Detailed Description
The following describes the safety control system of the vehicle according to the present invention with reference to the accompanying drawings.
Fig. 1 shows a schematic structural diagram of a vehicle active speed limit control system provided by the embodiment. The control system includes: the device comprises a steering wheel control button 1, a speed limit value acquisition module 2, a speed limit controller 5 and an engine 6.
The steering wheel control button 1 is used for selecting a function mode, the function mode comprises a normal driving mode and a speed limiting function mode, and the speed limiting function mode comprises a general speed limiting mode and a map speed limiting mode.
The speed limit value acquisition module 2 is used for acquiring a speed limit value.
The speed limit controller 5 comprises a speed sensor for acquiring a real-time speed value of the vehicle. And the speed limit controller 5 is used for sending a control instruction after comprehensive processing and calculation according to the functional mode selected by the steering wheel control button 1 and by combining the real-time vehicle speed value and the speed limit value so as to realize the automatic speed limit function of the vehicle. The engine 6 controls the vehicle operation based on the control instruction.
Wherein the speed limit controller 5 is configured to:
when the normal running mode selected by the steering wheel control button 1 is received, the speed limit controller 5 directly controls the vehicle to run normally. When the speed limit function mode is selected by the steering wheel control button 1 and the real-time vehicle speed value is not greater than the speed limit value, the speed limit controller 5 directly controls the vehicle to normally run. When the steering wheel control button 1 is received to select the speed limit function mode and the real-time vehicle speed value is greater than the speed limit value, the speed limit controller 5 autonomously controls the engine to reduce the fuel injection quantity and reduce the vehicle speed until the real-time vehicle speed is not greater than the speed limit value.
The vehicle active speed-limiting control system of the embodiment can autonomously select any one functional mode of a normal driving mode, a general speed-limiting mode and a map speed-limiting mode according to requirements, is flexible to select, can freely switch various control modes, and is convenient and fast; when the map speed limit mode is selected, the vehicle speed can be automatically limited not to exceed the speed limit value according to the speed limit value in the GPS navigation host 32, a driver does not need to adjust the vehicle speed independently, energy is saved, and violation or accident caused by overspeed is effectively reduced.
The system in this embodiment further comprises an accelerator pedal 4, an accelerator pedal sensor 41 and an overtaking switch 42. The accelerator pedal 4 is used to accelerate the vehicle so that the vehicle travels normally. The accelerator pedal sensor 41 is disposed on the accelerator pedal 4, and configured to acquire a stepping signal of the accelerator pedal 4. The overtaking switch 42 is arranged on the accelerator pedal 4 and is configured to enable the vehicle to directly enter the normal running mode after the overtaking switch 42 is triggered when the vehicle is in the speed-limiting function mode and needs to overtake temporarily, the speed-limiting function mode is suspended, and the vehicle is turned on again to enter the speed-limiting function mode by manually pressing the steering wheel control button 1 after the overtaking is finished. If some special or emergency situations are met during the driving process in the speed limiting function mode, a driver needs to overtake temporarily, but the situation can happen suddenly and is not as much as possible to switch the function mode manually. The present invention thus provides an overtaking switch 42 at the foot of the system pedal. When the overspeed switch 42 is turned on when the overspeed is required in the speed limit mode, the speed limit mode is temporarily stopped, the overspeed can be performed by stepping on the accelerator pedal 4, and after the overspeed is finished, the vehicle speed limit mode is selected by the steering wheel control button 1. The trouble caused by the fact that overspeed cannot be carried out in the speed limiting function mode is avoided, meanwhile, great convenience is brought to drivers, and the function mode does not need to be switched back and forth.
The speed limit value acquisition module comprises a GPS navigation host 32 and a speed setting module 31, wherein the GPS navigation host 32 is used for acquiring a first speed limit value in a navigation map in real time when the vehicle is in a map speed limit mode. The speed setting module 31 is used for manually setting a second speed limit value when the vehicle is in a general speed limit mode. When the vehicle is in the general speed limit mode and the map speed limit mode, the speed limit value acquisition modes are different, so different speed limit values need to be acquired in different modes. When the vehicle is in the map speed limit mode, the speed limit value does not need to be input, and the system directly obtains the speed limit value from the GPS navigation host. The existing vehicle or mobile phone generally comprises a GPS navigator, so that the first speed limit value can be acquired very conveniently and updated in real time without manual change.
