Technical Field

[0001] This application relates to the field of intelligent driving technology, and in particular to a power consumption control method, device, equipment and medium for an intelligent driving system. Background Technology

[0002] Power consumption control in intelligent driving systems is a fundamental energy management technology within the vehicle's electronic and electrical architecture, involving the power consumption management of core computing units such as the intelligent driving domain controller and the onboard central computing platform. As intelligent driving functions evolve from driver assistance to advanced autonomous driving, the computing power required by the system increases exponentially, leading to a sharp rise in power consumption and heat dissipation demands. How to optimize vehicle energy consumption distribution and extend the driving range of electric vehicles while ensuring the real-time performance and reliability of intelligent driving functions has become a key issue in the design and engineering application of intelligent driving systems.

[0003] Currently, most intelligent driving systems operate in a fixed computing power mode (such as fixed computing power level and fixed power consumption configuration) when performing power consumption control, without taking into account the dynamic changes in the relative position relationship between the vehicle and the operating design domain and the driving trend during the driving process, resulting in invalid power consumption when the vehicle is outside the operating design domain.

[0026] The following is a brief explanation of the terms used in this application: Operational Design Domain (ODD): The specific range of conditions under which an intelligent driving system is designed to operate safely and effectively, including a set of constraints such as road type, speed range, and environmental conditions.

[0034] With the rapid development of intelligent driving technology and the continuous increase in the demand for vehicle energy consumption optimization, achieving precise matching between vehicle position and situation and the computing power supply strategy of the intelligent driving system has become an important technical direction for enhancing the timeliness of computing power response and optimizing the energy consumption distribution of the entire vehicle. Currently, the power consumption control of intelligent driving systems generally adopts the traditional technical architecture of fixed computing power level or preset power consumption configuration. The inventors have discovered that in actual driving, due to the influence of the relative position relationship between the vehicle and the operating design domain and the difference in driving direction (such as the vehicle approaching or moving away from the operating design domain boundary), the demand for computing power reserves and power consumption control of the intelligent driving system varies significantly. However, when dealing with these complex driving scenarios involving vehicle position perception, boundary situation assessment, and dynamic adjustment of computing power, existing solutions still use a uniform operating strategy with a fixed computing power mode, resulting in ineffective power consumption when the vehicle is outside the operating design domain.

[0035] To address the aforementioned technical problems, the inventive concept of this application is as follows: by acquiring the vehicle's current position and driving information, and determining the relative positional relationship and distance relationship between the vehicle and the operating design domain based on the boundary position of the operating design domain, and combining the driving direction to determine the vehicle's spatial positional situation and driving trend relative to the operating design domain, the computing power mode level of the intelligent driving system is adjusted in a differentiated manner. This achieves dynamic coordination and precise power consumption control between the vehicle's positional situation and computing power supply strategy, overcomes the defects of ineffective power consumption loss in the traditional fixed computing power mode, ensures real-time synchronization of positional situational perception and computing power adjustment control when the vehicle approaches or moves away from the operating design domain, and improves the adaptability of the intelligent driving system to power consumption and computing power requirements and the overall energy economy of the vehicle.

[0036] The technical solutions of this application and how they solve the aforementioned technical problems will be described in detail below with specific embodiments. These 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 this application will now be described with reference to the accompanying drawings.

[0037] It should be noted that the executor of this application may be a vehicle, and more specifically, a vehicle controller or vehicle processor, such as an intelligent driving domain controller, a vehicle controller, an on-board central computing platform, a parking and driving integrated controller, an intelligent driving system processor, etc.

[0038] refer to Figure 1 , Figure 1 A flowchart illustrating a power consumption control method for an intelligent driving system provided in an embodiment of this application. Figure 1 As shown, the power consumption control method of this intelligent driving system includes at least the following steps: S101: Obtain the vehicle's current location and driving information, and determine the relative position and distance relationship between the vehicle and the operation design domain based on the current location and the boundary position of the operation design domain.

[0039] The driving information includes the direction of travel.

