[0023] The present invention provides a chassis electrical control method and system for a closed livestock and poultry vehicle and a whole vehicle controller, which are described below respectively.
[0024] like Figure 1 As shown, the present invention provides an electrical control method for a chassis dedicated to a closed livestock and poultry vehicle, comprising: S101, determining a comprehensive difference classification based on a difference between an output voltage of the generator and a terminal voltage of the battery, and a difference between an output current of the generator and a charging current of the battery; S102, when the vehicle is in operation with a load less than a preset load threshold, the comprehensive difference classification is in a preset high difference interval, and the remaining battery power is in a preset high power interval or medium power interval, controlling the generator to increase output voltage and output current; S103. When the vehicle is in operation with a load greater than a preset load threshold, the comprehensive difference classification is in a preset high difference range, and the remaining battery power is in a preset low power range, the engine controller is controlled to increase the engine speed.
[0025] It is understandable that the electric control method for the chassis of a closed livestock vehicle provided by the present invention can be executed by a vehicle controller (VCU), and is specifically applied to the electric control system of the chassis of a closed livestock vehicle. The electric control system of the chassis of a closed livestock vehicle provided by the present invention includes: a vehicle controller, an instrument (IC), an engine controller (ECM), a generator (IGU), and a battery detection sensor (IBS). Generally, the battery, the generator, and the electrical equipment are connected in series to form a circuit, and the electrical equipment may include a ventilation system.
[0026] The generator calculates the rated power consumption according to the electrical equipment of the vehicle, matches the power generation to be greater than the power consumption and is equipped with a CAN (Controller Area Network) module.
[0027] The battery is matched to meet the power supply type of the entire vehicle and is equipped with a battery remaining calculation system.
[0028] With the vehicle controller as the hub, the vehicle controller can connect to two CAN channels (power P / information I), connect the engine controller and generator to the CAN bus (PCAN) of the power channel, and connect the instrument and battery detection sensor to the CAN bus (ICAN) of the information channel.
[0029] The CAN bus of the power channel is mainly used for vehicle driving status detection, generator status detection, and intelligent power generation regulation (generator increases output voltage / engine increases speed).
[0030] The CAN bus of the information channel is mainly used for battery status detection and HMI (human-machine interface) display.
[0031] The output voltage and current detected by the generator are compared with the terminal voltage and charging current detected by the battery detection sensor, and a voltage / current comprehensive difference is taken. Based on the comprehensive difference, the comprehensive difference classification is determined. The comprehensive difference classification includes: low interval A (i.e.: low difference interval), middle interval B (i.e.: middle difference interval), and high interval C (i.e.: high difference interval).
[0032] The battery detection sensor can also detect the remaining power of the battery and determine the remaining power level corresponding to the remaining power of the battery: high interval X (i.e., high power interval), medium interval Y (i.e., medium power interval), low interval Z (i.e., low power interval).
[0033] The instrument will comprehensively judge the battery charging capacity and the remaining battery power through the vehicle controller, and give the battery health status. The health status is graded as follows: battery healthy, battery good, battery average, and battery very poor.
[0034] In some embodiments, the closed livestock and poultry vehicle chassis electrical control method further includes: When the generator is controlled to increase the output voltage and output current, or the engine controller is controlled to increase the engine speed, a notification to shut down the high-power electrical appliances is sent to the instrument.
[0035] It is understandable that high-power electrical appliances may be appliances with relatively high power, such as air conditioners or plug-in microwave ovens.
[0036] In some embodiments, the closed livestock and poultry vehicle chassis electrical control method further includes: When the vehicle is running at no-load, the comprehensive difference classification is in a preset low difference range, and the remaining battery power is in a preset low power range, the generator is controlled to increase the output voltage and output current.
[0037] In some embodiments, the closed livestock and poultry vehicle chassis electrical control method further includes: When the vehicle is running at no-load, the comprehensive difference classification is in the preset low difference range, and the remaining battery power is in the preset high power range or medium power range, a notification of the healthy battery status is sent to the instrument.
[0038] In some embodiments, the closed livestock and poultry vehicle chassis electrical control method further includes: When the vehicle operating condition is idling to load and unload the target object, the comprehensive difference classification is in the preset difference middle range, and the remaining battery power is in the preset medium power range or low power range, the generator is controlled to increase the output voltage and output current.
[0039] In some embodiments, the closed livestock and poultry vehicle chassis electrical control method further includes: When the vehicle operating condition is idling to load and unload the target object, the comprehensive difference classification is in the preset difference range, and the remaining battery power is in the preset high power range, a notification of the healthy battery status is sent to the instrument.
[0040] In some embodiments, the closed livestock and poultry vehicle chassis electrical control method further includes: When the vehicle is operating in an idling condition and the idling time exceeds the first target time, and it is currently raining weather, the comprehensive difference classification is in a preset high difference range, and the remaining battery power is in a preset low power range, the generator is controlled to increase the output voltage and output current, and the engine controller is controlled to increase the engine speed.
[0041] In some embodiments, the closed livestock and poultry vehicle chassis electrical control method further includes: After the duration of controlling the generator to increase the output voltage and output current and controlling the engine controller to increase the engine speed reaches a second target duration and the battery state is the original state, a notification of replacing the battery is sent to the meter.
