The invention discloses a motor control device of a dual-power electric bike. A main storage battery and an auxiliary storage battery are mounted on the electric bike, and the auxiliary storage battery is mounted on a storage battery support on the side face of a bike body of the electric bike. The motor control device further comprises an electronic compass and a motor controller, and during riding of the electric bike, the motor controller controls the power supply state of main storage battery and the auxiliary storage battery on a motor and adjusts running of the motor after processing information of the running state of the electric bike and the running state of the main storage battery and the auxiliary storage battery. By the arrangement, the motor is controlled according to a set optimization program, the running state of the electric bike is greatly improved, and comfortableness in riding is improved, service of the storage batteries is greatly optimized, and service life of the storage batteries is prolonged while travel distance of the same is increased.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a motor control device. Background technique [0002] The riding state of electric vehicles in the existing market is completely controlled by the rider according to the road conditions and the running state of the electric bike itself. Due to the difference in the rider's perception, the control is not accurate enough, so the running state of the electric bike and the riding state Comfort levels are not good enough. [0003] In addition, electric vehicles have different requirements for power supply under different operating conditions. For example, when starting and climbing, the motor needs to increase torque. At this time, the power supply needs to maintain a stable high-current output. At low speed, the power supply is normal A stable current is enough, but when going downhill, the motor decelerates and the motor torque decreases, so a large current is...
