Embodiment 1

[0055] Such as Figure 1~2 As shown, a signal conversion method of an accelerator pedal of a hybrid vehicle includes an accelerator pedal 10, an ECU20 and a VCU30, wherein:

[0056] It turns out that the accelerator pedal has multiple contacts, and the two positive poles are combined to a common positive pole of 5V, the two negative poles are combined to be changed to a common negative pole of 0V, and the signal S1 and signal S2 remain unchanged; thus, the accelerator pedal has four signals contact;

[0057] It turns out that the ECU has multiple contacts, and the two positive poles are merged to a common positive pole of 5V, the two negative poles are combined to be changed to a common negative pole of 0V, and ECU-2 and ECU-3 remain unchanged; thus, the ECU has four signals contacts,

[0058] It turns out that the VCU has multiple contacts, and the two positive poles are merged into a common positive pole 5V, and the two negative poles are combined into a common negative po...

Embodiment 2

[0062] As an improvement of Embodiment 1 of the present invention, such as figure 1 Shown:

[0063] The line signal switching device adopts an acceleration relay J1 and an acceleration hybrid relay J2, and the VCU30 controls the acceleration relay J1 and the acceleration hybrid relay J2;

[0064] When only driving the motor, the signal contact of the accelerator pedal communicates with the signal contact of the VCU through the acceleration forward relay J1;

[0065] When only the engine is driving, the signal contact of the accelerator pedal communicates with the signal contact of the ECU through the acceleration forward relay J1;

[0066] When the driving motor and the engine are driven in a mixed manner, the accelerator pedal signal contact communicates with the signal contact of the VCU through the accelerator forward relay J1; and the accelerator hybrid relay J2 transmits the analog accelerator pedal opening signal to the signal contact of the ECU.

Embodiment 3

[0097] As an improvement of Embodiment 1 of the present invention, such as figure 2 Shown:

[0098] D1-D2 represent voltage isolation diodes, and D3-D5 represent light-emitting indicator diodes.

[0099] The line signal switching device is five optocoupler tubes, which are optocoupler tube one U1, optocoupler tube two U2, optocoupler tube three U3, optocoupler tube four U4, and optocoupler tube five U5;

[0100] Receive the electric switch signal, that is: when only the drive motor is driven, the signal contact of the accelerator pedal is connected to the signal contact of the VCU through the photocoupler three U3 and the photocoupler four U4;

[0101] Receive the oil switch signal, that is, when the engine is only driven, the signal contact of the accelerator pedal is connected to the signal contact of the ECU through the optocoupler tube 1 U1 and optocoupler tube 2 U2;

[0102] Receive the hybrid switch signal, that is: when the driving motor and the engine are mixed driv...

Abstract

The invention relates to a signal conversion method of an accelerator pedal of a hybrid electric vehicle. The signal conversion method is suitable for signal conversion control of the accelerator pedal of an oil-electric hybrid electric vehicle. According to the technical scheme, the signal conversion method for the accelerator pedal of the hybrid electric vehicle comprises the accelerator pedal (10), an ECU (20) and a VCU (30), and is characterized in that the accelerator pedal is provided with four signal contacts; the ECU is provided with four signal contacts, and the three signal contacts of the VCU control the switching of the line signal switching device; and signals of the accelerator pedal are switched between the VCU and the ECU through the line signal switching device. After the technical scheme is adopted, signals of the accelerator pedal are converted to the ECU / VCU without depending on a CAN bus interface of the ECU of an original vehicle engine, and direct combination of the pedal, the ECU and the VCU is achieved.

Description

technical field [0001] The present invention relates to a signal conversion method of an accelerator pedal of a hybrid electric vehicle, which is suitable for the signal conversion control of the accelerator pedal of a gasoline-electric hybrid vehicle. [0002] The second invention relates to a signal conversion system for an accelerator pedal of a hybrid electric vehicle, which is suitable for the signal conversion control of the accelerator pedal of a gasoline-electric hybrid vehicle. Background technique [0003] The national "Energy Conservation and New Energy Automobile Industry" once again clarified the development strategy of "pure electric drive" from the policy level, which has also become the core principle for the development of new energy vehicles. [0004] Pure electric vehicles, along with the development of industrial technology, allow more and more motors to participate in the driving process of the vehicle to meet the purpose of energy saving and emission re...
