Example two
Fig. 4 is a flowchart of a vehicle cold air control method according to a second embodiment of the present invention, where the present embodiment is applicable to a case of cooling an autonomous driving host, and the method may be executed by a vehicle cold air control device, and the device may be implemented by software and/or hardware.
As shown in fig. 4, the method specifically includes the following steps:
and step 110, acquiring the temperature of the automatic driving host, and determining whether the temperature of the air inlet of the automatic driving host is greater than a second temperature threshold when the temperature of the automatic driving host is greater than a first temperature threshold.
The temperature of the automatic driving host can be understood as the temperature value of the automatic driving host. The host air inlet temperature can be understood as the temperature value of the vent between the vehicle passenger compartment and the autopilot host. The first temperature threshold and the second temperature threshold can be calibrated in advance according to a specific vehicle type, and the second temperature threshold can be smaller than the first temperature threshold.
Specifically, when the vehicle travels, the vehicle cold air control device can acquire the temperature of the automatic driving host in real time, and when the temperature of the automatic driving host is greater than a first temperature threshold value, for example, the temperature of the automatic driving host is greater than 55 ℃, the temperature of the automatic driving host can be considered to be higher, and the temperature needs to be reduced, so that the temperature of an air inlet of the host can be judged, and whether the gas temperature of a passenger compartment meets the condition of reducing the temperature of the automatic driving host or not can be checked.
And step 120, if the temperature of the air inlet of the host is greater than a second temperature threshold, determining a refrigeration requirement according to the illumination intensity, the ambient temperature and the current vehicle speed, and controlling the air conditioning box to operate according to the refrigeration requirement.
The illumination intensity can be understood as the intensity value of illumination in the environment where the vehicle is located at the current time. The ambient temperature can be understood as a temperature value of the environment in which the vehicle is located at the present moment. The current vehicle speed can be understood as the driving speed value of the vehicle at the current moment. The refrigeration demand can be understood as the required refrigeration strength value of the vehicle at the current moment, and can be represented by the refrigeration power of the air conditioning box, and the larger the refrigeration demand is, the larger the running power of the air conditioning box is.
Specifically, if the temperature of the air inlet of the host is greater than the second temperature threshold, for example, the temperature of the air inlet of the host is greater than 40 ℃, it can be considered that the temperature of the air in the passenger compartment is also higher, and at this time, the temperature of the autopilot host cannot be rapidly reduced well by using the gas in the passenger compartment, so that the temperature of the autopilot host needs to be reduced first, and then the reduced gas flows through the autopilot host, so that the temperature of the autopilot host is effectively adjusted. When the air in the passenger compartment is cooled, the illumination intensity, the ambient temperature and the current vehicle speed at the current moment can be acquired according to the collector in the vehicle, the preset refrigeration demand parameter table is searched, and the refrigeration demand corresponding to the illumination intensity, the ambient temperature and the current vehicle speed at the current moment is acquired. After the refrigeration requirement is obtained, the air conditioning box can be controlled to work with corresponding intensity, so that the temperatures of the passenger cabin and the automatic driving host are effectively controlled.
According to the technical scheme, the temperature of the automatic driving host is obtained, when the temperature of the automatic driving host is larger than a first temperature threshold value, whether the temperature of the air inlet of the host is larger than a second temperature threshold value or not is judged, if the temperature of the air inlet of the host is larger than the second temperature threshold value, the refrigeration requirement is determined according to the illumination intensity, the ambient temperature and the current vehicle speed, and the air conditioning box is controlled to operate according to the refrigeration requirement. The problem of a large amount of heats that produce in the automatic driving host computer working process can not in time scatter and disappear, the incident takes place easily is solved, can utilize the air flow to reduce the temperature of automatic driving host computer by the great limit, under the prerequisite that does not influence passenger cabin temperature, utilize passenger cabin gas to cool down for automatic driving host computer, realized energy saving and emission reduction's effect.
EXAMPLE III
Fig. 5 is a flowchart of a vehicle cold air control method according to a second embodiment of the present invention. The present embodiment further optimizes the vehicle cool air control method on the basis of the above-described embodiments.
As shown in fig. 5, the method specifically includes:
and step 201, acquiring the temperature of the automatic driving host.
Specifically, whether the temperature of the automatic driving host is greater than a first temperature threshold value is judged, and if yes, step 203 is performed; otherwise, returning to step 201 to perform the next round of value determination again.
Specifically, it is determined whether the temperature of the air inlet of the host is greater than the second temperature threshold, and if so, step 205 is performed; otherwise, go to step 204.
Specifically, when the temperature of the air inlet of the host is not greater than the second temperature threshold value, the temperature of the air in the vehicle passenger compartment can be considered to be low, and at the moment, the host cooling fan can be started, so that the air in the vehicle passenger compartment flows through the automatic driving host to cool the automatic driving host. In addition, after the host cooling fan is started, the temperature of the automatic driving host can be monitored in real time, and when the temperature of the automatic driving host is reduced to the safe temperature, the host cooling fan can be controlled to stop working.
