A vehicle, torque output method and device

Abstract

The invention relates to a vehicle, a torque output method and a device. The method includes the following steps: detecting the actual mass of the vehicle, the current speed and the current opening of the accelerator pedal; The output torque calibration value of the engine / drive motor when the vehicle is unloaded at the same speed, the output torque calibration value of the engine / drive motor when the vehicle is fully loaded at the current speed and the current accelerator pedal opening, and the current vehicle speed and the current accelerator pedal opening are obtained. Next, the output torque value of the engine / drive motor corresponding to the actual mass of the vehicle; and then used to control the engine / drive motor. The method adjusts the power output of the vehicle at different vehicle speeds and different accelerator pedal openings according to the actual mass of the vehicle to ensure that the dynamic performance of the vehicle remains consistent during driving and satisfies the power adaptive adjustment within the range of the actual mass of the vehicle.

Description

technical field [0001] The invention relates to a vehicle, a torque output method and a device, and belongs to the field of vehicle power assembly control. Background technique [0002] Commercial vehicles, such as city buses, logistics vehicles, etc., during operation, the quality of the vehicle often changes in a wide range due to loading and unloading passengers or loading and unloading goods. At this time, the driver needs to constantly adjust the driving style to take into account the vehicle's Comfort, economy and driving safety. [0003] At present, commercial vehicles generally have a variety of driving modes for the driver to choose from. Each driving mode corresponds to an engine or drive motor output power setting, and the driver can manually adjust it according to actual needs. For example, some medium- and heavy-duty trucks are equipped with multi-state switch buttons to set three maximum power output modes for no-load, half-load and full-load, which can be man...

Problems solved by technology

[0005] The purpose of the present invention is to provide a vehicle torque output method to solve the problem in the prior art that different actual vehicle masses may correspond to one engine power output, which cannot satisfy the power adaptive adjustment within the range of actual vehicle mass variation. At the same time, a vehicle torque output device is also provided to solve the problem that the existing technology cannot satisfy the power self-efficacy within the range of the actual mass change of the entire vehicle due to the fact that different actual vehicle masses may correspond to one engine power output. The problem of adapting to the needs of adjustment; at the same time, a vehicle is also provided to solve the problem that the existing technology cannot satisfy the power self-adaptation within the range of actual mass variation of the entire vehicle due to the fact that different actual vehicle masses may correspond to one engine power output The question of the need for regulation
