[0050] Refer figure 1 This embodiment provides a vehicle shifting method, comprising the steps of: S10: Access user preference parameters.
[0051] Specifically, the degree of user preference degree of preference parameter comprises time shift value q 1 The economic engine of the degree of preference value q 2 And the degree of preference value of the engine power q 3 , These three values in the shift by the driver of the vehicle a user input to the vehicle controller input, and the three values are greater than 0 and less than or equal to 1, numeral 1 denotes the vehicles most care properties, the smaller the number indicates the species the properties of the vehicle do not care, as well as to prevent users all attributes are set to 1, lead to the respective property care vehicle occurs, the sum of the degree of preference attributes vehicle user configurable limit is 1.5, the user can not fill level of preference for each attribute of the vehicle , if the default fill attributes for each vehicle are the same focus, its values are 0.5.
[0052] S20: acquiring an evaluation score.
[0053] Specifically, the evaluation score evaluation score including time shift, engine power and economic evaluation score evaluation score of the engine;
[0054] Of i (i = 1,2, ..., 5) of the gear shift time evaluation score = | -i when the vehicle is not the number of gear shift | / 4;
[0055] Of i (i = 1,2, ..., 5) an engine speed dynamic evaluation score = f T ( i * n transfer ) / max {f T (N motor }
[0056] Economic evaluation score of the engine i (i = 1,2, ..., 5) = min {f profile b (N motor )} / f b ( i * n transfer );
[0057] To be noted that the engine of the vehicle is outside the characteristic properties of the engine, i.e. an engine output torque T motor And fuel consumption b motor With the engine spindle speed N motor Change characteristics, which are denoted as a function of T motor = F T (N motor ), B motor = F b (N motor ); Built information for the user input, the user only needs to select the configuration according to the engine driving the vehicle, further the above formula η i When the corresponding transmission ratio of the transmission gear i.
[0058] S30: constructing a first judgment matrix.
[0059] AHP-based configuration, first, according to the degree of user preference time shift, engine power, engine economy and other vehicle attributes judgment matrix A, which is configured as follows:
[0060]
[0061]
[0062] Among the formulas, a ij For the first judgment matrix No. j column elements, Q i(j) Represents user preference parameters, including shift time preference value, engine economy preference value and engine dynamic preference value.
[0063] S40: constructing a second matrix is determined.
[0064] The particular choice: a gear, second gear, fifth gear ......, various options are again calculated is determined for each property matrix B j (J = 1,2 ... 5), which is calculated as follows:
[0065] A respective gear shift time attribute determination matrix B 1 :
[0066]
[0067]
[0068] Wherein, b1 ij The first column element element in the corresponding second judgment matrix, C1 i (I = 1,2 ... 5) for each vehicle attribute (shift time) of a normalized evaluation scores 1, similarly to the respective other vehicle determination matrix properties are also calculated in accordance with the method described above, can be alternatively change stop judgment policy for each attribute matrix B 1 , B 2 , B 3. . . . B 5;
[0069] Here should be noted that B i (I = 1,2, ..., 5) represents a second matrix is determined at different gear i.
[0070] S50: determining a first judgment want to change gear according to the matrix and the second matrix is determined.
[0071] Specifically, first the element B is the second matrix is determined i (I = 1,2 ... 5) column vector normalization, and then seek the line, the weight vector w to give i Similarly to the first matrix is determined column vector normalization, and then seek the line, obtain the weight vector c i , Whereby the respective gear weights Kj:
[0072] K j = W i (j) c i
[0073] In K j For the weight of the JU, W i For the second weight vector, J is the gear, C i Finally, in descending order of priority according to the size of the gear weights, the maximum value of the option program for gear shift; a first weight vector.
[0074] The vehicle shifting methods give full consideration to the characteristics of the user's preference and the degree of the engine, shifting gears to select the analytic hierarchy process, greatly improve the driving driver satisfaction, passenger comfort, and improved engine performance, energy conservation.
[0075] like figure 2 , An embodiment of the present invention further provides a vehicle shift apparatus 10 includes a first obtaining unit, configured to obtain the degree of user preference parameters; wherein said parameters comprise time shift value preference degree, the preference degree of the engine economic value engine power and the degree of preference value.
[0076] Specifically, the degree of user preference degree of preference parameter comprises time shift value q 1 The economic engine of the degree of preference value q 2 And the degree of preference value of the engine power q 3 , These three values in the shift by the driver of the vehicle a user input to the vehicle controller input, and the three values are greater than 0 and less than or equal to 1, numeral 1 denotes the vehicles most care properties, the smaller the number indicates the species the properties of the vehicle do not care, as well as to prevent users all attributes are set to 1, lead to the respective property care vehicle occurs, the sum of the degree of preference attributes vehicle user configurable limit is 1.5, the user can not fill level of preference for each attribute of the vehicle , if the default fill attributes for each vehicle are the same focus, its values are 0.5.
[0077] The second acquiring unit 20 for acquiring an evaluation score; wherein said evaluation score evaluation score comprises a time shift, engine power and economy of the engine evaluation score evaluation score.
[0078] Specifically, the evaluation score evaluation score including time shift, engine power and economic evaluation score evaluation score of the engine;
