Abstract
Description
Technical Field
[0001] The present invention relates to the field of engines, and more specifically, to a method for setting the entry and exit of an induction system. Background Art
[0002] Heavy-duty emission regulations require that "the emission control detection system can operate under the following conditions: 1. Ambient temperature from 266K to 311K (-7 to 38°C); 2. Altitude below 2500 km; 3. Engine coolant temperature higher than 343K (70°C)".
[0003] For the activation and exit of the induction system, it is possible to choose whether to use enabling conditions. After choosing to use the enabling conditions, both entering and exiting the induction system need to meet this enabling condition. The current enabling condition is that the atmospheric pressure is higher than the limit value; and the ambient temperature is within the maximum and minimum range; and the coolant temperature is greater than the limit value, and all three conditions need to be met simultaneously.
[0004] When choosing to use the induction enabling conditions (altitude, ambient temperature, coolant temperature), the induction system will only be activated after the enabling conditions are met. However, when exiting the induction, the enabling conditions also need to be met, resulting in a phenomenon of delayed recovery of the induction. For example, when a fault in the induction system is activated after meeting the induction enabling conditions, the driver alarm light will be lit, and after a certain period of time, torque limitation or even speed limitation will be activated. But when the fault that activated the induction is restored, since the induction enabling conditions are not met (coolant temperature is lower than 70°C), the driver alarm light will not go out, and the torque limitation and speed limitation will not be exited. This phenomenon of delayed exit of the induction is not conducive to the customer's usage experience. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a method for setting the entry and exit of an induction system in view of the deficiencies of the prior art, and solve the technical problem that the existing induction enabling conditions have the phenomenon of delayed exit of the induction, which is not conducive to the customer's usage experience.
[0006] A method for setting the entry and exit of an induction system according to the present invention is as follows: obtain the state of the activated induction system and the state of the induction timer, set a second enabling condition, set a first enabling condition according to the state of the activated induction system and the state of the induction timer, and enter the induction system when the second enabling condition is met or the first enabling condition is met; exit the induction system when the second enabling condition is not met or the first enabling condition is not met.
[0007] For further improvement, the method for setting the first enabling condition is as follows
[0008] Take the states of the activation induction system and the induction timer as two input variables of the state machine respectively, and set the trigger condition for the state machine to output 1 as the existence of a fault in the activation induction system or the induction timer not being cleared;
[0009] When the state machine determines that there is a fault in the activation induction system or the induction timer is not cleared, the state machine outputs 1 and enters the induction system simultaneously; otherwise, the state machine outputs 0 and exits the induction system simultaneously;
[0010] Take the existence of a fault in the activation induction system or the induction timer not being cleared as the first enabling condition.
[0011] Furthermore, the second enabling condition includes determining that the vehicle is at a low altitude, the ambient temperature of the vehicle is within the appropriate ambient temperature range, and the coolant temperature is at a high coolant temperature.
[0012] Even further, the method for determining that the vehicle is at a low altitude is as follows:
[0013] Set a second determination time, obtain the real-time altitude of the vehicle, and when the real-time altitude of the vehicle is less than the preset altitude limit value, the second determination time starts to count; when the second determination time ends, if the real-time altitude of the vehicle is still less than the preset altitude limit value, it is determined that the vehicle is at a low altitude.
[0014] Even further, the method for determining that the ambient temperature of the vehicle is within the appropriate ambient temperature range is as follows:
[0015] Set a second determination time, obtain the real-time ambient temperature of the vehicle, and when the real-time ambient temperature of the vehicle is within the preset appropriate ambient temperature range, the second determination time starts to count; when the second determination time ends, if the real-time ambient temperature of the vehicle is still within the preset appropriate ambient temperature range, it is determined that the ambient temperature of the vehicle is within the appropriate ambient temperature range.
[0016] Even further, the method for determining that the coolant temperature is at a high coolant temperature is as follows:
[0017] Set a third determination time, obtain the real-time coolant temperature of the vehicle, and when the real-time coolant temperature is greater than the preset coolant temperature limit value, the third determination time starts to count; when the third determination time ends, if the real-time coolant temperature is still greater than the coolant temperature limit value, it is determined that the coolant temperature is at a high coolant temperature.
[0018] Further, obtain the test value of the input vehicle. When the test value is the same as the preset calibrated value, shield the second enabling condition and the first enabling condition. When it is not necessary to meet the second enabling condition or the first enabling condition, the induction system can be entered.
