Detailed Description
The present application will be described in detail with reference to the drawings and specific embodiments, wherein like reference numerals are used for similar or identical parts in the drawings or description, and implementations not shown or described in the drawings are known to those of ordinary skill in the art. In the description of the present application, the terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, an embodiment of the present application provides a control device 10, which may include a processing module 11 and a storage module 12. The memory module 12 stores therein a computer program that, when executed by the processing module 11, enables the control device 10 to execute the respective steps in the below-described automobile power saving control method.
In this embodiment, the control device 10 may be a device formed by conventional hardware modules existing in an automobile. For example, the processing module 11 and the storage module 12 may exist independently or may be integrated. For example, the processing module 11 and the memory module 12 are integrated as a controller of a vehicle. That is, a vehicle control unit on the vehicle may function as the control device 10 to execute each step in the vehicle power saving control method.
The embodiment of the application further provides an automobile, which can comprise an automobile body and the control device 10, wherein the control device 10 is arranged on the automobile body. The vehicle may be, but is not limited to, a pure electric vehicle, a hybrid electric vehicle, or the like.
Referring to fig. 2, the present application further provides a power saving control method for an automobile, which can be applied to the control device 10, and the control device 10 executes or implements the steps of the method. The automobile power saving control method can comprise the following steps:
and 120, when the electric quantity parameter is smaller than or equal to a specified value, controlling the vehicle to run in the super power saving mode according to a preset control strategy, wherein in the super power saving mode, a power output interface on the vehicle for supplying power to external equipment is in a disconnected state, and both a crawling mode and an intelligent driving system of the vehicle are in a closed state.
The following will explain the steps of the vehicle power saving control method in detail as follows:
in step 110, a trigger signal is received by the processing module 11 of the control device 10 (or a vehicle control unit in a car). The generation mode of the trigger signal can be flexibly determined according to the actual situation.
For example, the owner user may generate the trigger signal by touch control through a smart phone in wireless communication connection with the T-BOX of the vehicle by using a corresponding operation interface of APP in the smart phone. The trigger signal is then sent by the smartphone to the T-BOX, which forwards the trigger signal to the processing module 11 of the control device 10.
For another example, the vehicle owner user may directly utilize the central control display screen on the vehicle to generate the trigger signal by touch based on the virtual button of the operation interface of the central control display screen. The touch signal CAN be transmitted to the processing module 11 through the CAN bus by the central control display screen. The trigger signal is used for starting a super power saving mode of the host vehicle.
The processing module 11 may obtain a power parameter from the battery management system of the vehicle when receiving the trigger signal, where the power parameter may be obtained by sensing the battery module of the vehicle by the battery management system. The processing module 11 may determine whether the host vehicle is to enter the super power saving mode based on the power parameter. The electric quantity parameter may be a remaining electric quantity Of the battery module Of the vehicle, or a State Of Charge (SOC) value Of the battery module. The battery module is a storage battery of the vehicle and is used for supplying power to all electronic devices on the vehicle. In addition, the manner of determining the remaining capacity or SOC value of the vehicle by the battery management system is conventional, and is not described herein again.
In step 120, the specified value may be set to 20%, and 30% or the like represents the percentage of the remaining power to the full power, and may be flexibly set according to actual situations. If the electric quantity parameter is less than or equal to the designated value, the triggering condition for entering the super power saving mode is confirmed to be satisfied. At this time, the processing module 11 may control each electronic device on the vehicle by using a preset control strategy according to the trigger signal, so as to operate in the super power saving mode. The preset control strategy can be flexibly set according to actual conditions. For example, the preset control strategy may include flexibly specifying electronic devices that need to be turned off, such as cameras, radars, etc., according to the requirements.
Understandably, under the super power-saving mode, the vehicle can reduce the comfort power to the maximum extent on the premise of ensuring the safety power, thereby reducing the power consumption of the pure electric vehicle. For example, in the super power saving mode, an external power output interface of the pure electric vehicle is in an off state, and both the crawling mode and the intelligent driving system of the vehicle are in an off state.
The power output interface is an output interface which is arranged on the vehicle and used for supplying power to external equipment, and the external equipment can be flexibly determined according to actual conditions, such as an induction cooker or other electrical appliances. When the host vehicle is not in the super power-saving mode, the output interface can provide 220V of common commercial power. When the vehicle is in the super power-saving mode, the power output interface is in a disconnected state, so that power cannot be supplied to the external equipment.
