[0002] As the popularity of vehicles increases, the pre-parking platform industry is booming. When a vehicle enters the predetermined position, the vehicle transfer vehicle automatically completes the parking work such as vehicle transfer. In the vehicle status detection, the detection of the tightening state of the vehicle's handbrake is extremely important, because only after the handbrake is tightened can the vehicle accurately maintain its position and be stably transferred to the parking space by the transfer vehicle.

[0003] However, nowadays, when testing the braking condition of a vehicle, a fixed thrust is usually used to push the vehicle to determine whether the handbrake of the vehicle has been pulled. On the one hand, this method may cause damage to the vehicle due to excessive thrust. On the other hand, it may cause detection errors due to insufficient thrust, resulting in failure to push heavier vehicles. This greatly increases the safety risks of vehicle parking.

[0025] According to the displacement sensor provided on the pushing component, the displacement distance of the pushing component is acquired, and it is determined whether the displacement distance of the pushing component is greater than a braking threshold.

[0052] See also Figure 1 , Figure 1 A flow chart of a method for detecting a vehicle braking condition according to an embodiment of the present application is shown. The present application embodiment provides a method for detecting a vehicle braking condition, comprising:

[0053] Step S110, obtaining the weight value of the parked vehicle, wherein a pushing component for pushing the vehicle to detect the braking condition is provided in the parking area of ​​the vehicle;

[0054] Step S120, calculating the thrust value of the pushing component according to the weight value of the vehicle, wherein the thrust value is positively correlated with the weight value;

[0055] Step S130, driving a pushing component to push the vehicle according to the thrust value;

[0056] Step S140, determining the braking condition of the vehicle according to the displacement distance of the pushing component.

[0057] The above four steps are described in detail below.

[0058] In step S110, the vehicle is parked in a parking area provided with a push component, and after the vehicle is parked, the weight value of the vehicle is obtained. The weight value of the vehicle can be obtained by weighing the vehicle using a weighing device provided on the ground of the parking area.

[0059] In step S120, the weight value of the vehicle is substituted into a preset thrust value calculation formula to calculate a thrust value that matches the weight value. It should be clear that the thrust value is positively correlated with the weight value, that is, the greater the weight value of the vehicle, the greater the thrust value that is adapted to it.

[0060] For details, please refer to Figure 2 , Figure 2 A flowchart of calculating the thrust value of the push component according to the weight value of the vehicle according to an embodiment of the present application is shown. The present application embodiment provides a step S120 of calculating the thrust value of the push component according to the weight value of the vehicle, including:

[0061] Step S121, obtaining the vehicle's eccentric load coefficient according to the vehicle's weight distribution;

[0062] Step S122, summarizing the environmental factors of the parking place of the vehicle and the eccentric load coefficient of the vehicle to obtain the braking factor of the vehicle;

[0063] Step S123, calculating and obtaining the thrust value of the pushing component according to the braking factor and the weight value.

[0064] The above three steps are described in detail below.

[0065] In step S121, for obtaining the weight distribution of the vehicle, multiple weighing devices can be respectively set in the parking area to obtain the weight value carried by each wheel of the vehicle, and the weight value carried by each wheel is compared to determine whether the center of gravity of the vehicle is offset. When the weight value carried by the front wheel of the vehicle is greater than or less than the weight value carried by the rear wheel, it means that the center of gravity of the vehicle is offset forward or backward. When the weight value carried by the left wheel of the vehicle is greater than or less than the weight value carried by the right wheel, it means that the center of gravity of the vehicle is offset to the left or to the right.

[0066] The vehicle's eccentric load coefficient is determined according to the offset of the vehicle's center of gravity. In one embodiment of the present application, the vehicle's eccentric load coefficient is calculated according to the weight value carried by each tire of the vehicle. For example, the vehicle's eccentric load coefficient is calculated according to the ratio of the weight value carried by the front wheels and the rear wheels of the vehicle, or according to the ratio of the weight value carried by the left wheel and the right wheel of the vehicle. The eccentric load coefficient is used to adjust the thrust value adapted by the push component.

[0067] Exemplarily, in one embodiment of the present application, the pushing component is arranged in front of the front wheel of the vehicle, and the braking condition of the vehicle is determined by pushing the front wheel of the vehicle. It should be clear that the number of the pushing components in the embodiment of the present application includes but is not limited to one.

