[0032] This embodiment provides a vehicle control method for an electronic device running on the vehicle. Figure 2 is a flow chart of a vehicle control method according to one embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0033] Step S10, acquiring temperature information, the temperature information including a first temperature and a first temperature threshold, the first temperature being a temperature value of the transmission lubricating oil, and the first temperature threshold being determined according to a type of the transmission lubricating oil;

[0034] Step S20, obtaining time information, the time information including a first duration and a first time threshold, the first duration being the speed stabilization time of the engine at low temperature starting, and the first time threshold being determined according to the initial temperature of the engine coolant;

[0035] Step S30, generating a target control instruction set based on the temperature information and the time information;

[0036] Step S40, based on the target control instruction, controls the clutch to execute a preset action, and controls the engine to enter a preset starting mode, wherein the preset action includes at least one of the following: clutch disengagement, clutch engagement, and the preset starting mode includes at least one of the following: a conventional starting mode, a low temperature starting preparation mode.

[0037] The normal starting mode is also the starting mode under non-low temperature conditions.

[0038] The low-temperature start preparation mode means that the vehicle determines the low-temperature start mode, but still needs the low-temperature start enable signal (or enable signal) issued by the controller to start the start process.

[0039] Through the above steps, it is possible to achieve a method of generating a target control instruction set based on temperature information and time information, and to control the clutch to execute a preset action based on the target control instruction, and to control the engine to enter a preset starting mode, thereby achieving control of the clutch, eliminating the starting resistance caused by the transmission during low-temperature starting, and determining the vehicle control strategy according to the first temperature, thereby solving the technical problem of the difficulty in starting an automatic transmission vehicle in a low-temperature environment.

[0040] like Figure 3 A module schematic diagram of a vehicle control system is shown. The vehicle components and signals involved in the starting method of the present application include an engine 11, a clutch 12, a transmission 13, a transmission control unit 14, an engine start request signal 15, a transmission lubricating oil temperature signal 16, an engine speed signal 17, a clutch position signal 18, a clutch control signal 19, and a low temperature start allowance signal 20.

[0041] Optionally, in step S40, generating a target control instruction set based on the temperature information and the time information includes the following execution steps:

[0042] Determining whether the first temperature is less than a first temperature threshold;

[0043] If yes, generating a first target control instruction in the target control instruction set, the first target control instruction being used to control the engine to enter a low temperature start preparation mode;

[0044] If not, a second target control instruction in the target control instruction set is generated, and the second target control instruction is used to control the engine to enter a normal starting mode.

[0045] The starting mode of the engine is determined according to the first temperature, so that the vehicle control takes the lubricating oil temperature signal into consideration, the control is more precise and the control is more in line with the actual working conditions.

[0046] Optionally, generating a target control instruction set based on the temperature information and the time information further includes:

[0047] In response to the engine being in the low-temperature starting preparation mode, a third target control instruction in the target control instruction set is generated, and the third target control instruction is used to control the clutch to perform a clutch release action.

[0048] Optionally, generating a target control instruction set based on the temperature information and the time information further includes:

[0049] After detecting that the clutch is disengaged, a low-temperature start enable signal is generated, and the low-temperature start enable signal is used to control the engine to execute a preset low-temperature start process;

[0050] Determine whether the first duration is greater than a first time threshold;

[0051] If yes, a fourth target control instruction in the target control instruction set is generated, and the fourth target control instruction is used to control the clutch to perform a clutch engagement action.

[0052] Optionally, generating a target control instruction set based on the temperature information and the time information further includes:

[0053] When the engine start request signal is detected, it is determined whether the first temperature is less than a first temperature threshold.

[0054] Optionally, controlling the clutch to perform a clutch engagement action includes:

[0055] During the clutch engagement process, the clutch engagement rate is controlled to be V, where 0.6mm / s≥V≥0.3mm / s.

[0056] The clutch engagement rate of change limits the clutch engagement speed. By slowly engaging the clutch, the engine can be prevented from stalling. The impact degree is an indicator for evaluating the smoothness of the clutch engagement process during gear shifting, which can be reflected in the rate of change of the vehicle's longitudinal acceleration. The impact degree is only related to the clutch torque change rate. By limiting the clutch torque change rate, the impact degree during clutch shifting can also be reduced.

[0057] Optionally, controlling the clutch to perform a clutch disengagement action includes:

[0058] During the clutch disengagement process, the clutch is controlled to be disengaged at the maximum disengagement capacity, that is, the clutch should be disengaged quickly to reduce clutch wear.

