Cleaning car with single engine and accelerator control system and method thereof

Abstract

The invention discloses a cleaning car with a single engine and an accelerator control system and a method thereof. The system comprises a first controller for enabling a chassis ECU (Engine Control Unit) when the cleaning car is in a running conveying state and for stopping enabling the chassis ECU and enabling the accelerator controller when the cleaning car is in an operating working state; a speed adjusting gear changing device for providing optional operation working condition gears for a user and for acquiring the operation working condition gear information chosen by the user; an engine rotary speed sensor for detecting the current real rotary speed signal of the engine; an accelerator controller for outputting a speed control signal to the chassis ECU according to the operation working condition gear information if the accelerator controller receives the enabling signal from the first controller; and a chassis ECU for controlling the rotary speed of the engine under the control of the enabling signal from the first controller or for adjusting the rotary speed of the engine according to the speed control signal if the chassis ECU receives the speed control signal from the accelerator controller.

Description

technical field [0001] The invention relates to the technical field of a single-engine sweeper, in particular to a single-engine sweeper and a throttle control system and method thereof. Background technique [0002] Now the single-engine sanitation vehicle has become a development trend, which uses the chassis engine to provide power for the vehicle's walking and cleaning components, which not only reduces the fuel consumption during operation, saves the cost of use, but also reduces exhaust emissions and reduces Operating noise effectively protects the environment. [0003] The single-engine sanitation vehicle is powered by one engine for all components. At present, the commonly used throttle control method in single-engine sanitation vehicles is the manual throttle (mechanical) control method. It is too large, and on a relatively clean road, the operator will pull the accelerator too much, wasting energy. This single-engine sanitation vehicle also cannot limit the forwa...

Problems solved by technology

[0004] Moreover, as the vehicle's operating conditions or operating road conditions change, the load on the engine also changes. For different operating conditions, the corresponding load may suddenly increase or decrease a lot

In this way, when the vehicle selects a specific operating mode, the engine speed may suddenly drop or accelerate, which will easily cause the quality of the car washing operation to decrease and the fuel consumption to increase.
