Comparison of truck solutions

1) When optimizing with power performance as the target, on the basis of ensuring that the vehicle's fuel economy does not deteriorate, the vehicle's continuous shifting (0~80km/h) acceleration time is reduced by 3.2% when starting from the same place, and the direct shifting (0~80km/h) /h) The overtaking acceleration time is reduced by 13.7%, the climbing performance is also significantly improved, and the power of the entire vehicle is greatly improved;
2) When optimizing with fuel economy as the goal, on the basis of ensuring that the power of the car does not deteriorate, the car's speed is increased to 105km/h, and the fuel consumption per 100 kilometers at a constant speed of 40km/h is reduced by 17.64%, which is more than The fuel consumption per 100 kilometers under working conditions is reduced by 10.85%, and the fuel economy of the vehicle is significantly improved;
3) When weighing the optimization of power and fuel economy, on the basis of ensuring good vehicle power, the fuel economy of the vehicle is improved as much as possible. After optimization, the power of the vehicle has slightly decreased. The time for continuous shifting (0~80km/h) when starting from the same place is increased by 1.4%, and the time for overtaking acceleration in direct gear (30~80km/h) is increased by 3.8%. The fuel consumption per 100 kilometers at a constant speed has been reduced to varying degrees. The fuel consumption per 100 kilometers at a constant speed of 40km/h in the middle gear is reduced by 9.63%. The fuel consumption per 100 kilometers under multiple operating conditions of the vehicle is reduced by 7.12%. The fuel economy of the vehicle Significant improvement.
in conclusion
Through comparative analysis, in view of the current requirements for high-speed heavy-duty trucks and improved fuel economy, the matching scheme optimized based on the fuel economy objective function is more in line with market needs.