[0042] In some embodiments, the control methods corresponding to different operating conditions of the vehicle refer to Table 1: Table 1: Combinations of different comprehensive difference levels and different remaining power levels
[0043] The different operating conditions of the vehicle include: Operating condition 1: When running without load, the ventilation and other upper electrical equipment are turned off, and the vehicle power load is small. The vehicle controller determines that the difference between the generator and the battery detection sensor broadcast on the bus is in the low range A. At this time, the vehicle controller believes that the battery charging capacity is good. If the remaining battery power is in the high range X or the middle range Y at this time, the vehicle controller does not take any action, determines that the battery status is healthy, and sends it to the instrument through the bus. The instrument displays the HMI on the interactive interface: the battery status is healthy. If the remaining battery power is in the low range Z at this time, the vehicle controller determines that the battery needs to be charged faster, and the bus command is given to the generator to increase the generator output voltage / current. At this time, the instrument displays: the battery status is good.
[0044] Operating condition 2: When loading or unloading the target object at idle speed, in order to ensure the air volume inside the car, the ventilation and other upper electrical equipment are turned on, and the vehicle power load is small. The vehicle controller judges that the difference between the generator and the battery detection sensor in the bus broadcast is in the middle interval B. At this time, the vehicle controller believes that the battery charging capacity is general. If the remaining battery power is in the high interval X at this time, the vehicle controller does not take any action and sends the status to the instrument through the bus. The HMI displays: The battery status is healthy. If the remaining battery power is in the middle interval Y or the low interval Z at this time, the vehicle controller determines that the battery needs to be charged faster, and the bus command is given to the generator to increase the generator output voltage / current. At this time, the instrument displays: The battery status is good.
[0045] Operating condition 3: When the load is on, the ventilation system needs to be turned on. If it is operating normally at this time, the vehicle has less other loads, and the difference between the generator and the battery detection sensor is in the low range A / B, it is regarded as the diagnostic logic of condition 1 / 2. If the vehicle has more other loads at this time, and the difference between the generator and the battery detection sensor is in the high range C, the vehicle controller determines that the battery's charging capacity is poor at this time. If the remaining battery power is in the high range X or the middle range Y at this time, the vehicle controller will be the same as in conditions 1 and 2. The bus command will increase the generator output voltage / current. At this time, the instrument HMI displays: battery status is normal. If the remaining battery power is in the low range Z at this time, the vehicle controller will determine that the current generator's power generation capacity is insufficient to meet the power demand. The vehicle controller actively requests the engine controller to increase the speed to improve the power generation capacity of the ICU. At this time, the HMI displays: battery status is normal. When the display status is normal, the text "Please turn off high-power appliances and charge!" is added at the same time, and the pop-up window is 5S, and the text reminder continues.
[0046] Operating condition 4: When the load idling time is too long and there is bad weather such as rainy days in summer, the ventilation system required by the upper body is turned on and the power load of the whole vehicle is too high. The detection difference between the generator and the battery detection sensor is in the high range C, and the remaining battery power is in the low range Z at this time. In addition to requesting the generator to increase the generator output voltage / current and requesting the engine controller to increase the engine speed, the vehicle controller will start to make internal time judgments. When this state lasts for 2 hours (the threshold can be calibrated) without improvement, the vehicle controller will determine that the battery is in very poor condition at this time. The HMI display: The battery condition is very poor, and a text reminder "Please replace the battery!" is added. The sound alarm lasts for 30S, and the text display has the highest priority.
[0047] Compared with the prior art solutions, the present invention has the following differences: 1. Increase the current capacity of the chassis generator for livestock and poultry vehicles and use power supply AGM batteries: (1) Design an intelligent high-current generator with a CAN module based on the power consumption of the ventilation system and other components of the vehicle.
[0048] (2) An AGM battery that matches the power supply type according to the idling condition and is equipped with a battery remaining capacity calculation system.
[0049] (3) The chassis design fully meets the market demand for livestock and poultry vehicles, and modification factories do not need to make additional modifications, thus avoiding the fire hazard caused by secondary modifications.
[0050] 2. Intelligent power management system realizes: battery status detection (battery terminal voltage / charging current, battery remaining power, battery health status), vehicle driving status detection, generator status detection (output voltage / current), intelligent power generation regulation, HMI display. According to the battery detection results, the generator charges the battery in time to avoid serious accidents such as suffocation and death of birds due to lack of oxygen caused by battery power supply.
[0051] The present invention has the following beneficial effects: 1. Under different working conditions, the integrated upper electrical equipment is matched with different electrical control systems to ensure the power consumption of the whole vehicle, extend the battery life, and avoid fire problems caused by non-standard modifications.
[0052] 2. The present invention can provide fault diagnosis reminders: (1) Battery status diagnosis, including: battery status healthy, battery status good, battery status fair, battery status very poor.
[0053] (2) Instrument text reminders and sound alarms, including: when the battery status is healthy or good, only the battery status is displayed in green, and no other text reminders are given; when the battery status is normal, a text reminder "Please turn off high-power appliances and charge!" is added to the display, the color is yellow, and a pop-up window appears for 5 seconds, and the text reminder continues.
[0054] (3) Added battery health status alarm, including: when the battery status is poor, the instrument will display the battery status as poor, and add a text reminder "Please replace the battery!". The text display has the highest priority and the color is red. A sound alarm is added and lasts for 30 seconds.
