Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In the present disclosure, the use of directional terms such as "front, rear, left, right" is generally relative to the direction in which the vehicle normally travels, unless otherwise specified.
FIG. 1 is a flow chart of an auto cruise control method provided by an exemplary embodiment. As shown in fig. 1, the method may include the steps of:
in step S11, the state information and the environmental information of the vehicle are acquired during the running of the vehicle.
Step S12, it is determined whether the driver is tired based on the state information.
And step S13, judging whether the road is clear according to the environment information.
In step S14, it is determined whether the vehicle has a history of auto cruise travel in the current link.
And step S15, if the driver is fatigue, the road is smooth and the vehicle has the history of automatic cruise running in the current road section, controlling to turn on the automatic cruise system so as to enable the vehicle to automatically cruise and run.
The state information of the vehicle may include, for example, vehicle speed, accelerator pedal opening, brake pedal opening, steering angle, and other information that can characterize the motion of the vehicle. Whether the driver is fatigued can be determined based on the state information of the vehicle. For example, if the vehicle continues to run for too long, the driver may be considered to be tired, or if the opening degree of the accelerator pedal remains unchanged for a long time, the driver may be considered to be tired when stepping on the accelerator pedal. The state information of the vehicle may be acquired from each controller or bus of the vehicle during the running of the vehicle, or may be directly acquired from a plurality of sensors.
The environmental information may include, for example, the number of surrounding vehicles, the speed and position of the surrounding vehicles, the degree of flatness of the road surface, and the like, which can characterize the environment in which the vehicle is located. Whether the road is smooth or not can be judged according to the environment information. For example, if the number of surrounding vehicles is small and the road is flat and spacious, the road may be considered to be clear. The detection of the surrounding vehicles can be realized by mounting a distance measuring device such as a radar on the vehicle.
If the driver is tired and the road is smooth, the driver can be considered to have the requirement of automatic cruising, and the safety of automatic cruising is higher.
In the vehicle, information such as a time period in which the automatic cruise system is operated, a vehicle position section, and the like may be stored each time the automatic cruise system is turned on. If the driver had manually turned on the auto-cruise system and the vehicle traveled a distance in a road segment, the vehicle had a history of auto-cruise travel in that road segment. If the vehicle has the history of automatic cruise driving in the current road section, the road section can be considered to basically have the automatic cruise condition, so that the condition is added on the basis that the driver is tired and the road is smooth, and the feasibility and the safety of the current automatic cruise are further clarified.
According to the technical scheme, when the driver is judged to be tired according to the state information of the vehicle, the road is judged to be smooth according to the environment information, and the vehicle has the history of automatic cruise driving in the current road section, the automatic cruise system is controlled to be opened. The automatic cruise control system has the advantages that the vehicle has the history of automatic cruise in the current road section, the suitability of automatic cruise on the current road can be guaranteed, the automatic cruise control system can be started under the condition that conditions are allowed and the vehicle has safety guarantee, the operation of a driver is not needed, the automation degree is high, and the automatic cruise control system is safe and reliable.
In fig. 1, step S12, step S13, and step S14 are executed synchronously, and may be executed in any other order in other embodiments.
In one embodiment, the status information may include vehicle operating duration, vehicle speed, and accelerator pedal opening. In this embodiment, the step of determining whether the driver is fatigued based on the state information (step S12) may include:
determining that the driver is fatigued if one or more of the following are met: after the power-on, the running time of the vehicle exceeds a preset first time, the duration of the vehicle speed being greater than the preset vehicle speed exceeds a preset second time, and the duration of the opening of the accelerator pedal kept in a preset range exceeds a preset third time.
Wherein the predetermined vehicle speed, the first duration, the second duration, and the third duration may be experimentally or empirically derived. For example, if the running time of the vehicle exceeds half an hour after the power-on, or the duration of the vehicle speed being greater than 60km/h exceeds fifteen minutes, or the duration of the opening degree of the accelerator pedal being maintained at one fifth of the full opening degree exceeds ten minutes, it is considered that the driver is fatigued.
In the embodiment, the condition for judging the fatigue of the driver is specifically limited, and the method is simple and easy to implement and high in reliability.
In another embodiment, the environmental information may include the distance of the vehicle from the surrounding vehicle, the speed of the surrounding vehicle. In this embodiment, the step of determining whether the road is clear according to the environment information (step S13) may include:
and if the distance between the vehicle and the surrounding vehicle is greater than a preset distance threshold value, and the relative speed between the surrounding vehicle and the vehicle is less than a preset speed threshold value, determining that the road is clear.
The distance threshold and the vehicle speed threshold can be obtained through experiments or experience. For example, if the distance between the vehicle and the vehicle ahead is greater than twenty meters and the relative vehicle speeds of the vehicle ahead and the vehicle are less than 5km/h, it is determined that the road is clear. In the embodiment, the condition for judging whether the road is unobstructed is specifically limited, and the method is simple and easy to implement and high in reliability.
FIG. 2 is a flow chart of a method of automatic cruise control according to yet another exemplary embodiment. As shown in fig. 2, on the basis of fig. 1, the method may further include the following steps.
Step S111: and acquiring the speed limit value of the road section where the vehicle is located.
Step S141: and judging whether the speed limit value of the road section where the vehicle is located is greater than a preset speed limit threshold value.
In this embodiment, if it is determined that the driver is tired, the road is clear, and the vehicle has a history of auto-cruise travel in the current road segment, the step of controlling the auto-cruise system to be turned on so that the vehicle automatically cruise travel (step S15) may include:
step S151: and if the driver is fatigue, the road is smooth, the vehicle has the history of automatic cruise driving in the current road section, and the speed limit value of the road section where the vehicle is located is greater than the preset speed limit threshold value, controlling to open an automatic cruise system so that the vehicle can automatically cruise and drive.
The speed limit value of the road section where the vehicle is located can be determined according to the electronic map after the vehicle positions the vehicle. If the speed limit value of the road section where the vehicle is located is larger than the preset speed limit threshold value, the vehicle is considered to be allowed to run at a higher speed in the current road section, and therefore the automatic cruise is started conveniently. The speed limit threshold may be obtained experimentally or empirically, and may be 120km/h, for example.
In the embodiment, the speed limit value of the road section where the vehicle is located is also used as a necessary condition for starting the automatic cruise, so that the feasibility and the safety of the current automatic cruise are further enhanced.
In yet another embodiment, after turning on the auto cruise system, the method may further comprise the steps of: acquiring a speed limit value of a road section where a vehicle is located; and adjusting the speed of the automatic cruise according to the acquired speed limit value.
During the automatic cruising of the vehicle, the vehicle may pass through the road sections with different speed limit values, and if the fixed vehicle speed in the automatic cruising exceeds the speed limit value of the road section where the vehicle is located, the fixed vehicle speed in the automatic cruising can be adjusted to be lower than or equal to the speed limit value of the road section where the vehicle is located. For example, the fixed vehicle speed in auto cruise may be 60km/h, which may be used if the speed limit value is 100km/h, or may be adjusted to, for example, 35km/h, if the vehicle travels to a new road section and the speed limit value is 40 km/h. When the vehicle continues to move to another road section with the speed limit value of 80km/h, the fixed speed in the automatic cruise can be adjusted to be 75 km/h. Therefore, the speed of the automatic cruise can change along with the speed limit value of the road section where the vehicle is located, danger caused by overspeed is avoided, and the driving safety of the vehicle is enhanced.
