[0055] The electric vehicle sleep control method, vehicle controller, vehicle and medium of the present application can be used in the field of vehicle control technology, and can also be used in any field other than the field of vehicle control technology, such as the field of vehicle sleep technology, etc. The application field of the electric vehicle sleep control method, vehicle controller, vehicle and medium of the present application is not limited.

[0056] The electric vehicle sleep control method, vehicle controller, vehicle and medium of the present application can be applied to scenarios where electric vehicles are subjected to sleep control. The electric vehicles can be electric commercial vehicles or electric passenger vehicles. Any scenario involving sleep control of electric vehicles can apply the electric vehicle sleep control method, vehicle controller, vehicle and medium of the present application.

[0057] In recent years, electric vehicles have made great progress, but due to the limitations of energy replenishment methods, energy consumption restricts the development of electric vehicles, especially electric commercial vehicles.

[0058] In related technologies, after electric commercial vehicles are powered on, they are typically controlled through switches and logic thresholds, with each component typically independently controlled by a controller. For example, the motor's power consumption is controlled by a motor controller. Once the motor controller detects that the motor signal is less than the corresponding logic threshold, it controls the motor to a standby state. Throughout the entire operating process, various power-consuming components are often in standby mode, such as high-voltage standby, low-voltage standby, and the thermal management system remains inactive for extended periods of time. This results in significant energy waste and high vehicle energy consumption.

[0059] Based on the above technical problems, the inventive concept of this application is: how to provide an electric vehicle sleep control solution that can reduce vehicle energy consumption.

[0060] The embodiments of the present application provide an electric vehicle sleep control method, a vehicle controller, a vehicle and a medium, which can divide the high-voltage and low-voltage power-consuming components of the electric vehicle into multiple partitioned sleep systems for modular energy consumption management, and dynamically adjust the power supply status of each area according to real-time needs. When the partitioned sleep system is in standby mode, the partitioned sleep system is controlled to sleep according to the sleep time threshold of the partitioned sleep system in the current vehicle mode. Without affecting functional safety and satisfying customer function trials, the system sleep in the vehicle is timely controlled to reduce the energy consumption of the electric vehicle.

[0061] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0062] Figure 1 This is a system architecture diagram of an embodiment of the present application, such as Figure 1 As shown, an electric vehicle includes a vehicle controller and a partitioned sleep system. The partitioned sleep system includes a driving power system, a thermal management system, a powertrain system, and an onboard electronic system. The vehicle controller is in communication with the driving power system, the thermal management system, the powertrain system, and the onboard electronic system. The vehicle controller can obtain vehicle status information; determine the current vehicle mode based on the vehicle status information; determine the sleep time threshold for the vehicle's partitioned sleep system in vehicle mode; determine whether the partitioned sleep system is in a standby state based on the vehicle status information; and when the partitioned sleep system is in the standby state, control the sleep time threshold for the partitioned sleep system.

[0063] Figure 2 This is a flow chart of an electric vehicle sleep control method according to an embodiment of the present application. This embodiment describes the electric vehicle sleep control method with the vehicle controller as the execution subject. Figure 2 As shown, the electric vehicle sleep control method may include the following steps:

[0064] S201: Acquire vehicle status information of the vehicle, and determine the current vehicle mode according to the vehicle status information.

[0065] In this embodiment, the electric vehicle may be an electric commercial vehicle such as an electric mixer truck, an electric tractor truck, an electric crane, or an electric sanitation vehicle.

[0066] In this embodiment, the vehicle controller may obtain the vehicle status information through the CAN bus, or may obtain the vehicle status information through other means, without any limitation herein.

[0067] In this embodiment, the vehicle status information may include operation signals input by the user through an operation panel or an operating handle, button, etc., vehicle body information such as vehicle speed and acceleration, upper load status, gear information, temperature of various vehicle components, etc. The vehicle status information can be flexibly set by those skilled in the art according to actual conditions, and no restrictions are made here. As long as the information can characterize the status of the electric vehicle, it can be used as vehicle status information.

[0068] In this embodiment, the vehicle mode may include a driving mode, an operating mode, a parking mode, etc. Those skilled in the art may flexibly set the vehicle mode according to actual conditions.

[0069] For example, taking an electric mixer truck as an example, when the speed of the electric mixer truck is greater than 0, the electric mixer truck is in driving mode; when the speed of the electric mixer truck is 0 and the parking signal is on, the electric mixer truck is in parking mode; when the speed of the electric mixer truck is 0 and the load weight of the electric mixer truck changes (empty→full load or full load→empty), the electric mixer truck is in operating state.

