AI Technical Summary

Technical Problem

Hybrid tractors have difficulty effectively managing their battery power under different driving conditions, resulting in insufficient or excessive battery power, which affects the vehicle's power assistance capabilities and fuel consumption.

Method used

By using a satellite positioning device and electronic map built into the tractor, the target balance power is calculated using altitude information. Combined with the charging and discharging power limit of the power battery, the power management strategy is dynamically adjusted to meet the needs of going uphill and downhill.

Benefits of technology

It enables reasonable control of battery power under different slope conditions, avoiding insufficient or excessive power, improving battery utilization efficiency and reducing fuel consumption.

Abstract

This invention provides a power management strategy for a hybrid tractor unit that can adjust the target balance range of the power supply in advance based on the altitude information ahead, thereby meeting the vehicle's subsequent uphill and downhill driving needs. The tractor unit has a built-in satellite positioning device that stores an electronic map. Based on the altitude information ahead, the vehicle's built-in module calculates the target balance power supply, and then manages the hybrid tractor unit's power supply according to this target balance power supply.
