Energy electric car with a multistage gearbox feedback control method and control system

The present invention provides an electric vehicle power transmission with multi-level feedback control method and a control system, the brake pedal sensor, accelerator pedal sensor, a vehicle speed sensor and the brake motor sensor signal, acceleration signal, vehicle speed, motor output case of energy delivered to the feedback control means, energy feedback control means determines the energy feedback information according to whether the received, such as the need for energy feedback, the feedback energy feedback control means according to real-time data communication with the energy of the motor controller, energy feedback control energy recovery means into the storage means by conduction system. The invention realizes the multi-stage gearbox with an electric vehicle energy feedback, energy feedback for different gear, the vehicle is in different circumstances, to achieve maximize energy recovery, and does not affect the vehicle comfort, it also does not need to increase electric car motors to achieve a multi-stage gearbox with energy feedback device.