[0019] Beneficial effects
[0020] The advantages of the present invention are as follows:
[0021] The present invention obtains the state of the activation induction system and the state of the induction timer, sets the second enabling condition, and sets the first enabling condition according to the state of the activation induction system and the state of the induction timer. When the second enabling condition is met or the first enabling condition is met, the induction system is entered; when the second enabling condition is not met and the first enabling condition is not met, the induction system is exited, realizing that it is not necessary to meet the second enabling condition when exiting the induction system, avoiding the phenomenon of delayed exit from the induction, and improving the customer's usage experience. Description of the drawings
[0022] Figure 1 It is a flowchart of the setting method for entering and exiting the induction system of the present invention. Detailed implementation manners
[0023] The following describes the present invention in further detail with reference to embodiments, but it does not constitute any limitation to the present invention. Any limited modifications made by anyone within the scope of the claims of the present invention are still within the scope of the claims of the present invention.
[0024] Refer to Figure 1 , a setting method for entering and exiting the induction system of the present invention. The method is to obtain the state of the activation induction system and the state of the induction timer, set the second enabling condition, and set the first enabling condition according to the state of the activation induction system and the state of the induction timer. When the second enabling condition is met or the first enabling condition is met, the induction system is entered. When the second enabling condition is not met or the first enabling condition is not met, the induction system is exited.
[0025] The method for setting the first enabling condition is
[0026] Respectively use the state of the activation induction system and the state of the induction timer as the two input quantities of the state machine, and set the trigger condition for the state machine output to be equal to one as the existence of a fault in the activation induction system or the induction timer not being cleared.
[0027] When the state machine determines that there is a fault in the activation induction system or the induction timer is not cleared, the state machine output is equal to one, and at the same time, the induction system is entered; otherwise, the state machine output is equal to zero, and at the same time, the induction system is exited.
[0028] Set up a state machine to identify whether there is a fault in the activation induction system or the induction timer has not been cleared in the current system.
[0029] Take the existence of a fault in the activation induction system or the induction timer not being cleared as the first enabling condition.
[0030] The second enabling condition includes determining that the vehicle is at a low altitude, the ambient temperature of the vehicle is within the appropriate ambient temperature range, and the coolant temperature is at a high coolant temperature.
[0031] The method for determining that the vehicle is at a low altitude is as follows:
[0032] Set a second determination time, obtain the real-time altitude of the vehicle. When the real-time altitude of the vehicle is less than the preset altitude limit value, the second determination time starts to count; when the second determination time ends, if the real-time altitude of the vehicle is still less than the preset altitude limit value, it is determined that the vehicle is at a low altitude.
[0033] The method for determining that the ambient temperature of the vehicle is within the appropriate ambient temperature range is as follows:
[0034] Set a second determination time, obtain the real-time ambient temperature of the vehicle. When the real-time ambient temperature of the vehicle is within the preset appropriate ambient temperature range, the second determination time starts to count; when the second determination time ends, if the real-time ambient temperature of the vehicle is still within the preset appropriate ambient temperature range, it is determined that the ambient temperature of the vehicle is within the appropriate ambient temperature range.
[0035] The method for determining that the coolant temperature is at a high coolant temperature is as follows:
[0036] Set a third determination time, obtain the real-time coolant temperature of the vehicle. When the real-time coolant temperature is greater than the preset coolant temperature limit value, the third determination time starts to count; when the third determination time ends, if the real-time coolant temperature is still greater than the coolant temperature limit value, it is determined that the coolant temperature is at a high coolant temperature.
[0037] Obtain the test value input to the vehicle. When the test value is the same as the preset calibrated quantity, the second enabling condition and the first enabling condition are masked. When it is not necessary to meet the second enabling condition or the first enabling condition, the induction system can be entered.
[0038] This solution can meet the requirement that when there is a fault in the induction system or there is no fault in the induction system but the torque limit or speed limit has been activated, even if the second enabling condition is not met, the induction system can be entered and the induction system can be exited normally.
[0039] Meanwhile, it can also meet the requirement that when not entering the induction system, the second enabling condition required by regulations can be directly used to enter the induction system, activate the induction according to the fault, and realize that there is no need to meet the second enabling condition when exiting the induction system, avoiding the phenomenon of delayed exit from the induction and improving the customer experience.
[0040] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which will not affect the implementation effect of the present invention and the practicability of the patent.