[0040] Specifically, the vehicle's current location can be obtained through an onboard positioning module, and the boundary position of the operating design domain can be determined based on electronic map data or preset geofence information. Then, by calculating the spatial coordinate difference between the current location and the boundary position, the relative position of the vehicle with respect to the operating design domain (e.g., whether it is inside or outside the operating design domain) and the distance relationship (e.g., the straight-line distance or path distance to the boundary) can be determined. Furthermore, driving information can be obtained through onboard sensors (such as wheel speed sensors, steering wheel angle sensors, or inertial measurement units) to determine the vehicle's driving direction.

[0041] S103: If the relative positional relationship and distance relationship meet the first preset conditions, and the vehicle is driven towards the operating design domain based on the driving direction, then the computing power mode level of the intelligent driving system is increased.

[0042] Specifically, the first preset condition can be set as follows: the vehicle is outside the operating design domain and the distance between it and the boundary is less than or equal to a certain preset threshold (e.g., within a preset distance range outside the boundary). Combined with the driving direction, it is determined that the vehicle is driving towards the boundary of the operating design domain. At this time, the vehicle is about to enter the operating design domain. The intelligent driving system needs higher computing power to ensure the real-time performance and reliability of perception, decision-making and control functions. Therefore, the computing power mode level is increased from the current level to a higher level (e.g., switching from low power / low computing power mode to high power / high computing power mode), and the system power consumption is increased accordingly to ensure driving safety.

[0043] S105: If the relative position relationship and distance relationship meet the second preset condition, and the vehicle is determined to be moving away from the operating design domain based on the driving direction, then the computing power mode level of the intelligent driving system is reduced to reduce power consumption accordingly.

[0044] Specifically, the second preset condition can be set as follows: the vehicle is outside the operating design domain, has driven out of the boundary, and the distance between the vehicle and the boundary is greater than a certain preset threshold but less than or equal to another larger preset threshold (e.g., within a preset distance range outside the boundary). Combined with the driving direction, it is determined that the vehicle is moving away from the boundary of the operating design domain. At this time, the vehicle has driven out of the operating design domain for a certain distance, and the intelligent driving system does not need to maintain high computing power operation. Therefore, the computing power mode level is reduced from the current level to a lower level (e.g., switching from high power consumption / high computing power mode to low power consumption / low computing power mode), thereby reducing system power consumption and saving vehicle energy consumption. When the distance between the vehicle and the boundary exceeds the preset range, the reduction of the computing power mode level stops, and the current level is maintained for stable operation to avoid excessive reduction of computing power leading to abnormal system function.

[0045] Thus, this application monitors the relative position, distance, and direction of the vehicle and the operating design domain in real time. Before the vehicle enters the operating design domain, the computing power mode level is increased in advance to ensure real-time driving response and driving safety. After the vehicle leaves the operating design domain, the computing power mode level is reduced in a timely manner to reduce ineffective power consumption. After exceeding the preset distance range, the computing power level is kept stable to avoid excessive reduction of computing power, which could lead to abnormal basic functions of the intelligent driving system or driving safety risks. This achieves precise matching between computing power supply and the actual position and situation of the vehicle, and improves the adaptability of power consumption control of the intelligent driving system and the energy economy of the whole vehicle.

[0046] It should be noted that the computing power mode level / power consumption mode level of intelligent driving can include the lowest level, the highest level, and intermediate levels.

[0047] Minimum Level: At this level, the intelligent driving system only retains the minimum computing power cores related to safety monitoring and communication, while redundant processing chips are completely powered off. In the perception unit, only sensors directly related to driving safety are powered, and the power supply to the remaining computing cores and sensors is stopped. This can also be called human-driven mode, where the driver takes complete control of the vehicle.

[0048] Highest level: At this level, the redundant processing chip is powered on and all sensors in the perception unit are activated. For example, the highest level can be L3 scene mode to meet the full computing power requirements of L3 conditional autonomous driving for real-time processing of massive sensor data and complex path planning.

[0049] Intermediate level: Between the highest and lowest levels, at this level, the redundant processing chip is in a power-off or low-power standby state, and some sensors in the perception unit are in an active state. For example, the intermediate level can be an L2.9 scene mode to reduce system power consumption while meeting the requirements of L2 level assisted driving functions.

[0050] In some embodiments, the first preset condition includes: the relative positional relationship indicates that the vehicle is outside the operating design domain, and the distance relationship indicates that the vehicle is within a first preset range of the boundary position; The second preset condition includes: the relative positional relationship indicates that the vehicle is outside the operating design domain, and the distance relationship indicates that the vehicle is within the second preset range of the boundary position.

