Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
The embodiment of the invention provides an acceleration control method, which is applied to an intelligent vehicle, wherein the intelligent vehicle comprises the following steps: a brake pedal at the right foot and a pressure sensor at the steering wheel handle connected to an acceleration module, the acceleration pedal at the right foot being eliminated, as shown in fig. 1, a pressure sensor is provided at the steering wheel handle, the pressure sensor being connected to an acceleration module for controlling the acceleration of the vehicle.
As shown in fig. 2, the acceleration control method includes:
s201, after the intelligent vehicle is started, controlling the intelligent vehicle to run at a safe speed;
s202, detecting whether the pressure value of pressure operation at the handle of the steering wheel exceeds a preset pressure or not;
and S203, if not, controlling the intelligent vehicle to accelerate on the basis of the safe speed based on the pressure operation.
First, the smart vehicle can implement a portion of automatic control functions, for example, it can drive at a certain driving speed, and the driver only needs to control emergency and special situations.
Therefore, the smart vehicle has a function of acquiring a safe speed, which is determined based on the vehicle information and the surrounding environment information.
Specifically, performance parameters of the intelligent vehicle, a road running condition, a traffic flow condition and a weather condition are obtained. The performance parameters of the vehicle include: the number of passengers carried by the vehicle, the maintenance mileage, the self-weight condition of the vehicle, the braking performance of the vehicle and the like. The road driving condition is specifically whether the position is on an express way of the city, or at a high speed, or passes through a pedestrian area, the road quality, the road curvature degree, the road icing risk and the like. The traffic conditions are specifically the number of lanes and the density of the traffic. The light intensity is determined according to weather conditions, such as foggy weather, day or night, and the like.
And determining the safe speed of the intelligent vehicle based on the performance parameters of the intelligent vehicle, the road running condition, the traffic flow condition and the weather condition.
The method for determining the safe speed of the intelligent vehicle according to the performance parameters of the intelligent vehicle, the road running condition, the traffic flow condition and the weather condition can be obtained through a complex algorithm.
The safe speeds corresponding to the express way, the expressway and the pedestrian area are different, and for different weathers on different roads, such as foggy weather, the safe speed is relatively low, the safe speed is also relatively low at night, and the safe speed is normal at day, which is not described in detail herein.
And after the safe speed of the intelligent vehicle is obtained, controlling the intelligent vehicle to run according to the safe speed.
During the running, S102 is executed to detect whether the pressure value of the pressure operation at the handle of the steering wheel exceeds a preset pressure.
In the step, on one hand, whether pressure data are collected at the handles at the two sides of the steering wheel is detected, and if yes, pressure operation is determined at the handles at the two sides of the steering wheel. The wrong operation that some drivers do not hold the steering wheel or hold the steering wheel by one hand when driving is avoided by confirming that the handles on the two sides of the steering wheel are all operated by pressure. On the other hand, when pressure operation is confirmed on handles on two sides of the steering wheel, whether the pressure value of the pressure operation exceeds the preset pressure or not is judged, acceleration is needed only when the pressure value exceeds the preset pressure, and acceleration is not needed when the pressure value does not exceed the preset pressure.
Therefore, when the preset pressure is exceeded, S103 is executed, based on which the smart vehicle is controlled to accelerate on the basis of the safe speed.
In an alternative embodiment, based on the pressure operation, the intelligent vehicle is controlled to accelerate on the basis of the safe speed according to the pressure value of the pressure operation and the speed of the intelligent vehicle in a proportional relation.
For example, a pressure value of 5 corresponds to a vehicle speed of 30, a pressure value of 6 corresponds to a vehicle speed of 36, and so on, with a scaling factor of 6.
Of course, the pressure value of the pressure operation may be in an exponential relationship with the speed of the intelligent vehicle, as long as the speed after the acceleration control is increased along with the increase of the pressure, and the method is not limited herein.
After accelerating the speed of the intelligent vehicle, the method further comprises the following steps: acquiring a first accelerated speed; when the pressure value of the pressure operation at the handle of the steering wheel is detected to be smaller than the preset pressure value, the intelligent vehicle is controlled to decelerate to the safe speed according to the first preset acceleration on the basis of the first speed.
The intelligent vehicle accelerates to deal with special conditions, and after the special conditions are finished, the vehicle speed needs to be restored to a normal vehicle speed, namely a safe speed. When the pressure operation at the handle of the steering wheel is detected to be smaller than the preset pressure value, the acceleration ending can be determined, and the acceleration ending means that the speed can be reduced according to the preset acceleration, so that the speed is restored to the safe speed.
The intelligent vehicle not only needs to accelerate from the safe speed and then recover to the safe speed in the driving process, but also needs to decelerate from the safe speed and then recover to the safe speed.
The following describes the deceleration of the vehicle from the safe speed and the return to the safe speed.
After S101, namely after acquiring the safe speed, when the driver needs to decelerate, such as an emergency situation occurs and deceleration is needed, whether the intelligent pedal is subjected to stepping operation is detected, if so, the intelligent vehicle is controlled to decelerate on the basis of the safe speed, and the brake lamp is controlled to be turned on in the process of deceleration.
In a specific embodiment, the intelligent vehicle is controlled to decelerate on the basis of the safe speed, and the relation between the trampling force and the deceleration intensity is controlled according to the brake pedal. The brake lamp is turned on during depression of the brake pedal, so that the rear vehicle can determine that the front vehicle is decelerating.
After decelerating, the method further comprises the following steps:
acquiring a decelerated second speed; and when the situation that the brake pedal is not stepped is detected, controlling the intelligent vehicle to accelerate to the safe speed according to a second preset acceleration on the basis of a second speed.
Since the force with which the brake pedal is stepped on is different according to the driving habits of different drivers, the second speed after deceleration is also different, and the time is also different when returning to the safe speed from the different second speed.
Wherein, can restore to safe speed according to the predetermined acceleration of second, this predetermined acceleration of second can set up according to the habit of difference, when the user needs to restore fast to safe speed, can select the acceleration of great value, when need not to restore fast to safe speed, can select the acceleration of less value. And are not limited thereto.
Most importantly, the invention can separate acceleration control from deceleration control, wherein the acceleration control is controlled by the holding pressure of the steering wheel, and the deceleration control is controlled by the treading of feet, thus avoiding the problem that the acceleration control and the deceleration control are controlled by feet in the prior art and are easy to cause control errors, and further reducing the accident rate caused by the acceleration control errors by separate control of hands and feet.
