A control method, device and system for vehicle energy recovery

Abstract

The invention discloses a control method, device and system for automobile energy recovery, and belongs to the technical field of automobiles. The method comprises the following processes of judging whether a gearbox completely executes the operations of upshifting and downshifting or not, if yes, controlling a motor to enter an electricity generation state, converting the kinetic energy of the motor and the kinetic energy of the gearbox into electric energy, and storing the electric energy in batteries for standby application; and monitoring whether the synchronous rotational speed difference of the gearbox is in a preset range or not, if yes, stopping electricity generation and controlling the gearbox to execute the operation of putting in gear, else, and performing synchronous speed adjustment on a primary power source so as to enable the synchronous rotational speed difference to reach the preset range and enable the batteries to recover the electric energy produced by the motor, wherein the primary power source is the motor. Through the adoption of the control method, device and system disclosed by the invention, energy produced in the upshifting process of the gearbox is stored and used as the electric energy required for upshifting after the completion of gear shifting, so that the efficiency can be improved, and the energy consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method, device and system for energy recovery of automobiles. Background technique [0002] As the world's fossil energy resources are becoming less and less and pollution is becoming more and more serious, reducing energy consumption and reducing emissions has become an urgent problem to be solved in today's society. With the development of society and economy, the urbanization process of developing countries is accelerating, which leads to the rapid growth of urban car ownership, resulting in aggravated urban traffic congestion, increased energy consumption, and the proportion of air pollution caused by automobile emissions in urban air pollution is increasing. come higher. While motor vehicles bring convenient transportation to people, they also bring many environmental problems that endanger human health, and some environmental problems even cause catastrophic ...

AI Technical Summary

Problems solved by technology

[0004] However, the recovered energy obtained only through the above two ways of energy recovery is relatively limited. It is necessary to provide a control method, device and system for vehicle energy recovery in addition to the above two ways of energy recovery, so as to increase the efficiency of vehicle recovery. energy and driving range
