Embodiment 1

[0088] In order to solve the problem that the result of the vehicle demand torque calculated by the calculation method of the accelerator pedal demand torque in the prior art cannot reflect the driver's torque demand, such as Figure 1-Figure 2 As shown, the implementation of this embodiment discloses a calculation method for the required torque of the vehicle, including the following steps:

[0089] S1-1 first obtains the accelerator pedal position signal and the vehicle speed signal, the accelerator pedal position signal is obtained through the accelerator pedal position sensor, and the vehicle speed signal can be obtained through the car dashboard. Specifically, the model of the accelerator pedal position sensor may be: 18919-VK50, or other models, which are selected according to actual needs, and are not specifically limited in this embodiment. Secondly, after performing zero-crossing virtualization calculation processing on the obtained accelerator pedal position signal a...

Embodiment 2

[0127] Such as image 3 As shown, this embodiment also provides a calculation system for the required torque of the whole vehicle, including an accelerator pedal position sensor 100, a vehicle speed signal sensor 200, a zero-crossing virtualization module 300, a calculation module 400 and a torque MAP diagram module 500 connected in communication ;in,

[0128] The accelerator pedal position sensor 100 acquires the accelerator pedal position signal and sends it to the zero-crossing virtualization module 300, wherein the model of the accelerator pedal position sensor 100 can be: 18002VM00B, and can also be other models, which are specifically selected according to actual needs. This is not specifically limited.

[0129] The vehicle speed signal sensor 200 obtains the vehicle speed signal and sends it to the zero-crossing virtualization module 300; wherein, the model of the vehicle speed signal sensor 200 can be: 3802060E61B, and can also be other models, which are selected acco...

Abstract

The invention discloses a calculation method and system for the required torque of a complete vehicle, wherein the calculation method includes the following steps: after performing zero-crossing virtualization calculation processing on the accelerator pedal position signal and the vehicle speed signal, outputting a zero-crossing virtualization accelerator pedal relative position signal ; Based on the vehicle speed signal and the zero-crossing virtualized accelerator pedal position signal, the torque MAP diagram is generated to obtain the static torque demand signal; the dynamic torque demand signal is generated according to the accelerator pedal position signal through derivation processing; the static torque demand signal and the dynamic torque demand signal are superimposed to obtain The vehicle needs torque. The calculation method of the vehicle demand torque provided by the present invention introduces zero-crossing virtualization calculation processing. The accelerator pedal is not only interpreted as the driver's desire (expressed through the static torque demand signal), but also further analyzes the intensity of the driver's desire (the intensity of the dynamic torque demand signal), so that the driving force can be completely analyzed. torque requirements of the crew.

Description

technical field [0001] The invention relates to the field of accelerator pedal torque control, in particular to a method and system for calculating the required torque of a complete vehicle. Background technique [0002] Usually, the required torque of the accelerator pedal is calculated by searching the MAP diagram (input: accelerator pedal position signal and vehicle speed signal; output: required torque of the vehicle) to calculate the required torque of the vehicle. [0003] Since the existing calculation factor of the accelerator pedal demand torque only involves the accelerator pedal position signal and the vehicle speed signal, it does not take into account the driver's demand willingness, let alone analyze the intensity of the driver's demand willingness. [0004] Therefore, the result of the vehicle demand torque calculated by the calculation method of the accelerator pedal demand torque adopted in the prior art cannot reflect the driving intention of the driver. ...