Electric vehicles typically have a creep mode. After the super power saving mode is started, the processing module 11 may close the creep mode wormodo =0 of the vehicle, so that the coasting recovery brake is realized, and the power consumption of the pure electric vehicle is reduced.
In the super power saving mode, the processing module 11 may control the intelligent driving system to turn off the self-driving function service. For example, the power supply interfaces of the central computer, the driver monitoring camera (DMS), the forward-looking camera (middle distance), the forward-looking camera (long distance), the rear-looking camera, the side-looking camera, and the around-looking camera in the intelligent driving system are turned off, so that the power failure of each electronic device in the intelligent driving system is realized.
Specifically, in this embodiment, step 120 may further include a combination of one or more of the following embodiments, as follows:
in a first embodiment, step 120 may comprise:
when the vehicle is detected to be accelerated to run, controlling the running of a wheel driving motor of the vehicle according to an accelerator pedal torque output curve corresponding to the super power-saving mode, wherein in the super power-saving mode, when the accelerator pedal is at the same opening degree, a first output torque corresponding to the torque output curve is smaller than a second output torque of the vehicle in a non-super power-saving mode.
The accelerator pedal torque output curve is the corresponding relation between the opening degree of the stepped accelerator pedal and the torque of the wheel driving motor. The greater the opening degree at which the accelerator pedal is depressed, the greater the torque of the wheel drive motor, and the greater the acceleration of the vehicle. That is, the acceleration of the vehicle is positively correlated with the output torque of the wheel drive motor.
For convenience of distinction, in the super power saving mode, the accelerator pedal torque output curve may be referred to as a first torque output curve; when the vehicle is not in the super power-saving mode, the accelerator pedal torque output curve of the vehicle is called a second torque output curve. Wherein the first torque output curve is more gradual than the second torque output curve. That is, the accelerator pedal of the host vehicle corresponds to an output torque smaller in the first torque output curve than in the second torque output curve at the same opening degree. Correspondingly, the acceleration of the vehicle in the super power saving mode is smaller than the acceleration of the vehicle not in the super power saving mode. Therefore, the torque output of the accelerator pedal is stable, and the frequency of the sudden acceleration and sudden deceleration working condition is avoided, so that the power consumption of the electric automobile is reduced. Wherein, under the same opening degree, the relationship of the output torques in the first torque output curve and the second torque output curve can be as follows:
in the formula (1), T 1 The torque which is actually sent to the motor to be executed after adjustment is the torque in the first torque output curve;
T 2 the original required torque of the driver is the torque in the second torque output curve;
v denotes the actual vehicle speed;
T Drv refers to the actual torque demand of the driver or vehicle;
a. and b is an adjustment coefficient, is determined by actual vehicle calibration and part characteristics, and can be flexibly determined according to actual conditions.
In a second embodiment, step 120 may include:
when the vehicle driving mode of the vehicle is detected to be a four-wheel drive mode, the vehicle is controlled to switch the four-wheel drive mode into a two-wheel drive mode, and the vehicle is controlled to run in the two-wheel drive mode.
Understandably, if it is detected that the vehicle is currently in the four-wheel drive mode, at this time, the vehicle can be controlled to switch the four-wheel drive mode into the two-wheel drive mode. For example, in the super power saving mode, the host vehicle is controlled to travel in a rear drive mode or a front drive mode. Generally, the efficiency of the rear-drive motor is higher than that of the front-drive motor, that is, the vehicle can be controlled by default to run in a rear-drive mode, so that the power consumption of the vehicle is reduced, and the efficiency of the wheel-drive motor is improved as much as possible.
In a third embodiment, step 120 may comprise:
and when the thermal management system of the vehicle is in an operating state, controlling the thermal management system to be closed or to operate at the power corresponding to the super power-saving mode.
In the super power saving mode, the processing module 11 may control the thermal management system to directly turn off, or limit the power of components in the thermal management system, such as a PTC heater, a heat pump, a compressor, and a cooling fan, so as to reduce the comfort power to the maximum extent on the premise of ensuring the safety power, thereby reducing the power consumption of the vehicle. The power of each component in the thermal management system in the super power saving mode can be flexibly determined according to actual conditions, and is not described herein again.
