Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle status display system, method, device and storage medium. Background Technology

[0002] With the current trend of user-controlled and intelligent assisted driving developing in parallel, adaptive cruise control systems have been widely adopted. Adaptive cruise control is a new system that adds a function to maintain a reasonable distance from the vehicle in front, building upon the existing cruise control system that maintains a set speed. During driving, when the distance between the vehicle and the vehicle in front is greater than a safe distance, the vehicle continues at the set speed. However, if the distance between the vehicle and the vehicle in front decreases due to braking, malfunction, or other reasons, the vehicle needs to brake and decelerate to ensure user safety. Therefore, how to provide users with information about the vehicle's braking status during braking and deceleration, thereby avoiding anxiety and unease for the user, has become a pressing issue that needs to be addressed.

[0059] To make the technical solution and advantages of this application clearer, the embodiments of this application will be described in further detail below.

[0060] The terms "first," "second," "third," and "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order.

[0061] It should be noted that all information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.), and signals involved in this application have been authorized by the user or fully authorized by all parties, and the collection, use, and processing of related data must comply with the relevant laws, regulations, and standards of the relevant countries and regions. For example, the speed, deceleration, and path involved in this application were obtained with full authorization.

[0062] Figure 1 This is a schematic diagram of a vehicle status display system provided in an embodiment of this application. See also... Figure 1 The system includes: a control device 101, a braking device 102, and an in-vehicle display device 103; wherein the control device 101, the braking device 102, and the in-vehicle display device 103 are all located inside the first vehicle, and the braking device 102 and the in-vehicle display device 103 are all electrically connected to the control device 101.

[0063] The control device 101 is used to acquire a first speed of a first vehicle, a second speed of a second vehicle, and a first distance between the first vehicle and the second vehicle; wherein the second vehicle is a vehicle located in front of the first vehicle in the direction of travel, and the first speed is the set speed of the adaptive cruise control.

[0064] The control device 101 is also configured to, when the first speed is greater than the second speed, determine a first speed difference based on the first speed and the second speed; determine a deceleration based on the first distance and the first speed difference, and send the deceleration to the braking device 102 and the vehicle display device 103;

[0065] The control device 101 is also used to determine the braking path and send the braking path to the vehicle display device 103;

[0066] Braking device 102 is used to determine braking pressure based on deceleration; and to control the braking and deceleration of the first vehicle based on the braking pressure.

[0067] The vehicle-mounted display device 103 is used to determine the first color corresponding to the deceleration, display a first virtual image, a second virtual image, and display the braking path through the first color on the instrument panel of the first vehicle; wherein, the first virtual image is the virtual image corresponding to the first vehicle, and the second virtual image is the virtual image corresponding to the second vehicle.

[0068] In the embodiments of this application, the electrical connection can be a circuit connection or a wireless connection, and there is no specific limitation on the latter. If the electrical connection is a circuit connection, the connection method can be a cable connection; if the electrical connection is a wireless connection, the connection method can be a wireless network connection. Furthermore, the vehicles in the embodiments of this application, such as the first vehicle, the second vehicle, and the third vehicle, can be fuel-powered vehicles, electric vehicles, or hybrid vehicles, and there is no specific limitation on the latter.

[0069] In this embodiment, the control device 101 is a domain controller of an ADAS (Advanced Driving Assistance System). It can acquire the first speed of the first vehicle, the second speed of the second vehicle, and the first distance between the first and second vehicles through cameras and radar installed on the first vehicle, and determine the deceleration based on the first speed, the second speed, and the first distance. The braking device 102 is a control unit in the braking system, which can control the braking and deceleration of the first vehicle based on the deceleration.

[0070] The control device 101 can also determine the braking path and send the deceleration and braking path to the vehicle display device 103. The vehicle display device 103 determines the first color corresponding to the deceleration and displays the braking path of the first vehicle on the instrument panel using the first color. In this way, when the vehicle brakes, the driver can clearly know the braking status of the vehicle through the instrument panel, such as when the vehicle starts braking and when the braking ends, thereby avoiding anxiety and unease for the driver.

[0071] The process of determining the deceleration by control device 101 will be introduced below.

[0072] The camera on the first vehicle can capture images of the area in front of the first vehicle in real time or periodically and send the captured images to the control device 101. The control device 101 then identifies the vehicle in front of the first vehicle as the second vehicle based on these images. The first speed is the set speed for adaptive cruise control, which the control device 101 can obtain. Additionally, the control device 101 can obtain the second speed of the second vehicle and the first distance between the first and second vehicles via the radar on the first vehicle.

