[0027] Example 1

[0028] Figure 1 This is a flowchart of a method for determining energy recovery during steering wheel turn, provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where vehicle steering energy is acquired during vehicle steering. This method can be executed by a device for determining energy recovery during steering wheel turn. This device can be implemented in hardware and / or software and can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0029] S110. Obtain vehicle driving information and steering wheel information.

[0030] Vehicle driving information can be information related to vehicle driving collected during vehicle operation, including but not limited to vehicle speed, vehicle travel angle, vehicle lane angle, distance to the vehicle in front, and remaining fuel. Steering information can be information describing the steering process during vehicle operation, including but not limited to steering torque, steering wheel hand reach, steering force, steering angle, steering frequency, steering speed, and steering wheel model.

[0031] Among them, vehicle speed can be used to describe the speed of the vehicle during the driving process; vehicle angle can be used to describe the angle between the vehicle's driving direction and the road extension direction; vehicle lane angle can be used to describe the angle of the road extension that the vehicle is traveling on; distance to the vehicle in front can be used to describe the distance between the vehicle and the vehicle in front, or to the person or obstacle, etc.; and remaining fuel can be used to describe the amount of fuel remaining in the vehicle's fuel tank at the current moment.

[0032] In addition, steering wheel torque can be used to describe the torque applied to the steering wheel during steering; steering wheel hand distance can be used to describe the distance from the driver's grip on the steering wheel to the center of the steering wheel in the vehicle; steering wheel force can be used to describe the magnitude of the force applied to the steering wheel to make it rotate; steering wheel angle can be used to describe the angle of steering wheel rotation; steering wheel speed can be used to describe the angle of steering wheel rotation per unit time; steering wheel frequency can be used to describe the number of times the steering wheel rotates per unit time; and steering wheel model can be used to describe the specific model information of the steering wheel.

[0033] During vehicle operation, the vehicle's driving process can be detected through bus and / or sensors to determine the vehicle's driving information and steering wheel information.

[0034] Optionally, the vehicle driving information includes at least the vehicle speed, vehicle driving angle, vehicle lane angle, and distance to the vehicle in front, and the steering information includes the steering torque, steering wheel hand distance, steering force, steering angle, steering frequency, and steering speed.

[0035] S120. Determine whether the conditions for starting energy recovery are met based on vehicle driving information and steering wheel information.

[0036] If all steering processes are deemed to meet the conditions for energy recovery activation during vehicle operation, it will inevitably affect the driver's driving experience and may even affect the driver's safety.

[0037] Therefore, it is necessary to use vehicle driving information and steering wheel information to determine whether energy can be recovered from the current driving situation of the vehicle without affecting the driver's driving experience and driving safety.

[0038] By determining whether the conditions for energy recovery are met based on vehicle driving information and steering wheel information, a judgment is made on whether energy recovery should be carried out before it is performed, so that the driver's driving experience and driving safety are not affected when energy recovery is carried out.

[0039] In one alternative approach, determining whether the energy recovery activation conditions are met based on vehicle driving information and steering wheel information may include steps A1-A3:

[0040] Step A1: Determine the time of vehicle collision based on the distance to the vehicle in front and the vehicle's speed.

[0041] Step A2: Determine the vehicle steering torque based on the vehicle collision time, vehicle travel angle, and vehicle lane angle.

[0042] Step A3: If the vehicle collision time is greater than the preset time and the steering wheel torque is greater than the vehicle steering torque, then the first energy recovery activation condition is met.

[0043] During vehicle operation, there may be situations such as following vehicles or pedestrians or obstacles in front of the vehicle. Therefore, the distance of vehicles, pedestrians or obstacles in front of the vehicle can be detected by radar, cameras or sensors installed in the vehicle, so as to obtain the distance to the vehicle in front.

[0044] After obtaining the distance to the vehicle in front, the vehicle's speed can be used to calculate and determine the collision time between the vehicle and the vehicle in front, or the pedestrian or obstacle.

[0045] Once the time of vehicle collision is determined, the vehicle steering torque can be determined using the time of collision, the vehicle's driving angle, and the vehicle's lane angle. This allows us to know the steering torque required for the driver to turn the steering wheel during the time of the collision.

[0046] After obtaining the vehicle collision time, it can be compared with the preset time. If the vehicle collision time is greater than the preset time, it means that the driver could have avoided the collision by changing lanes or other normal driving methods within the vehicle collision time.