[0070] S202: Determine a sleep time threshold of a partitioned sleep system of the vehicle in a vehicle mode.

[0071] In this embodiment, the high-voltage and low-voltage power-consuming components of an electric vehicle can be pre-divided into multiple partitioned dormant systems, such as the high-voltage driving power system, thermal management system, and upper vehicle power system, and the low-voltage onboard electronic system. Those skilled in the art can flexibly configure the partitioned dormant systems based on actual needs, and no limitation is imposed herein.

[0072] In this embodiment, different partitioned sleep systems may correspond to different sleep time thresholds in the same vehicle mode, and the same partitioned sleep system may also correspond to different sleep time thresholds in different vehicle modes.

[0073] S203: Determine whether the partitioned dormancy system is in a standby state according to the vehicle state information.

[0074] In this embodiment, for a partitioned sleep system, it can be determined based on vehicle status information whether all components / modules in the partitioned sleep system are in standby state. If all components / modules are in standby state, it can be considered that the partitioned sleep system is in standby state.

[0075] S204: When the partitioned sleep system is in the standby state, the partitioned sleep system is controlled to sleep according to the sleep time threshold.

[0076] In this embodiment, when it is determined that a partitioned sleep system is in standby state, the vehicle controller can obtain the duration that each component / module of the partitioned sleep system is in standby state. If the duration exceeds the sleep time threshold corresponding to the partitioned sleep system, the partitioned sleep system can be controlled to power off and sleep.

[0077] In this embodiment, the various electrical components of the vehicle can be divided into multiple partitioned sleep systems according to their functions, and modular energy consumption management can be performed using the vehicle controller. After determining the current vehicle mode based on the vehicle status information, the sleep time threshold of each partitioned sleep system in the vehicle mode can be determined. When a partitioned sleep system is in standby mode, the vehicle controller can control the sleep mode of the partitioned sleep system based on the sleep time threshold of the partitioned sleep system in the vehicle mode, thereby achieving timely control of system sleep in the vehicle and reducing energy consumption of electric vehicles without affecting the functional safety of the vehicle and satisfying customer functional trials.

[0078] In one possible implementation, the vehicle status information may include one or more of the following:

[0079] User operation instructions, vehicle speed, upper load information, gear information, temperature information of vehicle components, vehicle body information, ambient temperature, and remaining battery power.

[0080] In this embodiment, the vehicle status information is not limited to the above information. Those skilled in the art can flexibly set it according to actual conditions. No limitation is made here. As long as the information can represent the status of the electric vehicle, it can be used as vehicle status information.

[0081] In this embodiment, the vehicle mode and the status of the driving power system can be determined based on user operation instructions, vehicle speed, gear information, vehicle body information, etc. The status of the upper power system can be determined based on user operation instructions, upper load information, etc. The status of the thermal management system can be determined based on user operation instructions, temperature information of various vehicle components, ambient temperature, etc. The status of the on-board electronic system can be determined based on user operation instructions, remaining battery power, etc.

[0082] In one possible implementation, the partitioned dormancy system may include one or more of a driving power system, an onboard electronic system, a thermal management system, and a superstructure power system.

[0083] In this embodiment, the driving power system, the thermal management system, and the upper body power system may be high-voltage systems, and the onboard electronic system may be a low-voltage system.

[0084] The driving power system (high-voltage area) may include: a drive motor, a steering motor, an air pump motor, and an electronic control unit.

[0085] The thermal management system (high-voltage area) can include: battery temperature control, air conditioning compressor, and PTC.

[0086] The on-board electronic system (low-voltage area) may include: instrument panel, sensors, and communication modules.

[0087] The upper power system (high-pressure area) may include: a stirring tank drive motor and an operating handle.

[0088] In this embodiment, the partitioned hibernation system is not limited to the above content, and those skilled in the art can flexibly configure it according to actual conditions, and no limitation is imposed here.

[0089] For example, vehicles with upper loads, such as electric mixer trucks and electric cranes, may include a driving power system, an on-board electronic system, a thermal management system, and an upper power system; vehicles without upper loads, such as electric sanitation vehicles, may include a driving power system, an on-board electronic system, and a thermal management system.

[0090] In this embodiment, the vehicle can be divided into a high-voltage driving power system, a thermal management system, a body power system, and a low-voltage on-board electronic system, so that the vehicle controller can be used to perform modular energy consumption management on each system.

