Background
The driver mistakenly uses the accelerator as the brake in an emergency, which is one of causes of automobile traffic accidents. In order to solve the defect, a plurality of solutions for integrating the accelerator and the brake are disclosed in the prior art. For example, patent document CN2681939Y discloses an integrated accelerator and brake device. The device combines an accelerator control lever and a brake control lever with the same pedal, and the accelerator control lever is clamped on the pedal; when the pedal is at a zero position, the pedal is clamped and positioned by the locking device, and the vehicle is in an idling state; the pedal drives the accelerator control rod to move upwards when the pedal is loosened from the zero position by pushing the locking device with the foot, and the vehicle is refueled and accelerated; the brake control rod is pressed below the pedal, when the pedal is stepped down from a zero position, the pedal pushes the brake control rod to move downwards, and the vehicle is braked. When the device is used, different operations such as pushing away the locking device and stepping down are required to be carried out by feet, the requirement on the flexibility of the feet is high, and the use is inconvenient.
Disclosure of Invention
The invention aims to solve the technical problem of providing a brake-accelerator integrated device and a control method thereof, which can finish different operations of vehicle acceleration, deceleration, uniform speed running, braking and the like only by stepping on a pedal when in use.
In order to solve the technical problems, the invention adopts the following technical scheme:
in one aspect, the invention provides a brake and accelerator integrated device.
The brake and accelerator integrated device comprises a pedal, a control switch and a driving system. The area from the top to the bottom is divided into an intelligent speed reduction area, an oil feeding speed regulation area, a buffer transition area and a braking speed reduction area in sequence. The control switch is used for starting a brake and accelerator integrated mode of the pedal, and the pedal in the mode is automatically lifted through the buffer transition area.
The driving system is used for adopting the following control modes for the vehicle according to the position and the state of the pedal when the pedal is in a brake-accelerator integrated mode: 1) when the pedal is in a braking deceleration zone, the pedal is used as a conventional brake pedal; 2) when the pedal is in the buffer transition area, the driving system drives the vehicle at an idle speed; 3) when the pedal is positioned in the oil supply speed regulation area, the driving system regulates the driving speed of the vehicle, and the speed of the vehicle is continuously increased from the bottom to the top of the oil supply speed regulation area; if the stepping-down speed or the lifting speed of the pedal is higher than the normal speed, the driving system does not refuel the vehicle; 4) when the pedal is in the intelligent deceleration area, if the pedal enters the area for a period of time t1, the driving system does not refuel the vehicle. The no-refuelling is a state in which the automobile engine is operated at the lowest speed without the refueling door.
When the pedal is used as a conventional brake pedal, the vehicle can be decelerated through braking when being stepped down, and emergency braking can be realized when the pedal is stepped to the bottom. When the stepping-down speed or the lifting speed of the pedal in the oil feeding speed regulating area is in the range of normal speed, the foot is stepped on the pedal, so that the pedal is limited. If the pedal rebounds after being suddenly stepped down because the pedal is not put on the foot or the pedal rebounds because of an accident, the ascending speed is higher than the general normal speed, and the descending speed when the pedal is suddenly stepped down is also higher than the general normal speed. The normal speed of the stepping-down speed or the lifting-up speed can be collected and counted by a driving system, and can also be preset when leaving a factory.
The activity angle of the intelligent deceleration area is preferably 0.5-2 degrees; the moving angle of the oil feeding speed regulating area is preferably 10-30 degrees; the movement angle of the braking deceleration area is preferably 12-30 degrees; the active angle of the buffer transition zone is preferably 0.5-2 degrees. The intelligent deceleration zone and the buffer transition zone are mainly used for transition and buffer, so the angle is far smaller than the other two zones. The speed of the vehicle regulated by the traveling system preferably floats at a constant speed along with the change of the movable angle of the pedal in the oil supply speed regulation area. The vehicle speed is at a maximum when the pedal is raised to the top of the throttle area.
In addition, the device can also comprise an alarm device connected with a driving system, and the alarm device is used for sending different alarm signals when the brake and accelerator integrated mode is started and the pedal enters the intelligent deceleration zone t 1. The t1 time is preferably 0.5-3 s.
In addition, the device may also include an angular sensor. The angle sensor has a function of measuring an angle and an angular velocity, and is used for detecting a position and a velocity of the pedal and transmitting a detection result to the traveling system. The angle sensor can be connected between the pedal and the running system, or can be integrated in the pedal or the running system.
On the other hand, the invention also provides a control method for controlling the brake-accelerator integrated device.
The control method comprises the following steps:
1) a brake and accelerator integrated mode of a pedal is started through a control switch;
2) the pedal is pedaled, and the following operations are carried out according to the requirements of the vehicle:
2.1) when the running speed needs to be increased, lifting the pedal in the oil supply speed regulation area;
2.2) when the vehicle is required to run at a constant speed, the pedal is stopped in the oil supply speed regulation area;
2.3) when the running speed needs to be reduced, the pedal is stepped down in the oil supply speed regulation area;
2.4) when the speed reduction through the braking is needed, the pedal is stepped down to the braking speed reduction area.
Generally, when the vehicle needs to be braked emergently, the pedal is quickly stepped down to the bottom of a braking deceleration area.
The invention has the beneficial effects that:
1) after the pedal starts the brake-accelerator integrated mode, the switching of the pedal by feet can be effectively reduced, the situation that the accelerator is mistakenly stepped on as a brake is reduced, a driver can concentrate on driving more, and the driver is not easy to be distracted, so that the driving safety is improved; 2) when in use, the vehicle can finish different operations such as acceleration, deceleration, uniform speed running, braking and the like by only adopting the action of treading, and is convenient to use; 3) the pedal depth which can make the feet easier can be selected according to the human engineering, and the driver can easily realize the operations of uniform speed, free sliding and the like.
