The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1, the present embodiment provides an engine low-temperature start control system that can be applied to an automatic transmission vehicle. The engine low-temperature starting control system comprises an engine 1, a clutch 2, a control unit 3 and an information acquisition unit.
The information acquisition unit is used for acquiring temperature information and rotating speed information of the engine 1, the rotating speed stabilization time of the engine 1 can be obtained according to the rotating speed information, and the control unit 3 can control the clutch 2 to be separated or combined according to the temperature information and the rotating speed stabilization time. When the temperature information is less than or equal to the temperature threshold value, the control unit 3 controls the clutch 2 to be separated, and when the rotating speed stabilizing time is greater than or equal to the time threshold value, the control unit 3 controls the clutch 2 to be combined.
In the engine low-temperature start control system provided by this embodiment, after triggering the start instruction of the engine 1, the control unit 3 first determines whether the temperature information detected by the information acquisition unit is less than or equal to the temperature threshold, if so, it indicates that the engine 1 is in a low-temperature environment and needs to enter a low-temperature start mode (if not, it indicates that the engine can be started normally according to a normal mode). After entering the low-temperature starting mode, the control unit 3 controls the clutch 2 to be disengaged (at this time, the engine 1 is not started), after the clutch 2 is disengaged, the control unit 3 judges whether the rotational speed stabilization time of the engine 1 is greater than or equal to the time threshold value or not according to the rotational speed information of the engine 1, if so, the engine 1 can be started at the low temperature, and the control unit 3 controls the clutch 2 to be combined, so that the engine 1 is started completely (if not, the rotational speed stabilization time is required to reach the time threshold value).
Alternatively, referring to fig. 1, the engine low-temperature start control system further includes a transmission 4, and the temperature information is lubricating oil temperature information of the transmission 4. Because the fluidity of the lubricating oil is poor in a low-temperature environment, the starting resistance of the engine 1 can be increased, and the starting of the engine 1 is directly influenced, so that whether the engine 1 needs to be started at a low temperature can be directly reflected by detecting the temperature of the lubricating oil of the transmission 4, and the control is more accurate.
In other embodiments, the temperature information may also be information of an ambient temperature of the engine 1, and the temperature of the lubricant of the transmission 4 can be indirectly reflected by detecting the ambient temperature of the engine 1, so that the starting of the engine 1 can be accurately controlled. It should be noted that the temperature information collected by the information collecting unit is not limited to that listed in the present embodiment, as long as the engine 1 can be accurately controlled to start in response to the temperature of the lubricating oil.
In the embodiment, the clutch 2 is separated before the engine 1 is started, so that the resistance of the transmission 4 to the engine 1 can be reduced, the engine 1 is assisted to be started in a low-temperature environment, and the starting speed of the automobile in the low-temperature environment is increased. In addition, the engine low-temperature starting control system does not need to be provided with a heating device, does not increase the installation difficulty and the hardware cost, is economical and practical, and is easy to realize the control method.
Alternatively, referring to fig. 1, the control unit 3 is a controller of the transmission 4, i.e. the control unit 3 is a controller that controls the transmission 4 individually. In other embodiments, the control unit 3 may also be a controller of the entire vehicle, that is, the control unit 3 is integrated on the entire vehicle controller, as long as the information acquired by the information acquisition unit can be received, and the clutch 2 can be controlled to be disengaged or engaged according to the corresponding information.
Referring to fig. 1, in this embodiment, the information acquisition unit can also acquire clutch position information of the clutch 2, and the control unit 3 can determine the separation and combination states of the clutch 2 according to the clutch position information. When the clutch position information collected by the information collecting unit is separation, the separation of the clutch 2 is completed, and when the clutch position information collected by the information collecting unit is combination, the combination of the clutch 2 is completed.
Alternatively, the information acquisition unit includes a temperature sensor for measuring the temperature of the lubricating oil of the transmission 4 or the temperature of the environment in which the engine 1 is located, a rotation speed sensor for measuring the rotation speed of the engine 1, a position sensor for measuring the clutch position of the clutch 2, and the like.
