Description

Vehicle brake consumption oil quantity prompting method and system thereof

The invention relates to a method and a system for prompting oil consumption of a brake of a vehicle, in particular to a method and a system for converting a sliding distance loss caused by a brake of a vehicle into a lossy oil quantity and outputting.

Environmental protection and energy conservation is the current mainstream consciousness in the world, and how to reduce automobile fuel consumption is the key research direction. Among the many fuel consumption reduction schemes, how to improve the driver's driving habits through new technologies, thereby reducing unnecessary fuel consumption and achieving energy-saving driving has become a key research project.

Nowadays, electronic equipment has begun to be widely used in the automotive industry. Through various sensors and powerful ECUs, it is possible to instantly capture/calculate various data of the vehicle's driving and provide it to the driver for reference. While the vehicle is running, there is no combination of acceleration, taxiing and braking. It is well known that the driver's throttle acceleration habit will affect fuel consumption. Therefore, the vehicle is also equipped with instantaneous fuel consumption and average fuel consumption data.

In addition, there are patents for calculating the fuel consumption value of the vehicle under different driving conditions, including individual fuel consumption statistics for acceleration, braking, turning, and ups and downs (CN104111095A), or intelligent analysis of fuel consumption of the vehicle (CN103884396A), with a view to further It shows the accurate fuel consumption value of the car under different driving conditions. Through current technologies and methods, drivers can be informed of fuel consumption data during driving and understand the impact of driving behavior on fuel consumption.

In fact, it is not enough to accurately display the fuel consumption value from the purpose of improving the driver's driving habits. Because of the hidden factor affecting the total fuel consumption, the "brake consumption" is not highlighted. Stepping on the accelerator to accelerate the driving is to do useful work for the advancement, but the brakes will consume the accelerated kinetic energy. If you want to advance after the brakes, you must re-fuel, so that the oil consumption will be repeated. This is the amount of oil consumed by the brakes.

As seen from Fig. 1 and Fig. 2, Fig. 1 shows the case where the brake is not used, and Fig. 2 shows the case where the brake is used, and the above two cases are explained from the A to the B, and the ideal is not used. The difference in oil usage between the brakes and the normal use of the brakes. For a fair comparison, assume that the throttle force used in both cases is exactly the same as the driving speed; as can be seen from Figure 1, the amount of oil added (assuming 0.5L) in the absence of brakes has caused the vehicle to be A. Move to place B;

However, in the case of the same throttle force and driving speed, the brakes consume the kinetic energy of the vehicle and reduce the sliding distance. Therefore, the same amount of oil can be used but the B cannot be reached, so additional oil must be required to reach the B ground. The extra oil in this part is regarded as the amount of oil consumed by the brakes, that is, the amount of oil used in comparison with the ideal condition (without braking).

Of course, the actual driving process must be accompanied by the braking behavior, but each driver has different driving habits and different ways of using the brakes. Therefore, there are also many unnecessary braking phenomena. In addition to wasting oil, these unnecessary brakes are also one of the main reasons that directly affect the safety of driving.

In order to improve driving habits and reduce fuel consumption while improving driving safety, in addition to passive display of the fuel consumption value of the driving state, the hidden fuel loss caused by the brakes should be further estimated. If there is such a data index for reference, it is possible for the driver to change the driving habits and minimize the unnecessary braking behavior to reduce the fuel consumption loss. At present, this part of the hidden oil consumption caused by the brakes, there is no relevant system to be presented on the market.

Therefore, it is possible to calculate and display the portion of the slip distance caused by the brake to be converted into the value of the consumed oil. The purpose is to compensate the driver by minimizing the amount of oil to minimize unnecessary braking behavior, to reduce unnecessary braking, and to improve fuel economy while improving driving safety, so the present invention should be an optimal solution.

