Intelligent climbing control system, electric bicycle and climbing control method of electric bicycle

Abstract

The invention relates to an intelligent climbing control system, an electric bicycle and a climbing control method of the electric bicycle. According to the main technical characteristics, the intelligent climbing control system comprises a bicycle data acquisition unit, a data analysis unit, a climbing decision unit and a motor control unit, and is mounted in the intelligent climbing electric bicycle; the climbing control method comprises the following steps: whether the bicycle line circuit reaches an initial current limiting value or not and whether the rolling handle voltage exceeds an effective highest value or not are judged; when the bicycle line circuit reaches the initial current limiting value and the rolling handle voltage exceeds the effective highest value, a climbing recognition stage is started; if the climbing torque is insufficient, a preset climbing program is started; when the exit requirements of the climbing program is met, an initial program is recovered. Through adoption of the intelligent climbing control system, the climbing road conditions can be intelligently recognized, so that the electric bicycle can not only be driven on level roads but also has sufficient power while climbing, the using performance of the electric bicycle is effectively improved, and the demands of a large number of users are better met.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, and relates to an intelligent climbing control system, an intelligent climbing control method and an electric vehicle. Background technique [0002] The traditional electric vehicle control mode is relatively simple, and the output current is adaptive within the current limit value according to different road conditions. Since the current limiting value is unique and immutable, when the electric vehicle climbs a steep slope, the climbing torque will be insufficient due to the limitation of the current limiting value, the power cannot be increased, the speed will drop, and the efficiency will decrease. If the current limit value is set high enough to meet the climbing requirements, the starting current will be too large, and the allowable load on flat roads will increase. When the load is heavy, the output current will remain at a large current value for a long time, causing the motor to...