[0091] In one possible implementation, the above step S202 of determining the sleep time threshold of the partitioned sleep system of the vehicle in the vehicle mode may include:

[0092] S11: For each partitioned dormant system, determine the activation weight of the partitioned dormant system in the vehicle mode according to a preset correspondence between the partitioned dormant system and the activation weight.

[0093] S12: Determine the basic standby time of the partitioned sleep system in the vehicle mode according to a preset correspondence between the partitioned sleep system and the basic standby time.

[0094] S13: Determine a sleep time threshold of the partitioned sleep system in the vehicle mode according to the activation weight and the basic standby time.

[0095] In this embodiment, those skilled in the art may pre-set a corresponding basic standby time for each partitioned sleep system. The basic standby times of different partitioned sleep systems may be the same or different, and no limitation is imposed herein.

[0096] In this embodiment, those skilled in the art may also pre-set the activation weights of each partitioned dormant system in different vehicle modes based on actual conditions. For example, the activation weight of the driving power system is the highest in driving mode, and the activation weight of the upper body power system is the highest in working mode.

[0097] In this embodiment, different partitioned dormancy systems may correspond to different activation weights in the same vehicle mode, and the same partitioned dormancy system may also correspond to different activation weights in different vehicle modes.

[0098] In this embodiment, after the activation weight T and the basic standby time A are determined, the sleep time threshold can be obtained according to T×A.

[0099] For example, the following table 1 is a table showing the correspondence between the dormant systems of each partition and the activation weights, as shown in Table 1:

[0100] Driving power system In-vehicle electronic systems Thermal Management System Upper power system Driving Mode 0.9 0.5 0.4 0.8 Parking mode 0.2 0.7 0.2 0.3 Operation Mode 0.1 0.4 0.3 0.9

[0101] For example, taking an electric mixer truck as an example, the vehicle controller detects that the electric mixer truck is currently in operation mode, and the basic standby time of the upper power system is 5 minutes. It can be seen from Table 1 that the activation weight of the upper power system is 0.9, and the sleep time threshold of the upper power system is 0.9×5min=4.5min.

[0102] In this embodiment, after determining the vehicle mode, the activation weight of the partitioned sleep system in the vehicle mode can be accurately determined based on the pre-set correspondence between the partitioned sleep system and the activation weight, and the sleep time threshold of the partitioned sleep system in the vehicle mode can be accurately determined based on the basic standby time of the partitioned sleep system in the vehicle mode and the activation weight.

[0103] In one possible implementation, the above step S203 of determining whether the partitioned dormancy system is in a standby state according to the vehicle state information may include:

[0104] S21: For each partitioned dormant system, determine system status information corresponding to the partitioned dormant system according to vehicle status information.

[0105] S22: Determine whether all components and / or functional modules in the partitioned hibernation system are in a standby state based on the system status information; or, determine whether all components and / or functional modules in the partitioned hibernation system except for the preset required running parts are in a standby state based on the system status information.

[0106] S23: If both are in the standby state, it is determined that the partitioned hibernation system is in the standby state.

[0107] S24: If not all of them are in the standby state, it is determined that the partitioned hibernation system is not in the standby state.

[0108] In this embodiment, the preset required operating parts may be components essential for the functioning of the electric vehicle. For example, when an electric mixer is in standby mode, the mixing drum must remain in operation to prevent material solidification. Those skilled in the art may flexibly set the preset required operating parts based on the specific vehicle type and partitioned sleep system, and no limitation is imposed herein.

[0109] In this embodiment, it is possible to accurately determine whether the partitioned hibernation system is in standby state based on whether all components and / or functional modules in the partitioned hibernation system are in standby state, or whether all components and / or functional modules other than the preset must-run parts are in standby state.

[0110] In one possible implementation, when the partitioned sleep system is a driving power system / vehicle electronic system, the sleep control of the partitioned sleep system according to the sleep time threshold in step S204 may include:

[0111] S31: Determine a first standby duration of the partitioned sleep system, where the first standby duration is a continuous standby duration of a component or module that last enters a standby state in the partitioned sleep system.

[0112] S32: Determine whether the first standby time exceeds the sleep time threshold corresponding to the partitioned sleep system.

[0113] S33: If it exceeds, the partition sleep system is controlled to power off and sleep.

[0114] S34: If it is not exceeded, the partition hibernation system is controlled to maintain the current state.

[0115] In this embodiment, the first standby time period may be the duration during which all components / modules of the partitioned hibernation system enter the standby state.