[0073] The second speed can be 0 or not. If the second speed is 0, it means that the second vehicle is stationary; if the second speed is not 0, it means that the second vehicle is in motion.

[0074] After acquiring the first speed, the second speed, and the first distance, the control device 101 can determine whether the first speed is greater than the second speed. If the first speed is greater than the second speed, the first speed difference is determined based on the first speed and the second speed; and the deceleration is determined based on the first distance and the first speed difference.

[0075] The control device 101 can acquire the braking distance, which is no greater than a first distance; determine the ratio of the square of the first speed difference to the braking distance, and determine that half of this ratio is the deceleration. The control device 101 can pre-store the correspondence between speed and braking distance, and then determine the braking distance corresponding to the first speed based on this correspondence. Alternatively, the control device 101 can pre-store the correspondence between speed range and braking distance, first determining the speed range within which the first speed falls, and then determining the braking distance corresponding to that speed range based on this correspondence. The braking distance is the distance traveled by the first vehicle from the first speed until its speed drops to a second speed.

[0076] After determining the deceleration, the control device 101 sends the deceleration value to the braking device 102. Based on the deceleration, the braking device 102 determines the braking pressure; based on the braking pressure, it controls the first vehicle to brake and decelerate. Specifically, the braking device 102 can determine the product of the mass of the first vehicle and the deceleration to obtain the braking pressure, and based on the braking pressure, control the first vehicle to brake and decelerate.

[0077] The process of generating the braking path by the control device 101 is described below.

[0078] The control device 101 determines the braking start point and braking end point based on the first position of the first vehicle, the second position of the second vehicle, and the braking distance; and generates a braking path based on the braking start point and braking end point.

[0079] The control device 101 can determine the braking start point and braking end point between the first vehicle and the second vehicle based on the first position, the second position and the braking distance. The distance between the braking start point and the braking end point is the braking distance, and the path between the braking start point and the braking end point is determined as the braking path.

[0080] See Figure 2 ,from Figure 2 As can be seen from this: the distance between the first vehicle and the second vehicle is the first distance; after traveling a certain distance, the first vehicle will brake and decelerate until its speed is the same as the second speed. The distance traveled by the first vehicle from the start of braking and deceleration until its speed is the same as the second speed is the braking distance.

[0081] In this embodiment, the control device 101 sends deceleration and braking path to the vehicle display device 103. The control device 101 may send deceleration and braking path simultaneously, or it may send deceleration first and then the braking path; there is no specific limitation on this.

[0082] After receiving the deceleration and braking path, the vehicle-mounted display device 103 can first determine the first color corresponding to the deceleration, and then display a first virtual image, a second virtual image, and the braking path through the first color on the instrument panel of the first vehicle. The first virtual image is the virtual image corresponding to the first vehicle, and the second virtual image is the virtual image corresponding to the second vehicle.

[0083] The process by which the vehicle display device 103 determines the first color corresponding to the deceleration can be as follows: the vehicle display device 103 determines the deceleration range in which the deceleration is located; based on the correspondence between the deceleration range and the color, the first color corresponding to the deceleration range is determined.

[0084] For example, a deceleration of 0.2g or less falls within the first deceleration range, corresponding to a light green color. A deceleration greater than 0.2g but less than 0.4g falls within the second deceleration range, corresponding to a green color. A deceleration greater than or equal to 0.4g falls within the third deceleration range, corresponding to a dark green color. Here, g is the acceleration due to gravity.

[0085] It should be noted that when no braking deceleration occurs, the in-vehicle display device 103 can display the first distance between the first and second vehicles on the instrument panel using a target color. When braking deceleration occurs, the in-vehicle display device 103 displays the braking path on the instrument panel using a first color. Since the braking path is no greater than the first distance, part of the instrument panel will display the target color, and the other part will display the first color. See also... Figure 2 .

[0086] For example, if the target color is blue and the primary color is light green, then the instrument panel will display part blue and part light green.

[0087] Another point to note is that when the second speed is not zero, it indicates that the second vehicle is in motion. Therefore, during the braking and deceleration process of the first vehicle, the second speed may change, for example, increase or decrease. Therefore, in this embodiment, the control device 101 determines the deceleration and braking path in real time or periodically based on the first speed, the second speed, and the first distance. When the range of deceleration or the braking path changes, the vehicle display device 103 re-determines the color corresponding to the changed deceleration range and displays the braking path or the changed braking path using the re-determined color. Thus, the process of the vehicle display device 103 displaying the braking path on the instrument panel using color is a continuous process, and the colors on the instrument panel change dynamically.

