Embodiment 1
[0029] Refer to attached figure 1 - attached figure 2 , a kind of accelerator pedal torque demand control method of dump truck of the present embodiment, comprises the following steps:
[0030] S100. Identify whether the vehicle has a power take-off configuration, and execute step S200 if there is a power take-off configuration, otherwise execute step S300;
[0031] S200. Detect whether the vehicle status meets the working requirements of the power take-off. The detection method is mainly by reading the signals inside the ECU, which signals are specifically referred to, and what state is considered to meet the requirements, "that is, the handbrake is pulled and the shift lever is in neutral and The transmission gear is in neutral, or the handbrake is released and the shift lever is in D gear and the transmission gear is in gear 1, and the power take-off status of the TCU is in the working state". requirements, when not satisfied, execute step S300;
[0032] S300. Detect wh...

An accelerator pedal torque demand control method of a dump truck comprises the following steps of S100, identifying whether a vehicle is provided with power takeoff configuration or not, when the vehicle is provided with the power takeoff configuration, executing a step S200, and otherwise executing a step S300; S200, detecting whether a vehicle state meets a working requirement of a power takeoff or not, if so, outputting a torque requirement of the motor end after the power takeoff MAP is inquired, and if not, executing the step S300; S300, detecting whether the vehicle state meets a forward gear driving requirement or not, if so, outputting a wheel end torque requirement after a D-gear MAP is inquired, and if not, executing a step S400; S400, detecting whether the vehicle state meets areverse gear driving requirement or not, if so, outputting a wheel end torque requirement after a R-gear MAP is inquired, and if not, executing a step S500; and S500, outputting a 0 torque demand. Two different control methods are used for meeting a pedal torque requirement when the power takeoff works and meeting the pedal torque requirement during normal running, and driving comfort is improved.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a method for controlling the acceleration pedal torque demand of a dump truck. Background technique [0002] At present, the accelerator pedal torque demand control method of general dump trucks is that the vehicle controller, that is, the VCU, calculates the pedal torque demand to the motor controller according to the motor speed and accelerator opening under the two conditions of power take-off operation and normal driving. , although this control method is simple in structure, its disadvantages are also obvious: low gear response is fast, high gear response is slow, and it cannot compensate for acceleration changes before and after shifting. Contents of the invention [0003] 1. The technical problem to be solved by the invention [0004] The purpose of the present invention is to solve the problem that the existing dump truck accelerator pedal torque ...