The system in the embodiment also comprises a combination meter 7 which displays the real-time vehicle speed and the speed limit value in real time and sends out flashing display. The flashing display is performed when the real-time speed of the vehicle is greater than the speed limit value in the speed limit function state. Of course, the flashing display is only a prompt to warn the owner that the driving state of the vehicle needs to be adjusted. As other embodiments, the alarm and the vibration reminding can be replaced, or the combination of the three or the coexistence of the three can be realized. And reasonable selection is carried out according to the actual needs and cost.
The system also comprises a speed increasing and decreasing setting key, which is used for increasing or decreasing the second speed limit value of the vehicle in the general speed limit mode by pressing the key, and is configured that when the duration of pressing the key is less than 1s, the key is stepped by 1 KM/time, and when the duration of pressing the key is more than 1s, the key is stepped by 5 KM/time. Because a speed limit value, namely a second speed limit value, needs to be set in a general speed limit state, the second speed limit value needs to be manually input into the system, and the size of the second speed limit value can be adjusted according to actual needs, the speed increase and decrease setting key is arranged in the system, the size of the second speed limit value can be adjusted by pressing the speed increase and decrease setting key, and therefore the second speed limit value can be flexibly limited, and the speed limit control system is convenient and quick.
As an embodiment, the speed limit controller 5 of the present system includes: an engine control module 51 and a speed limit function module 52. The engine control module 51 is configured to send a control signal to the engine 6 to control the operation of the engine 6, wherein the speed sensor is integrated in the engine control module 51. The speed limit function module 52 is configured to receive signals from the speed limit value obtaining module 2, the accelerator pedal sensor 41, the overtaking switch 42, and the speed sensor, process and calculate the signals, and output signals to the engine control module 51 to further send the control instruction to control the engine 6 to operate.
As a specific implementation manner, the speed limit function module 52 includes: an input unit 521, a signal acquisition unit 522, a central processing unit 523, a human-computer interaction unit 525 and a signal output unit 524. The input unit 521 is used for receiving the speed limiting function status information sent from the steering wheel control button 1 and transmitting the speed limiting function status information to the central processing unit 523. The signal acquisition unit 522 is configured to receive signals from the speed limit value acquisition module 2, the accelerator pedal sensor 41, and the overtaking switch 42, and transmit the signals to the central processing unit 523. The central processing unit 523 is configured to receive signals from the input unit 521 and the signal acquisition unit 522, process and calculate the signals, and then send the signals. The human-computer interaction unit 525 is used for operating through the vehicle speed and speed limit signals displayed by the combination meter 7 and outputting the signals to the central processing unit 523. The signal output unit 524 is configured to receive the signal from the central processing unit 523 and output the signal to the engine control module 51.
When the system is in a normal running mode, the speed-limiting controller 5 has no speed-limiting control function on the engine 6, only receives a signal from the accelerator pedal 4 and then directly transmits the signal to the engine 6, so that the engine 6 accelerates or decelerates the vehicle along with the signal of the accelerator pedal 4. When the vehicle starts a general speed limit mode, the speed limit controller 5 receives a second speed limit value from the speed setting module 31, compares the magnitude of the real-time vehicle speed and the second speed limit value, if the real-time vehicle speed is greater than the second speed limit value, the speed limit controller 5 sends an instruction to the engine control module 51, and controls the engine 6 to reduce the fuel injection amount until the real-time vehicle speed is not greater than the second speed limit value, and the accelerator pedal 4 directly controls the acceleration and deceleration of the vehicle. When the vehicle starts a map speed limit mode, the speed limit controller 5 receives a first speed limit value from the GPS navigation host machine 2, compares the magnitude of the real-time vehicle speed and the first speed limit value, if the real-time vehicle speed is greater than the first speed limit value, the speed limit controller 5 sends an instruction to the engine control module 51, and controls the engine 6 to reduce the fuel injection quantity until the real-time vehicle speed is not greater than the first speed limit value, and the accelerator pedal 4 directly controls the acceleration and deceleration of the vehicle. The speed limit controller 5 is very sensitive in control and can accurately control the speed of the vehicle in different modes. The mode that the speed limit controller 5 controls the oil injection quantity of the engine 6 is as follows: and controlling the opening of a throttle valve in front of the engine, and reducing the opening of the throttle valve when the vehicle is in a speed limiting function mode and the real-time vehicle speed is greater than a speed limit value (a first speed limit value or a second speed limit value) so as to reduce the fuel injection quantity to decelerate the vehicle when the vehicle needs to decelerate.