The first object of the present invention relates to a method for prompting the amount of oil consumption of a brake of a vehicle, which is calculated and displayed based on the loss of the sliding distance caused by the brake and converted into a value of the consumed oil. By quantifying the amount of brake wear and oil, the driver is encouraged to minimize the unnecessary braking behavior, improve the ability of "predictable driving", predict the road conditions and traffic conditions at any time, and rationally control the throttle to save fuel consumption and improve driving safety. Sex.

Other details, features, and advantages of the present invention will be apparent from the following description of the preferred embodiments.

Please refer to FIG. 3 , which is a schematic flow chart of a method for prompting the fuel consumption of a vehicle brake and a system thereof. The flow chart is as follows: (1) Obtaining the initial braking speed of the vehicle, terminating the braking speed, and the braking period. The moving distance of the inner vehicle is 301; (2) obtaining the sliding distance 302 corresponding to the initial braking speed and the ending braking speed; (3) the sliding distance corresponding to the initial braking speed and the ending braking speed respectively Calculating the single brake damper loss distance 303 during the braking period; (4) calculating the single brake wear loss according to the average integrated fuel consumption of the vehicle, the average gliding state fuel consumption, and the single brake gliding loss distance The amount of oil is 304.

The above steps are the most basic processes of the present invention, but the actual implementation of the present invention can have the following six steps, wherein the first step (S1) is to obtain the starting brake speed of the vehicle, the ending braking speed, and the movement of the vehicle during the braking period. The distance, in which the starting brake speed is expressed as the current speed of the driver pressing the brake pedal under normal driving. There are two cases of terminating the brake speed: (a) for the driver to fully release the current speed of the brake pedal; (b) when the vehicle is under braking, the speed drops to zero (ie, the vehicle stops). The brake cycle means the time from the start of the brake to the end of the brake action.

In the second step (S2), the sliding distance corresponding to the starting brake and the ending braking speed of the vehicle are respectively acquired. Each vehicle speed has its corresponding taxiing distance. This part of the vehicle enterprise can perform the sliding test according to the national standard of taxiing test to obtain data and record. If there is no actual experimental data, the calculation method can also be used to estimate the sliding distance at each speed and record. The following is a specific calculation formula for calculating the sliding distance under the consideration of air resistance and rolling resistance: ................... (Formula 1) where H: the vehicle's gliding distance from the initial speed to zero speed (in m) M : Vehicle mass (unit KG) Cd : Vehicle drag coefficient a : Vehicle windward side Projection area (unit: m ² ) ρ : air density (generally 1.2258KG/m ³ ) V ₀ : initial vehicle gliding speed (unit: m / Sec) f : rolling resistance coefficient g : gravity acceleration, take 9.8m / Sec ²

At present, the industry and academia have different derivation formulas for calculating vehicle sliding distance and different consideration factors and environment. The above formula is an example of the calculation formula of the rolling resistance and air resistance of the tire and the asphalt road. When the present invention is practiced in practice, the calculation of the sliding distance can be performed using a suitable formula due to its own considerations.

In the third step (S3), the single brake coasting loss distance is calculated in order to combine the sliding distance corresponding to the initial braking/ending braking speed and the vehicle moving distance in the braking cycle. The so-called single brake coasting loss distance means the distance that the sliding distance is reduced due to the speed drop caused by the brake during one braking cycle. The specific calculation formula is as follows: SBLD = SSD – ESD – MD ................... (Formula 2) where SBLD is the single brake slip loss distance (m) SSD is the initial brake speed corresponding to The sliding distance (m) ESD is the sliding distance (m) corresponding to the ending braking speed. MD is the moving distance (m) of the vehicle during the braking time.

