[0039] In the following description, specific details such as particular system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0040] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.
[0041] The vehicle control method of the embodiments of the present invention is primarily applicable to hybrid vehicles. Due to the electric drive system, the vehicle's low-voltage power supply has been transformed from a traditional uncontrollable power source to a controllable DC-DC (direct current converter) power source. Furthermore, hybrid vehicles generally use a wide range of 6.5V to 16V components when selecting automotive electronic components. The power of the actuators within the transmission has a linear relationship with the operating voltage: the higher the supply voltage, the greater the output power. Therefore, the embodiments of the present invention utilize the adjustable DC-DC supply voltage in hybrid vehicles and the fact that the output power of the transmission actuators increases with increasing supply voltage, thereby reducing the cost of selecting actuators for hybrid transmissions.
[0042] Pure electric vehicles generally do not have a transmission and are therefore not suitable for transmission control using this method. However, this method can be used to control other actuators in the vehicle that require power reserves.
[0043] Figure 1 This is a schematic diagram of the implementation flow of the vehicle control method provided by the embodiment of the present invention. Figure 1 As shown, the vehicle control method includes the following steps:
[0044] Step S101, when it is detected that the vehicle is in a preset operating condition, the output voltage of the DC converter that supplies power to the target actuator is controlled to increase from a rated value to a first preset value, and the target actuator is controlled to perform a corresponding action; wherein the preset operating condition is a condition that requires the target actuator to output high power.
[0045] In this embodiment, taking the actuator in the transmission as an example, the TCU (Transmission Control Unit) can communicate directly or indirectly with the DCDC. When the TCU determines that there is a potential component with high power usage demand, the DCDC is requested to increase the power supply voltage for a period of time to achieve an instantaneous usage environment that exceeds the rated peak power for the transmission actuator.
[0046] For example, the TCU determines based on internal logic whether there is a self-learning or mechanical jamming attempt to punch the card, or other working conditions that require the actuator to output high power instantaneously. If so, the TCU requests the DCDC to control the output voltage to increase to the first preset value U1. After receiving the request, the DCDC adjusts the target operating voltage to U1.
[0047] The communication method between the TCU and the DCDC is not limited. For example, the TCU can directly send a request to the DCDC, or the TCU can indirectly request the DCDC through an ECU (Electronic Control Unit) such as a VCU (Vehicle Control Unit) or a gateway.
[0048] Step S102: detecting the action execution status of the target actuator.
[0049] In this embodiment, the TCU may determine whether the actuator completes the execution action through internal logic.
[0050] Step S103: If the action is completed, the output voltage of the DC converter is controlled to return to the rated value.
[0051] In this embodiment, the DC-DC supply voltage can only be temporarily increased to cause the transmission actuator to operate at a power level exceeding its rated peak power. After the actuator completes the corresponding action, the DC-DC supply voltage must be restored to its pre-boost value to prevent damage to the actuator due to prolonged operation exceeding its rated peak power. Therefore, in this embodiment, completion of an action includes either the actuator successfully executing the corresponding action or the actuator failing to execute the action. That is, regardless of whether the actuator's action succeeds or fails, the request is considered complete. Exemplary reasons for the actuator's failure to execute the corresponding action include a malfunction of the actuator itself, or a failure in the DC-DC boost voltage to provide the actuator with the required power to execute the action.
[0052] As can be seen, when the embodiment of the present invention detects that a target actuator (such as a transmission actuator) requires high power output, it temporarily increases the output voltage of the DC converter powering the actuator from the rated value to a first preset value, thereby providing the actuator with an instantaneous operating environment exceeding the rated peak power, enabling the actuator to perform the corresponding action. This approach eliminates the need to reserve excessive power reserves when selecting an actuator, reduces the peak power requirements, and reduces the cost of selecting an actuator.
[0053] As a possible implementation, in step S101, controlling the target actuator to perform a corresponding action can be described in detail as follows:
[0054] In the process of controlling the output voltage of a DC converter that supplies power to a target actuator to increase from a rated value to a first preset value, if the output voltage of the DC converter reaches a second preset value, the target actuator is controlled to perform a corresponding action; wherein the second preset value is not greater than the first preset value.
[0055] In this embodiment, after the TCU issues a voltage boost request and the DCDC and other components respond, the vehicle low voltage level will experience a momentary surge phenomenon, see Figure 2 As shown, a brief, transient voltage pulse occurs between the DC-DC output voltage and the 12V battery. Considering the time delay between the TCU controlling the actuator's actions, this method sets a second preset value, U2 (U2 <= U1; the specific value can be set based on actual needs), to ensure the actuator operates during voltage surges. When the TCU detects that the supply voltage is greater than U2, it requests the actuator to operate at its highest power, accommodating the time difference between voltage rise detection and actuator action.
[0056] As a possible implementation, before controlling the output voltage of the DC converter that supplies power to the target actuator to be increased from a rated value to a first preset value, the method further includes:
[0057] Control other low-voltage electrical devices connected to the DC converter except the target actuator to temporarily reduce the operating power;
[0058] Reducing the operating power includes: directly shutting down other low-voltage electrical devices or reducing the operating power of other low-voltage electrical devices to the lowest operating power that can maintain the current working state.
[0059] In this embodiment, the DCDC output voltage is determined by the DCDC output power and the power consumption of the external components. When the DCDC output power is greater than the power consumption of the external components, the DCDC output voltage is determined by the DCDC; when the DCDC output power is less than the power consumption of the external components, the DCDC output voltage is adjusted from the external 12V battery clamp to the battery float voltage. In order to successfully increase the DCDC output voltage to the first preset value, other low-voltage electrical devices connected to the DC converter, such as the VCU and other low-voltage (12V) electrical appliance control units, can be controlled to reduce power to the current minimum required working power or shut down according to the current working state, thereby providing the necessary conditions for DCDC to boost the voltage. When the actuator completes the action, the DCDC output voltage returns to the rated value, and other low-voltage electrical devices return to their original power operation.