[0047] The preset time can be determined based on past collision experience, representing the vehicle collision time under non-collision conditions corresponding to different distances from the vehicle in front and vehicle speeds.

[0048] If the vehicle collision time is less than the preset time, it means that the driver cannot avoid the collision by changing lanes or other normal driving methods within the vehicle collision time. Therefore, it can be determined that the driver needs to turn the steering wheel at a relatively fast speed within the vehicle collision time, and the torque that can reasonably avoid the collision at this time is the vehicle steering torque.

[0049] When the steering torque applied by the driver to the steering wheel is greater than the vehicle's steering torque, it indicates that the torque input by the driver exceeds the torque required to reasonably avoid a collision. At this time, the portion of the torque exceeding the reasonable torque is a recoverable torque.

[0050] Therefore, when the vehicle collision time is greater than the preset time and the steering wheel torque is greater than the vehicle steering torque, it can be determined that the first energy recovery activation condition is met.

[0051] At this point, the portion of the steering wheel torque that exceeds the vehicle's steering torque will be retracted.

[0052] The first energy recovery activation condition can be a judgment condition for recovering the portion of the steering wheel torque that is greater than the vehicle steering torque.

[0053] In one alternative approach, before determining that the first energy recovery activation condition is met if the vehicle collision time is greater than a preset time and the steering wheel torque is greater than the vehicle steering torque, steps B1-B3 are further included:

[0054] Step B1: Obtain the steering wheel hand-hold distance.

[0055] Step B2: Determine the steering force using the vehicle's onboard system.

[0056] Step B3: Determine the steering wheel torque based on the steering wheel hand-holding distance and steering wheel steering force.

[0057] After determining the vehicle's steering torque, it is necessary to determine the steering wheel torque input by the driver. This requires determining the distance the driver holds the steering wheel using the vehicle's in-vehicle camera or sensors.

[0058] When the driver applies steering force to the steering wheel, the vehicle system determines the magnitude of the steering force and uses the obtained steering wheel hand distance and steering force to determine the steering torque.

[0059] In one alternative approach, determining whether the energy recovery activation conditions are met based on vehicle driving information and steering wheel information further includes steps C1-C2:

[0060] Step C1: Obtain the vehicle's steering wheel frequency.

[0061] Step C2: If the steering wheel turning frequency is greater than the preset frequency, then the second energy recovery activation condition is met.

[0062] In addition to recovering torque exceeding the vehicle's steering torque as mentioned above, there is also lateral kinetic energy generated by vibrations from driving on bumpy roads, which is transmitted through the wheels to the steering linkage. Therefore, it is necessary to determine when the vehicle is driving on bumpy roads.

[0063] Therefore, it is necessary to obtain the steering wheel frequency of the vehicle in order to judge the driving road surface.

[0064] To address this, tests can be conducted on different vehicle models to determine their preset frequencies. These preset frequencies can be the minimum steering wheel frequency required for the vehicle on various bumpy road surfaces.

[0065] The steering wheel frequency is compared with the preset frequency. If the steering wheel frequency is greater than the preset frequency, it is determined that the vehicle is driving on a bumpy road, and the second energy recovery activation condition is met.

[0066] Among them, the second energy recovery activation condition can be a condition for determining whether to acquire lateral kinetic energy transferred to the steering gear tie rod.

[0067] In one alternative approach, determining whether the energy recovery activation conditions are met based on vehicle driving information and steering wheel information further includes steps D1-D3:

[0068] Step D1: Determine the status of the vehicle's automatic parking function.

[0069] Step D2: If the vehicle's automatic parking function is enabled, then obtain the vehicle's steering wheel speed.

[0070] Step D3: If the steering wheel speed is greater than the preset speed, then the third energy recovery start condition is met.

[0071] In addition to the two situations mentioned above, some steering energy can also be recovered when a vehicle is automatically parking.

[0072] To address this, the status of the vehicle's automatic parking function can be obtained through the vehicle's bus or onboard computer, thereby determining whether the automatic parking function is activated.

[0073] The automatic parking function status can be used to indicate whether the vehicle's automatic parking function is currently on or off.

[0074] If the automatic parking function is determined to be activated by checking its status, the steering wheel speed can be measured to determine if there is an excessive steering wheel speed.

[0075] Similar to the method for obtaining the preset frequency, different vehicle models can be tested to determine the preset speed for each model.