[0088] See Figure 3 The control device 101 acquires a second speed and a first distance via radar and a camera. Based on the first speed, the second speed, and the first distance, the control device 101 determines the deceleration and sends a deceleration request to the braking device 102, the deceleration request carrying the deceleration. The control device 101 also determines the braking path and sends the braking path to the vehicle display device 103.

[0089] The braking device 102 controls the first vehicle to brake and decelerate based on the deceleration rate. During the braking and deceleration process, the braking device 102 can send the speed of the first vehicle to the control device 101 in real time or periodically. The control device 101 then re-determines the deceleration rate based on the speed of the first vehicle. The on-board display device 103 displays the braking path on the instrument panel using corresponding colors based on the braking path.

[0090] In this embodiment, the vehicle display device 103 also includes a vehicle display screen. The vehicle display device 103 can also display a first virtual image, a second virtual image, and a braking path through a first color on the vehicle display screen. In this way, passengers in the first vehicle can clearly obtain the braking status of the vehicle by observing the vehicle display screen, thus avoiding anxiety and unease.

[0091] Of course, the in-vehicle display device 103 can also display the corresponding deceleration on the instrument panel and the in-vehicle display screen, so that the driver and passengers can clearly obtain the magnitude of the deceleration.

[0092] In this embodiment, the control device 101 can also output voice messages via a voice device to remind the driver and passengers in the vehicle. Accordingly, the system further includes a voice device, with the control device 101 electrically connected to the voice device.

[0093] Control device 101 is further configured to determine a second distance between the braking initiation point and the first position; determine a first time based on the first speed difference and the second distance, the first time being the time taken for the first vehicle to travel from the first position to the braking initiation point; and send at least one of the second distance and the first time to a voice device.

[0094] A voice device for outputting a voice message based on at least one of a second distance and a first time.

[0095] In this implementation, the control device 101 first determines a second distance between the braking initiation point and the first position currently occupied by the first vehicle. Then, it determines the ratio of the second distance to the first speed difference to obtain a first time interval. It then sends at least one of the second distance and the first time interval to the voice device. The voice device outputs a voice message carrying at least one of the second distance and the first time interval. For example, if the second distance is 30 meters, the voice message could be, "Deceleration is expected to begin in 30 meters; please prepare." Similarly, if the first time interval is 2 seconds, the voice message could be, "Deceleration is expected to begin in 2 seconds; please prepare."

[0096] This application provides a vehicle status display system. In this system, a control device 101 determines a deceleration based on a first speed of a first vehicle, a second speed of a second vehicle, and a first distance between the two vehicles, and sends the deceleration information to a braking device 102 and an in-vehicle display device 103. Furthermore, the control device 101 determines a braking path and sends the braking path to the in-vehicle display device 103. The braking device 102 determines the braking pressure based on the deceleration and controls the first vehicle to brake and decelerate based on the braking pressure. The in-vehicle display device 103 determines a first color corresponding to the deceleration and displays the braking path on the instrument panel of the first vehicle using the first color. Therefore, by displaying the braking path during the vehicle's braking process on the instrument panel, this system allows the user to clearly understand the vehicle's braking status, thereby avoiding anxiety and unease.

[0097] In this embodiment, the in-vehicle display device shows the pressure build-up point of the vehicle's impending braking and displays different colors according to the magnitude of the deceleration, providing real-time alerts to the driver regarding the vehicle's status. This allows the driver to clearly understand the vehicle's status in real time, reducing unnecessary worries and tension, enhancing safety, and improving the driving experience of the adaptive cruise control function.

[0098] The above mainly describes the braking process of the first vehicle when its initial speed is greater than the second speed of the second vehicle in front of it. In practical applications, there may also be vehicles behind the first vehicle, such as a third vehicle. The following describes how to avoid a collision between the first vehicle and the third vehicle when the third speed of the third vehicle is greater than the first speed of the first vehicle.

[0099] The control device 101 is also used to acquire the third speed of the third vehicle and the third distance between the first vehicle and the third vehicle; wherein the third vehicle is a vehicle located behind the first vehicle in the direction of travel.

[0100] The control device 101 is also used to determine the driving path of the first vehicle when the third speed is greater than the first speed and the third distance is less than the first preset distance; and to control the driving of the first vehicle based on the driving path.

[0101] The control device 101 is also used to send the driving path to the vehicle display device 103;

[0102] The in-vehicle display device 103 is also used to display a third virtual image on the instrument panel of the first vehicle and to display the driving path through a second color; wherein the third virtual image is a virtual image corresponding to the third vehicle.

[0103] The control device 101 can acquire a third speed and a third distance using radar on the first vehicle, and then determine whether the third speed is greater than the first speed and whether the third distance is less than a first preset distance. If the third speed is greater than the first speed and the third distance is less than the first preset distance, there is a risk of collision between the third vehicle and the first vehicle. In this case, the control device 101 can determine the driving path of the first vehicle using any of the following implementation methods.