In the fourth step (S4), the amount of oil consumed by the single brake is calculated in combination with the vehicle travel record data and the single brake slip loss distance. Here, the vehicle driving record data includes: the average average fuel consumption and the average fuel consumption of the taxiing state. The specific calculation formula for the amount of oil consumed by a single brake is as follows: SBOF = SBLD * ( A – B )................... (Formula 3) where SBOF is the amount of oil consumed per single brake (ml) SBLD For the single brake gliding loss distance (m) A is the integrated average fuel consumption (ml/m) B is the average fuel consumption (ml/m) of the gliding state

In the fifth step (S5), in order to accumulate the amount of oil consumed by the single brake, the total brake consumption oil amount is obtained, and the average brake wear oil per unit distance can be calculated according to the total mileage of the vehicle and the total brake wear and loss oil. Quantity and output. For the driver, in addition to the amount of oil consumed by a single brake, the average brake loss and fuel consumption within the unit driving distance must also be calculated. The specific calculation formula is as follows: ABOF = (PBOF ∕ RTD) * 100................... (Formula 4) where ABOF is the average brake depletion oil quantity (L/100 KM) PBOF is the total brake depletion oil quantity (L) RTD is the total mileage of the driving (KM)

In a sixth step (S6), in order to accumulate the single brake coasting loss distance, obtain a total brake coasting loss distance, and calculate a fuel use efficiency of the vehicle according to the total brake coasting loss distance and the total mileage of the vehicle. Output. The so-called fuel use efficiency means the ratio of the actual driving distance to the theoretical driving distance without using the brake (ideal state). That is, the amount of oil consumed by the driver's fueling door should be able to make the vehicle travel longer distances in the ideal state without braking, but in the real environment, the vehicle travel distance will be less than the ideal value due to the brakes. The ratio will know the efficiency of the fuel consumed. The specific calculation formula is as follows: FE = RTD ∕ (RTD + TLD)................... (Formula 5) where FE is the fuel use efficiency RTD is The actual total mileage (KM) TLD is the total brake slip loss distance (KM)

In addition, at present, the general vehicle is equipped with a function device for calculating the average integrated fuel consumption, and the data can be obtained through the storage device 113. As for the taxiing average fuel consumption data, not all vehicles have this function calculation. If there is no such function, the vehicle enterprise can be preset in the storage device 113 at the factory.

In addition, the central control computing device 112 transmits the calculated single brake consumption oil amount to the output device 114, and the liquid crystal screen transmitted through the output device 114 is presented to the driver for reference.

In addition, the central control computing device 112 accumulates the calculated single brake coasting loss distance and the single brake consumption oil amount to the total brake coasting loss distance and the total brake consumption oil amount data. At the same time, the central control computing device 112 performs the calculation of the average depletion oil quantity and the fuel use efficiency according to the above formula 4 and formula 5 (please refer to the foregoing for the description of the formula 4 and the formula 5).

In addition, the central control computing device 112 updates the calculated average depletion oil amount and the fuel usage efficiency to the storage device, and simultaneously transmits the same to the output device 114 for presentation to the driver through the liquid crystal screen of the output device 114.

Through the above formulas and devices, the actual numerical results are as follows: (1) When the vehicle speed is braked by 60km/hr until the vehicle stops, and the vehicle travel distance is 250m during the braking cycle, the amount of oil consumed by the brake can be calculated; First, the initial braking speed is 60km/hr and the corresponding sliding distance is 600m, the ending braking speed is 0km/hr and the corresponding sliding distance is 0m. (3) Calculate the single braking and sliding loss distance is 350m. (600-0-250); (4) The average fuel consumption per 100 km of the vehicle is 8.2 L (converted to 0.082 ml/m) and the average fuel consumption per 100 km of the vehicle is 1.2 L (converted to 0.012 ml/m); 5) Finally, calculate the amount of oil consumed by a single brake to 24.5ml (350 * (0.082-0.012)). Since the estimated brake oil consumption is 24.5ml, if the oil price is NT$25/L, the brake will be used. The amount of wear and tear is NT$0.6125.

This is the largest difference between the first implementation and the second implementation.

Further speaking, in the second implementation mode, after the central control unit obtains the initial braking speed and terminates the braking speed, the central control computing device performs an instant calculation according to the sliding distance calculation formula to obtain the initial braking speed and terminate the braking. The speed of each car's taxiing distance. As for the calculation formula of the sliding distance, it can be set according to the different conditions of the consideration.
