Embodiment Construction

[0025] Embodiment of uniform speed control method for pure electric sanitation vehicle

[0026] The uniform speed control method provided by the present invention is suitable for pure electric sanitation vehicles. Sanitation vehicles refer to special vehicles used for urban city tidying and cleaning. The sanitation vehicles in this embodiment are: sprinkler vehicles, sweeping vehicles, cleaning vehicles, and haze removal vehicles. Cars and other work vehicles that need to run at a constant speed during work. And in order to implement the constant speed control method in this embodiment, a control system of a pure electric sanitation vehicle is also provided in this embodiment, and each component of the system is a hardware device.

[0027] Such as figure 1 As shown, the control system includes a gear detection module, a vehicle speed detection module, an accelerator pedal opening detection module and a brake pedal opening detection module, wherein the gear detection module is...

Abstract

The invention relates to a pure-electric environmental sanitation vehicle constant-speed control method and device. The method includes the steps that firstly, gear information, vehicle speed information, accelerator pedal opening degree information, brake pedal opening degree information and vehicle fault information of a vehicle are detected; and then, when the vehicle speed is in the operationworking speed interval of the vehicle, the accelerator pedal opening degree is not changed within set time, a gear signal of the vehicle indicates a forward gear and the gear is not shifted within theset time, no effective brake pedal opening degree signal is sent out within the set time, and when the vehicle has no fault forbidding constant-speed control, the vehicle is controlled to travel at the current constant speed. Through control of the constant-speed control method, the pure-electric environmental sanitation vehicle can be in a constant-speed traveling state and also a low-stable-speed driving state, a driver does not operate an accelerator pedal for a long time and does not accurately control the accelerator pedal, and the driver control burden and labor operation intensity arereduced.

Description

technical field [0001] The invention relates to a method and a control device for controlling a uniform speed of a pure electric sanitation vehicle, and belongs to the technical field of uniform speed control of a pure electric sanitation vehicle. Background technique [0002] In 2014, the State Council issued the "Guiding Opinions of the General Office of the State Council on Accelerating the Promotion and Application of New Energy Vehicles", which stated that pure electric drive should be the main strategic orientation for the development of new energy vehicles, and vehicles used in public services should be promoted as new energy vehicles. application breakthrough. The sanitation system is a part of the public service field, and the government of each new energy vehicle demonstration and promotion city will also purchase and use pure electric sanitation vehicles as part of the work plan for the promotion and application of new energy vehicles. New energy sanitation vehic...
