For example, when the vehicle travels on a highway at a speed of 110 km/h, the radar module 01 detects that the left side of the vehicle is a fence and travels for 20 seconds continuously, and requests to enter the sleep mode. The central control module 02 receives current position information, vehicle speed information and static obstacle information of the vehicle at the same time, under the current working condition, the risk that the vehicle overtakes from the left side does not exist, and the radar on the right side normally works, the central control module 02 judges that the radar can be in a dormant state, a message is sent to the radar module 01, and after the radar module 01 receives the message, the blind area detection and merging auxiliary system is controlled to enter a dormant mode.
In addition, in order to ensure that the blind area detection and doubling auxiliary system operates normally, each associated system of the blind area detection and doubling auxiliary system diagnoses and monitors the messages of the blind area detection and doubling auxiliary system, taking a vehicle instrument as an example, when the instrument does not receive the messages of the blind area detection and doubling auxiliary system for 10 periods, the blind area detection and doubling auxiliary system is considered to be overtime, and a fault lamp of the blind area detection and doubling auxiliary system is lightened. For the above reasons, the blind area detection and wire combination auxiliary system needs to continuously send multi-frame messages before entering the sleep mode, which indicates that the blind area detection and wire combination auxiliary system is about to enter the sleep mode, and the instrument of the vehicle stops monitoring the blind area detection and wire combination auxiliary system after receiving the continuous multi-frame messages.
According to the sleep control method provided by the embodiment of the invention, when the state of an ignition switch of a vehicle is a starting state, the vehicle position information, the vehicle speed information and the static obstacle information of the vehicle are acquired, whether a blind area detection doubling auxiliary system meets a preset sleep condition or not is determined according to at least one of the vehicle position information, the vehicle speed information and the static obstacle information, and the blind area detection doubling auxiliary system is controlled to enter a sleep mode under the condition that the blind area detection doubling auxiliary system meets the preset sleep condition. When the vehicle continuously runs along static obstacles such as a tunnel, an isolation zone and the like, the blind area detection and doubling auxiliary system can enter a sleep mode, false alarm of the blind area detection and doubling auxiliary system is avoided, and the power consumption of the whole vehicle is reduced when the vehicle enters the sleep mode.
Referring to fig. 3, a flowchart illustrating steps of a trailer control method according to a second embodiment of the present invention is shown, where the sleep control method is applicable to a vehicle equipped with a blind area detection and merging assist system, where the blind area detection and merging assist system includes a central control module.
As shown in fig. 3, the sleep control method may specifically include the following steps:
step 201: when the state of an ignition switch of a vehicle is an activated state, vehicle position information, vehicle speed information, and stationary obstacle information of the vehicle are acquired.
In the embodiment of the present invention, referring to fig. 2, the map positioning module 03 may monitor the position information of the vehicle in real time, the map data records that the road where the vehicle is located has several lanes, sends the information of the lane where the vehicle is located on the current road, and sends the information to the in-vehicle local area network in the form of a message, and after receiving the position information of the vehicle, the blind area detection and merging auxiliary system determines whether the vehicle is located in lanes on both sides (the leftmost lane or the rightmost lane).
The radar module 01 receives vehicle speed information from the sensor actuator module 04 and indicates that the vehicle speed information is outside the preset vehicle speed information range when the vehicle speed information is below a maximum vehicle speed calibration value (Va) or above a minimum vehicle speed calibration value (Vb).
The radar module 01 processes the collected static obstacle information, wherein each static obstacle includes at least one original target point, and each static obstacle includes height information, lateral distance information, longitudinal distance information, and speed information. The static barrier can be a fence, a separation belt and the like.
When the state of the ignition switch of the vehicle is the activated state, the vehicle position information, the vehicle speed information, and the stationary obstacle information of the vehicle are acquired, and then step 202 is executed.
Step 202: and determining whether the blind area detection doubling auxiliary system meets a preset dormancy condition according to at least one of vehicle position information, vehicle speed information and static obstacle information.
In an embodiment of the present invention, the blind area detection and line doubling auxiliary system includes a radar, and the specific implementation manner of the step 202 may include:
substep 2021: acquiring front road attribute information of a vehicle; the front road attribute information includes at least one of an intersection and a lane entry.
Referring to fig. 2, the map positioning module 03 obtains the attribute information of the road ahead of the vehicle, including whether there is an intersection in the front of the vehicle, whether there is a lane entry, and the like, and after receiving the attribute information of the road ahead, the radar module 01 performs the following substep 2022.
Substep 2022: and determining the preset running time according to the front road attribute information.
The preset running time may be 2 seconds or 3 seconds, and may be set according to a specific application scenario, which is not limited in the embodiment of the present invention.