Alternatively, the speed of the main engine cooling fan may be increased as the temperature of the main engine air inlet increases. Fig. 6 is a schematic diagram illustrating a relationship between temperatures of a host cooling fan and a host air inlet in a vehicle cold air control method according to a third embodiment of the present invention. As shown in fig. 6, in a certain value range, the greater the temperature of the air inlet of the main machine is, the greater the rotation speed of the cooling fan of the main machine is.
And step 205, acquiring the illumination intensity, the ambient temperature and the current vehicle speed, and searching for the corresponding refrigeration demand by combining a preset refrigeration demand parameter table.
The refrigeration demand parameter table can be understood as a relational mapping table for recording the corresponding relation between the illumination intensity, the ambient temperature, the current vehicle speed and the refrigeration demand.
Specifically, when the temperature of the air inlet of the host is greater than the second temperature threshold, the temperature of the air in the passenger cabin is considered to be higher, and the temperature of the automatic driving host can not be well reduced by utilizing the gas in the passenger cabin, so that the temperature of the automatic driving host needs to be reduced firstly, and then the reduced gas flows through the automatic driving host, so that the temperature of the automatic driving host is effectively adjusted. When the air in the passenger compartment is cooled, the illumination intensity, the ambient temperature and the current vehicle speed at the current moment can be acquired according to the collector in the vehicle, the preset refrigeration demand parameter table is searched, and the refrigeration demand corresponding to the illumination intensity, the ambient temperature and the current vehicle speed at the current moment is acquired.
The following table can be a part of a refrigeration demand parameter table calibrated for a certain vehicle type, and different refrigeration demands are correspondingly met by different illumination intensities, environment temperatures and current vehicle speeds.
And step 206, judging whether the refrigeration demand is less than or equal to a preset demand threshold value.
Specifically, after the refrigeration demand required at the current moment is obtained, whether the refrigeration demand is less than or equal to a preset demand threshold value or not can be judged, and if yes, step 208 is performed; otherwise, go to step 207.
And step 207, controlling the automatic driving host to stop working, and carrying out corresponding alarm prompt.
Specifically, when the refrigeration demand is greater than the preset demand threshold value, the vehicle can be considered to be running under extremely hot weather conditions, and if the automatic driving host machine is enabled to continuously work at the moment, potential safety hazards may exist, so that the automatic driving host machine needs to be controlled to suspend working, corresponding alarm prompt is carried out, a driver or a passenger is prompted to carry out troubleshooting, and the potential safety hazards are eliminated.
And step 208, controlling the blower to operate according to the refrigeration requirement.
Specifically, after the refrigeration requirement is obtained, the air conditioning box can be controlled to work with corresponding strength, so that the temperatures of the passenger cabin and the automatic driving host are effectively controlled.
And step 209, judging whether the environmental temperature is greater than a third temperature threshold value.
The third temperature threshold may be calibrated in advance according to a specific vehicle type, and the third temperature threshold may be smaller than the second temperature threshold, for example, the third temperature threshold is set to 28 ℃ in advance.
Specifically, it is determined whether the ambient temperature is greater than a third temperature threshold, and if so, step 210 is performed; otherwise, step 203 may be returned to.
And step 210, controlling the evaporator to operate.
Specifically, when the ambient temperature is greater than the third temperature threshold, the temperature of the passenger compartment cannot be effectively reduced only by operating the blower, and therefore the evaporator needs to be controlled to operate to cool the passenger compartment.
And step 211, acquiring the temperature in the cabin, and judging whether the temperature in the cabin is smaller than a fourth temperature threshold value.
Specifically, the temperature in the cabin may be obtained according to a temperature sensor in the passenger cabin, and whether the temperature in the cabin is smaller than a fourth temperature threshold is monitored in real time, for example, whether the temperature in the cabin is smaller than 25 ℃ is judged, and if yes, step 212 is performed; otherwise, step 203 may be returned to.
And step 212, controlling the evaporator and the blower to stop running.
Specifically, when the cabin temperature is lower than the fourth temperature threshold, it can be indicated that the temperature of the passenger cabin is in the passenger comfort temperature range, and the evaporator and the blower can be controlled to stop working in sequence for the purpose of energy saving.
According to the technical scheme, the temperature of the automatic driving host is obtained, when the temperature of the automatic driving host is larger than a first temperature threshold value, whether the temperature of a host air inlet is larger than a second temperature threshold value or not is judged, if the temperature of the host air inlet is not larger than the second temperature threshold value, a host cooling fan is started to cool the automatic driving host, if the temperature of the host air inlet is larger than the second temperature threshold value, the refrigeration requirement is determined according to the illumination intensity, the ambient temperature and the current vehicle speed, the refrigeration requirement is smaller than or equal to a preset requirement threshold value, an air blower operates according to the refrigeration requirement, and an evaporator is controlled to operate simultaneously when the ambient temperature is larger than a third temperature threshold value, when the refrigeration requirement is larger than the preset requirement threshold value, the automatic driving host is controlled to stop working, and corresponding alarm prompt is carried out. The problem of a large amount of heats that produce in the automatic driving host computer working process can not in time scatter and disappear, the incident takes place easily is solved, can utilize the air flow to reduce the temperature of automatic driving host computer by the great limit, under the prerequisite that does not influence passenger cabin temperature, utilize passenger cabin gas to cool down for automatic driving host computer, realized energy saving and emission reduction's effect.