[0060] As a possible implementation, in step S101, the output voltage of the DC converter that supplies power to the target actuator is controlled to increase from a rated value to a first preset value, which can be described in detail as follows:
[0061] Sending a boost command to the DC converter and performing timing;
[0062] If the output voltage of the DC converter reaches a first preset value within a preset time, the voltage boost is determined to be successful; otherwise, the voltage boost is determined to be failed;
[0063] After the boost fails, the output voltage of the control target actuator is restored to the rated value.
[0064] In this embodiment, the voltage may not be boosted due to DCDC hardware limitations or interference from vehicle electrical appliances. After the TCU requests a voltage boost, a counter counts T1. If the timer exceeds a preset time and the DCDC output voltage has not reached a first preset value U1, the voltage boost is determined to have failed.
[0065] In the scenario of boost failure, if the output voltage of the DCDC does not reach the second preset value U2, the actuator will not perform the corresponding action; if the output voltage of the DCDC reaches the second preset value U2, the actuator will perform the corresponding action but may fail to perform the action because the required power cannot be achieved.
[0066] If boost fails, the TCU directly requests the DCDC to stop boosting, or indirectly requests it through an ECU like the VCU, and clears timer T1. Upon receiving the TCU's direct or indirect request to stop boosting, the DCDC adjusts its output target voltage to the pre-boost operating voltage. Simultaneously, the VCU and other components restore the control logic prior to the boost control interruption and request the low-voltage components to operate at their original logic state.
[0067] As a possible implementation method, after the target executor fails to execute the corresponding action, it also includes:
[0068] A reminder message is sent to the user through the vehicle's display screen that the preset working condition has not been completed.
[0069] In this embodiment, if the target actuator fails to perform its corresponding action, such as transmission adaptive learning, transmission jamming, or other operating conditions, a prompt can be provided via the vehicle's central control screen, instrument panel, speakers, or other devices, allowing the user to identify and eliminate the fault, thereby ensuring vehicle safety and reliability. Failure causes include DC-DC boost failure and actuator failure.
[0070] In combination with the above, in one embodiment, see Figure 3 As shown, the detailed steps of the vehicle control method can be as follows:
[0071] Step 1: The TCU determines based on internal logic whether there is a need for the actuator to output high power instantaneously, such as self-learning or mechanical jamming and card punching attempts.
[0072] Step 2: When the TCU determines that future control requires a higher actuator output power, it directly requests the DC-DC converter (or indirectly requests the DC-DC converter through an ECU such as the VCU or gateway) to increase the output voltage to a first preset value, U1. Simultaneously, the TCU starts timer T1.
[0073] Step 3: After receiving the voltage boost request, the DCDC adjusts the target operating voltage to U1. Upon receiving the TCU request, the VCU and other low-voltage (12V) electrical control units reduce power to the minimum required operating power or shut down based on their current operating status, thus ensuring the DCDC voltage boost is sufficient.
[0074] Step 4: After the TCU issues a voltage boost request and the DCDC and other components respond, the vehicle's low-voltage level experiences a momentary surge, a brief, transient voltage pulse between the DCDC output voltage and the 12V battery. When the TCU detects that the supply voltage is greater than U2 (U2 <= U1), it requests the actuator to operate at maximum power to accommodate the time difference between voltage rise detection and actuator actuation.
[0075] Step 5: The TCU actuator performs the action.
[0076] Step 6: The TCU uses internal logic to determine whether the executor has completed the action. If the action is determined to be successful or failed, the request is considered completed.
[0077] Step 7: The TCU requests to stop the boost state and clears the timer T1.
[0078] Step 8: When the DCDC receives the request to stop boosting, it adjusts the output target voltage to the operating voltage before the boost. At the same time, the VCU and other components restore the control logic before the boost control interruption and request the low-voltage components to operate in the original logic state.
[0079] In general, the embodiments of the present invention have the following advantages:
[0080] (1) If the internal actuator of the TCU takes into account both the peak power demand and the reliability demand, the cost will increase significantly. For example, by combining the universal characteristics of the vehicle electrical wide voltage with this method, the transient high power characteristics of the actuator under high voltage can be used to reduce the peak power selection demand of the actuator. This can reduce the peak power requirement in the selection of hybrid TCU actuators and thus reduce costs.
[0081] (2) Setting dual thresholds of U1 and U2 to adapt to the time difference between monitoring and execution and improve the feasibility of the solution.
[0082] (3) The embodiment of the present invention improves control robustness by using the VCU to send requests unidirectionally, using the actual execution status (low voltage) as a feedback signal and a simple interactive form of timeout determination.
[0083] As a further improvement, in one embodiment, considering that the power required by the actuator under different preset working conditions is different, different first preset values and second preset values can be set according to different preset working conditions to achieve more precise control. In this solution, the vehicle control method is:
[0084] When it is detected that the vehicle is in a preset operating condition, the output voltage of the DC converter that supplies power to the target actuator is increased from a rated value to a first preset value corresponding to the preset operating condition, and the target actuator is controlled to perform a corresponding action; wherein the preset operating condition is an operating condition requiring the target actuator to output high power;
[0085] Detect the action execution status of the target actuator;
[0086] If the action is completed, the output voltage of the DC converter is controlled to return to the rated value.
[0087] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