[0068] The weight values ​​carried by the front wheels of the vehicle are added together to obtain the front wheel load value, and the weight values ​​carried by the rear wheels of the vehicle are added together to obtain the rear wheel load value. If the front wheel load value is greater than the rear wheel load value, the center of gravity of the vehicle is shifted forward. If the front wheel load value is less than the rear wheel load value, the center of gravity of the vehicle is shifted backward. The ratio of the front wheel load value to the rear wheel load value is used as the vehicle load factor.

[0069] Similarly, the weight values ​​carried by the left wheels of the vehicle are added together to obtain the weight value of the left wheels, and the weight values ​​carried by the right wheels of the vehicle are added together to obtain the weight value of the right wheels. If the weight value carried by the left wheels is greater than the weight value carried by the right wheels, the center of gravity of the vehicle is offset to the left. If the weight value carried by the left wheels is less than the weight value carried by the right wheels, the center of gravity of the vehicle is offset backward, and the ratio of the weight value carried by the left wheels to the weight value carried by the right wheels is used as the vehicle's eccentric load coefficient.

[0070] If the center of gravity of the vehicle is shifted forward, the weight carried by the front wheels will be greater. Compared with the case where the center of gravity of the vehicle is not shifted, the unbalanced load factor will make the vehicle adapt to a larger thrust value.

[0071] If the center of gravity of the vehicle is shifted rearward, the eccentric load factor will cause the vehicle to adapt to a smaller thrust value.

[0072] When the number of the pushing component is one and it is located in front of the left front wheel of the vehicle.

[0073] If the center of gravity of the vehicle is shifted to the right, and the weight carried by the left front wheel of the vehicle is lower, the unbalanced load factor will make the vehicle adapt to a smaller thrust value.

[0074] If the center of gravity of the vehicle shifts to the left and the weight carried by the left front wheel of the vehicle is larger, the unbalanced load factor will make the vehicle adapt to a larger thrust value.

[0075] In another embodiment of the present application, the weight values ​​carried by each wheel of the vehicle are obtained respectively according to a plurality of weighing devices arranged in the parking area, and their average weight value is obtained to determine the weight value carried by each wheel when the center of gravity of the vehicle is not offset. Then, the weight value carried by the wheel adapted to the push component is compared with the average weight value. The ratio of the weight value carried by the wheel adapted to the push component to the average weight value can be used as an eccentric load coefficient to calculate the thrust value as an element of thrust value calculation.

[0076] If the weight value carried by the wheel adapted to the pushing component is greater than the average weight value, it means that the weight value carried by the wheel is large. Substituting the corresponding eccentric load coefficient into the preset thrust value calculation formula will make the pushing component adapt to a larger thrust value.

[0077] In step S122, environmental factors of the parking area are obtained. Environmental factors are factors that affect the calculation of the thrust value, such as the inclination angle of the parking area, the friction coefficient of the surface, and the angle between the vehicle and the pushing component.

[0078] Specifically, the inclination angle of the parking area will affect the center of gravity position of the vehicle.

[0079] The surface friction coefficient affects the maximum friction between the vehicle and the ground. The higher the friction coefficient, the greater the thrust value required.

[0080] The angle between the vehicle and the pushing component will affect the effect of the thrust. When they are in a straight line, such as the pushing component is directly in front of the wheel, the thrust generated by the pushing component will act completely on the wheel. If the pushing component and the wheel are not in a straight line, the thrust will not be able to act completely on the wheel. At this time, the thrust of the pushing component needs to be increased.

[0081] It also includes a rolling resistance coefficient and a thrust addition coefficient obtained through multiple calculations, so as to adjust the thrust value so that the thrust generated by the pushing component is more suitable for the parked vehicle.

[0082] The environmental factors of the vehicle parking area and the vehicle's eccentric load coefficient are summarized to obtain the braking factors that affect the thrust value.

[0083] In step S123, the obtained braking factor and the weight value of the vehicle are substituted into a preset thrust value calculation formula to obtain the thrust value corresponding to the vehicle.

[0084] In step S130, according to the calculated thrust value, the pushing component is driven to push the vehicle with a thrust equal to the thrust value. It should be clear that, depending on the different structures of the pushing component, the pushing component can push the wheels, front bumper, rear bumper, etc. of the vehicle.

