Embodiment 1
[0088] In order to solve the problem that the required torque of the whole vehicle calculated by the calculation method of the required torque of the accelerator pedal in the prior art cannot reflect the torque demand of the driver, such as Figure 1-Figure 2 As shown, the implementation of this embodiment discloses a method for calculating the required torque of a 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 specifically selected according to actual needs, and this embodiment does not specifically limit this. Secondly, after the obtained accelerator pedal position signal and the vehicle speed signal are subjected ...
Embodiment 2
[0127] Such as image 3 As shown, this embodiment also provides a system for calculating the required torque of the 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 module 500 that are communicatively connected to each other. ;among them,
[0128] The accelerator pedal position sensor 100 obtains the accelerator pedal position signal and sends it to the zero-crossing virtualization module 300. The accelerator pedal position sensor 100 can be modeled as: 18002VM00B or other models. It can be 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; the model of the vehicle speed signal sensor 200 can be: 3802060E61B, or other models, which can be selected according to actual needs, and this embodiment wi...