In a fourth embodiment, step 120 may comprise:
and controlling a power supply interface of a specified power utilization module of the vehicle to be in a disconnected state, wherein the specified power utilization module comprises any one of an internal monitoring camera and a streaming media rearview mirror camera.
The designated power utilization module can further comprise, but is not limited to, a steering wheel heater, a charging seat, an electric color-changing sky curtain, a power socket for external connection, a vehicle door radar and an atmosphere lamp.
Understandably, in the super power saving mode, the processing module 11 may control the host vehicle to turn off the cabin part function, and to turn off the body part function. For example, the way of shutting off the cabin part function may be: and disconnecting power interfaces of the monitoring camera and the streaming media rearview mirror camera in the cabin.
The way of shutting off the body part function may be: the power supply interface of electronic devices such as the monitor for the hand drop, the steering wheel heater, the power socket assembly (front row), the power socket assembly (front luggage case), the mobile phone wireless charging, the power socket assembly (rear luggage case), the left instrument atmosphere lamp, the left middle control atmosphere lamp, the left front atmosphere lamp, the left rear atmosphere lamp, the right instrument atmosphere lamp, the right middle control atmosphere lamp, the right front atmosphere lamp, the right rear atmosphere lamp, the electric color-changing sky screen, the car door radar and the like is disconnected.
It should be noted that, in the fourth embodiment, the owner user can also select the electronic device to be turned off in the super power saving mode according to the requirement through the central control display screen or the operation interface of the mobile phone APP, so that flexible customization of the super power saving mode can be realized, and the user experience can be improved.
For example, in an operation interface of a central control display screen of the vehicle, all electronic devices that can be turned off in the super power saving mode may be displayed, and a vehicle owner may select, through the operation interface of the central control display screen, corresponding electronic devices that need to be turned off and do not need to be turned off in the super power saving mode, thereby completing private customization of the super power saving mode to serve as a preset control strategy suitable for the vehicle owner himself. After the configuration of the super power saving mode is finished, when the super power saving mode is started, corresponding electronic devices on the automobile can be controlled to operate according to the latest preset control strategy set by a user, so that the automobile can operate in the super power saving mode set by the user.
In a fifth embodiment, step 120 may comprise:
the intensity of the sliding energy recovery of the wheel drive motor is set to the maximum value for energy recovery.
Understandably, in the super power saving mode, the processing module 11 may adjust the coasting energy recovery intensity of the wheel driving motors to the maximum value CoastEnerCoverMax, so as to increase the recovered energy to the maximum extent.
In a sixth embodiment, step 120 may comprise:
the vehicle is controlled to travel at a travel speed equal to or less than a predetermined vehicle speed.
The maximum speed limit of the current electric automobile is generally between 160 and 180 km/h. After the super power-saving mode is started, the processing module 11 may set the highest vehicle speed VehVMax to 120km/h (i.e. an example of the designated vehicle speed, the designated vehicle speed may also be other vehicle speeds less than 120 km/h), so as to avoid that the vehicle runs at a high vehicle speed, thereby reducing the power consumption of the pure electric vehicle.
The implementation mode of limiting the vehicle speed can be realized by limiting the torque of the vehicle. For example, by the actual vehicle speed V, the actual driver demand torque T Drv Rolling resistance coefficient A Veh 、B Veh 、C Veh And the radius of the wheel R Whl Performing PI (Proportional Integral) control to obtain torque reduction torque T qDec ：
T qDec ＝a*T Drv +(b*A Veh +c*B Veh *V+d*C Veh *V 2 )*R Whl (2)
In the formula (2), T qDec The torque needing to be reduced is referred to as torque reduction torque; a. b, c and d are adjusting coefficients which are determined by actual vehicle calibration and part characteristics; a. The Veh 、B Veh 、C Veh Respectively refer to corresponding rolling resistance coefficients, and can be determined according to actual conditions; r Whl Refers to the wheel radius; v denotes the actual vehicle speed.
Will actually be needed by the driverTorque T is obtained Drv And torque reduction torque T qDec Obtaining the motor execution torque T by difference qIPU ：
T qIPU ＝T Drv -T qDec (3)
