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.

    本发明的一种自卸车的加速踏板扭矩需求控制方法,包括如下步骤:S100、识别车辆有无取力器配置,当有取力器配置时执行步骤S200,反之执行步骤S300;S200、检测车辆状态是否满足取力器工作要求,当满足时,查询取力MAP后输出电机端扭矩需求,当不满足时执行步骤S300;S300、检测车辆状态是否满足前进挡行车要求,当满足时,查询D挡MAP后输出车轮端扭矩需求,当不满足时执行步骤S400;S400、检测车辆状态是否满足倒车挡行车要求,当满足时,查询R挡MAP后输出车轮端扭矩需求,当不满足时执行步骤S500;S500、输出0扭矩需求。对取力器工作时的踏板扭矩需求和正常行车时的踏板扭矩需求使用两种不同的控制方法,改善了驾驶舒适性。