[0104] In the first implementation, the control device 101 determines whether there is a second vehicle in front of the first vehicle. If there is no second vehicle, the control device 101 determines the acceleration and driving path based on the first speed and the third speed.

[0105] In this implementation, the control device 101 determines the second speed difference between the first speed and the third speed, determines the ratio of the second distance to the second speed difference, and obtains the second time; determines the ratio of the second speed difference to the second time, and obtains the acceleration; and generates a driving path based on the acceleration, the first speed, and the third speed.

[0106] Specifically, the control device 101 determines the difference between the square of the third speed and the square of the first speed, determines the ratio of this difference to the acceleration, and sets half of this ratio as the acceleration distance. Based on the first vehicle's current first position and this acceleration distance, a driving path is generated.

[0107] The control device 101 sends the acceleration and driving path to the vehicle display device 103. The vehicle display device 103 determines the second color corresponding to the acceleration and displays the first virtual image, the third virtual image, and the driving path on the instrument panel using the second color. The method by which the control device 101 determines the second color corresponding to the acceleration is the same as the method by which it determines the first color corresponding to the deceleration, and will not be described again here.

[0108] In the second implementation, if a second vehicle exists, the control device 101 determines whether the first distance is greater than a second preset distance. If the first distance is greater than the second preset distance, it indicates that there is sufficient acceleration space between the first vehicle and the second vehicle. The control device 101 then determines the acceleration start point and acceleration end point based on the first position, the second position, and the acceleration distance; and generates a driving path based on the acceleration start point and acceleration end point. The acceleration distance is not greater than the first distance.

[0109] In this implementation, the method by which the control device 101 determines the acceleration distance is the same as that in the first implementation, and will not be repeated here. The first speed is not greater than the second speed.

[0110] After determining the acceleration distance, the control device 101 determines the acceleration start point and acceleration end point between the first vehicle and the second vehicle based on the first position, the second position, and the acceleration distance. The distance between the acceleration start point and the acceleration end point is the acceleration distance, and the path between the acceleration start point and the acceleration end point is determined as the driving path. After determining the driving path, the control device 101 controls the first vehicle to start accelerating from the acceleration start point based on the driving path.

[0111] Furthermore, the in-vehicle display device 103 can also display acceleration and driving path on the instrument panel using a second color.

[0112] In the third implementation, if a second vehicle exists and the first distance is not greater than the second preset distance, it indicates that there is insufficient acceleration space between the first vehicle and the second vehicle. In this case, the control device 101 can determine the vehicle condition of the target lane. The target lane is the adjacent lane of the current lane where the first vehicle is located. If the vehicle condition of the target lane meets the lane-changing conditions, a driving path is generated based on the current lane and the target lane. This driving path is used to represent the path of the first vehicle from the current lane to the target lane.

[0113] In this implementation, the control device 101 can acquire the vehicle condition of the target lane through a camera and radar, and then determine whether the vehicle condition of the target lane meets the lane change conditions. If the lane change conditions are met, the control device 101 determines the third position of the first vehicle in the target lane after changing lanes based on the first position of the first vehicle in the current lane, and generates a driving path based on the first position and the third position.

[0114] After determining the driving path, the control device 101 controls the first vehicle to move from the current lane into the target lane based on the driving path. Furthermore, the in-vehicle display device 103 can also display the driving path on the instrument panel using a second color.

[0115] If the lane-changing conditions are not met, the control device 101 can control the first vehicle to cross lanes, thereby avoiding a collision between the first vehicle and the third vehicle. After determining that the first vehicle will not collide with the third vehicle, the control device 101 controls the first vehicle to return to the current lane.

[0116] In this embodiment, when the third vehicle's third speed is greater than the first vehicle's first speed, a collision may occur between the third vehicle and the first vehicle. In this case, the control device 101 can control the first vehicle to accelerate or change lanes, thereby avoiding a collision, ensuring user safety, and preventing user anxiety.

[0121] Step 403: The control device determines the braking path and sends the braking path to the vehicle display device.

[0122] Step 404: The braking device determines the braking pressure based on the deceleration; based on the braking pressure, it controls the braking and deceleration of the first vehicle.

[0123] Step 405: The vehicle display device determines the first color corresponding to the deceleration, and displays the first virtual image, the second virtual image, and the braking path through the first color on the instrument panel of the first vehicle.

[0124] The first virtual image is the virtual image corresponding to the first vehicle, and the second virtual image is the virtual image corresponding to the second vehicle.
