Abstract

The invention provides a fuel oil driving and electric driving switching method for a manual transmission hybrid electric vehicle. In the manual transmission hybrid electric vehicle, a gear engagement hand shank and the bottom of a gear engagement device constitute one shift switch, and a dynamic clutch pedal and a fixed part constitute the other shift switch. The two switches cooperate for operation to conduct switching between an on state and a closed state of a fuel oil control circuit and a motor control circuit, so that switching of a fuel oil driving mode and an electric driving mode of the vehicle is realized. When the electric driving mode is switched to the fuel oil driving mode, in order to make an engine step in a transmission smoothly, a locking device is additionally arranged at a linkage point where the clutch pedal returns. When the rotational speed of the engine reaches a normal gear shifting rotational speed, the locking device loosens, and the clutch pedal returns in place.

First lighting a fire when hybrid vehicle starts and connect the total control circuit of vehicle, manual transmission handle of putting into gear now is hung At neutral, clutch pedal is not stepped on, and according to the narration of leading portion, connects in igniting the moment of the total control circuit of vehicle, combustion Oil control circuit is conducting, and circuit for controlling motor is turned off, present invention delay time set in advance point, such as 10 seconds or 20 Second, when manual transmission put into gear handle hang at neutral continue residence time exceed delay time set in advance point, simultaneously Also do not step on clutch, then circuit for controlling motor turn on automatically, fuel oil control circuit disconnect automatically, and accelerator pedal now controls electricity The output of motivation, because now shift handle hangs at neutral, fuel engines separates with drive system, so combustion Oil turbine will not produce impact to the operation of motor.

When the output of motor arrives maximum, vehicle cannot further accelerate, and driver can be according to speed now putting into gear Handle is hung to suitable gear, and in the moment that clutch pedal is stepped on, according to the narration of leading portion, circuit for controlling motor disconnects, with Time fuel oil control circuit connect, accelerator pedal now controls the rotating speed of fuel engines, in the process that shift handle is arbitrarily shifted gears In as 2 gears change 3 gears, 5 gears change 3 gears, shift handle need to be by neutral at, because now clutch pedal is stepped on, so fuel oil Electromotor the most normally works.As long as clutch pedal be step on or shift handle not at neutral, fuel engines all Straight normal work.When driver wants to use electric drive mode, only shift handle need to be hung the gear that makes the return trip empty, clutch pedal return, Then circuit for controlling motor turn on automatically, fuel oil control circuit disconnect automatically.For starting when the effect of delay circuit is automobile starting Machine provides the hot car time.

When electric drive mode is transformed into fuel oil drive pattern, for the intervention variator making electromotor smooth out, this programme A locking device is increased when clutch pedal is returned to linkage point, when engine speed reaches to shift gears normally rotating speed, Locking device unclamps, and clutch pedal is just returned to the end.

The invention has the beneficial effects as follows, it is achieved hybrid vehicle fuel oil drive pattern and electric drive mode are the most noiseless Normal work, realize manual gear hybrid vehicle fuel oil simultaneously and drive and motor-driven conversion.