Substep 2023: and when the vehicle position information indicates that the vehicle is located in the rightmost lane or the leftmost lane, the vehicle speed information is out of the preset vehicle speed information range, and the continuous running time of the vehicle along the extending direction of the corresponding static obstacle in the static obstacle information exceeds the preset running time, determining that the radar of the blind area detection and merging auxiliary system meets the preset dormancy condition.
The continuous running time of the vehicle is the time when the vehicle runs to the front intersection, and can be calculated by dividing the distance between the vehicle and the front intersection by the vehicle speed. And when the continuous running time of the vehicle is less than the preset running time, the radar is prohibited from entering the sleep mode.
Wherein, the radar can include left side radar and right side radar, and the leftmost lane corresponds the left side radar, and the rightmost lane corresponds the right side radar, and in practical application, can be according to specific application scenario down, the vehicle is gone along the leftmost lane or the rightmost lane is gone, comes the radar of this corresponding side of control to get into the dormant mode.
It should be further noted that the left-side radar and the right-side radar have a beam overlapping region behind the vehicle, and target data of the left-side radar and the right-side radar need to be fused for target judgment in the overlapping region, so that the blind area detection parallel line auxiliary system needs to provide two groups of target lists, fuse target data and single-side radar detection data, respectively give different weights to the two groups of target lists, and call different target lists according to whether the radar on the other side is dormant, so as to realize normal operation of the radar on the other side which is not dormant.
It should be noted that, when the vehicle speed is lower than the minimum vehicle speed calibration value (Vb), and the radar module 01 detects that the distance between the vehicle and the fence is always kept constant, which indicates that the vehicle is in a non-driving state at this time, the radar on the side close to the fence meets the preset sleep condition.
Step 203: and receiving a sleep mode entering instruction sent by the central control module under the condition that the blind area detection doubling auxiliary system meets a preset sleep condition.
In the embodiment of the invention, referring to fig. 2, when the blind area detection doubling auxiliary system meets the preset dormancy condition, the radar module 01 sends a message for applying to enter the dormancy mode to the central control module 02, the central control module 02 judges whether the radar module 01 is allowed to hibernate under the current working condition according to the current driving working condition of the vehicle after receiving the request for entering the dormancy mode, when the dormancy can be performed, the message is sent to the radar module 01, and the radar module 01 enters the dormancy mode after receiving the message containing the dormancy instruction.
Step 204: and after receiving the sleep mode instruction, controlling the blind area detection doubling auxiliary system to enter the sleep mode.
For example, when the vehicle travels on a highway at a speed of 110 km/h, the radar module 01 detects that the left side of the vehicle is a fence and travels for 20 seconds continuously, and requests to enter the sleep mode. The central control module 02 receives current position information, vehicle speed information and static obstacle information of the vehicle at the same time, under the current working condition, the risk that the vehicle overtakes from the left side does not exist, and the radar on the right side normally works, the central control module 02 judges that the radar can be in a dormant state, a message is sent to the radar module 01, and after the radar module 01 receives the message, the blind area detection and merging auxiliary system is controlled to enter a dormant mode.
Step 205: and when the state of an ignition switch of the vehicle is an off state and the time length of the vehicle in the off state is greater than or equal to the preset time length, controlling the blind area detection and doubling auxiliary system to enter a sleep mode.
When the state of an ignition switch of the vehicle is an OFF (OFF) gear, a radar module in the blind area detection and doubling auxiliary system starts timing, and when the preset time length is reached, the blind area detection and doubling auxiliary system enters a sleep mode.
The preset time may be two minutes, three minutes, or thirty minutes, and may be adjusted according to a specific application scenario, which is not limited in the embodiment of the present invention.
In addition, in the case of a power outage in the power supply line of the blind zone detection and doubling assistance system of the vehicle, the blind zone detection and doubling assistance system directly enters the sleep mode.
In the embodiment of the invention, when the state of an ignition switch of a vehicle is a starting state, vehicle position information, vehicle speed information and static obstacle information of the vehicle are acquired, whether a blind area detection parallel line auxiliary system meets a preset sleep condition or not is determined according to at least one of the vehicle position information, the vehicle speed information and the static obstacle information, a sleep mode entering instruction sent by a central control module is received under the condition that the blind area detection parallel line auxiliary system meets the preset sleep condition, the blind area detection parallel line auxiliary system is controlled to enter a sleep mode after the sleep mode instruction is received, and the blind area detection parallel line auxiliary system is controlled to enter the sleep mode when the state of the ignition switch of the vehicle is a closing state and the time length of the vehicle in the closing state is greater than or equal to the preset time length. When the vehicle continuously runs along static obstacles such as a tunnel, an isolation zone and the like, the blind area detection and doubling auxiliary system can enter a sleep mode, false alarm of the blind area detection and doubling auxiliary system is avoided, and the power consumption of the whole vehicle is reduced when the vehicle enters the sleep mode.
