Detailed Description
The embodiment of the application solves the technical problem of lower safety of an automatic start-stop function in the prior art by providing the vehicle start-stop control method.
The technical scheme of the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:
a vehicle start-stop control method, the method comprising: monitoring the actual braking depth and the actual running speed of the target vehicle in the running process; when the actual braking depth is larger than a braking depth threshold value and the actual running speed is smaller than a first speed threshold value, monitoring the enabling state of the automatic start-stop function of the target vehicle; monitoring a running environment parameter of the target vehicle when the enabling state is closed; determining a corresponding estimated safety coefficient of the target vehicle after the automatic start-stop function is started according to the running environment parameters; and when the estimated safety coefficient is larger than the safety coefficient threshold value, controlling the enabling state to be switched to be on.
According to the method, the device and the system, the actual braking depth and the actual running speed are monitored in the running process of the target vehicle, whether the driver of the target vehicle has a parking intention is determined, if the driver of the target vehicle has the parking intention, whether the automatic start-stop function is in a closed state is determined, if the driver of the target vehicle has the parking intention, the estimated safety coefficient of the automatic start-stop function is determined by combining the current running environment parameters of the target vehicle in the closed state, when the estimated safety coefficient is larger than the safety coefficient threshold, the control enabling state is converted into the on state, and then the target vehicle can use the automatic start-stop function on the premise of ensuring safety, so that the safety of the target vehicle using the automatic start-stop function is improved, and the probability of safety accidents of the target vehicle due to the automatic start-stop function is reduced.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
First, the term "and/or" appearing herein is merely an association relationship describing associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
The embodiment provides a vehicle start-stop control method as shown in fig. 1, which includes steps S11-S15. The vehicle start-stop control method provided in the embodiment may be executed by a controller of a target vehicle or may be executed by a cloud server.
Step S11, monitoring the actual braking depth and the actual running speed of the target vehicle in the running process;
step S12, when the actual braking depth is larger than a braking depth threshold value and the actual running speed is smaller than a first speed threshold value, monitoring the enabling state of the automatic start-stop function of the target vehicle;
step S13, when the enabling state is closed, monitoring the running environment parameters of the target vehicle;
step S14, determining a corresponding estimated safety coefficient of the target vehicle after the automatic start-stop function is started according to the running environment parameters;
and S15, when the estimated safety coefficient is greater than the safety coefficient threshold value, the control enabling state is switched to be on.
With respect to step S11, the actual braking depth and the actual running speed of the target vehicle during running are monitored.
The target vehicle may be any vehicle having an automatic start-stop function. The target vehicle is in a state in which the target vehicle has a running speed other than 0 during running. The actual braking depth refers to the depth to which the brake pedal of the target vehicle is depressed, and the actual running speed refers to the running speed of the target vehicle along the road.
And monitoring the actual braking depth and the actual running speed of the target vehicle according to the preset acquisition frequency when the target vehicle is in running. Wherein the preset frequency may be determined based on a rate of change of speed of the target vehicle. For example, when the speed change rate of the target vehicle (such as the change rate between adjacent speeds per second) exceeds the change threshold, meaning that the driver has a driving intention of rapid acceleration or rapid deceleration, the actual braking depth and the actual running speed may be monitored with a higher preset frequency, for example, collected every 0.1 seconds. When the speed change rate of the target vehicle does not exceed the change threshold, meaning that the driver is driving relatively smoothly, the actual braking depth and the actual running speed may be monitored with a lower preset frequency, for example, collected every 0.5 seconds.
After the actual braking depth and the actual running speed of the target vehicle are monitored according to the acquisition frequency, the magnitude relation between the actual braking depth and the braking depth threshold value is compared, and the magnitude relation between the actual running speed and the first speed threshold value is compared. The braking depth threshold value and the first speed threshold value can be set according to actual conditions.
When the actual braking depth is smaller than the braking depth threshold value or the actual running speed is larger than the first speed threshold value, it means that the driver does not have the parking intention, and the automatic start-stop function is not used with a high probability, so the process can continue to step S11 to continuously monitor the actual braking depth and the actual running speed of the target vehicle, and compare the magnitude relation between the actual braking depth and the braking depth threshold value and the magnitude relation between the actual running speed and the first speed threshold value to judge whether the driver has the parking intention.
When the actual braking depth is greater than the braking depth threshold value and the actual running speed is less than the first speed threshold value, which means that the driver has a intention to park, step S12 may be continued to be performed.
With respect to step S12, when the actual braking depth is greater than the braking depth threshold value and the actual running speed is less than the first speed threshold value, the enabled state of the automatic start-stop function of the target vehicle is monitored.
The enabling states of the automatic start-stop function include an on state and an off state. When the enabling state is in the on state, the automatic start-stop function is in the enabling state, and when the target vehicle meets the automatic start-stop condition, the target vehicle can realize automatic start-stop. When the enabling state is in a closed state, the automatic start-stop function is in a closed state, and the target vehicle cannot realize automatic start-stop no matter whether the target vehicle meets the automatic start-stop condition or not. The enable state of the automatic start-stop function may be represented by a flag bit, for example, when the flag bit of the enable state is 1, the enable state is turned on, and when the flag bit is 0, the enable state is turned off.
