example 1
[0097] Example 1: Set the weight of each sub-objective function to w d = 70%, w j =30%, to express that the driver hopes to drive the car in a mode that focuses on power and takes economical into consideration. Using the above method to optimize and calculate the optimal shift schedule of multi-performance with superior dynamic performance is as follows: Figure 5 shown.
[0098] Example 2: Set the weight of each sub-objective function to w d = 30%, w j =70%, to express that the driver hopes to drive the car in a mode that is more economical in energy consumption and at the same time takes power into account. The economically superior multi-performance comprehensive optimal shift schedule obtained by the optimization calculation of the above method is as follows: Image 6 shown.
[0099] Example 3: Set the weight of each sub-objective function to w d = 50%, w j =50%, to express that the driver has the same expectations for power and economy. The optimal shift law of p...