[0051] Specifically, the first preset range can be set as the near-distance area outside the boundary of the operating design domain. When a vehicle is within this range and moving towards the operating design domain, it indicates that the vehicle is about to enter the operating design domain, satisfying the first preset condition. The second preset range can be set as the medium-to-long-distance area outside the boundary of the operating design domain. When a vehicle is within this range and moving away from the operating design domain, it indicates that the vehicle has traveled a certain distance outside the operating design domain, satisfying the second preset condition. By dividing the space outside the boundary into different distance levels, differentiated computing power adjustment based on the distance between the vehicle and the boundary and the driving trend is achieved.

[0052] Understandably, the near-field region refers to a preset distance range extending outward from the boundary of the operational design domain (such as a ring-shaped or strip-shaped area within a radius of 50 or 100 meters outside the boundary). When a vehicle is within this region and moving towards the operational design domain, the system can predict that the vehicle is about to enter the operational design domain, thereby triggering an upgrade of the computing power mode level in advance. This allows for response time to accommodate the high computing power demands after entering the operational design domain, avoiding perception or decision-making delays caused by computing power switching lag when the vehicle first enters the boundary.

[0053] The medium-to-long-range region refers to the distance range extending beyond the boundary of the operational design domain, beyond the near-range region but still within the third preset threshold (e.g., a ring / strip-shaped area within 100 to 500 meters outside the boundary). When a vehicle is within this region and moving away from the operational design domain, the system can determine that the vehicle has traveled a certain distance outside the operational design domain, thereby triggering a reduction in the computing power mode level to reduce unnecessary power consumption. At the same time, the outer edge of this region is limited by the third preset threshold. When the distance between the vehicle and the boundary exceeds this threshold, the reduction in computing power stops to prevent the intelligent driving system's basic functions from malfunctioning due to the vehicle moving too far away from the operational design domain and causing a continuous decline in computing power.

[0054] In view of this, this embodiment divides the outer boundary into preset distance ranges of different levels and adjusts the computing power mode level differently based on the driving direction, thereby achieving fine-grained control of computing power supply before and after the vehicle enters the operating design domain. When the vehicle is in the close range outside the boundary and moving towards the operating design domain, the computing power mode level is increased in a timely manner to ensure real-time driving response; when the vehicle is in the medium to long range outside the boundary and moving away from the operating design domain, the computing power mode level is reduced in a timely manner to reduce ineffective power consumption. Thus, while ensuring timely computing power supply, it avoids continuous high-power operation after the vehicle moves away from the operating design domain, improving the accuracy of power consumption control of the intelligent driving system and the overall energy economy of the vehicle.

[0055] It should be noted that the first preset range and the second preset range can be different values ​​of the near distance area and the medium-to-far distance area mentioned above, or they can be the same value (such as both being near distance areas).

[0056] In some embodiments, determining the distance relationship between the vehicle and the operational design domain based on the current location and the boundary location of the operational design domain includes: Obtain the vehicle's current navigation route; Based on the current navigation path, calculate the current distance between the vehicle's current position and the boundary position of the operating design domain; If the current distance is less than or equal to the first distance threshold, then the vehicle is determined to be within the first preset range of the boundary position; If the current distance is greater than the second distance threshold and less than the preset distance threshold, then the vehicle is determined to be within the second preset range of the boundary position.

[0057] Specifically, the current navigation path can be obtained through the in-vehicle navigation module or a high-precision map, reflecting the actual route the vehicle plans to take. Based on this navigation path, the path distance between the vehicle's current position and the boundary of the operational design domain (i.e., the distance traveled along the navigation path from the current position to the boundary) is calculated. A first distance threshold corresponds to the near-distance range outside the boundary; when the current distance is less than or equal to this threshold, it indicates that the vehicle is about to reach the boundary along the planned path. A second distance threshold and a preset distance threshold together define the medium-to-long-distance range outside the boundary; when the current distance is greater than the second distance threshold but less than the preset distance threshold, it indicates that the vehicle has traveled a certain distance beyond the boundary along the planned path but is still within the effective range of computing power adjustment. Thus, the distance calculation is based on the actual navigation path rather than a straight-line distance in space, which is closer to the vehicle's actual driving trajectory. It should be noted that the first distance threshold can be different from or the same as the second distance threshold, but the second distance threshold must be less than the preset distance threshold.