[0085] See also Figure 3 , Figure 3 A schematic diagram of a push component and a driving device according to an embodiment of the present application is shown. The driving device includes a first hydraulic rod and a second hydraulic rod, and a first limit switch for limiting the displacement distance of the first hydraulic rod and a second limit switch for limiting the displacement distance of the second hydraulic rod.

[0086] See also Figure 4 , Figure 4 A flowchart of driving a pushing component to push a vehicle according to a thrust value according to an embodiment of the present application is shown. The present application embodiment provides a step S130 of driving a pushing component to push a vehicle according to a thrust value, including:

[0087] Step S131, driving the first hydraulic rod to rise vertically to push the pushing component to rise to a set height;

[0088] Step S132, driving the second hydraulic rod to push the pushing component in the horizontal direction, and pushing it toward the vehicle with a thrust force equal to the thrust value.

[0089] The above two steps are described in detail below.

[0090] In step S131, the first hydraulic rod is driven to rise vertically, and the second hydraulic rod and the pushing component are pushed to a set height, and the rise is stopped. The set height can be generated based on user definition, or based on the height of the vehicle or the height of the vehicle wheels.

[0091] In one embodiment of the present application, a first limit switch is set to control the lifting height of the first hydraulic rod, and the first hydraulic rod is driven to perform vertical lifting until the first limit switch is triggered, which means that the first hydraulic rod has risen to the set height.

[0092] In step S132, according to the acquired thrust value, the second hydraulic rod is driven with a thrust equal to the thrust value to horizontally push the pushing component toward the vehicle.

[0093] In step S140, after the pushing component is driven to push the vehicle, the moving distance of the pushing component is obtained, and finally the braking condition of the vehicle is determined according to the displacement distance of the pushing component.

[0094] Specifically, in one embodiment of the present application, the pushing component is driven to move horizontally. After the pushing component cannot move, the displacement distance of the pushing component is obtained. If the displacement distance of the pushing component is less than or equal to the braking threshold, it means that the vehicle is not pushed, that is, the vehicle is in a braking state at this time. If the displacement distance of the pushing component is greater than the braking threshold, it means that the vehicle is pushed, that is, the vehicle is in an unbraked state at this time.

[0095] The braking threshold may be the distance from the pushing component to the vehicle. When the displacement distance of the pushing component is equal to the braking threshold, that is, the pushing component does not move after contacting the vehicle, it means that the vehicle is in a braking state. If the displacement distance of the pushing component is greater than the braking threshold, it means that the pushing component has pushed the vehicle, that is, the vehicle is not in a braking state.

[0096] As for when to obtain the displacement distance of the pushing component, the displacement distance of the second hydraulic rod, that is, the displacement distance of the pushing component, can be obtained when the pushing component cannot move.

[0097] The displacement distance of the pushing component can also be obtained after a set time, because after the set time, no matter whether the pushing component pushes the vehicle or not, it will be in a stationary state, and the pushing component has completed the pushing task.

[0098] For obtaining the displacement distance of the pushing component, the displacement distance of the pushing component can be obtained according to the displacement sensor provided on the pushing component. Because the pushing component moves with the movement of the second hydraulic rod, the displacement distance of the pushing component can also be obtained according to the displacement distance of the second hydraulic rod.

[0099] After obtaining the displacement distance of the pushing component, the displacement distance of the pushing component is compared with the braking threshold. If the displacement distance of the pushing component is greater than the braking threshold, it is determined that the vehicle is in an unbraking state. If the displacement distance of the pushing component is less than or equal to the braking threshold, it is determined that the vehicle is in a braking state.

[0100] In another embodiment of the present application, the following method can also be used to determine whether the displacement distance of the push component is greater than the braking threshold: if the second hydraulic rod triggers the second limit switch, that is, the push component reaches the maximum displacement distance, it means that the vehicle has been pushed. Directly determine that the displacement distance of the push component is greater than the braking threshold, that is, the vehicle is in a non-braking state. It should be clear that when the second hydraulic rod triggers the second limit switch, the displacement distance of the push component is greater than the braking threshold.

[0101] When it is determined that the vehicle is in a non-braking state, the warning device is controlled to emit an alarm sound or an alarm light to prompt that the vehicle is currently in a non-braking state.
