheels of a vehicle. In the HDM, the continuous power being output can be achieved by keeping a synchronizer engaged to a gearwheel for two consecutive speed ratios.