[0058] Therefore, this embodiment calculates the path distance between the vehicle and the boundary of the operation design domain based on the current navigation path, making the determination of the distance relationship more consistent with the actual driving trajectory of the vehicle. This avoids the deviation caused by straight-line distance determination in scenarios such as road detours and obstacle avoidance, and improves the accuracy of the positional relationship determination between the vehicle and the boundary of the operation design domain. As a result, the timing of switching computing power mode levels is more precise. While ensuring the timely supply of computing power before the vehicle enters the operation design domain, it also reduces the ineffective power consumption after the vehicle moves away from the operation design domain.

[0059] In some embodiments, determining the distance relationship between the vehicle and the operational design domain based on the current location and the boundary location of the operational design domain includes: Obtain the vehicle's current navigation route; Based on the current navigation path, calculate the current distance between the vehicle's current position and the boundary position of the operating design domain; Calculate the reference time based on the current distance and current vehicle speed; If the reference time is less than or equal to the first time threshold, the vehicle is determined to be within the first preset range of the boundary position; If the reference time is greater than the second time threshold but less than the preset time threshold, then the vehicle is determined to be within the second preset range of the boundary position.

[0060] Specifically, the current vehicle speed can be obtained through onboard wheel speed sensors or the onboard CAN bus. The reference time is calculated by dividing the current path distance by the current vehicle speed, representing the reference time required for the vehicle to reach or leave the boundary of the operational design domain along the navigation path at the current speed. The first time threshold corresponds to the computing power switching response time that needs to be reserved before the vehicle enters the operational design domain. When the reference time is less than or equal to this threshold, it indicates that the vehicle is about to reach the boundary at the current speed, satisfying the first preset condition. The second time threshold and the preset time threshold together define the effective time interval after the vehicle leaves the operational design domain. When the reference time is greater than the second time threshold but less than the preset time threshold, it indicates that the vehicle has left the boundary for a reasonable period of time at the current speed and is still within the effective range of computing power adjustment, satisfying the second preset condition. Adjustment stops when the preset time threshold is exceeded. Thus, the determination of distance relationships is transformed from a static spatial dimension to a dynamic time dimension, which better reflects the actual driving rhythm of the vehicle. Similarly, the first time threshold can be different from or the same as the second time threshold, but the second time threshold must be less than the preset time threshold.

[0061] Therefore, this embodiment transforms the path distance between the vehicle and the boundary of the operational design domain into a reference time based on the current vehicle speed. A time threshold replaces the fixed distance threshold for preset range determination, dynamically linking the timing of computing power mode level switching to the vehicle's actual speed. When the vehicle is moving towards the operational design domain at a high speed, even with a long path distance, a shorter reference time can trigger a computing power boost earlier, avoiding lag in computing power switching at high speeds. When the vehicle is moving away from the operational design domain at a low speed, even if the path distance has entered the second preset range, a longer reference time can delay the reduction in computing power, preventing premature load reduction in low-speed scenarios from affecting the system's basic functions. This improves the timeliness of computing power boosting when the vehicle approaches the operational design domain and the accuracy of computing power reduction when moving away from the operational design domain, ensuring real-time driving response while reducing unnecessary power consumption.

[0062] In some embodiments, the increase or decrease of the computing power mode level can be adjusted gradually. For example, when the vehicle moves towards the operating design domain and the reference time gradually increases from a large to a small value, crossing a first time threshold, the computing power mode level gradually increases from the current level through intermediate levels to the highest level; when the vehicle moves away from the operating design domain and the reference time gradually increases from a small to a large value, exceeding a second time threshold, the computing power mode level gradually decreases from the current level through intermediate levels. Each level corresponds to a different power supply state combination of the redundant processing chip and the sensing unit sensor. This avoids sudden changes in system load caused by instantaneous jumps in the computing power mode level, improving the stability of the intelligent driving system.

[0063] In some embodiments, the intelligent driving system includes a computing unit and a sensing unit. The computing unit includes a main processing chip and at least one redundant processing chip, and the sensing unit includes at least two sensors. Improve the computing power mode level of the intelligent driving system, including at least one of the following: Power the redundant processing chip; Power is supplied to all sensors in the sensing unit.