When the actual braking depth is greater than the braking depth threshold and the actual running speed is less than the first speed threshold, which means that the driver has a parking intention, the automatic start-stop function may be used, and at this time, the enabled state of the automatic start-stop function of the target vehicle may be monitored, that is, whether the automatic start-stop function of the target vehicle is in an on state may be determined. When the enabling state is on, the corresponding steps from step S21 to step S28 may be executed, and the automatic start-stop of the vehicle may be implemented in response to the related instruction of the automatic start-stop function. When the enabling state is off, step S13 is continuously executed to determine whether the target vehicle is currently capable of starting the automatic start-stop function, i.e. whether the target vehicle meets the condition of starting the automatic start-stop function.
With respect to step S13, when the enabled state is off, the running environment parameter of the target vehicle is monitored.
When the enabled state is off, the running environment parameter of the target vehicle is monitored. The driving environment parameters include, but are not limited to, a climate environment including, but not limited to, an atmospheric pressure, an atmospheric temperature, weather (including rainy, snowy, foggy, sunny, thunderstorm, etc.), brightness (including daytime, night, evening, dusk, etc.), and a road environment including, but not limited to, an uphill slope, a downhill slope, a curve, a traffic line (such as a sidewalk, a double solid line, a single solid line, etc.), traffic equipment (traffic lights, barrier fences, road signs, etc.).
The monitoring mode of the running environment parameters comprises but is not limited to networking, map, navigation, vehicle-mounted camera, vehicle-mounted radar, infrared sensing equipment and the like.
For example, the target vehicle gradually decelerates under the premise that a driver has a parking wish, the climate environment of the position of the target vehicle can be determined through networking or a vehicle-mounted camera, and the road environment of the target vehicle can be determined according to a map, navigation, the vehicle-mounted camera, a vehicle-mounted radar and an infrared sensing device.
Regarding step S14, the estimated safety coefficient corresponding to the target vehicle after the automatic start-stop function is activated is determined according to the driving environment parameters.
And determining the corresponding estimated safety coefficient of the target vehicle after the automatic start-stop function is started according to the running environment parameters and the corresponding relation between the running environment and the safety coefficient. Namely, inquiring the corresponding relation between the running environment and the safety coefficient according to the running environment parameters, and further determining the corresponding estimated safety coefficient.
The correspondence between the running environment and the safety coefficient may be determined in advance according to a related test process, a simulation process, or a data estimation process.
The correspondence between the running environment and the safety coefficient will now be described by way of example. For example, a certain driving environment is that the left side of the target vehicle is a segregator fence, the front side is a sidewalk, the right side is a solid line, the traffic light is a red light, and the road has no gradient, which means that the target vehicle is at a road lamp intersection and needs to be stopped for waiting, the possibility of sliding the target vehicle after the engine of the target vehicle is stopped is smaller, and at the moment, the corresponding safety coefficient is higher after the automatic start-stop function is started, and the corresponding safety coefficient is 80%.
For another example, a certain driving environment is that the left side of the target vehicle is a barrier fence, the front side is a sidewalk, the right side is a solid line, the traffic light is a red light, and the current road section is an uphill road section, which means that the target vehicle is at a road lamp intersection and needs to stop for waiting, the possibility that the target vehicle slides on a ramp after the engine is stopped is high, and the corresponding safety coefficient is low and corresponds to 20% after the automatic start-stop function is started.
After the estimated safety coefficient is obtained, the magnitude between the estimated safety coefficient and the safety coefficient threshold value can be compared, when the estimated safety coefficient is smaller than the safety coefficient threshold value, the safety coefficient which is used for starting the automatic start-stop function at present is lower, the enabling state can be controlled to be kept closed, the automatic start-stop function is avoided, and then potential safety hazards caused by the automatic start-stop function are avoided. When the estimated safety factor is greater than the safety factor threshold, it means that the safety factor of the automatic start-stop function is higher, and step S15 may be continuously performed.
The safety coefficient threshold value can be determined according to the safety requirement precision and the fuel saving requirement of the target vehicle. When the safety requirement precision is higher and the oil saving requirement is less important, a larger safety coefficient threshold value can be selected. When the safety requirement is less accurate and the fuel saving requirement is more important, a relatively smaller safety factor threshold can be selected. When the safety demand accuracy and the fuel saving demand are relatively balanced, a moderate safety coefficient threshold may be selected.
Regarding step S15, when the estimated safety factor is greater than the safety factor threshold, the control enable state is switched to on.
When the estimated safety coefficient is larger than the safety coefficient threshold, the safety coefficient of the automatic start-stop function is higher, the enabled state can be controlled to be converted into the on state, so that a protection mechanism can be added for the use safety of the automatic start-stop function, the automatic start-stop function can be started only in the safety state, and after the automatic start-stop function is started, the steps S21-S28 can be continuously executed, so that the safety of the target vehicle in using the automatic start-stop function is further improved.
