The invention discloses a double-motor electric motor coach active brake energy recovering system and a control method. The double-motor electric motor coach active brake energy recovering system comprises a coach front distance measurement module and a coach back distance measurement module which are connected with a distance measurement module controller. The distance measurement module controller is used for calculating coach distance with a front vehicle and a back vehicle, the relative speed and safety distance according to distance measurement information sent in real time by the coach front distance measurement module and the coach back distance measurement module to form a distance measurement message to be transmitted to a whole coach controller at predetermined time intervals. The whole coach controller is connected with an accelerator pedal, a brake pedal, a first motor controller and a second motor controller. The whole coach controller is used for determining a control strategy in real time according to the received distance measurement message and being combined with received corresponding offset of the accelerator pedal and the brake pedal to form a control message. The first motor controller and the second motor controller are correspondingly used for receiving the control message broadcasted by the whole coach controller in real time, power outputting and brake energy recovering according to whole coach demands.
Description
technical field [0001] The invention belongs to the field of braking energy recovery of an electric passenger car, in particular to an active braking energy recovery system and a control method of a dual-motor electric passenger car. Background technique [0002] In recent years, with the increasingly serious air pollution caused by fossil fuels, national policies and more and more automobile manufacturers have begun to favor the development of new energy vehicles. Pure electric vehicles have developed rapidly due to their simple structure and non-polluting characteristics. As a family of new energy vehicles, new energy buses have achieved rapid development. In 2015, the sales volume of pure electric commercial vehicles in China reached more than 100,000, a year-on-year increase of nearly 10 times. The energy of pure electric buses comes from power batteries. It is more important to reduce the energy consumption of pure electric buses. Reducing the energy consumption of the ...