[0116] For example, the partitioned hibernation system includes components A, B and C. Component A enters standby mode at 10:00, component B enters standby mode at 10:05, and component C enters standby mode at 10:08. After component C (the last component to enter standby mode) enters standby mode, all components of the partitioned hibernation system are in standby mode. At this time, it can be confirmed that the partitioned hibernation system is in standby mode. The first standby period of the partitioned hibernation system starts from 10:08, the time when component C enters standby mode, until a component of the partitioned hibernation system is activated.

[0117] In this embodiment, based on the comparison between the first standby time length when the partitioned sleep system as a whole enters the standby state and the sleep time threshold, it can be simply and accurately determined whether to control the partitioned sleep system to be powered off and put into sleep. If the first standby time length exceeds the sleep time threshold, it can be considered that the partitioned sleep system is performing unnecessary operations, and the partitioned sleep system can be controlled to be powered off and put into sleep to reduce energy consumption.

[0118] In a possible implementation, the step S204 of controlling the sleep of the partitioned sleep system according to the sleep time threshold may include one or more of the following:

[0119] A: When the partitioned sleep system is a thermal management system, determine the second standby duration of the partitioned sleep system, where the second standby duration is the continuous standby duration of the last component or module to enter the standby state in the partitioned sleep system; determine the temperature change rate of each component in the partitioned sleep system; and determine whether the partitioned sleep system meets the following conditions: the second standby duration exceeds the sleep time threshold corresponding to the partitioned sleep system, and the temperature change rate of each component is less than the temperature change rate threshold; if so, control the partitioned sleep system to power off and enter sleep; if not, control the partitioned sleep system to maintain the current state.

[0120] B: When the partitioned sleep system is a superstructure power system, determine the third standby time of the partitioned sleep system, where the third standby time is the continuous standby time of the last component or module in the partitioned sleep system to enter the standby state; determine the load state of the partitioned sleep system; and judge whether the partitioned sleep system meets the following conditions: the third standby time exceeds the sleep time threshold corresponding to the partitioned sleep system, and the load state is no-load; if so, control the partitioned sleep system to power off and enter sleep mode; if not, control the partitioned sleep system to maintain the current state.

[0121] In this embodiment, the calculation of the second standby time and the third standby time is the same as the first standby time, which will not be repeated here. Both are calculated from the time when the last component in the partitioned hibernation system enters the standby state.

[0122] In this embodiment, those skilled in the art can flexibly set the temperature change rate threshold according to actual conditions. For example, the temperature change rate threshold can be 0.5°C / min or 1°C / min, and no limitation is made here.

[0123] In this embodiment, the load state of no load may be that the electric mixer truck is not loaded with materials, or the electric crane is not lifting materials, etc.

[0124] In this embodiment, when the partitioned hibernation system is a thermal management system, if the thermal management system is not in standby mode, the operating power of temperature control components such as the compressor can be adjusted according to the temperature change rate of each component to minimize energy consumption.

[0125] In this embodiment, when the partitioned sleep system is a thermal management system, if the duration of the thermal management system entering the standby state exceeds the corresponding sleep time threshold, and the temperature change rate of each component is less than the temperature change rate threshold, the thermal management system can be controlled to power off and sleep; when the partitioned sleep system is the upper power system, if the duration of the upper power system entering the standby state exceeds the corresponding sleep time threshold, and the load state is no-load, the partitioned sleep system can be controlled to power off and sleep.

[0126] The electric vehicle sleep control method of the present application is described below with reference to a specific embodiment.

[0127] In a specific embodiment, an operator operates an electric mixer truck to perform work. The vehicle controller performs sleep control on the electric mixer truck after the vehicle is powered on. The specific process is as follows:

[0128] In the first step, after the electric mixer truck is powered on, the vehicle controller obtains vehicle status information such as user operation instructions, vehicle speed, upper load information, gear information, temperature information of various vehicle components, body information, ambient temperature, and remaining battery power.

[0129] In the second step, the vehicle controller determines that the current vehicle mode of the electric mixer truck is the driving mode according to the vehicle status information.

[0130] In the third step, the vehicle controller determines that the activation weights of the driving power system, thermal management system, upper power system and on-board electronic system in the driving mode are 0.9, 0.5, 0.4 and 0.8 respectively, and the basic standby time of the driving power system, thermal management system, upper power system and on-board electronic system is 5 minutes. Then the sleep time thresholds of the driving power system, thermal management system, upper power system and on-board electronic system are 4.5 minutes, 2.5 minutes, 2 minutes and 4 minutes respectively.