[0064] Specifically, the redundant processing chip can be in a power-off or low-power standby state under normal operating conditions. When it is necessary to increase the computing power mode level, the power management unit supplies power to the redundant processing chip, switching it from standby state to working state, and cooperating with the main processing chip. When some sensors in the sensing unit are in a low-power or sleep state, the sensor power management module supplies power to all sensors, enabling them to synchronously collect environmental data, increasing the dimensions and amount of sensing information input.

[0065] Therefore, this embodiment improves the computing power supply of the intelligent driving system by enhancing the computing power mode level from at least one dimension, namely, the collaborative wake-up of redundant processing chips and the full sensor activation of the perception unit. As the vehicle approaches the operational design domain, not only is the processing performance of the core computing unit improved, but the participation of redundant chips also expands parallel computing resources. Simultaneously, the synchronous activation of all sensors increases the data input dimension for environmental perception, ensuring that the computing power enhancement covers the entire computing and perception chain, guaranteeing a sufficient supply of perception and computing capabilities for the intelligent driving system when entering the operational design domain.

[0066] In some embodiments, reducing the computing power mode level of the intelligent driving system includes at least one of the following: Stop supplying power to the redundant processing chip; Stop supplying power to some sensors in the sensing unit.

[0067] Specifically, the redundant processing chip is in working state when the computing power mode level is increased. When it is necessary to reduce the computing power mode level, the power management unit stops supplying power to the redundant processing chip, switching it from working state to power-off or low-power standby state, and stopping its collaborative operation with the main processing chip. Some sensors in the sensing unit are in fully activated state when the computing power mode level is increased. When it is necessary to reduce the computing power mode level, the sensor power management module stops supplying power to some of these sensors (such as two forward millimeter-wave radars, two front-angle radars, and three blind-spot lidars), switching them from working state to power-off or sleep state, reducing the dimensions and amount of sensing information input, while the remaining sensors remain working to maintain basic sensing capabilities.

[0068] Therefore, this embodiment achieves flexible reduction of computing power supply in the intelligent driving system by reducing the computing power mode level from at least one dimension, such as power-off standby of redundant processing chips and deactivation of some sensors in the sensing unit. When the vehicle is far from the operating design domain, the power consumption can be reduced accordingly at the computing unit or sensing unit level through adjustments in at least one of the above dimensions. This allows the reduction in computing power to adapt to actual operating needs, precisely reducing the overall power consumption of the system when it is far from the operating design domain while ensuring the normal operation of the basic functions of the intelligent driving system.

[0069] In some embodiments, during the vehicle power-on and startup phase, the intelligent driving system performs an initialization self-test. The main processing chip, redundant processing chip, and all sensors in the sensing unit are powered on and operational, and the computing power mode level is initialized to the highest level. This ensures that the system has full perception and computing capabilities during vehicle startup and initial operation, preventing environmental perception or safety monitoring functions from failing due to insufficient initial computing power.

[0070] In some embodiments, the method further includes: If the relative positional relationship indicates that the vehicle is within the operational design domain, then the computing power mode level of the intelligent driving system should be maintained at the highest level.

[0071] Specifically, the operational design domain is the specific range of conditions (such as road type, speed range, environmental conditions, etc.) under which the intelligent driving system is designed to operate normally. When the vehicle is within the operational design domain, it indicates that the current driving environment is within the system's effective operating range. The intelligent driving system needs to maintain full computing power to ensure the real-time performance and reliability of environmental perception, path decision-making, and motion control functions. At this time, the computing power mode level of the intelligent driving system is maintained at the highest level, that is, the redundant processing chip is kept powered on and all sensors in the perception unit are kept active, ensuring that the system's computing power and perception resources are fully utilized.

[0072] Based on this, this embodiment ensures that the intelligent driving system maintains full computing power supply and perception capability within its effective working range by keeping the computing power mode level at the highest level when the vehicle is within the operating design domain. This avoids environmental perception delays, path decision lags, or insufficient control response caused by computing power mode fluctuations or erroneous load reduction, thus ensuring the real-time performance, continuity, and reliability of intelligent driving functions within the operating design domain.