In summary, the present embodiment monitors the actual braking depth and the actual driving speed during the driving process of the target vehicle, determines whether the driver of the target vehicle has a parking intention, if so, determines whether the automatic start-stop function is in a closed state, if so, determines the estimated safety coefficient of the target vehicle using the automatic start-stop function by combining the current driving environment parameters of the target vehicle, and when the estimated safety coefficient is greater than the safety coefficient threshold, the control enabling state is switched to be on, so that the target vehicle can use the automatic start-stop function under the premise of ensuring the safety, the safety of the target vehicle using the automatic start-stop function is improved, and the probability of the target vehicle having a safety accident due to the automatic start-stop function is reduced.
On the basis of the above scheme, the embodiment also provides a start-stop control method of the target vehicle when the enabling state is on, specifically comprising the steps of S21-S23, and the method is applied to the stopping process of the target vehicle; step S24-step S26 are also included, and the starting process is applied to the target vehicle; further includes steps S27-S28, applied to the running process of the target vehicle.
[ parking Process ]
Step S21, monitoring whether the actual running speed of the target vehicle is 0;
step S22, when the actual running speed is 0, monitoring whether the duration time of the actual running speed of 0 exceeds a first preset duration time;
in step S23, when the duration of the actual running speed is 0 exceeds the first preset duration, the engine stop of the target vehicle is controlled in response to the engine stop command corresponding to the automatic start-stop function of the target vehicle.
The actual running speed of the target vehicle is monitored as to whether or not it is 0, and the object is to monitor whether or not the target vehicle is in a stopped state. When the actual running speed is 0, it means that the target vehicle is in a stopped state, and it is necessary to continuously determine whether the target vehicle is stopped briefly or not, that is, continuously monitor whether the duration of time when the actual running speed is 0 exceeds the first preset duration.
When the duration time does not exceed the first preset duration time, the target vehicle can continue to run, at the moment, if the driving component of the target vehicle is damaged when the engine stop is controlled, the running sensitivity of the target vehicle can be reduced, and potential safety hazards such as rear-end collision exist, at the moment, even if the automatic start-stop function generates a corresponding engine stop instruction, the engine stop of the target vehicle can not be controlled, and the running safety and the running sensitivity of the target vehicle can be further ensured.
When the duration exceeds the first preset duration, the target vehicle can be stopped for a relatively long time, at the moment, the automatic start-stop function can automatically generate a corresponding engine stop instruction, and based on the engine stop instruction, the engine stop of the target vehicle is controlled, so that the safety of the target vehicle in using the automatic start-stop function can be further ensured to be higher, and the probability of safety accidents of the target vehicle due to the automatic start-stop function is reduced.
[ Start-up procedure ]
Step S24, monitoring whether an engine of a target vehicle is in a stop state;
step S25, when the engine of the target vehicle is in a stop state, monitoring the actual throttle depth of the target vehicle;
and step S26, when the actual accelerator depth is larger than the accelerator depth threshold, controlling the engine of the target vehicle to start in response to an engine start command corresponding to the automatic start-stop function of the target vehicle.
And monitoring whether the engine is in a stop state, if so, the actual accelerator depth of the target vehicle is monitored, if so, the target vehicle possibly needs to be started at any time, and when the actual accelerator depth is larger than an accelerator depth threshold value, the driver has the intention of restarting driving, the automatic start-stop function can generate a corresponding engine starting instruction, and the engine of the target vehicle is controlled to be started in response to the engine starting instruction. The throttle depth threshold value can be a smaller value so as to ensure the starting sensitivity of the engine, ensure that the target vehicle has higher driving efficiency and ensure that the driving experience of drivers and passengers is better.
[ running Process ]
Step S27, monitoring the actual accelerator depth and the actual running speed of the target vehicle;
in step S28, when the actual accelerator depth is greater than the first depth threshold and the actual running speed is greater than the second speed threshold, the control enabling state is switched to off.
When the actual accelerator depth is greater than the first depth threshold and the actual running speed is greater than the second speed threshold, the driver has driving intention of accelerating running, and if the automatic start-stop function is always in an on state, the possibility of safety accidents of the vehicle caused by the automatic start-stop function errors exists, so that the enabling state can be controlled to be switched to an off state, and the possibility of the safety accidents of the vehicle caused by the automatic start-stop function errors of the target vehicle is reduced.
In summary, in the embodiment, when the automatic start-stop function is in the on state, whether the target vehicle needs to respond to the start instruction or the stop instruction of the automatic start-stop function is determined by monitoring the running state of the target vehicle, so that the target vehicle is ensured to use the automatic start-stop function on the premise of safe running, and the safety of using the automatic start-stop function by the target vehicle is improved.
In addition, in the running process of the scheme, the technical schemes provided in the steps S31-S33 can be run in parallel, so that the target vehicle is further ensured to use the automatic start-stop function on the premise of safe running.
Step S31, monitoring the running state parameters of the target vehicle;
step S32, judging whether the running state parameters meet preset safety conditions or not;
in step S33, when the running state parameter does not satisfy the preset safety condition, the control enable state is kept off.