[0076] The preset speed can be the minimum steering wheel speed without affecting parking efficiency.

[0077] The steering wheel speed is compared with the preset speed. If the steering wheel speed is greater than the preset speed, it means that the heat energy generated by friction and the rapid rotation of the motor during the automatic parking process can be recovered without affecting the vehicle's automatic parking efficiency. At this time, it can be determined that the third energy recovery start condition is met.

[0078] Among them, the third energy recovery start-up condition can be the judgment condition for determining whether to obtain the heat energy generated by friction and the rapid rotation of the motor.

[0079] In one alternative approach, determining whether the energy recovery activation conditions are met based on vehicle driving information and steering wheel steering information also includes:

[0080] If the steering wheel angle is not at zero and the steering trend is approaching zero, and the steering torque is less than the preset torque, and the vehicle speed is less than the preset speed, then the fourth energy recovery activation condition is met.

[0081] In addition to the three situations mentioned above, there is also the case where, when returning to a straight line from a curve, the suspension, tires, and steering system themselves can cause the vehicle to have a self-centering effect even when no one is turning the steering wheel. This excess self-centering force can also be recovered as energy.

[0082] To determine when the aforementioned energy can be recovered, it is necessary to determine the steering wheel angle and whether the steering wheel angle is at zero.

[0083] If the steering wheel is not at the zero position and the steering trend is towards the zero position, it indicates that the vehicle is returning to center. However, it is still uncertain whether the return to center is effective. Therefore, it is necessary to use the preset torque and steering wheel torque to make a judgment, and also to judge the vehicle speed and the preset driving speed.

[0084] If the steering wheel angle is not at zero and the steering trend is approaching zero, and the steering torque is less than the preset torque, and the vehicle speed is less than the preset speed, then it is determined that energy can be recovered from the excess return force, and the fourth energy recovery activation condition is met.

[0085] The preset driving speed can be the minimum vehicle speed during the automatic self-centering process, obtained through actual testing. The preset torque can be the minimum steering torque applied by the driver to the steering wheel during the automatic self-centering process, obtained through actual testing. The fourth energy recovery activation condition can be a criterion for determining whether to recover excess self-centering force.

[0086] S130. If satisfied, then activate steering energy recovery.

[0087] If a certain energy recovery start-up condition is determined to be met, the energy recovery device corresponding to the energy recovery start-up condition is activated, thereby recovering the turning energy.

[0088] Steering energy can be energy generated by vehicle steering that can be recovered. The energy recovery device can be a device installed in the vehicle to recover energy.

[0089] The technical solution of this invention determines whether the energy recovery activation conditions are met based on vehicle driving information and steering wheel information. This pre-emptive determination of whether energy recovery should be performed ensures that the driver's experience and safety are not affected during energy recovery. Through these steps, the energy recovery efficiency is improved, increasing the vehicle's range while simultaneously enhancing driving safety.

[0090] Example 2

[0091] Figure 2 This invention provides a flowchart of another method for determining energy recovery during steering wheel turn, based on the above embodiments. This embodiment further optimizes the subsequent process of determining whether to activate steering energy recovery if certain conditions are met, as described in the previous embodiments. This embodiment can be combined with various optional solutions from one or more of the above embodiments. Figure 2 As shown, the method for determining energy recovery during steering wheel turn in this embodiment may include the following steps:

[0092] S210. Obtain vehicle driving information and steering wheel steering information.

[0093] S220. Determine whether the conditions for starting energy recovery are met based on vehicle driving information and steering wheel information.

[0094] S230. If satisfied, then activate steering energy recovery.

[0095] S240. Determine whether the activated energy recovery device corresponds to the first energy recovery start-up condition.

[0096] S250, If yes, then determine to stop judging other energy recovery start conditions.

[0097] When the first energy recovery activation condition is met, if other energy recovery activation conditions are met simultaneously and the energy corresponding to those conditions is recovered, it may have a certain impact on the driver's driving experience and safety. This is because other vehicles, people, or obstacles may be present in the first energy recovery activation condition.

[0098] Therefore, the decision to stop should be based on other energy recovery start-up conditions to avoid this situation.

[0099] By employing the technical solution of this invention, it is determined whether the activated energy recovery device corresponds to the first energy recovery activation condition. If so, it is determined to stop judging other energy recovery activation conditions, so as to avoid affecting the driver's driving experience and safety when recovering steering energy.