In some special cases, the speed limit controller 5 may also be configured to: when the real-time speed of the vehicle entering the general speed limiting mode or the map speed limiting mode from the normal running mode is larger than the speed limiting value through the steering wheel control button 1, the vehicle does not immediately enter the general speed limiting mode or the map speed limiting mode until the vehicle speed is smaller than the speed limiting value, and the vehicle automatically enters the speed limiting mode. When a driver suddenly switches the vehicle from a normal running mode to a speed limit mode (including a general speed limit mode and a map speed limit mode), if the real-time vehicle speed is higher than the speed limit value at the moment, the vehicle is inevitably decelerated suddenly if the driver directly enters the speed limit mode, and if the vehicle speed is very high, the vehicle is easy to cause danger due to sudden deceleration. The configuration mode can greatly reduce the occurrence rate of dangerous accidents.
FIG. 2 shows a flow chart of steps of a method for active speed limit control of a vehicle.
As shown in fig. 2, the active speed limit control method for a vehicle of the present invention includes the following steps:
s10, manually selecting functional modes, wherein the functional modes comprise a normal driving mode and a speed limiting functional mode, and the speed limiting functional mode comprises a general speed limiting mode and a map speed limiting mode;
s20, sensing real-time vehicle speed and speed limit value;
s30, based on the functional mode and the comparison between the real-time vehicle speed and the speed limit value, judging whether to send a speed limit instruction; when the vehicle is in a speed limiting function mode and the real-time vehicle speed value is greater than the speed limiting value, sending a speed limiting instruction, otherwise, not sending the speed limiting instruction;
and S40, automatically limiting the vehicle speed based on the speed limit command.
When the speed limit instruction is not sent out, the vehicle directly controls an engine 6 (see figure 1) to drive according to an accelerator pedal 4 (see figure 1). The speed limit value of the general speed limit mode is manually set. The speed limit value of the map speed limit mode is directly from the speed limit value in the GPS navigation host machine 2 (see figure 1).
The speed limit instruction is not issued, and (1) the vehicle is in a normal running mode. Or (2) the vehicle is in a general speed limit mode, and the real-time vehicle speed is not greater than the manually set speed limit value in the general speed limit mode; or (3) the vehicle is in a map speed limit mode, and the real-time speed is not greater than the limited speed limit value in the vehicle-mounted GPS navigation host machine 2. When no instruction is given, the vehicle runs normally, and the driver steps on the accelerator pedal 4 to control the speed of the vehicle.
Fig. 3 is a control logic diagram of a workflow provided by an embodiment of the method of the present invention. As shown in FIG. 3, the workflow control logic of the vehicle active speed limit control system is as follows: after the engine 6 (see figure 1) is ignited, the system is self-checked, and if no system fault exists, the system enters the active speed limit control system. And manually selecting a function mode, selecting whether to enter a speed limit function mode, and if not, driving an engine 6 to control the vehicle to normally run by an accelerator pedal 4 (see figure 1). When the speed limit function mode is selected, two speed limit function modes of a general speed limit mode and a map speed limit mode can be provided. If the general speed limit mode is selected, a second speed limit value is manually input. And the speed limit controller 5 compares the real-time vehicle speed with a second speed limit value manually input, and at the moment, if the real-time vehicle speed is greater than the second speed limit value, the vehicle is limited in speed, otherwise, the vehicle enters a normal driving mode. If the map speed limit mode is selected, the real-time vehicle speed is compared with the first speed limit value in the GPS navigation host machine 2 (see FIG. 1). And at the moment, if the real-time speed is greater than the first speed limit value, limiting the speed of the vehicle, otherwise, entering a normal driving mode. Of course, after the speed limit, when the real-time vehicle speed is greater than the speed limit value, the speed limit state is continued until the real-time vehicle speed is not greater than the speed limit value.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
