Abstract

The embodiment of the invention discloses a determining method and device of the driving required torque, a vehicle and a storage medium. The determining method comprises the steps: a pre-stored information association list is searched, a first associated information item and a second associated information item corresponding to a target driving mode of the current vehicle are determined, according to the first associated information item, the output torque corresponding to the current vehicle speed of the target driving mode is determined, according to the second associated information item,the weight coefficient corresponding to the current accelerator pedal opening degree of the target driving mode is determined, and according to the output torque and the weight coefficient, the current driving required torque of the target driving mode is determined. Compared with the prior art, based on the current vehicle speed and the current accelerator pedal opening degree, the correspondingoutput torque and weight coefficient are determined, then the driving required torque is determined according to the output torque and the weight coefficient, and the current driving required torque of the target driving mode is effectively determined.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicle control, and in particular to a method, device, vehicle and storage medium for determining driving demand torque. Background technique [0002] Pure electric vehicles have the advantages of zero emission and low energy consumption, and are more and more widely used in daily life. With the continuous improvement of user needs, the performance of the vehicle is also constantly developing, such as power and economy are getting better and better. [0003] The driving demand torque refers to the driver's torque demand for the vehicle power system, which has a great impact on the drivability, economy and power performance of the vehicle. In the current existing technologies, most of the single mapping relationship between vehicle speed or accelerator pedal opening and driving demand torque is used to determine the driving demand torque, and some focus on correcting or selectin...