As shown in fig. 2, the present embodiment further provides an engine low-temperature start control method, which is applied to the engine low-temperature start control system described above, and includes the following steps:
s1, triggering a start command of the engine 1;
s2, the control unit 3 judges whether the temperature information is less than or equal to the temperature threshold value, if yes, the process goes to S4, and if not, the process goes to S3;
s3, enabling the engine 1 to enter a normal starting mode;
s4, the engine 1 enters a low-temperature starting mode, and the control unit 3 controls the clutch 2 to be separated;
s5, judging whether the clutch 2 is completely separated, if so, entering S6, otherwise, returning to S4;
s6, allowing the engine 1 to start at a low temperature;
s7, judging whether the rotating speed stable time is larger than or equal to the time threshold, if so, entering S8, otherwise, returning to S6;
s8, the control unit 3 controls the clutch 2 to be combined;
s9, it is determined whether or not the engagement of the clutch 2 is completed, and if so, the start of the engine 1 is completed, otherwise, the process returns to S8.
In step S2, when the collected temperature information is the temperature of the lubricant of the transmission 4, the temperature threshold is calibrated according to the type of the lubricant of the transmission 4. In this embodiment, the typical temperature of the lubricating oil is taken as-10 ℃, and if it is determined in step S2 that the temperature of the lubricating oil is equal to or lower than-10 ℃, the operation proceeds to step S4, the engine 1 enters the low-temperature start mode, and the control unit 3 controls the clutch 2 to be disengaged so as to reduce the resistance of the transmission 4 at the start of the engine 1, thereby assisting the start of the engine 1. If the temperature of the lubricating oil is judged to be higher than-10 ℃ in the step S2, the operation goes to a step S3, and the engine 1 enters a normal starting mode and can be started normally.
In other embodiments, if the collected temperature information is the ambient temperature of the engine 1, the temperature threshold is calibrated according to the ambient temperature, and when the ambient temperature is less than or equal to the temperature threshold, it indicates that the engine 1 needs to be started at a low temperature.
In step S7, the time threshold is calibrated based on the temperature of the coolant of the engine 1. In this embodiment, the time threshold is 15S, and if it is determined in step S7 that the speed stabilization time is less than or equal to 15S, the process returns to step S6 until the speed stabilization time reaches 15S, and the clutch 2 is controlled to engage to prevent the engine 1 from starting and stalling. If it is determined in step S7 that the rotational speed stabilization time is longer than 15S, the routine proceeds to step S8, and the control unit 3 controls the clutch 2 to engage, thereby completing the start of the engine 1.
In step S4, when the clutch 2 is disengaged, the engine 1 is not started and the clutch 2 is disengaged at the speed a. In step S8, when the clutch 2 is engaged, the engine 1 is started, and the clutch 2 is engaged at a speed b that is much smaller than the speed a. That is, the clutch 2 should be disengaged at the fastest speed, and the clutch 2 should be engaged slowly when engaged. When the clutch 2 is disengaged, the engine 1 is not started, so that the engine 1 is not impacted by the clutch 2, and the rapid disengagement of the clutch 2 is beneficial to rapidly blocking the resistance of the transmission 4 to the engine 1 and improving the starting speed of the engine 1. While the engine 1 is already started when the clutch 2 is engaged, slowly engaging the clutch 2 can avoid stalling of the engine 1.
In steps S5 and S9, the control unit 3 determines whether the clutch 2 is completely disengaged or engaged by determining the clutch position information collected by the information collection unit.
The embodiment also provides an automobile which is controlled by adopting the engine low-temperature starting control method. Through reasonable control of the clutch 2, the clutch 2 is separated before the engine 1 is started, and resistance of the transmission 4 to the engine 1 can be reduced, so that the engine 1 is assisted to be started in a low-temperature environment, and the starting speed of the automobile in the low-temperature environment is effectively increased.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments illustrated herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