[0059] Specifically, the first temperature threshold needs to be determined according to the transmission lubricant type. The first time threshold needs to be determined according to the engine coolant temperature.

[0060] Figure 4 FIG. 1 is a flow chart of a vehicle control method according to an optional embodiment of the present invention. Figure 3 and Figure 4 As shown in the figure, the specific process of vehicle control start is as follows:

[0061] The transmission control unit 14 selects a reasonable clutch control strategy based on the received engine start request signal 15 and the transmission lubricating oil temperature signal 16, and controls the clutch to disengage or engage by issuing a clutch control signal 19, so as to achieve the purpose of improving the vehicle's low-temperature starting performance by controlling the clutch.

[0062] The transmission control unit 14 determines the current state of the engine and the clutch according to the received two feedback signals, namely the engine speed signal 17 and the clutch position signal 18 .

[0063] (1) In S21: the transmission control unit 14 receives the engine start request signal 15, which is sent to the transmission control unit 14 by other control units including but not limited to the engine control unit, the vehicle control unit, etc. in response to the driver's starting procedure.

[0064] (2) In step S22: determine whether the transmission lubricating oil temperature signal 16 is lower than a certain threshold temperature. The threshold temperature is determined according to the type of different transmission lubricating oils. The present invention is described by taking a typical temperature of -10°C as an example. If the oil temperature is higher than -10°C in step S22, the process proceeds to step S23, and the engine is started normally. If the oil temperature is lower than -10°C, the process proceeds to step S24, and the engine enters a low temperature start mode.

[0065] (3) In step S25: the transmission control unit 14 sends a clutch control signal 19 to control the clutch 12 to be disengaged. At this time, the engine is not started, and disengaging the clutch will not cause any impact. The clutch should be disengaged as quickly as possible.

[0066] (4) In step S26: determine whether the clutch is disengaged based on the clutch position signal 18. If the judgment result in step S26 is no, return to step S25. If the judgment result in step S26 is yes, enter step S27 and issue a low temperature starting permission signal 20 in step S27.

[0067] (5) In step S28: determine whether the engine speed stabilization time is greater than a threshold time according to the engine speed signal 17. The threshold time is specifically calibrated according to the engine coolant temperature. The present invention takes 15 seconds as an example for explanation. If the speed stabilization time is less than 15 seconds at step S28, return to step S27. If the speed stabilization time is greater than 15 seconds at step S28, proceed to step S29.

[0068] (6) In step S29: the transmission control unit 14 sends a clutch control signal 19 to control the clutch 12 to engage. At this time, the engine has been started and the clutch should be engaged slowly to avoid engine stalling.

[0069] (7) In step S30: determine whether the clutch is engaged based on the clutch position signal 18. If the judgment result in step S30 is no, return to step S29. If the judgment result in step S30 is yes, enter step S31 and the low-temperature start is completed.

[0070] Optionally, the transmission control unit 14 may be a separate transmission control unit, or may be a control unit integrated into other control units and having a transmission control function.

[0071] The oil temperature signal 16 may be a transmission lubricating oil temperature signal that directly reflects the lubricating oil temperature, or may be an ambient temperature signal that indirectly reflects the lubricating oil temperature.

[0072] In the technical solution of this application, when starting a vehicle below a threshold temperature, the clutch needs to be disengaged first to reduce the resistance caused by the transmission during starting, and the clutch is gradually engaged after successful starting. When the clutch is disengaged before starting, it should be disengaged quickly to reduce clutch wear, and when the clutch is engaged after successful starting, it should be engaged slowly to avoid engine stalling.

[0073] In order to eliminate the resistance to engine starting caused by poor fluidity of transmission lubricating oil in low temperature environment and improve the problem of difficulty in starting vehicles equipped with automatic transmission in low temperature environment, the present invention proposes a clutch intelligent control method for assisting engine low temperature starting.

[0074] In the technical solution of the present application, the transmission control unit receives an engine start request signal, a transmission lubricating oil temperature signal and other required signals. The transmission lubricating oil temperature signal can be measured by an oil temperature sensor and sent directly to the transmission control unit for processing by the transmission control unit, or it can be processed by other controllers and sent to the transmission control unit. When the transmission control unit receives a start request and determines that the engine needs to be started, it determines whether the engine is in a low-temperature start state at this time in combination with the received transmission lubricating oil temperature signal, and selects a reasonable clutch control strategy.

[0075] The present application can eliminate the starting resistance caused by the transmission during low-temperature starting by controlling the clutch, thereby further improving the starting speed of the vehicle.
