Description
Technical Field
The invention relates to the technical field of power generation control of range extenders, in particular to a range extender system and a method for removing an acceleration signal wire.
Background
The range extender is a sustainable power generation device which converts chemical energy into kinetic energy and then converts the kinetic energy into electric energy by burning fuel oil. At present, the range extender is matched with a storage battery for use, is applied to various hybrid electric vehicle fields, generates electricity through the range extender, and greatly increases the endurance mileage of the pure electric vehicle. Under the condition that the range extender is installed on the pure electric vehicle, the purpose of infinite endurance can be realized as long as fuel is filled into the range extender.
The working logic of the hybrid vehicle provided with the range extender at present is that the range extender is started by a storage battery or a hand-pulling disc to enter an idle mode; when the range extender controller detects an acceleration signal on the vehicle, the range extender enters a power generation mode to provide energy for the running of the vehicle and charge a storage battery; and when the range extender controller detects that the vehicle-mounted acceleration signal is withdrawn, the range extender enters an idle mode. The range extender generates power circularly through the working logic and continuously provides energy.
The existing range extender needs to enter or exit a power generation mode through an acceleration signal on a vehicle. The acceleration signal on the vehicle comprises a handle rotating signal, an accelerator pedal signal, a three-phase signal of a vehicle-mounted motor, a Hall current signal and the like. The external interference of the acceleration signal comprises electromagnetic interference, induced electromotive force interference and the like. On one hand, the on-board acceleration signal needs to provide a signal for an on-board controller to drive the vehicle to normally accelerate; on one hand, a signal is also provided for the range extender controller to control the range extender to enter the power generation mode. Firstly, as long as an acceleration signal of one system is abnormal, the two systems interfere the normal operation of the other system; secondly, an additional acceleration signal line is needed to install the range extender, and the signal line is easily interfered by other external factors. For example, the vehicle is interfered not to be accelerated or stopped; the interference to the range extender does not generate power and does not return to the idle speed, thereby causing the phenomena of 'no driving', 'galloping' and the like.

3) after the range extender controller receives a starting switch opening signal, the range extender is started through a storage battery or a hand-pulling disc, the range extender enters a hybrid mode after the starting is successful, at the moment, the range extender controller controls the range extender to stably generate power at the rotating speed S1 of the hybrid mode, at the moment, the voltage information U1 of the storage battery is collected through AD, in the hybrid mode, the vehicle keeps a static state and does not consume energy, the power generated by the range extender is all used for charging the battery, the charging current is less than or equal to 5A, and at the moment, the range extender and the storage battery reach the balance of the hybrid mode;
4) after the pedal is stepped on, the vehicle needs energy to drive the vehicle to run, the hybrid mode balance is broken, the storage battery voltage information U1 collected by the AD is reduced, when the range extender controller detects that the voltage information U1 of the storage battery is reduced by 1V, the range extender enters a hybrid power generation mode, the range extender controller controls the range extender to generate power stably at the rotating speed S2 of the hybrid power generation mode, the voltage information U2 of the storage battery is collected through AD, the vehicle keeps a running state and consumes energy under the hybrid power generation mode, the storage battery provides energy at first, then the power generated by the range extender and the storage battery provide energy for the vehicle together, after the stability, the running energy of the vehicle is provided by the power generated by the range extender, the redundant power generation energy of the range extender charges the storage battery, the charging current is less than or equal to 10A, and the range extender, the storage battery and the vehicle reach the balance of a hybrid power generation mode at the moment;
5) after the pedal is released, the energy required by the vehicle is reduced and the brake of the vehicle generates extra energy, so that the hybrid power generation mode balance is broken, the voltage information U2 of the storage battery acquired by the AD is increased, and the rotating speed S2 of the range extender in the hybrid power generation mode is increased; when the range extender controller detects that the voltage information U1 of the storage battery is increased by 2V and the rotating speed S2 of the hybrid power generation mode is increased by 200RPM, the range extender exits the hybrid power generation mode and enters the hybrid mode; the range extender circularly generates power according to the working logic and continuously provides energy for the battery and the vehicle under different states;

The range extender generates power circularly through the working logic and continuously provides energy.
The range extender system removes the working logic of an acceleration signal line: the range extender is started through a storage battery or a hand-pulling disc, and enters a hybrid mode after the range extender is started successfully; when the range extender controller detects that a load intervenes to break the hybrid mode, the range extender enters the hybrid power generation mode; and after the load exits, the range extender enters the hybrid power generation mode after the range extender controller detects that the hybrid power generation mode is broken. The range extender circularly generates power according to the working logic and continuously provides energy.
Compared with the prior art, the invention has the following beneficial effects:

the problem that external factors interfere with the acceleration signal wire is effectively avoided;
the phenomena of 'no driving', 'flying' and the like of the vehicle are avoided;
